The latest in Lexus’ line of rear-wheel drive vehicles was unveiled during the Tokyo Motor Show with both a 3.5-liter V6 that makes 314 hp or a 2.5-liter mill mated to a hybrid drivetrain. The 3.5-liter powered model comes with an eight-speed automatic pulled from Lexus’ scintillating IS-F. Despite the apparent similarities with the IS sedans, this car actually shares its platform with the larger GS.
