Much like the larger GS sedan that we recently spied, Lexus is apparently working on a substantial overhaul for its smaller rear-drive IS, as well.
Though still in early test mule stages, the next IS is expected to ride on a shorter version of the GS platform, which could give it a slightly wider stance than the car currently on the road. Expect the usual sedan and convertible variants to be on hand, as well as a forthcoming IS coupe set to battle the BMW 3 Series and upcoming Mercedes-Benz C-class two-door.
The reworked IS sedan will likely bow sometime in 2012 and the coupe is pegged to arrive shortly thereafter with the usual V6 powertrains as well as an eventual high-performance F variant in at least one bodystyle. The only question we have is, will a force-fed four powerplant also join the party?
