SUMMARY
Harmonic mean fuel economies, in miles per gallon, were computed
for nine carline classes which were common to the California Title 13 Data
Base and the U.S. Environmental Protection Agency (EPA) Certification Test
Data Base for 1975 and 1976 model years. The following parameters were
used to define a carline class: model year, inertia weight, cubic inch dis-
placement (CID), number of carburetor barrels, and transmission type. A
class was considered to be acceptable for analysis if it contained at least
three cars.
Both urban and high-way fuel economies determined from the California
Title 13 data were found to be consistently lower (urban: 5 to 19%; highway:
6 to 23%) than corresponding fuel economies determined from the EPA certi-
fication data. However, the statistical significance of this result could not be
assessed since the test for statistically significant differences is an asymp-
totic test requiring a larger number of cars per class than were available for
analysis in this study.

SECTION 1
INTRODUCTION
The objective of this study was to compare fuel economies from three
sources: (1) The California Title 13 Data Base Tests, (2) The U.S. Environ-
mental Protection Agency (EPA) In-Use Compliance Test program, and (3) The
EPA Certification Test Data Base.
The California Air Resources Board (CARB) testing of production
vehicles, authorized under Title 13 of the California Administrative Code, has
as its objective the emission testing of new production vehicles, with primary
attention given to those engine families which just barely meet the California
emission requirements during the EPA certification tests. Mileage is accu-
mulated on these vehicles prior to testing over an approved durability driving
schedule. The CARB permits each manufacturer to specify the mileage ac-
cumulation it considers necessary to overcome the "green-engine" effect from
an emissions point of view. Typical mileage accumulation varies from 20 to
120 miles compared to the 4000 miles accumulated on the prototype certifica-
tion test vehicles. The CARB tests about 80 engine families per year.
The In-Use Compliance Test program is conducted by the EPA to
monitor the emissions performance of production vehicles as tested after the
cars are in operation. This data base consisted of 4950 vehicles covering the
1972 through 1974 model years.
The EPA Certification Test Data Base incorporates the fuel economy
data for 1975 and 1976 model year vehicles as determined from the EPA emis-
sions certification test results. This data base includes 759 vehicles for the
1975/1976 model years. Of this total, 277 vehicles were equipped to meet the
California emission standards. The remainder -were equipped to meet the
Federal emission standards.
Data from the first source did not exist in a form suitable for analysis
at the beginning of the study. However, an appropriate data base was developed
1-1
-------
by hand-transcribing data from test results kept on file at the GARB office in
El Monte to keypunch coding forms. A card deck consisting of data on 271
cars for model years 1974 through 1976 was then generated from these forms.
Data from the other two sources were supplied by the EPA Project Officer on
magnetic tape.
Many factors affect fuel economy. Those which were singled out for
this study are as follows: inertia weight, cubic inch displacement (CID),
number of barrels in the carburetor (or fuel injection), and transmission type
(manual versus automatic). These parameters were used to define an indi-
vidual carline class. Other parameters, such as axle ratio, number of gears
in the transmission, and whether the car is air conditioned, also may have an
important effect on fuel economy. However, when additional parameters are
used to define a carline class with a relatively small data base, it becomes
increasingly difficult to find enough cars which have these parameters in com-
mon so that meaningful mean fuel economies can be determined and compared,
statistically, with other mean values. In order to assure that the data bases
could be compared on a carline basis, three cars per class were considered
to be the minimum acceptable number- The dispersion in fuel economy was
generally small enough in these classes that mean values could be used to
characterize a class. Since the test for differences between harmonic mean
values adopted by EPA in the FY 72 Automobile Exhaust Emission Surveillance -
Analysis Program (EPA-460/2 -74-001, Appendix III) is an asymptotic test,
it is not strictly applicable to classes this small in size. However, the test
statistics for comparing mean fuel economies (Appendix II) were computed
and are tabulated in Section 3 of this report.
The emission control equipment used by various manufacturers, in
general, also affects fuel economy. Consequently, cars intended for operation
in California were distinguished from those designed for the other 49 states in
defining a carline class. Also, since this equipment may change from one year
to the next because of changing emission standards, the model year was used
to define a carline class.
1-2
-------
The data which were available for this study, organized according to
model year and California versus the other 49 states, are shown in Table 1-1.
It is clear from this table that, given these data, comparisons between data
bases can only be made for California cars in model years 1974 through 1976.
However, it was found that the comparisons were further restricted by the
fact that there was an insufficient number of 1974 model year cars in the EPA
In-Use Compliance Test Data Base to compare with corresponding cars in the
California Title 13 Data Base. In the In-Use Compliance Test Data Base, the
date of purchase was used to determine the model year, while the test site
was used to determine the California cars. A carline class could not be identi-
fied which contained at least three cars purchased after September 1, 1973
and tested in Los Angeles. Consequently, it was not possible to use the EPA
in-use compliance data in this study. As a result, only comparisons between
the EPA Certification Test Data Base and California Title 13 Data Base for
model years 1975 and 1976 were made.

