With around 306 horsepower on tap, the GS 350 can accelerate from 0 to 60 mph in approximately 5.7 to 6.0 seconds, depending on the specific model and drivetrain configuration. This makes it a reasonably quick car that can handle both city driving and highway cruising with ease. The engine delivers power smoothly across the rev range, providing ample torque for confident overtaking and effortless acceleration. The six-speed automatic transmission complements the engine well, offering smooth and precise gear changes. The transmission also features a manual shift mode, allowing drivers to take more control over gear selection when desired. The AWD system further enhances the driving experience by providing improved traction and stability, particularly in wet or slippery conditions. This gives drivers added confidence and control, making the GS 350 AWD a capable all-weather performer.

Turning our attention to fuel efficiency, the 2008 Lexus GS 350 achieves respectable numbers for its class. According to EPA estimates, the GS 350 typically achieves around 19 mpg in the city and 26 mpg on the highway. These figures can vary depending on driving habits, road conditions, and vehicle maintenance. Drivers who prioritize fuel efficiency can adopt techniques such as maintaining a steady speed, avoiding hard acceleration, and ensuring proper tire inflation. Regular maintenance, such as keeping the engine properly tuned and replacing air filters, can also help optimize fuel economy. The GS 350 also features various technologies aimed at improving fuel efficiency, such as the aforementioned VVT-i system and lightweight construction materials. The VVT-i system optimizes valve timing to improve combustion efficiency, while the use of aluminum alloy in the engine and body reduces overall weight. These features contribute to better fuel economy without sacrificing performance. Overall, the 2008 Lexus GS 350 offers a compelling blend of performance and fuel efficiency. It provides ample power for enjoyable driving, while also delivering reasonable fuel economy for daily use.
