The 2023 Genesis G70 RWD with the 3.3L twin-turbo V6 gets 21 MPG combined. That number puts it with other performance-oriented compact luxury sedans. This car prioritizes a thrilling driving experience and design over outright fuel savings. The G70 3.3T aims to deliver a blend of power and luxury, and fuel economy is important, even if it is secondary.

City and highway performance

The EPA estimates 18 MPG in the city and 27 MPG on the highway. The city figure reflects the engine’s responsiveness in stop-and-go traffic, where the twin-turbo V6 delivers immediate power, but uses more fuel. The highway MPG is better. It uses the eight-speed automatic transmission’s ability to settle into higher gears and cruise efficiently at sustained speeds. However, even on the highway, using a lot of throttle will drop that number. The G70’s size and aerodynamic profile help, but the 3.3L V6 under the hood is designed for strong acceleration, not fuel sipping on long journeys. Know that if your driving style is aggressive, you need to lower your expectations about getting even EPA highway numbers.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2023 Genesis G70 RWD 3.3L. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on how much you drive, what type of driving you do, and where you live, as fuel prices differ across the country. While it is just an estimate, it provides a useful comparison for the G70’s running costs compared to other vehicles.

Real-world expectations

The EPA provides an estimate, but real-world fuel economy can change a lot. Driving style, traffic, tire pressure, and even the weather can change your MPG. Being aggressive with the accelerator, hard braking, and extended idling will all hurt fuel efficiency. The G70’s eagerness to rev and the exhaust tempt drivers to push the engine, which can result in lower-than-expected MPG. Depending on your commute, you may never see 27 MPG on the highway because stop and start traffic, merging, and overall traffic will drag down the EPA numbers.

How it compares

Compared to its rivals, the G70 3.3T’s fuel economy is competitive. The BMW 340i, with its turbocharged inline-six, achieves a slightly better 26 MPG combined. The Mercedes-Benz C43 AMG posts similar figures to the Genesis G70. The Acura TLX Type S, with its turbocharged V6, lands around 21 MPG combined, the same as the G70. Buyers often cross-shop these models, so these comparisons matter. While fuel efficiency might not be the only thing to consider, it’s a data point that influences the overall ownership cost. For better fuel efficiency in a luxury sedan, look at the G70 2.0T with its turbocharged four-cylinder, or even hybrid options from Lexus or Volvo.

Tips to maximize efficiency

Use the G70’s Eco drive mode. It tones down the engine’s responsiveness, and it optimizes the powertrain for fuel efficiency without sacrificing too much performance. “Normal” drive mode is not tuned for high fuel economy. Eco will give you the best chance to achieve it.

Monitor your tire pressure. Underinflated tires increase rolling resistance, which causes decreased fuel economy. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure and check them at least once a month, and before any long road trips. Don’t just rely on the tire pressure monitoring system. Check the pressure with a gauge.

Minimize idling time. If you are waiting for someone, turn off the engine instead of letting it idle, especially in cold weather. Modern engines warm up quickly, and extended idling is a waste of fuel. The G70’s start/stop system will automatically turn off the engine at stoplights, and this feature is a worthwhile choice in stop-and-go traffic.

Drive smoothly and avoid aggressive acceleration. The G70’s twin-turbo V6 is tempting to use, but a gentler driving style will improve fuel economy. Anticipate traffic flow, maintain a consistent speed, and avoid quick acceleration and braking. Think ahead to maximize fuel economy.

When possible, adjust your route to avoid peak traffic. Stop-and-go traffic lowers fuel economy. Try planning to leave for work or errands at off-peak times to avoid rush-hour congestion. Taking a longer route may save time and fuel if speeds are less interrupted.
