The standard RC F features a range of visual and mechanical modifications aimed at maximising performance, according to Lexus. Weight has been saved by replacing the old model’s solid half-shafts with lighter, hollow units, while components such as the intake manifold and air-conditioning compressor are now smaller.
Lexus claims to have improved handling performance by using aluminium suspension parts, stiffer bushings and steering rack mounts, and new Michelin Pilot Sport 4S tyres developed especially for the new RC F.
The BMW M4 rival retains the previous RC F’s 5.0-litre naturally aspirated V8, which, with modifications to the intake system, now produces 451bhp and 384lb ft at 4800rpm. The eight-speed automatic gearbox has been kept, but now features a higher final drive ratio to improve acceleration from a standing start. With launch control fitted as standard, the RC F is capable of a 4.5sec 0-62mph time.
Changes to the RC F’s exterior styling include redesigned headlight clusters with integrated daytime running lights, while a new vent at the bottom of the front grille, reshaped bumper and new tail-lights most clearly differentiate this from the old model.
The RC F range now features the RC F Track Edition, a lighter, stiffer version of the standard car that offers driving enthusiasts “the ability to impress on the track and off”.
Developed in conjunction with Lexus’s Super GT and IMSA race teams, the Track Edition features a number of modifications aimed at maximising aerodynamic efficiency and enhancing handling performance.
A redesigned carbonfibre front splitter and spoiler are said to offer improved steering response and up to 26kg additional downforce over the standard model, while weight savings of between 70kg and 80kg have been achieved with carbon-ceramic brake discs, carbonfibre body panels, titanium exhaust components and lightweight 19in BBS alloy wheels. Performance details are scarce, but 0-60mph is said to be dispatched in under four seconds.
