     This, the twenty-fifth in this series of papers and reports,
examines trends in light-duty vehicle fuel economy and technology
usage through model year 1993.


II.  Introduction

     Light-duty automotive technology and fuel economy trends are
examined herein, as in preceding  papers  in this series,  [1-24],*
using the latest and most complete EPA data available.  The source
database was frozen in December 1992.

     Through model year  1991,  the fuel economy and vehicle sales
database used  for  this  report was formed  from the most  complete
database  used  for MPG   standards  and  Gas  Guzzler  regulatory
compliance purposes.  For all practical purposes, these databases
are stable and are  not expected to change  in the future.  For model
years 1992 and 1993, the fuel economy database used  for this report
was  formed  from  the  final  compliance   data  if  available  and
augmented with  data from the database used  for the government's
fuel economy public information programs:   the gas mileage Guide
and the MPG  labels that  are placed on  new vehicles.   The vehicle
sales database  for 1992  and 1993  used  for this report was formed
from the  compliance and  information databases,  adjusted  to take
into account sales  data available in trade publications at the time
the database was frozen.

     The MPG data in this series and this  paper are unadjusted data
values,  with no  correction  factors for  laboratory to  on-road
shortfall  or  "test  procedure  adjustment."    Because  the  test
procedure adjustments have not been  made,  the MPG  values in this
report are always  lower  than  those reported by the Department of
Transportation.  This  difference  for the  combined  car  and truck
fleet has averaged 0.3  MPG for the last 14 years.  This systematic
1  percent difference  does* not  influence the fuel economy  and
technology trends  in  this report.   Where only one  MPG  value is
presented, it is 55/45 combined MPG.  All vehicle weight data are
based on inertia weight class  (nominally curb weight plus 300 Ibs) .
The light truck data in this paper include vehicles classified as
light-duty trucks  with gross  vehicle weight ratings (GVWR) up to
8,500 Ibs for all years shown.

     This paper  includes  an estimate of  0 to 60 MPH acceleration
time, calculated from engine rated horsepower and vehicle inertia
weight, as in reference 25, and a top speed index similarly
      Numbers in brackets denote references listed at the end of
      the text.

I.    Summary

     This, the twenty-fifth in this series of papers and reports,
examines trends in light-duty vehicle fuel economy and technology
usage through model year 1993.


II.  Introduction

     Light-duty automotive technology and fuel economy trends are
examined herein, as  in  preceding  papers  in this series, [1-24],*
using the latest and most complete EPA data available.  The source
database was frozen in December 1992.

     Through model year  1991,  the fuel economy and vehicle sales
database used  for  this  report was formed  from the most complete
database  used  for  MPG  standards  and  Gas  Guzzler  regulatory
compliance purposes.  For all practical purposes, these databases
are stable and are  not expected to change  in the future.  For model
years 1992 and 1993, the fuel economy database used for this report
was  formed  from  the  final  compliance   data  if available  and
augmented with  data  from the database used  for the government' s
fuel economy public  information programs:   the gas mileage Guide
and the MPG  labels that  are  placed on  new vehicles.   The vehicle
sales database  for 1992  and  1993  used  for this report was formed
from the  compliance  and information databases,  adjusted  to take
into account sales  data available  in trade publications at the time
the database was frozen.

     The MPG data in this series and this  paper are unadjusted data
values,,  with  no  correction  factors for  laboratory to  on-road
shortfall  or  "test  procedure  adjustment."    Because  the  test
procedure adjustments have not been  made,  the MPG values in this
report are always  lower  than those reported by the Department of
Transportation.  This  difference  for the  combined car  and truck
fleet has averaged 0.3  MPG for the last 14 years.  This systematic
1  percent difference  does  not  influence  the fuel economy and
technology trends  in this report.   Where only  one  MPG value is
presented, it is 55/45 combined MPG.  All vehicle weight data are
based on inertia weight  class (nominally curb weight plus 300 Ibs)  .
The light truck data in this paper include vehicles classified as
light-duty trucks  with  gross vehicle weight ratings (GVWR) up to
8,500 Ibs for all  years shown.

