Addendum: Nissan and Mitsubishi Data
This addendum to the 2018 Automotive Trends report provides additional data on Nissan
and Mitsubishi. EPA is publishing this additional content to provide data that aligns with a
determination by the National Highway Traffic Safety Administration (NHTSA) that the two
companies be treated as separate entities for compliance.
In late 2016, Nissan purchased 34% of Mitsubishi, thus bringing Mitsubishi into the
Renault-Nissan-Mitsubishi Alliance. The change in the relationship between Nissan and
Mitsubishi triggered a review by NHTSA to determine if the two manufacturers should be
treated as one entity for the purposes of compliance with the CAFE program, with EPA
following NHTSA's determination for the corresponding light-duty GHG program. NHTSA's
initial input to EPA was that the two companies would be combined for regulatory
purposes, beginning with model year 2017. However, after additional consideration, NHTSA
determined that Nissan and Mitsubishi would remain independent for CAFE and, thus, the
GHG program.
When EPA released the 2018 EPA Automotive Trends Report, Nissan and Mitsubishi data
were combined and reported as "Nissan-Mitsubishi" throughout most of the report, with
the acknowledgement that the review process was not yet complete. At the time, EPA
committed to provide an update if, in fact, the two companies were not combined for
regulatory purposes. This addendum provides separated Nissan and Mitsubishi data, in
accordance with EPA's commitment to provide the most accurate data that reflect the
current regulatory configuration of the industry. This addendum does not include any
updates to the underlying data presented in the 2018 Trends report and is limited to
Nissan and Mitsubishi data. Both estimated real-world data and compliance data are
presented below, as in the full report. For an explanation of these terms or more
information about the data, please see the full report.
Addendum-1

-------
A. Estimated Real World Fuel Economy and CO2
Emissions
Nissan has a much larger presence than Mitsubishi in the U.S. light duty vehicle market. For
model year 2017, Nissan produced 1,688,689 vehicles, compared to 123,495 vehicles
produced by Mitsubishi. The vehicles produced by Mitsubishi are, on average, smaller and
more fuel efficient than those of Nissan, as show in the updated Tables 2.2 and 3.3. The
values in these two tables show estimated real-world fuel economy and CO2 emission
data. The combined Nissan-Mitsubishi values originally reported are shown for comparison
purposes only.
Throughout the Trends report, many tables and figures only include manufacturers that
produced over 150,000 vehicles for sale in the united states. Mitsubishi does not meet this
threshold. However, we have chosen to provide Mitsubishi-specific data here to illustrate
the impact of separating Nissan and Mitsubishi.

B. Manufacturer GHG Compliance
In accordance with NHTSA's determination, Nissan and Mitsubishi will remain as separate
entities for compliance with the CAFE and GHG programs. Both manufacturers ended the
2017 model year with a positive credit balance and are thus in compliance with the model
year 2017 and all previous years of the GHG program. The three tables below summarize
the compliance data for Nissan and Mitsubishi beginning with model year 2017 (Tables 5.5
and 5.11), and then show the manufacturers' overall credit status (Table 5.17). The
combined Nissan-Mitsubishi values originally reported are shown for comparison purposes
only.
