A prototype of the upcoming Lexus GS F has been spied undergoing testing near and on the Nürburgring in Germany.

According to our sources, Lexus was benchmarking this red GS F prototype against a BMW M5 so it's clear the high-powered GS is aiming at the M5 clientele. Under the hood it will reportedly get a V8 5.0-liter engine sourced from the RC F where it delivers 467 bhp (348 kW) and 526 Nm (389 lb-ft) but in the GS F the motor will be further tweaked to develop as much as 500 bhp (373 kW) and 541 Nm (400 lb-ft).

Mated to an eight-speed automatic gearbox, the Lexus GS F is expected to run the 0-60 mph (0-96 km/h) sprint in about four and a half seconds on its way to a top speed of more than 170 mph (273 km/h). Matching these impressive numbers will be an aggressive body kit with large air intakes and a massive front spindle grille. Also on the menu there are bigger alloys, a quad exhaust setup, rear diffuser and beefier brakes.

Also from the RC F, the upcoming GS F will reportedly borrow the strut front & multi-link rear suspension setup along with the rear-wheel drive chassis configuration and other mechanical components.

According to a recent report, the Lexus GS F will be available for order in the fourth quarter of next year as a 2016MY, with pricing starting at an estimated £80,000.
