32 MPG combined isn’t the most exciting number in the compact car segment. But for owners of the 2015 Chevrolet Cruze 2.0L diesel, it’s a trade-off they’ve considered. These buyers aren’t chasing the highest MPG, but value diesel torque, relaxed highway cruising, and long range. They’re willing to accept slightly lower numbers than a Toyota Prius for a driving experience that suits them. The Cruze diesel appeals to a practical buyer who appreciates the low-end power of a diesel engine and less frequent trips to the gas station, even if it doesn’t lead in overall fuel efficiency.

City and highway performance

The EPA numbers are 27 MPG in the city and an impressive 44 MPG on the highway. That highway figure is key to the Cruze diesel’s appeal. While 27 MPG in urban environments is adequate compared to other compact cars, the 44 MPG on the open road means genuine long-distance capability. This makes the Cruze diesel a good option for commuters who drive a lot on the highway or prefer the relaxed cruising that a diesel engine provides. The six-speed automatic transmission works well with the engine’s characteristics, helping it stay in its best range for fuel economy on the highway, while also providing smooth shifts around town. The Cruze diesel is optimized for the driving its target market does most often.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,750 for the 2015 Chevrolet Cruze 2.0L diesel. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. It’s a useful way to compare the Cruze diesel to other vehicles. It offers a clear idea of its long-term running costs. Individual fuel costs will vary depending on driving habits and location-specific fuel prices, but this $1,750 figure provides a standard for comparison. Diesel fuel prices can change more than gasoline, so watch local prices to estimate your own costs. You can also view CRUZE MPG across all years to see how this compares against earlier models.

Real-world expectations

While the EPA figures are a good start, real-world fuel economy can change a lot depending on driving style, traffic, and terrain. Hard acceleration, hard braking, and long idling will hurt fuel efficiency. Driving in hilly areas will usually mean lower MPG than on flat highways. However, drivers who are smooth and consistent and avoid idling can often meet or exceed the EPA estimates, especially on long highway trips. The Cruze diesel’s trip computer can help you watch fuel economy and find ways to improve.

How it compares

Compared to its gasoline versions in 2015, the Cruze diesel had better highway fuel economy, if not always combined. A 2015 Honda Civic, for example, got around 31 MPG combined and 41 MPG highway in its most efficient version. A Toyota Corolla LE Eco managed about 35 MPG combined and 42 MPG highway. The Corolla is better than the Cruze in combined MPG, but the difference isn’t huge, considering the diesel’s torque and different driving experience. For buyers who value highway efficiency and diesel power, the Cruze is still a good choice. You can compare it against all Chevrolet fuel economy data to see how the brand compares overall, too.

Tips to maximize efficiency

Regular maintenance is critical for fuel economy in any vehicle, including the Cruze diesel. Change the engine oil, air filter, and fuel filter as recommended by the manufacturer. A clean air filter helps the engine breathe easier, and fresh oil reduces friction and wear. All of these improve fuel efficiency.

Tire pressure makes a big difference to fuel economy. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure and inflate them to the recommended PSI, which is on a sticker inside the driver’s side doorjamb. Even a few PSI below the level can make a difference.

Avoid idling. Diesel engines use a lot of fuel when idling, compared to gasoline engines. If you’ll be stopped for more than a minute or two, turn off the engine. This saves fuel and reduces emissions.

Use cruise control carefully, especially on flat roads. Staying at a consistent speed helps fuel economy by reducing acceleration and deceleration. Be careful of using cruise control in hilly areas, as the system may downshift often, negating the fuel savings.

Plan your routes, avoiding traffic when possible. Stop-and-go traffic lowers fuel economy due to acceleration and braking. Choosing routes with fewer intersections and more consistent speeds can improve MPG, especially in city driving.
