42 MPG combined is the headline for the 2018 Chevrolet Volt 1.5L 4-cyl, and that number says a lot about this car’s mission. This isn’t just about saving money on gas; it’s about using less gas for drivers with relatively short commutes who still want the flexibility of a gasoline engine for longer trips. The buyers of this Volt model year are often motivated by lower fuel costs and a desire to reduce their carbon footprint without sacrificing practicality.

City and highway performance

The Volt’s split between city and highway fuel economy is remarkably consistent: 43 MPG in the city and 42 MPG on the highway. This near-identical rating shows the efficiency of the Volt’s electric drivetrain in a variety of driving conditions. In city driving, the electric motor does most of the work, allowing the gasoline engine to remain off for extended periods. Even on the highway, the Volt’s powertrain is optimized to minimize gasoline consumption, switching between electric and gasoline power as needed to maintain optimal efficiency. This blend of electric and gasoline propulsion delivers consistent fuel economy regardless of where you drive.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Chevrolet Volt 1.5L 4-cyl is $1,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. This figure shows the potential for savings compared to traditional gasoline-powered cars. Individual fuel costs may vary depending on driving habits and local fuel prices.

Real-world expectations

While the EPA estimates provide a good baseline, real-world fuel economy can vary. Volt owners often exceed the EPA estimates, especially those with shorter commutes and access to charging. Regular charging provides the best MPG. Aggressive driving and prolonged highway speeds will decrease fuel economy, but even in these scenarios, the Volt is likely to deliver better fuel economy than a conventional gasoline car. The key is to maximize electric driving by charging regularly and driving efficiently.

How it compares

The 2018 Chevrolet Volt’s fuel economy is among the leaders in its segment. The Toyota Prius Prime, another plug-in hybrid, achieves 54 MPG combined when operating in hybrid (gasoline and electric) mode. Many plug-in hybrids, like the Prius Prime, have a limited all-electric range before the gasoline engine engages. The Hyundai Ioniq Plug-In Hybrid is another contender, delivering around 52 MPG combined in hybrid mode. While the Volt’s numbers are relatively close to these plug-in hybrid competitors, the Volt is valuable because of its electric-first design. For drivers who want to maximize electric range and use gasoline only when necessary, the Volt stands out. See all Chevrolet fuel economy data for a wider look at the brand’s efficiency.

Tips to maximize efficiency

Use regenerative braking whenever possible. The Volt’s regenerative braking system captures energy during deceleration and braking, which helps recharge the battery and extend electric range. Gently lift off the accelerator pedal to maximize regenerative braking without using the friction brakes.

Precondition the cabin while the car is plugged in. Use the Volt’s remote start feature or the MyChevrolet app to warm or cool the cabin while the car is still connected to the charger. This preconditioning uses electricity from the grid, conserving battery power for driving and improving overall fuel economy.

Drive in “L” (Low) gear in city traffic. Selecting “L” gear increases the level of regenerative braking, allowing you to recapture more energy and reduce wear on the brake pads. It also provides better control in stop-and-go traffic, making it easier to drive efficiently.

Minimize aggressive acceleration. Quick acceleration burns more gasoline in hybrid vehicles. Accelerate smoothly and gradually to stay in electric mode whenever possible and to minimize gasoline consumption.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure level, which can be found on a sticker on the driver’s side doorjamb.
