2015 Lexus GS F to make Goodwood bow

The Lexus GS F will make its dynamic debut at the Goodwood Festival of Speed this month.

The BMW M5-rivalling super-saloon will be driven up the hill by Mike Conway from Toyota Gazoo Racing.

Other Lexus models on show at Goodwood will include the LFA and the RC F GT3 competition car.

Seen officially for the first time in Detroit, the new Lexus GS F uses a normally aspirated 5.0-litre V8 engine with outputs of 467bhp and 389lb ft.

In the high-revving V8, which is a more potent version of the engine seen in the RC F, peak power arrives at 7100rpm with peak torque delivered between 4800 and 5600rpm. Performance figures have yet to be revealed, but we’d expect a 0-60mph time of around 4.5sec and a top speed in excess of 170mph.

A key differentiation point to rivals including the M5, Jaguar XFR-S and Mercedes-Benz E63 AMG is that the GS F’s engine is normally aspirated rather than using forced induction.

The M5 uses a twin-turbo 4.4-litre V8 with 600bhp in its most powerful guise, the E63 AMG features a twin-turbo 5.5-litre V8 with up to 585bhp and the XFR-S is powered by a supercharged 5.0-litre V8 with 542bhp.

Those GS F engine outputs are for the US version of the car seen in Detroit, with European versions set to follow later this year. In the US, the GS F will also line up against the new 640bhp 6.2-litre supercharged V8 Cadillac CTS-V, which makes its world debut at the Detroit show.

The GS F’s V8 will send drive to the rear wheels through an eight-speed automatic gearbox, which features a manual shift mode.

Lexus says the GS F has had its chassis stiffened over that of the standard GS saloon on which it is based. The chassis will feature “structural reinforcements and an exclusive suspension package [strut and multi-link] designed to optimise the car’s handling capabilities and ride quality”.

Weighing in at 1830kg, the GS F undercuts the BMW M5 by 115kg and the E63 AMG by 40kg, making it the lightest model in its class.

The GS F is equipped with Lexus’s Torque Vectoring Differential as standard. It includes three modes: Standard, Slalom (which improves steering response and agility), and Track (for circuit driving).

Design wise, the GS F builds on the look of the standard car and features several aggressive-looking F aerodynamic and styling additions, including new front and rear bumpers, flared wheel arches, side skirts, a rear diffuser and a subtle lip spoiler. Quad exhausts feature at the rear.

The GS F rides on 19in alloy wheels front and rear. The front wheels are shod in 255/35 R19 tyres while the rears use 275/35 R19s.