     This paper  includes  an  estimate of  0 to 60 MPH acceleration
time, calculated from engine rated horsepower  and vehicle  inertia
weight, as in reference 25,  and a top speed index  similarly
      Numbers in brackets denote references listed at the end of

calculated using an  analysis  of  actual vehicle performance data.
These  estimates   provide  quantitative   "indexes"   of  vehicle
performance capability.

     Vehicle  classification  as to  vehicle type, size  class and
manufacturer/origin  generally follows fuel  economy label,  Gas
Mileage  Guide,  and  CAFE  protocols;  exceptions are  listed  in
Appendix A.  In some  passenger car tables,  Large  Sedans and Wagons
are aggregated as "Large," Midsize Sedans and Wagons are aggregated
as "Midsize," and "Small" includes all other cars.  Pickups, Vans
and Utility Trucks are  sometimes each subdivided as "Small,." and
"Large."   The truck  classification scheme used  in  this paper is
explained in reference 14.

     Grouping all vehicles into classes and then  constructing time
trends of parameters of interest like MPG can provide interesting
and useful results.   The results,  however, are a strong function of
the definitions used to define the classes.  Nowhere is this more
important than in the definition of Domestic and Import or Domestic
and European and Asian vehicles used in this series of papers.

     Classes based on other  definitions are possible and results
from these other classifications may  also be useful.  Some other
classification scheme concepts, not all mutually exclusive, could
be:

     Grouping of vehicles made in the U.S.A.
     (and/or in Canada and/or in Mexico);

     Various percents of domestically added value;

     Grouping by who markets vehicles  instead of who makes them;

     Grouping based on where the profits or losses wind up; and

     Grouping by whether or not vehicles are assembled with union
     or non-union labor.

     This report did  not analyze a sensitivity to  class definitions
because the magnitude of the effort is too large for this report,
and because  the basic reasons for  investigating these different
classification schemes have less  to  do with MPG trends than they do
with job policy and/or industrial policy, which are not the subject
of this report. (The initial reason behind the Domestic  and Import
definition in the fuel economy standards  legislation was  based on
concern with jobs, not on any reason dealing with MPG technology.)

     Appendix  B lists the  model year  1992  nameplates  and their
average  MPG as  of the  data freeze  date.   Appendix C  presents
similar data  for 1993.

III. General Car and Truck Trends

      Table  1  gives  characteristics  of  passenger  cars,  light
trucks, and  all light-duty vehicles (cars and  light  trucks)  for
model years  1975 to  1993.   Figures 1 through 4  show  some of the
general time trends in some of the data from Table 1.

     The 1993 MPG for cars, trucks,  and  both:  28.0,  20.8, and 25
are not greatly changed from  those  of  1992 and,  in fact,  are all
within 1 MPG of the corresponding data since 1985.  Figures 3 and
4 show  that average vehicle  weight is  creeping up.    Cars have
gained more than 6  percent  in  weight since  the minimum in 1987 and
the more obvious truck trend shows an 11 percent increase since
then.   Since  the  average MPG  has  remained  constant  and  not
decreased in "response" to these weight increases, the 1993 car and
truck fleets are the most efficient ever on the basis of ton-MPG.

     There  is  substantial  experience  now  with  the current fuel
economy standards.   In  the more  than 15  years for which fuel
economy standards have been established,  it is of interest to look
at what the response of the industry has been to the requirements.
Figure  1  shows that  the  car and  truck fleets  have  essentially
attained the regulatory requirements on a fleetwide average basis.
Figure 2 shows  this  data  in more detail.   The  type  of standards
that exist now  involve a substantial penalty  for being below the
standards   and   no  long-term   benefit   for  being   above  the
requirements.   Other  influences,  including market forces such as
the cost of gasoline and consumer preferences being equal, such a
standard would  tend  to  make all manufacturers  approach the same
value—the  standard.   Considering manufacturer  groups  as  an
indication,  Figure  2 indicates  that the trends roughly  show an
approach toward similar values.   What Figure 2 also shows is that
the "rising  tide"  (the performance  of  the Domestic manufacturers
since  1975)  does not  "lift  all  ships"  (the  other  manufacturer
groups).

