The 2018 Genesis G80 RWD with the 3.3L V6 engine gets 20 MPG combined. This G80 isn’t for those chasing maximum efficiency. Instead, it’s for buyers who prioritize a smooth, powerful engine, a comfortable ride, and a luxury experience at a price that’s less than its German rivals. These buyers accept the fuel economy as a trade-off for the overall value. They want a refined sedan that delivers effortless performance without seeming stuffy or costing what those in the segment usually do.

City and highway performance

The EPA estimates the 2018 Genesis G80 RWD 3.3L V6 gets 17 MPG in the city and 25 MPG on the highway. The city number shows the demands on the engine during stop-and-go traffic, where there are no fuel-saving benefits like on the highway. The 25 MPG highway figure shows the engine’s ability to deliver respectable efficiency when operating at a consistent speed, helped by the smooth-shifting eight-speed automatic transmission. The transmission is programmed for efficiency, readily seeking higher gears to keep engine RPMs low during steady-state highway driving. Managing acceleration is key; a gentle foot on the accelerator pedal directly improves real-world figures on the open road.

Annual fuel cost

The EPA calculates that the annual fuel cost for the 2018 Genesis G80 RWD 3.3L V6 is approximately $2,900. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the EPA’s estimate of national average fuel prices. Actual costs may vary depending on individual driving habits and fluctuating fuel prices. Drivers who do a significantly higher proportion of city driving, or those who accelerate more, should expect to exceed this amount. Those who primarily use the G80 for longer highway trips may see a slightly lower annual fuel bill. This figure puts it in perspective alongside other luxury vehicles with similar power outputs.

Real-world expectations

The EPA provides a standardized estimate, but real-world fuel economy often differs based on driving style, traffic conditions, and terrain. Owners of the 2018 Genesis G80 RWD 3.3L V6 often report figures hovering around the EPA’s combined estimate of 20 MPG, but this requires a conscious effort to drive efficiently. More spirited driving, shorter trips, and frequent use of the G80’s ample power can easily reduce fuel economy to the mid-teens. Those who prioritize fuel efficiency during longer highway drives might see figures closer to, or even slightly exceeding, the EPA’s 25 MPG highway estimate. Always check G80 MPG across all years to better understand how factors have helped MPG figures improve.

How it compares

The 2018 Genesis G80’s fuel economy places it in the middle of its luxury sedan competitors. For example, the BMW 540i xDrive, with its turbocharged inline-six and all-wheel drive, achieves an EPA-estimated 23 MPG combined. The Mercedes-Benz E300, with its smaller turbocharged four-cylinder engine, manages a slightly better 25 MPG combined. However, those vehicles cost more. A Lexus GS 350 RWD nets 23 combined MPG. The Genesis G80 buyer isn’t necessarily cross-shopping with these vehicles solely based on fuel economy; other factors like price, features, and styling play a significant role. This buyer is accepting a slightly lower fuel economy for the G80’s unique blend of luxury, performance, and value. See all Genesis fuel economy data for more comparison data.

Tips to maximize efficiency

The Genesis G80’s eight-speed automatic transmission is programmed to shift early and often to maximize fuel economy, so allow it to do its job. Avoid aggressive acceleration and opt for a gentler driving style. Let the engine’s torque do the work, especially in city driving, avoiding unnecessary high RPMs.

Regular maintenance is critical for optimal fuel economy. Ensure that your G80’s tires are properly inflated to the recommended pressure outlined on the driver’s side door jamb. Underinflated tires increase rolling resistance, which directly impacts fuel consumption. Keep up with scheduled oil changes and air filter replacements too.

Minimize unnecessary weight. Carrying extra cargo in the trunk or backseat adds weight to the vehicle, forcing the engine to work harder and burning more fuel. Remove any items that you don’t need on a regular basis. Each pound adds up, especially during city driving and stop and go traffic.

Avoid using the G80’s Sport mode unless you specifically need the extra performance. The Sport mode alters the transmission’s shift points and throttle response, prioritizing performance over fuel efficiency. Leave the car in Comfort mode for most driving situations to optimize fuel economy.

Plan your routes strategically. Especially during peak traffic hours, consider alternative routes that minimize stop-and-go driving and idling. Even slightly longer routes with fewer traffic lights can improve your overall fuel economy, especially if you’re trying to achieve the EPA’s highway fuel economy figures.