SECTION 2
DATA ACQUISITION AND ANALYSIS
The California Title 13 Data Base was constructed from data acquired
from the GARB, El Monte, California. A listing and description of this data
base is given in Appendix I. Three miles -per -gallon (mpg) values (from re-
peat tests) were recorded for each car. Arithmetic mean values were used
to represent individual car fuel economies. For all carline classes which
were common to this data base and the EPA Certification Test Data Base, the
mpg values corresponded to the 1975 urban test procedure. Highway values
were obtained by the use of the factors supplied by the EPA Project Officer
and are summarized in Table 2-1. Composite values were obtained from the
following formula:
"^composite = (0 . 55/mpg^J + (0. 45/mpghighway)
(The above formula and factors were used only in conjunction with the California
Title 13 data since highway and composite fuel economies were supplied directly
in the EPA Certification Test Data Base.)
As indicated in Section 1 of this report, four design parameters were
used to characterize an individual carline class: inertia weight, cubic inch
displacement (CID), number of barrels in the carburetor (or fuel injection),
and transmission type (automatic or manual). Those cars whose inertia
weights differed by a few pounds or CID by a few cubic inches were grouped ir
the same class. For example, cars with inertia weights of 5501 Ib were
grouped together with cars whose inertia weights were reported as 5500 Ib.
Similarly, cars with a CID of 302, 304, or 305 were grouped together in the
same class. With respect to the nine classes considered in this study, the only
relevant grouping parameter is the CID; e. g. , one California Title 13 class
2-1
-------
consists of two Novas (CID = 305), a Camaro (CID = 305), and three Hornet
wagons (CID = 305). This class was compared with an EPA certification class
consisting of three Monarchs (CID = 302)(Section 3, Table 3-2).

SECTION 3
RESULTS
The nine classes of cars -which were identified as common to both the
California Title 13 Data Base and the EPA Certification Test Data Base are
listed in Table 3-1. The individual models for each class are given in
Table 3-2.
Harmonic mean fuel economies for each of the classes are listed in
Tables 3-3 through 3-5. The test statistic (Appendix II) listed in these tables
can ordinarily be used to determine whether the differences in fuel economies
indicated in these tables are statistically significant at a given significance
level. For example, if the value of this test statistic exceeds 3.84146 then
the hypothesis that the mean fuel economies are the same is rejected at a
0.05 significance level. (The formulas which were used to compute the har-
monic mean fuel economies and the test statistics are given in Appendix II.)
Since this is an asymptotic test, it is not strictly applicable to the small classes
considered in this study. The values given in these tables should therefore
be treated with caution. It is apparent, however, from Tables 3-3 through
3-5 that the harmonic mean fuel economies based on the California Title 13
data are consistently lower than those based on the EPA certification data.
These values vary from 5 to 19% lower for urban driving and from 6 to 23%
lower for highway driving.
These results should be considered preliminary in nature since only
a limited number of cars were analyzed in this study. However, the differ-
ence in fuel economy between these data sources can be at least partially ex-
plained by the "green-engine" effect. As indicated in Section 1, typical mile-
age accumulation for the cars tested by the GARB varied between 20 and 120
miles compared to the 4000 miles accumulated on the EPA prototype certifi-
cation test vehicles.
3-1
-------
It was the original intent of this study to compare data bases not only
on a carline basis, but also by manufacturer and fleet. This was not possible
because of the limited number of carline classes and models per class which
were available for analysis. For example, there were only two Pintos and
two Granadas representing Ford in the California Title 13 Data Base in car-
line classes which were common to the EPA Certification Test Data Base.
These four cars cannot realistically be used to represent the Ford Motor
Company.
Even though projected sales data were available by model, it was
not used to compute sales-weighted harmonic mean fuel economies for carline
classes. In addition to relating mean fuel economies to sales, sales weight-
ing is used to correct for differences in model (or class) mix, and it is clear
from Table 3-2 that rarely are the same models being compared in the two
data bases. Also, in many cases, only a single car represents a given model.

APPENDIX I
CALIFORNIA TITLE 13 DATA BASE
A listing of the California Title 13 Data Base is given in Table 1-1.
Each line of information corresponds to a different car- The format of these
data is given in Table 1-2 with additional explanations of the coded information
in Table 1-3. In some instances, the engine family designation involved more
characters than -were provided for in the standard format. When this occurred,
a code for the engine family was put into columns 76 through 79. That code
is interpreted in Table 1-4. The occasional "X" which appears in column 80
means that at least one inconsistency in the data was recorded on the original
test forms.

16. ABSTRACT
Harmonic mean fuel economies, in miles per gallon, were computed for nine
carline classes which were common to the California Title 13 Data Base and the
U. S. Environmental Protection Agency (EPA) Certification Test Data Base for
1975 and 1976 model years. The parameters used to define a carline class were:
model year, inertia weight, cubic inch displacement, number of carburetor
barrels, and transmission type.
Both urban and highway fuel economies determined from the California Title 13
data were found to be consistently lower (urban: 5 to 19%; highway 6 to 23%) than
corresponding fuel economies determined from the EPA certification data. These
differences may be at least partially explained by the typical mileage accumulation
of 20 to 120 miles for the California tested cars compared to the 4, 000 miles
accumulated on the EPA prototype certification test vehicles.