     Clearly, the MPG-related vehicle attribute which has changed
most dramatically in the last decade is performance. Figure  5 uses
an  estimate  of  0  to 60 MPH acceleration time  as the performance
indicator and Figure 6 likewise uses an analytical  estimate of top
speed  as  the  performance  metric.    In addition  to the trends
depicted on Figures 5 and 6, Figure  5 provides an estimate of what
the MPG of  the car  fleet  would  be  if the performance  were kept
constant at the level of that  of  1984.  A fleet MPG in excess of 30
MPG has been foregone in favor of higher performance.

     Figures 7  and  8  present  the average performance,  weight and
volume  characteristics  of  1993  passenger  cars  in different MPG
bands.  The results show  that  vehicles with high MPG  have less
performance, are lighter,  and tend to have  smaller  interior volume
than vehicles with low MPG.

                              Figure 9
     Vehicle performance depends strongly on power-to-weight ratio.
If, as  indicated earlier,  weight is  trending upward,  then the
reason for  the increase  in  performance must  lie  with increased
horsepower; Table 1 indicates this upward trend in  engine power.

     Engine power can be increased by increasing displacement and
by increasing specific power  (HP/CID).  Figure  9 shows trends in
HP, CID,  and HP/CID since 1975.  For the past 10 years or so, the
trend in HP has been up.   CID has not shown a major upward trend
being close to  170  CID for several years  now.   In contrast, the
trend in HP/CID has been dramatic.  Specific power has increased by
74 percent since  1976,  and  by 45 percent since the HP minimum in
1981-82.

     Since the  early 1980s,  therefore,  the substantial trends in
performance-related metrics are due to increased horsepower which
has been achieved primarily via increased  specific power.

-------
                                -11-
IV.  Technology Trends

     There are technology changes that can explain the trends seen
previously in specific power.  One way to increase specific power
is the use of  more than two valves per cylinder.   Three or four
valves per cylinder can increase  an engine's volumetric efficiency
leading to more horsepower.  The benefits of this technology can be
used in more than  one  way.   If the  displacement  of  the engine is
kept constant,  multi-valve engines  can produce more  horsepower
yielding  increased vehicle  performance.    On the other  hand,
increased  specific power  allows use of  a  smaller displacement
engine  with  benefits   in  fuel  economy,  while  keeping  vehicle
performance constant.   Because  the  benefits of a  technological
change can be  used for either better performance or  better fuel
economy,  it  is not  surprising  that projections  of future fuel
economy capabilities vary  due to different  assumptions about how
presumed future technological improvements will be used.

     In order to track the trends in multi-valve  engine use, the
database was  augmented with information  about the number of valves
per cylinder.   The  information   was based  on published sources
[32,33,34] to the  extent possible, augmented by other sources.[35]
Data were  available back  to  1986 that  were useful for studying
trends.   Only  the  passenger car  database was  augmented with the
valves per cylinder data.

     Multi-valve engines do have  higher  specific power.  Figure 10
shows that 4-valve engines have the highest HP/CID,  more than 1.0
HP/CID;  3-valve engines,  intermediate  values (approaching 1.0
HP/CID); and  2-valve engines,  the lowest (approaching 0.8 HP/CID).
Notice, also that there is  an  upward  trend  in HP/CID in all three
groups.   Since 1986,  for  example, the  specific power  of 2-valve
engines has increased  11 percent.  More information on the trends
in valves per cylinder can be found in Appendix D.

     Greater market penetration of multi-valve engines with higher
specific power could be responsible for the fleetwide increase in
specific power.  This  is shown in Figure 11, which  indicates that
multi-valve engines now exceed  35 percent of the car  market and
most of them are 4-valve engines.

     Separate from any  other knowledge about manufacturers' product
plans, do the data indicate that  4-valve engines are going to rise
to a dominant market share?  This technology replacement question
is obviously of great interest.   Figure  12 compares  4-valve market
penetration  to two other technologies which have  effectively
replaced  prior  technologies:    port   fuel  injection  replacing
carburetion,   and  front-wheel  drive  (FWD)   replacing  rear-wheel
drive.  Figure  13  compares 4-valve  market  penetration to that-of
technologies  which "came  and went," i.e.  were unsuccessful  in
replacing other technologies:  throttle-body fuel injection  (TBI)

losing out to port fuel injection, and 3-valve engines losing out
to 2-valve and 4-valve engines.

