20 MPG combined. That’s the number to keep in mind when considering the 2017 Genesis G90 AWD with the 3.3L turbocharged V6. It’s not class-leading, and it’s not particularly thrifty, but the G90 prioritizes a quiet, supremely comfortable, and technologically advanced experience that rivals European cars, but at a more palatable price. Performance and refinement are priorities, and, in that context, the fuel consumption is a compromise most G90 buyers are willing to make.

City and highway performance

The EPA estimates for the 2017 Genesis G90 AWD 3.3T are 17 MPG in the city and 24 MPG on the highway. The city figure reflects the reality of moving a large sedan through stop-and-go traffic, where the weight and the need to repeatedly accelerate from a standstill affect mileage. The turbocharged V6, while surprisingly punchy and responsive, requires a decent amount of fuel to deliver its power in these conditions. On the open road, the G90 performs better. The eight-speed automatic transmission helps keep the engine in its sweet spot, and the aerodynamic shape contributes to reasonably efficient cruising. While 24 MPG on the highway isn’t outstanding, it allows for acceptable long-distance journeys without frequent refueling stops.

Annual fuel cost

The EPA estimates the annual fuel cost for operating the 2017 Genesis G90 AWD 3.3T at $2,900. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using the national average fuel price at the time of calculation. Your actual expenditure will depend on your driving habits, the type of roads you frequent, and the price of gasoline. $2,900 provides a useful benchmark for budgeting and comparison shopping when evaluating the total cost of ownership. Consumers interested in Genesis should view all Genesis fuel economy data to see how the G90 compares to other models in the lineup.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy often differs. G90 owners report figures that hover around the EPA estimates, but aggressive driving or frequent short trips can easily reduce the average. Careful driving on long highway stretches can yield results slightly above the EPA’s 24 MPG. The G90’s trip computer provides real-time and average fuel consumption data, allowing drivers to monitor their efficiency and adjust their habits. Note that the all-wheel-drive system, while enhancing traction and stability, adds weight and complexity, which affects fuel consumption.

How it compares

The fuel economy of the 2017 Genesis G90 AWD 3.3T places it within the large luxury sedan class, but not at the top. The BMW 740i xDrive, similarly equipped with a turbocharged inline-six and all-wheel drive, achieves an EPA-estimated 24 MPG combined. The Mercedes-Benz S450 4MATIC, using newer engine technology, manages around 23 MPG combined. The Lexus LS 500 AWD gets about 21 MPG combined. These minor differences matter less to the G90’s target buyer than the lower price and generous list of standard features compared to its competitors. Affordability is a factor in the G90’s appeal, and some buyers are willing to compromise a bit on MPG to save money on the purchase price. Those seeking maximum efficiency should consider the G90 MPG across all years; however, significant gains are unlikely within the G90 model range.

Tips to maximize efficiency

The first step is to adopt a smoother driving style. Avoid abrupt acceleration and braking, anticipate traffic flow, and maintain a steady speed whenever possible. The G90’s adaptive cruise control system can be helpful on highway journeys, optimizing speed and distance to minimize fuel consumption.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, which can be found on a sticker inside the driver’s side doorjamb.

Minimize unnecessary weight. Carrying extra cargo in the trunk or back seats adds to the vehicle’s overall weight, which directly impacts fuel economy. Remove any items you don’t need on a regular basis to lighten the load and improve efficiency.

Take advantage of the G90’s drive modes. The “Eco” mode optimizes engine and transmission settings for maximum fuel efficiency. While it may reduce performance, it can make a noticeable difference in MPG, especially in city driving. Use Eco mode during less demanding driving conditions.

Regular maintenance is important for good fuel economy. Keep your engine properly tuned, replace air filters as recommended, and use the manufacturer-specified engine oil. A well-maintained engine runs more efficiently and delivers better fuel consumption.
