| Lexus GS Fuel Economy: Pros | ||
| Year | Body/Powertrain | Comment |
| 2009 | 4dr Sedan 303-horsepower 3.5L V6 6-speed shiftable automatic RWD |
I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. |
| 2008 | 4dr Sedan 292-horsepower 3.5L V6 Hybrid 6-speed shiftable CVT RWD |
For 340 hp and a 0-60 of 5.2 seconds, I consider an average of 24 in the city and 33 on the highway to be incredible. If you really feather the gas and stick to 65 on the highway you can get around 36-38 mpg. |
| 2007 | 4dr Sedan 292-horsepower 3.5L V6 Hybrid 6-speed shiftable CVT RWD |
Low consumption in city and stop and go traffic Significant fuel savings in typical German highway driving - plenty of acceleration to and braking from high speeds. The hybrid drivetrain minimises the cost of this compared to conventional petrol power |
