how is it possible that the GS is lighter than the Is?I had heard that the GS F program was cancelled. If they are moving ahead with it that would be cool. abyars, if you read the whole article, it says that Lexus has a target weight of 3530 lbs. I'm pretty sure the CTS-V is about 4300 lbs. A 3530 lb car with 464 hp would actually be a little faster than a 4300 lb car with 556 hp.