     An answer to  the replacement question is  not  apparent from
looking at Table  1  and Figures  12 and 13.  It is  likely that one or
two more years of data are necessary since although Figure 13 looks
subjectively like a better fit, the 4-valve curve could increase to
market dominance like PFI and FWD or  it  could die out like TBI, 3-
valve  engines,   and  Diesels,   or it   could  stabilize  at  some
intermediate value near 50 percent.

     An important  observation  from Figure  12 is  that technology
replacement in the  automotive industry takes time.  For PFI and FWD
the times to exceed 80 percent  of the market were 12 and 13 years,
respectively.  This  kind of a time constant needs  to  be  kept in
mind when studying  possible future scenarios for  emissions and fuel
economy, especially if changes in either are predicated on new or
replacement technology.

     Appendix  D provides  additional   figures  and  tables  that
describe technology trends.


V.   Fuel Economy Improvement Potential

     In references  20 and 24, MPG capability contained in the then
current fleet was examined using a method called the best-in-class
(BIG) analysis.   In a BIC analysis, one  divides the baseline fleet
of vehicles into classes and then examines  the MPG characteristics
of each class. If  one selects the MPG performance of the best cars
in the class  (hence  the name),  one can  recompute  a  fleet average
using the best cars'  MPG and the same relative sales proportions of
the fleet that existed  in the baseline.   The BIC analysis was one
of the methods used to investigate future fleet MPG capability when
the original  fuel economy standards were set.

     The classes may be generated  in any way,  but the most common
classes are those  that  are  based on  the car classes used for the
EPA/DOE Gas Mileage Guide and the  inertia weight classes used for
EPA's  emission  certification  program.    We have  chosen  to  use
inertia weight  classes, since  if the   sales proportions  in each
inertia weight class (IWC) are held constant, the average weight of
the fleet does not change.

     One potential problem with a BIC analysis is that the high MPG
cars  used  may  be  unusual  in  some way—so   unusual  that  the
hypothetical  fleet made up of them, although a high  MPG fleet, may
be deficient  in some other attributes considered desirable by car
buyers.  We  chose  to look at both the  best and the worst cars in
each class to see  how the best and the worst-in-class (WIC) cars
differed from the  average car  in each class.

     Table 2 shows the results  of  the  BIG analysis for 1993.  If
the fleet were  comprised of cars with the MPG  of  the best dozen
cars  in  each class,  the fleet  would  be  30.4  MPG,  more  than 8
percent better than the 28 MPG average of the current fleet.  The
cars  that  comprise the  best  dozen in  each  class are  listed in
Appendix E.  The list of vehicles considered best (or worst) in
class includes as one entry vehicles with different  nameplates, but
identical powertrains and fuel economy  such as the  Ford Taurus and
Mercury Sable.   The list of vehicles also excludes vehicles  sold by
small volume importers.  The BIG cars represent 21 percent of the
market while the WIG cars represent only 8 percent.  The BIG  cars
are  actually fairly  close to  the average  in interior  volume,
performance, and size mix.   The  biggest departure from the average
for the BIG  cars is a  larger  share of  manual transmissions.  BIG
cars  are therefore much  more representative of the  average cars
than are the WIG cars.

     Of course, the BIG analysis is sensitive to the selection of
the best cars.  If the  BIC  analysis  is based on the best five or
best one car in each class instead of the best dozen, the fleet MPG
projected changes from 30.4  MPG  (best 12), to 31.8 MPG  (best 5), to
33.6 MPG (best  1).  Further information from the BIC analysis is
included in Appendix E.   The results  in this  appendix use the same
methods described in  reference  24.   Appendix F contains detailed
data by weight class.   Appendix G contains data stratified by car
and  truck  class,  and Appendix  H contains  data  arranged  using
cylinder count.

