The 2020 Genesis G70 RWD with the 3.3L twin-turbo V6 gets 20 MPG combined. It’s not a hybrid. This G70 variant is for a specific buyer, one who wants engaging performance and a luxurious experience more than high fuel efficiency. They accept the MPG rating as the cost for the powerful engine and rear-wheel-drive dynamics that define this sport sedan.

City and highway performance

The official EPA ratings are 17 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine idles or is under low load, which is less efficient for a V6. The 26 MPG highway rating is better, suggesting the engine is in a more efficient cruising mode.

During highway driving, the G70 covers ground easily, and the smooth-shifting 8-speed automatic transmission keeps the engine at its best performance. Hard acceleration, even at highway speeds, will lower that fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Genesis G70 RWD 3.3L is $2,900. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway. The calculation the national average fuel price at the time of the EPA’s testing. Your actual fuel costs will depend on your driving, local fuel prices, and how much you drive each year.

However, $2,900 is a benchmark against other vehicles in its class, giving buyers an idea of the annual budget needed to keep the G70 fueled.

Real-world expectations

While the EPA estimates are a baseline, real-world MPG often differs. Drivers who enjoy the G70’s performance and its powerful acceleration will likely see numbers closer to the 17 MPG city rating, even on mixed driving. Those who want to conserve fuel and drive mostly on the highway might beat the 26 MPG figure. Driving style is important.

The “Sport” mode enhances throttle response and shift points but lowers fuel efficiency. Careful of “Comfort” or “Eco” mode is essential for higher MPG.

How it compares

The G70’s fuel economy is in the middle of its class. A BMW 340i gets a combined 25 MPG with its turbocharged inline-six, which is better. The Audi S4 gets 24 MPG combined. These German rivals have fuel-saving engine designs that give them an advantage. The Infiniti Q50 Red Sport 400, with its twin-turbo V6, gets the same 20 MPG combined rating as the G70, showing that horsepower costs more.

For buyers deciding between the Genesis and its rivals, G70 MPG across all years to help a buyer commit comfortably.

Tips to maximize efficiency

Use the G70’s drive modes. “Eco” mode alters throttle response and shift patterns, prioritizing fuel efficiency. It might feel less fun, but using “Eco” mode during commutes can improve MPG.

Check tire pressure. Make sure tires are at the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which hurts fuel economy. A simple check can make a difference.

Watch traffic flow. Avoiding fast acceleration and braking improves safety and fuel efficiency. By looking ahead and keeping a consistent speed, you can lower fuel use. This is helpful in cities.

Limit idling. Modern engines don’t need long warm-up periods. Idling wastes fuel. If you’re stopped for more than a minute, turn off the engine in order to be more efficient. This is important in colder areas where drivers might idle the car to warm up the cabin.

Consider an AWD model. All-wheel drive versions of the Genesis G70 offer higher fuel economy and add to the price. Drivers who like rear-wheel-drive may also like the savings that come with it. For others, all Genesis fuel economy data might change their initial direction.
