This is my third Lexus LS, following a 2001 and a 2004 LS 430. Honestly, the two earlier cars were much quieter, as if powered by a huge electric motor. The driver's seat was more comfortable and its cushion extended farther forward to support under my legs. (I am 6'3" tall.) Other than that, the 2010 is a much-improved car. The motor has direct injection at very high pressure and it idles like a diesel - very noisy, especially compared to the earlier two cars - but the horsepower and torque are much greater. The optional adjustments to the transmission and suspension change the character of the car, unlike in other premium cars. Reliability is a luxury in itself - this car never breaks.
Horsepower and torque. All wheel drive with high suspension adjustment makes it a luxury SUV to get through deep snow or gravel roads with ease. Rear seat legroom is impressive to everyone who gets in the back seat. Heated steering wheel should be standard in all cars. Everything in and about this car always works - never a down moment in four years. Electric screens on rear side windows make other luxury sedans with manual screens seem cheap. The interior has 95,000 on it and looks brand new. With the traction control and stability control turned off (how did we drive before these systems were invented?), the transmission in "Power" and the suspension in "Sport," this car really hustles.
More horsepower comes with reduced gas mileage - makes sense but one would think with modern technology Lexus could have given more power and maintained efficiency. My 2001 and 2004 LSs averaged 20 mpg all-around over 200,000 miles; the 2010 averages 18.9 over 95,000 miles of same daily driving. Exterior styling is bland, but at least it is not as disappointing as driving an "all new" 2013-2014 that looks nearly the same. To compete in its class, the LS needs significantly more horsepower and torque.
