The 2021 Genesis G70 RWD 2.0L’s 25 MPG combined fuel economy won’t win any efficiency awards, but it accurately reflects the car’s mission: a refined, sporty sedan prioritizing driving enjoyment over outright frugality. This isn’t a car for hypermilers, but for those who appreciate a well-balanced chassis, responsive engine, and a touch of luxury without breaking the bank.

City and highway performance

The EPA estimates the G70 2.0T RWD at 22 MPG in the city and 30 MPG on the highway. These figures are reasonable and reflect the engine’s need to work a bit harder in stop-and-go traffic compared to cruising at a steady speed. The eight-speed automatic transmission does its best to keep the engine in its sweet spot, but the 2.0L turbo still requires some revs to deliver its power, impacting fuel consumption in urban environments. On the open road, the G70 settles into a comfortable and relatively efficient rhythm, allowing drivers to take advantage of that 30 MPG rating.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Genesis G70 RWD 2.0L at $2,300. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel price. While your individual fuel costs will vary depending on your driving habits and local fuel prices, this $2,300 estimate provides a useful benchmark for comparing the G70’s running costs against other vehicles. You can review G70 MPG across all years to compare to other model year estimates.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy often differs. You can expect to see numbers slightly below the EPA estimates if you frequently drive aggressively or spend most of your time in heavy traffic. However, consistently smooth driving on the highway could yield slightly better results. Regular maintenance, including properly inflated tires and timely oil changes, also plays a role in maximizing fuel efficiency, as with any vehicle.

How it compares

The G70’s fuel economy stacks up reasonably well against its direct competitors, but there are trade-offs. The BMW 330i, for example, also achieves a combined 25 MPG with its 2.0L turbo engine, mirroring the G70’s figure. The Audi A4 40 TFSI, rated at 29 MPG combined, ekes out a fuel efficiency advantage, though some might find its driving experience less engaging. The Mercedes-Benz C300, rated at 28 MPG combined, offers a blend of luxury and efficiency. Buyers in this segment must weigh their priorities: driving dynamics, luxury features, and fuel economy all play an important role in the final decision.

Tips to maximize efficiency

Use the G70’s drive modes. Selecting “Eco” mode will remap the throttle response and shift patterns to prioritize fuel efficiency, albeit at the expense of outright performance. Use this mode when cruising on the highway or in low-demand driving situations.

Avoid aggressive acceleration and braking. The G70’s turbocharged engine responds well to a gentle touch. Smooth, gradual acceleration and anticipating traffic flow to minimize braking will significantly improve fuel economy.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressures regularly and inflate them to the recommended levels indicated on the doorjamb sticker.

Minimize idling. Letting the engine idle for extended periods consumes fuel unnecessarily. If you anticipate stopping for more than a minute, it’s generally more efficient to turn off the engine. The G70’s start-stop system, if equipped, helps mitigate this issue by automatically shutting off the engine at stoplights.

Reduce weight in the vehicle. Carrying unnecessary cargo adds weight, which increases fuel consumption. Remove any items from the trunk or cabin that you don’t need for your journey to lighten the load and improve efficiency.
