 However, some criticisms were that its steering was not as communicative as that of some rivals, the rear seat legroom (while improved over the first generation) was still tight, and that the six-speed manual was only available on the IS 250.However, the IS' performance has also been praised, for example in a February 2007 "Road & Track" Japanese luxury sports sedan comparison, in which the IS 350 took first place.Introduced for sale in European markets in 2006, the IS 220d (ALE20) was the first diesel-powered Lexus ever produced.
