24 MPG combined isn’t going to set any records, but it’s a reasonable compromise for the 2017 Lexus GS 200t F Sport. Nobody buys this car for ultimate fuel efficiency; they buy it for the engaging driving experience, aggressive styling, and the renowned Lexus reliability. Accepting mid-20s MPG is simply the price of admission for a sharp-handling, turbocharged sport sedan with a luxurious interior.

City and highway performance

The EPA estimates for the GS 200t F Sport are 21 MPG in the city and 30 MPG on the highway. The city number reflects the reality of stop-and-go traffic, where the 2.0L turbocharged engine works harder and the automatic transmission cycles through gears frequently.

The highway figure is more palatable, showcasing the engine’s ability to cruise efficiently at speed. 30 MPG on the open road is a respectable number, especially when considering the car’s sporty intentions and standard features that add weight.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2017 Lexus GS 200t F Sport will be around $2,400. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices.

Your individual fuel costs will vary depending on how you drive, where you drive, and fuel prices in your area. Someone who primarily commutes in heavy traffic will likely see a higher annual cost, while someone who takes mostly highway trips might come in a bit lower. $2,400 is a benchmark for evaluating the overall cost of ownership.

Real-world expectations

While EPA estimates provide a useful baseline, real-world fuel economy often differs. The GS 200t F Sport, with its responsive turbo engine and sporty tuning, encourages spirited driving. Drivers who enjoy exploiting the engine’s power and the car’s handling prowess might see fuel economy dip below the EPA estimates.

Conversely, those who adopt a more moderate driving style and prioritize fuel conservation can often meet or even exceed the EPA numbers. The F Sport trim prioritizes driving enjoyment, so expecting to consistently achieve the published MPG requires conscious effort.

How it compares

The Lexus GS 200t F Sport competes in a crowded segment of luxury sport sedans. The BMW 330i achieves a slightly better EPA combined rating of 28 MPG, appealing to buyers prioritizing fuel efficiency without sacrificing driving dynamics. The Audi A4 2.0T Quattro also offers a similar advantage, with EPA estimates hovering around 27 MPG combined.

The Cadillac ATS 2.0T, when equipped with rear-wheel drive, posts slightly lower numbers around 25 MPG combined, making it a less fuel-conscious choice. The Mercedes-Benz C300, a perennial rival, splits the difference, often landing around 26 MPG combined.

Shoppers comparing cost of ownership and overall economy can find all Lexus fuel economy data useful. Comparing the GS’s numbers to the GS MPG across all years also informs the shopping process, letting the buyer see if newer models have brought better efficiency.

Tips to maximize efficiency

The 2.0L turbocharged engine in the GS 200t F Sport responds well to smooth acceleration. Avoid aggressive starts and hard braking to conserve fuel. Gentle throttle inputs allow the turbocharger to spool up efficiently, providing adequate power without excessive fuel consumption.

Anticipating traffic flow and maintaining a steady speed whenever possible will also yield noticeable improvements.

Pay attention to tire pressure. Maintaining the correct tire pressure, as listed on the doorjamb sticker, reduces rolling resistance and improves fuel economy. Under-inflated tires create more friction, forcing the engine to work harder and burning more fuel.

Regularly checking and adjusting tire pressure is a simple way to maximize efficiency and extend tire life.

Use the Lexus Drive Mode Select system wisely. The GS 200t F Sport offers different driving modes, including an “Eco” mode. Engaging Eco mode adjusts the throttle response and transmission mapping to prioritize fuel efficiency.

While it may slightly reduce performance, it can make a significant difference in fuel consumption, especially during city driving or situations where performance is not critical.

Minimize idling. Excessive idling consumes fuel without covering any distance. If you’re stopped for more than a minute or two, consider turning off the engine. Modern engines are designed to restart quickly and efficiently, so the fuel saved by avoiding prolonged idling can add up over time.

Keep up with scheduled maintenance. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures that the engine is running at peak efficiency. A well-maintained engine burns fuel more cleanly and effectively, reducing emissions and maximizing fuel economy.

Neglecting maintenance can lead to decreased performance and increased fuel consumption.
