While the 2017 Lexus GS 200t’s 26 MPG combined won’t break any fuel efficiency records, it offers a good balance for a rear-wheel-drive luxury sedan designed for comfort, style, and a hint of sportiness. GS 200t buyers are usually professionals who prioritize Lexus’ reputation for reliability and refinement over extreme fuel efficiency. They desire a car with a special feel, good handling, and an image of success, making the 200t’s MPG an acceptable compromise for those priorities.

City and highway performance

The EPA estimates the GS 200t achieves 22 MPG in the city and 32 MPG on the highway. This difference reflects the car’s turbocharged engine, which performs best at consistent cruising speeds. Stop-and-go traffic requires more frequent power bursts, lowering city fuel consumption. The eight-speed automatic transmission also matters. It shifts smoothly and efficiently, but its many gears result in more shifting in urban environments, impacting fuel economy. Highway driving allows the transmission to settle into higher gears, enabling more efficient engine operation at lower RPMs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Lexus GS 200t at $2,250. This calculation assumes 15,000 miles of driving per year, a mix of city and highway conditions, and national average fuel prices. Your actual fuel expense may differ depending on your location and driving habits, because fuel prices vary regionally and fluctuate throughout the year.

Real-world expectations

EPA estimates are standardized, but real-world fuel economy varies depending on driving habits, terrain, and environment. Aggressive acceleration, hard braking, and extended idling all negatively affect the GS 200t’s MPG. Smooth, moderate driving, proper tire inflation, and regular maintenance can help you achieve numbers closer to, or even slightly above, the EPA estimates. The GS 200t is designed with a sporty feel and many owners enjoy the performance, which impacts fuel economy.

How it compares

The 2017 GS 200t’s fuel economy is competitive in its class. The BMW 530i, with its 2.0-liter turbo, gets an EPA-rated 27 MPG combined, slightly better than the GS 200t. The Mercedes-Benz E300, also with a 2.0-liter turbo, gets around 25 MPG combined, similar to the Lexus. The Acura TLX V6 earned an EPA rating of 25 MPG combined. This comparison is important to GS 200t buyers because while driving experience is a priority, overall cost of ownership is a definite consideration. A few MPG can mean hundreds of dollars saved each year.

Tips to maximize efficiency

Use the GS 200t’s “Eco” driving mode, especially in city driving or heavy traffic. This mode adjusts throttle response and transmission mapping to favor fuel efficiency over performance. It slightly reduces the car’s responsiveness, but can improve gas mileage over time.

Maintain proper tire inflation as shown on the driver’s side door jamb. Underinflated tires increase rolling resistance, making the engine work harder and reducing fuel economy. Check tire pressure regularly, especially when the temperature changes, and inflate tires to the recommended level.

Avoid carrying unnecessary weight. Extra weight in the trunk or on the roof rack significantly impacts fuel consumption. Remove anything non-essential, especially on longer trips, to reduce the load on the engine.

Plan routes to avoid stop-and-go traffic when possible. Driving at a steady speed on the highway offers the best fuel economy. Use navigation apps to find alternate routes or travel during off-peak hours to minimize idling and acceleration.

Consider fuel additives to clean fuel injectors and improve combustion. A clean fuel system ensures optimal engine performance and can help maximize fuel efficiency. Also, explore GS MPG across all years.