     The best-in-class analysis  is only one of several methods that
can be used  to  make inferences  about the potential for obtaining
other fuel  economy  levels.   The major  use of such methods  is to
investigate  the potential  for  higher than  current  fuel economy
levels.  There is no interest in projections  of  lower than current
fuel economy levels.  In addition to  the best-in-class approach,
regression analysis,  learning curve  approaches, the menu method,
the Delphi  method,  and engine map-based methods 'are  the primary
methods used.

     Using  regression analysis  in  determining  the relationship
between  fuel  economy  and  variables  that   can   explain  it  is
frequently used.  Armed  with an equation that describes MPG, one
can alter one or more  of the variables considered to be independent
and examine  what  the  MPG effect would  be.   Such approaches have
been used,  for example, to infer the  effect reduced  weight and
reduced engine  displacement would have on  fuel economy.   In most
regression studies,  the variables and the functional forms for them
are very often not based on any physical or engineering hypothesis,
so the mechanistic  cause-and-effect  relationships  are not sought
and, consequently, not found.

     Like best-in-class  analyses, the regression approach cannot
infer what would be the effect of a technical change that was not
present  in  the  database,   or  inaccurately  represented in  the
analysis with respect to its causal  strength.  For  example, if the
original database did not contain the results for shutting off the
engine at idle  or multi-valve engine use,  then both the best-in-
class  and  the regression methods would fail to predict the MPG
benefit of  using  these  technologies.   Another limitation to both
the best-in-class and regression analysis methods  is that neither
method predicts when the predicted MPG improvement can be attained.

     Learning  curve studies have been  used  a great deal in cost
studies, but not very much  in  MPG  projections. The basic theory
used is that the more  a given process is done, the more efficiently
it can be performed.   In cost studies, "more"  is  translated into
cumulative production and the "more efficiently" is  translated into
piece  cost  for a mass-produced item.  Many  manufacturing systems
show behavior that can be modeled well  enough to make projections

-------
                                -17-


concerning the cost reduction due  to  each doubling of cumulative
production volume.  When the "more-efficiently" variable is changed
to fuel consumption (1/MPG) , the fuel consumption versus cumulative
production approach yields  results that can be interpreted to imply
that since 1975, fuel economy has  improved by at  least 8 percent
for each  cumulative  doubling in production.  Extrapolating that
trend into the future implies that  shortly after the year 2000 the
new car fleet could be projected to exceed 30 MPG.  Learning curve
analysis,   like  best-in-class   and regression  analysis,  cannot
explain from  an engineering perspective  how the  forecasted MPG
improvement will occur.   In addition,  like any time series study,
the results  can be  confounded  by time  trends  in  other  factors
affecting MPG.

     One of the difficulties with  the learning  curve approach is
that the improvements in fuel economy  seen over time may be due to
reasons other than simply the industry getting better at doing the
same thing.   An example  could be the  introduction of  new and
different technology.  The  improvement seen over time could be due
to  increased penetration  into  the  market  of  new,  more  fuel
efficient technologies  and the  learning  curve approach  might be
inappropriate.

     In order to focus  on this issue we  identified a  subset of
vehicles that were  nominally the same  and tracked their change in
MPG over time.  Thus,  a "single vehicle type" is identified and any
improvements  in  MPG  would be  consistent  with  a  learning  curve
explanation.

     The analysis compares  all cars against just the subset of cars
at  the   same  weight,   front-wheel  drive,  horsepower   range,
transmission type, fuel metering and number of valves per cylinder.
The figure of merit used was the ratio of the MPG  in 1993 to the
MPG in 1981.   The results are shown in Table 3.

     As  the vehicle  group becomes  more and  more  defined,  the
improvement over  time does not go away,  it,  in fact,  increases.
This means that the learning curve method cannot be dismissed as an
approach to investigating future MPG improvements.  Further studies
are probably necessary before  numerical values of  learning curve
MPG improvement factors can be determined, however.

