TrueDelta Reviews the Real Gas Mileage of the Lexus GS

Lexus GS Real Gas Mileage: Cons
YearComment
In casual suburban driving the trip computer reported between 22 and 23 mpg, splitting the difference between the EPA ratings of 19 city and 26 highway. When I made the engine sing mpg dropped into the high teens. Slip into Eco and drive the GS like a Prius, and 25 is barely doable. Not bad for a 306-horsepower, two-ton, all-wheel-drive sedan. But the torquier Audi A6 3.0T and BMW 535i xDrive do a little better, especially on the highway. The Teuton's turbos help a little here, but most of the blame/credit goes to their respective transmissions. If and when Lexus fits the GS AWD with the eight-speed automatic already offered in the RWD car, it'll likely catch up. see full Lexus GS review

I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. see full Lexus GS review

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. see full Lexus GS review

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 see full Lexus GS review

I was hoping for slightly better fuel economy, but for a 4500 lbs vehicle, I really shouldn't be complaining. In predominantly hilly suburban driving, I'm averaging a couple miles below the estimated city fuel economy number. On 100% hilly highway miles, I'm right about at or maybe 1 mpg above the estimated fuel economy. It would be nice to acheive better highway mpg, but I suppose that's the trade-off for having a torquey engine. You would think the CVT would improve things, and maybe in fact it is helping the poor fuel economy of the aging VQ engine design, but I also think the CVT transmission is a cost-cutting measure by Nissan. It would be nicer to have one of the 7 speed transmissions found in the Infiniti lineup. see full Nissan Quest review
