Lexus will field two IS 350s in the 2006 American Le Mans Series' GT2 class, the team has been hard at work preparing the cars for their first racing season. The new cars will challenge GT2-class stalwarts Porsche and Panoz while taking on new entries from Ferrari and BMW.
The level of GT2 American Le Mans Series competition underscores the challenges inherent in building a sedan to compete on even terms. Top GT2 competitors include the Porsche 911 GT3 RSR, Ferrari F430GT, Panoz Esperante GTLM and BMW M3—all formidable cars.
With its production-based V6 providing more than 450 hp to propel a race car weighing less than 2,800 lbs., the new IS 350 GT2 promises to be plenty quick. The car also will retain its double wishbone front and multi-link rear suspension, suitably modified for the task and tuned to work with the large BBS-mounted Michelin racing slicks. StopTech will provide an upgraded brake package.
