The Lexus RC F, the high-performance version of the recently launched Lexus RC Coupe, has been officially unveiled at the Detroit motor show.

The RC F is powered by a 5.0-litre V8 engine developing more than 450hp and 520Nm of torque.

It drives the rear wheels through a recalibrated eight-speed transmission, coupled with a torque vectoring rear differential to help maintain traction.

Lexus say the RC F is the most powerful V8 road car they’ve ever built, and it’s also one of the most technically advanced.  The V8 engine, for instance, uses the Atkinson cycle at cruising speeds for increased fuel economy, switching to the more conventional Otto cycle at higher revs to maximise performance.

A new exhaust system alters the induction and exhaust sounds, with a deep engine note up to 3,000rpm replaced by a higher-pitched sound as the revs reach 6,000rpm.

The Torque Vectoring Differential offers three modes of operation – Standard, Slalom (where steering inputs are emphasised) and Track, which focuses on stable cornering.

The company’s Vehicle Dynamics Integrated Management (VDIM) system has been revised to cope with the extra power, and also now includes an additional G-force sensor.

Away from the electronics, the chassis has been stiffened through the use of large cross-section sill panels and a front lower brace, as well as new manufacturing techniques such as laser-screw welding and multi-spot welding.

The styling has been revised to match the performance, with a more aggressive version of the Lexus ‘spindle’ grille with subtle F badging, higher set bonnet, flared wheel-arches, and LFA-style cooling ducts and aerodynamic features.

A choice of three sets of wheels will be offered, all 19-inches in size, one set of which is hand-polished.

An optional carbon-fibre package comprising roof, bonnet and active rear wing will also be available.

The cabin features F Sport instruments, oval-rimmed sports steering wheel, sports seats and bespoke trim.

The only performance figure released by Lexus is an estimated yet electronically-limited top speed of 186mph.
