The first development test-mules for the next-generation model of the Lexus GS luxury sedan that’s due next year have been spotted. The current Lexus GS luxury sedan has been on the market since the 2006 model year so it’s definitely good timing, especially since the new Mercedes-Benz E-Class and BMW 5-Series, and the next-generation Audi A6 will soon be launched.
In these latest spy shots of the upcoming model, it seems that overall length was cut slightly, but the wheelbase is expected to remain at 112.2 inches. These modified wheel arches suggest that the new Lexus GS will get a slightly wider track.
It’s believed that the next-gen model will have a brand new platform, and will be sportier and more efficient. The 2012 Lexus GS is believed to feature a downsized V-6 engine that will replace the current 3.5-liter mill as the entry-level option.
Meanwhile, the 3.5-liter engine will replace the current 4.6-liter V-8. A hybrid model is expected to return, and is likely to be based around the entry-level V-6 engine.
The regular V-8 model will be dropped but a high-performance GS-F model will be offered for the first time.
But instead of featuring a high-revving 4.8-liter V-10 of the LFA supercar, the next-gen model will have an uprated version of the 5.0-liter V-8 from the IS-F that delivers 450hp and is expected to start selling in 2013.
Special features include a torque vectoring differential on the rear axle and plenty of carbon-fiber to drop some weight. [via MotorAuthority]
