The short answer

EPA published 5 configurations of the 2020 Nissan Altima, 5 of them with a fuel economy rating. Combined ratings run from 29 to 32 MPG. A configuration is a specific engine, drive and transmission combination, and its rating describes that combination only.

Configurations: 5
With a fuel rating: 5
Combined MPG: 29 to 32

Fuel economy, configuration by configuration

5 of the 5 configurations carry an EPA rating. City, highway and combined are the agency's own test figures, and the annual fuel cost is its own estimate at its own assumed mileage and fuel price.

EPA and DOE ratings for the 2020 Nissan Altima. An electric configuration is rated in MPGe, which is a conversion of electricity into a gallon-equivalent and compares consumption rather than cost.

Configuration	Fuel	City	Highway	Combined	Annual fuel cost
2.5L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	Regular Gasoline	28	39	32	$1,900
2.5L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	Regular Gasoline	27	37	31	$2,000
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	Regular Gasoline	26	35	30	$2,050
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	Regular Gasoline	26	34	29	$2,100
2.0L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	Regular Gasoline	25	34	29	$2,100

What is under each of them.

Engine, drive and transmission as EPA recorded them. A blank is a field the agency did not populate, which on an electric car is most of this table.

EPA vehicle records for this model year. Displacement is in litres and the transmission code is EPA's own.

Configuration	EPA class	Engine	Drive	Transmission

2.5L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	Midsize Cars	2.5L, 4-cyl	Front-Wheel Drive	Automatic (variable gear ratios)
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	Midsize Cars	2.5L, 4-cyl	All-Wheel Drive	Automatic (variable gear ratios)
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	Midsize Cars	2.5L, 4-cyl	All-Wheel Drive	Automatic (variable gear ratios)
2.0L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	Midsize Cars	2L, 4-cyl, turbo	Front-Wheel Drive	Automatic (variable gear ratios)

Tailpipe CO2 and EPA's own scores

EPA scores fuel economy and greenhouse gas out of 10, where 10 is best. Tailpipe CO2 is grams per mile, and it is tailpipe only: it does not count the emissions of generating the electricity an electric car runs on, which is why every EV on this table reads zero.

EPA greenhouse gas and fuel economy scores, and tailpipe CO2 in grams per mile.

Configuration	CO2 g/mi	GHG score	Fuel economy score
2.5L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	278	7 / 10	7 / 10
2.5L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	288	7 / 10	7 / 10
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	300	7 / 10	7 / 10
2.5L, 4-cyl, Automatic (variable gear ratios), All-Wheel Drive	307	6 / 10	6 / 10
2.0L, 4-cyl, Automatic (variable gear ratios), Front-Wheel Drive	311	6 / 10	6 / 10

About these figures

EPA and DOE fuel economy ratings (FuelEconomy.gov). Unaveraged: each EPA configuration is its own row, because a trim's rating is not the model's. FuelEconomy.gov asks that its data be attributed to EPA and DOE and not presented as an official EPA product. This page is our arrangement of it, not theirs.

New York State DMV registration file, August 17, 2026 snapshot of the five New York City counties. Model names come from NHTSA's federal VIN decoder. A registration is a record in a state database, not a car on the road. How we counted. The borough is where the registrant receives mail rather than where the car is driven.

Fuel economy: EPA and DOE ratings published at FuelEconomy.gov, unaveraged, so each configuration is its own row. Recalls and complaints: NHTSA Office of Defects Investigation, the agency's own wording, as ingested August 17, 2026. Complaints are reports members of the public filed, not confirmed defects. The NYC registration study is the analysis these counts sit on top of.
