I bought a 2009 GS 350AWD demo vehicle. Previously I owned a 2007 GS350RWD. The 2009 GS350 is much slower than my 2007 and is slower than an ES350, a Mini-Cooper S, a Cadillac SRX, just about everything except the new Fiat 500. I have spoken to the Lexus service, but they say it is because it is AWD. I don't believe them. This car is slow. Has anyone heard of this? Could it be the wrong software being loaded in the CPU? Are they worried that the AWD won't survive the power so it is detuned? Is it a Variable Valve Timing Issue? Help!