     The menu method  derives its name from the list of fuel economy
improving technologies or  approaches  available.  In order to use
the method,  the technological characteristics of the baseline fleet
are used  as the starting point.   To  make a  future projection of
higher MPG, the fleet penetrations of technologies that .result in
fuel economy improvements are increased, and new technologies can
be  added.   The  addition  of  new technologies  is  an  important
characteristic  of this  approach.   If  a fuel  economy  improving
technology  (e.g., a lean  burn   engine or  a  6-speed  automatic
transmission  with lockup)  can  have  a  numerical   fuel  economy
improvement assigned to it, then on paper it can be introduced into
the  fleet  and its  percent  market  penetration  increased  with
resulting fleet fuel economy  improvements.   Points of (sometimes
controversial)  discussion  with  the  menu   method  are:  which
technologies should be on the menu, what the fuel economy impact of
each technology is, how to model the results of combining more than
one technology,  and  how fast the technologies on  the  list can
penetrate into  the new car fleet.   Much of  the analysis work for
recent studies of automobile fuel economy [28,29,30] have been of
this type,  and all have been directly or  indirectly  influenced by
work supported by the Department of Energy.

     The Delphi method is another methodology that can be used to
study  future  fuel economy levels.   In this approach a  panel of
experts  is  formed, each  of which possesses  in-depth knowledge of
the subject area.   The  panelists  independently answer questions
that  deal with fuel economy potential.   After the results are
tabulated,  the answers are sent back to each of the  panel members
so  that  the panelists can  see how their answer compared to the
consensus  of,  or the distribution of,  the  other answers.   The
panelists are then given a chance to  change their answers, and the
second-round  results  obtained are  generally  considered to  be
representative of "informed opinion" on the subject.  This type of
methodology requires the  least  amount of experimental  data and
tends to  be the most subjective.

     The  engine map  method utilizes  hard data about the measured
fuel  consumption  of  an engine as a  function of engine speed and
engine load (an engine map)  and  vehicle characteristics such as
weight,  drag coefficient,  frontal area, the  rolling  resistance of
its  tires,  and  the characteristics  of  its  transmission,  and
predicts the fuel consumed over a given vehicle duty cycle. If the
duty cycle  is the same one that is used to generate MPG values for
the government's regulatory and public information programs dealing

-------
                              -19-


with MPG, then forecasts can be made of likely MPG improvements due
to changes in engine efficiency or vehicle characteristics.  Most
of the  public development of  this method was  done by  the U.S.
Department of Transportation  (DOT).[31]  This method uses, as input
data, fuel consumption maps and so is limited by the availability
of engine maps.  DOT did generate  several engine maps for analysis
purposes, but the engine mapping  work stopped more than 10 years
ago.   Recently,  some work in modeling has been  reported [36,37]
that utilizes simplified,  generalized engine maps.   This approach
also shows promise.

     All  of  the methods  for  making  estimates   of  future  MPG
potential have pros  and cons.  A robust approach could utilize some
or   all   of  the   usual   analysis  methods,  gaining   improved
understanding from  both the similarities and differences  in the
resultant projections.


VI.  Trends by Market Segment

     Table 4 shows the characteristics of Domestic, European, and
Asian passenger cars. The  MPG performance of the car groups shown
in Figure 2  indicates that the European cars trail the Domestics by
about 2 MPG and  the  Asians by about  5.5  MPG  and  this pattern has
held since 1990.  The Europeans (up more than 300 Ibs in the last
5 years) and the Asians (up more than 200 Ibs)  are gaining weight
faster than the Domestics (up 100 Ibs) in the same time period.

     European   cars  have   the   highest   weight,   horsepower,
performance, and specific power.  Asians cars lead in fuel economy,
ton-MPG, and  cu-ft  MPG.   Domestic cars  lead in  interior volume,
CID,  and cu-ft ton MPG.

     The data in Table 5 for  Domestic  and Import light trucks show
that since 1981, Domestic trucks  have increased  from 18.2  MPG to
20.3 MPG (+12 percent) even though MPG has been fairly constant for
the past few years.   In contrast, over the same time period, Import
trucks have decreased from 27.3 to 23.0 MPG (-16 percent).   These
trends  show another  example of  the  effect of  the  current MPG
standards—different   manufacturer   groups'   MPG   performance
approaching the standard over time.  The  trend with trucks is more
pronounced than was  the  trend with passenger cars noted earlier in
this report.

