1990 Nissan 300ZX 2x2: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 1990 Nissan 300ZX 2x2. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. The EPA rates 2 separate variants of this car (different engine, transmission, or drivetrain combinations), and you can compare them side by side in the trims table. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 1990 Nissan 300ZX 2x2. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

When the EPA tests several variants of the same nameplate (for example, a front-wheel-drive version and an all-wheel-drive version), each gets its own rating. The figures shown here are the headline variant, taken as the configuration with the best combined MPG. The trims table further down covers all 2 variants side by side.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 1990 Nissan 300ZX 2x2 compares

The 1990 Nissan 300ZX 2x2 returns 19 combined MPG. Cars in the Subcompact Cars class for the same model year average 23 MPG, which puts this car behind the class average by about 17%.

The most efficient car in the Subcompact Cars class for the 1990 model year is the Geo Metro XFI at 47 MPG. The bar chart below puts the Nissan 300ZX 2x2 alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 1990 model year (across all classes) returns 19.1 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 1990 model year is on its own page.

Trim variants rated for 1990

The EPA rates 2 separate variants of the 1990 Nissan 300ZX 2x2. The differences come from the engine size, transmission type, and drivetrain (front-wheel drive, all-wheel drive, and so on). The same nameplate can land several MPG apart depending on the configuration you actually buy.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 789.5 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Nissan 300ZX 2x2

The EPA has rated the Nissan 300ZX 2x2 across 13 model years, from 1984 Nissan 300ZX 2x2 through 1996 Nissan 300ZX 2x2. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

Combined MPG has stayed in roughly the same range across the run, hovering close to 19 MPG.

Compare against other Subcompact Cars for 1990

Specifications

The 1990 Nissan 300ZX 2x2 runs a 3-liter 6-cylinder engine paired with a automatic 4-spd, sending power through rear-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.

• Is the 1990 Nissan 300ZX 2x2 fuel efficient?

  Not particularly. The 1990 Nissan 300ZX 2x2 returns 19 combined MPG, which trails the average car in the Subcompact Cars class for the same model year by about 17%.
• What MPG does the 1990 Nissan 300ZX 2x2 get?

  The EPA rates the 1990 Nissan 300ZX 2x2 at 19 combined MPG, 17 MPG in city driving, and 22 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is.
• How much does it cost to fuel a 1990 Nissan 300ZX 2x2 per year?

  The EPA estimates an annual fuel cost of $3,650 for the 1990 Nissan 300ZX 2x2. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• Does the 1990 Nissan 300ZX 2x2 require premium gas?

  Yes. The EPA lists the 1990 Nissan 300ZX 2x2 as requiring premium gasoline. Running it on regular can reduce performance and may affect engine warranties, so it is not a recommended way to save at the pump.
