20 MPG combined reflects a trade-off in the 2021 Genesis G70 RWD 3.3L. It’s for drivers who want the thrill of a strong twin-turbo V6 and rear-wheel drive in a compact luxury sedan. This G70 isn’t about saving every last drop of fuel, but delivering a fun driving experience that rivals BMW and Audi, while offering good value.

City and highway performance

The EPA estimates for the 2021 Genesis G70 RWD 3.3L are 17 MPG in the city and 26 MPG on the highway. The lower city figure reflects the engine’s fuel consumption in stop-and-go traffic, where the turbochargers may work harder. The highway number is more respectable and reflects the engine’s ability to cruise efficiently once up to speed. While 26 MPG isn’t class-leading, it’s fine for longer road trips and allows for comfortable distances between fill-ups. The eight-speed automatic transmission also plays a key role, offering smooth gear changes in various driving conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Genesis G70 RWD 3.3L is $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. This $2,900 is an estimate, and your actual fuel costs may vary. How and where you drive affects fuel costs, as do fluctuating fuel prices. Aggressive driving, frequent short trips, and consistently using premium fuel (recommended for best performance) will increase your yearly spending. Smooth acceleration, highway driving, and routine maintenance can help you keep closer to, or even slightly below, the EPA estimate.

Real-world expectations

The EPA provides standardized testing, but real-world fuel economy varies depending on driving habits, road conditions, and weather. Drivers who regularly push the G70’s engine can expect MPG closer to the low end of the EPA range. A more relaxed driving style may lead to better results, especially on the highway. Terrain matters, too; hilly areas will decrease fuel economy. In the end, the 2021 G70 RWD 3.3L rewards those who understand its performance and manage their expectations.

How it compares

The 2021 Genesis G70 RWD 3.3L is competitive in fuel economy, but not class-leading. A BMW 330i achieves 28 MPG combined, a significant advantage. The BMW M340i with its inline-six engine drops closer to the G70’s numbers, around 25 MPG combined. The Audi S4, another performance sedan, gets around 24 MPG combined, making the G70 look better by comparison. The Lexus IS 350 RWD achieves around 23 MPG combined. These comparisons matter because they emphasize the balance between performance and fuel efficiency. The G70 buyer may sacrifice a few MPG for the power and handling this model delivers, and wants to save money at the dealership versus the Germans.

Tips to Maximize Efficiency

Take advantage of the G70’s drive modes. “Eco” mode remaps the throttle and shift points to prioritize fuel efficiency, but performance will be affected. Consider using this mode for commutes or when conserving fuel is your goal.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, hurting fuel economy. The right tire pressure improves fuel efficiency, handling, and tire life.

Avoid hard acceleration and braking. The G70 delivers power easily, but smooth driving is more efficient. Anticipate traffic and avoid unnecessary hard acceleration or braking to save gas.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Idling consumes gas and increases emissions. The G70 doesn’t have auto stop/start for the 3.3T, so managing the engine is important.

Keep up with maintenance. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs well and efficiently. A maintained engine gives better fuel economy.
