The 2016 Lexus GS 350 F Sport delivers 22 MPG combined. It’s not focused on being a fuel-efficient car. This model prioritizes a responsive driving experience and luxury over saving on gas costs. The target buyer wants a comfortable and stylish sport sedan with good performance, and they accept the fuel consumption that comes with it.

City and highway performance

The GS 350 F Sport gets 19 MPG in the city because of its strong 3.5-liter V6 engine and traditional automatic transmission. Stop-and-go driving and frequent acceleration reduce gas mileage. On the open road, the Lexus performs better, achieving 27 MPG in EPA highway testing. The engine cruises comfortably at higher speeds, making it a good choice for longer trips. Aggressive driving or hilly roads will lower the highway MPG.

Annual fuel cost

The EPA estimates that you’ll spend $2,650 on fuel each year with the 2016 Lexus GS 350 F Sport. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway. The calculation assumes average national prices for regular unleaded gasoline at the time of testing. Your actual fuel costs may change based on your driving habits, local gas prices, and driving conditions.

Real-world expectations

The EPA figures are a guideline, but your actual fuel economy will likely be different. If you often drive fast or encounter heavy traffic, expect slightly lower MPG than the official ratings. If you mainly drive on the highway and accelerate gently, you might see figures closer to or slightly above the 27 MPG highway rating. Tire pressure, car maintenance, and weather affect your overall MPG.

How it compares

The 2016 Lexus GS 350 F Sport’s fuel economy is in the middle compared to competitors. The BMW 535i (20 MPG combined) offers similar performance but slightly worse fuel efficiency. The Mercedes-Benz E400 from the same year gets around 23 MPG combined. The Acura TLX V6 with SH-AWD achieves a slightly better 25 MPG combined but doesn’t have the same prestige and rear-wheel-drive feel as the Lexus. Buyers probably compare these cars considering performance, luxury, and fuel costs. See all Lexus fuel economy data here. To see GS MPG across all years, check this page.

Tips to maximize efficiency

Use the Lexus’ Drive Mode Select system. The “Eco” mode focuses on fuel efficiency by changing the throttle response and transmission, for city driving and steady highway cruising.

Keep tires properly inflated. Underinflated tires increase rolling resistance, lowering fuel economy. Check your tire pressure and inflate them to the manufacturer’s recommended specs, usually on a sticker inside the driver’s side door or in the owner’s manual.

Remove extra weight from the car. Extra cargo adds weight, which requires more energy to accelerate and maintain speed. Remove unnecessary items to improve your MPG, mainly for city driving.

Accelerate smoothly and gradually. Avoid sudden bursts of speed, which use a lot of fuel. Accelerate smoothly and anticipate traffic to reduce hard braking and acceleration.
