While BMW deemed the CSL M3 unfit for consumption, the good folks at Lexus have managed to ease our pain at the lithe Bimmer’s passing with word that the Japanese lux manufacturer is planning a light-weight IS-F. The delicious 416 hp 5.0-liter V8 already manages to, uh, scoot the sizeable sedan along, but you know our feelings on more speed through less weight. We can’t wait to get one of those slim-downed suckers on track for some serious hooning. Lexus also mentioned that while the SC convertible won’t soldier on, the company is planning an IS-based drop-top. Oh yes. [Autoblog]
