The 2016 Lexus GS F gets 19 MPG combined. This number quickly identifies those who understand the car’s purpose. It’s not a vehicle bought for fuel efficiency. The GS F is a performance sedan, competing directly with the BMW M5 and Mercedes-AMG E63. It’s designed for drivers who want a naturally aspirated V8 engine and engaging driving over saving gas. The fuel economy is the cost for the exciting experience this Lexus offers.

City and highway performance

The EPA estimates the 2016 Lexus GS F at 16 MPG in the city and 24 MPG on the highway. The 16 MPG city reflects stop-and-go traffic, showing the 5.0L V8’s thirst when accelerating from a stop. The 24 MPG highway is more reasonable, achievable when cruising steadily. However, driving hard, which this car encourages, will quickly reduce both numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Lexus GS F at $3,050. This is based on driving 15,000 miles per year, with fuel prices at the national average when the estimate was generated, and a mix of 55% city and 45% highway driving. Individual spending will vary depending on driving style and local gas prices, but $3,050 provides a benchmark. Remember that this is a minimum. Drivers who often use the GS F’s performance will exceed this amount, and this is before considering the car’s need for premium fuel.

Real-world expectations

EPA ratings are a guide, but real-world fuel economy changes based on driving, terrain, and weather. GS F owners who drive aggressively in cities will likely see below 16 MPG. Those who drive mostly on the highway, at a slower speed, might meet or exceed 24 MPG. Understanding the GS F’s personality and driving style is important for having realistic fuel economy expectations; this isn’t a car that rewards a heavy foot with efficiency.

How it compares

The 2016 Lexus GS F’s fuel economy is normal for its class of vehicle. The 2016 BMW M5, with its turbocharged engine, is rated at 15 MPG city and 22 MPG highway. The Mercedes-AMG E63 S with 4Matic all-wheel drive gets 15 MPG City and 22 MPG Highway, so the GS F gets a small victory on the highway. A non-performance Lexus GS 200t gets 21 city / 30 highway, showing how much GS F buyers are giving up for power and performance. These comparisons show that buyers in this segment will accept lower fuel economy for better performance and driving. You can see GS MPG across all years including more economical options.

Tips to maximize efficiency

The GS F needs premium fuel for performance. While it *might* run on regular, using premium lowers the risk of engine knocking and makes sure the car runs at its best, possibly helping fuel economy.

The GS F has an 8-speed automatic transmission, use “ECO” mode when driving daily. This mode changes the throttle and shift patterns to save fuel instead of giving immediate power. “ECO” mode significantly reduces the car’s character, so use it carefully.

Avoid fast acceleration and braking. The GS F’s strong V8 is tempting, but hard starts and stops dramatically increase fuel use. Be smooth and gradual to save fuel and have fun.

Regular maintenance is important for fuel efficiency. Make sure the tires are inflated, the engine oil is clean, and the air filter is clean. Not doing these tasks can hurt fuel economy, undoing any attempts to drive efficiently.

Minimize idling. Modern engines use fuel even when stopped. Avoid idling, especially when warming up. Turn off the engine if you’ll be stopped for more than a minute or two. This can help save fuel.