     Figure 14 and Table 5 show that Domestic trucks and Asian cars
have experienced the largest growth  in market share since 1975,
their growth coming  at the expense of Domestic cars.

     The sales trends shown in Figure  14 and Tables 4  and 5 for the
five vehicle groups  can be combined with the  fuel economy values of
the groups to yield  a relative total fuel consumption value,

                               Figure 14
assuming all  vehicles travel the  same distance.   Data  comparing
1975  and  1993  are  shown  in  Table  6,  normalizing  total  fuel
consumption to 100 for each year.

     Since 1975,  Asian cars have quadrupled their relative share of
the total  fuel consumed  by  the light  fleet,  Import trucks  have
tripled their share,  and Domestic trucks have increased their share
from one-fifth  to one-third  of the total.   Changes in  relative
share reflect changes  in  sales  and fuel economy.

     If actual fuel  consumption, not normalized fuel consumption,
is the  measure only the  Domestic  and  European car classes  have
reduced fuel  consumption  since 1975.  If all classes had reduced
actual  fuel  consumption  as much  as the  Domestic car class  has,
today's fleet would  use less than one-half of the fuel used by the
1975  fleet.    Changes  in actual  fuel consumption  also  reflect
changes in sales  and fuel economy.

     Table 7 presents another way to compare cars and light trucks
in this case by size class.  In the 15 size classes shown in Table
7, Domestic vehicles lead in six,   European vehicles lead in one,
and Asian  vehicles  lead  in  eight.  The  best cars  are  sometimes
dramatically  different from the worst cars in  MPG,  comparing the
results from  Tables  7  and 8.

     Figures 15  through 18 show ways  in which the  three market
segments are similar and ways  in which they are different.  Figure
15 reinforces the earlier discussion about weight trends, showing
that for  the European  and Asian groups, the  trend has  been an
increasing one for more than 10 years.

     Figure 16 indicates that  increased volumes have accompanied
the  European  and Asian  cars'  increased weight,   although  the
Domestics still have the largest volume.

     Figure 17 shows that in HP/CID, the European and Asian trends
are  essentially  identical  having  increased and  been  above  1.0
HP/CID for some years now.   The Domestics trail  in HP/CID but also
show an increasing trend.
     As seen in Figure 18 all three groups show very similar trends
in terms of performance especially in the last 3 or 4 years.

VII. Conclusions

     1.   The 1993 MPG values for passenger cars, light trucks, and
both together is little changed from last year and are all within
1 MPG of the values since 1985.

     2.   For roughly the last decade, the most significant trend
has been increased vehicle performance.

     3.   Increased  vehicle  performance  has  been  achieved  by
increased horsepower  which has  been  achieved  primarily  due  to
increased specific power.

     4.   Since 1987,  vehicle weight has increased by  6 percent for
cars and 11 percent for trucks.

     5.   Engines with more than  two valves per cylinder exceed 35
percent of the market; most of these have four valves per cylinder.

     6.   Technology replacement in the automobile industry takes
more than a decade to accomplish.

     7.   There are  several methods that  can  be used  to assess
future MPG potential.   A best-in-class  analysis indicates that the
current passenger  car fleet has the potential of attaining more
than 30 MPG.

     8.   Since  1975,   Domestic   trucks  and  Asian  cars  have
experienced the major growth  in market share  at the  expense  of
Domestic cars.

     9.   Since 1975,  Domestic  trucks have increased their relative
share of the fuel consumed by the light-duty fleet from one-fifth
to  one-third  of  the  total.   Asian  cars  have quadrupled their
relative  fuel  consumption, now  accounting for one-fifth  of the
total.  Domestic cars have shown the greatest reduction in actual
fuel consumption.

Note : Classification of a vehicle as Domestic, European or Asian is based on the
authors' judgement of where the majority of the engine and emission control system
design and development work was done.  It is meant to be a tracking system for
technical parameters related to engine and emission control technology and is not a
replacement for the Domestic/Import classification used in implementing fuel economy
standards legislation.
