GSR-Premium is for the Japanese market only but could preview a new model for the U.S.
Highlighting the list of updates is a more powerful engine, which is now rated at 296hp (221kW) and 311lb-ft (421Nm) of torque, as well as the introduction of the new ‘GSR-Premium’ flagship. The previous model was rated at 276hp (206kW). The transmission options remain unchanged, and consist of the standard six-speed manual and Twin Clutch SST.
The upscale GSR-Premium model gets a pair of Recaro leather seats as standard, a nine-speaker Rockford Fosgate stereo system and a 30GB hard-drive and sat-nav system.
Distinguishing the new lineup are newly designed 18in BBS alloy wheels, body-coloured vents, custom side sills, a revised instrument panel and new door sills. Rounding out the list of performance upgrades are Bilstein dampers and Eibach springs, as well as new Brembo sport pads. The Japanese launch is scheduled for the end of this month.
