Set to be publicly unveiled at the forthcoming North American International Auto Show (NAIAS) in Detroit, the new Lexus GS F picks up the performance baton from the just launched RC F coupé. The new super saloon will face some stiff competition from the likes of the BMW M5, Audi RS 6 and Mercedes-Benz E 63 AMG.
Exterior
The standard GS in F Sport trim isn't a bad looker, but the GS F leaves no room for mistaking its purpose. Its front-end, dominated by an already large grille, is now flanked by two not-unsubstantial air intakes to help feed and cool the engine. New daytime running lights and headlamps also make up the new face, both of which are likely to make their way across to the standard model as part of a model update.
At the rear are a pair of stacked exhaust pipes that hark back to the original Lexus IS F and link in with the rear styling of the new RC F. Large lightweight multi-spoke alloy wheels accommodate the uprated brakes.
Interior
Of what we have seen thus far the main interior architecture and layout remains largely unchanged; however, the addition of supportive sports seats along with carbon fibre trim panels across the dashboard fascia and doors does reiterate the high-performance nature of the car.
Mechanicals
Engine-wise the new GS F gets the same high-revving naturally aspirated V8 as the RC F, which produces 477hp at 7,100rpm and 530Nm from 4,800rpm. There is no word yet on exact performance figures, but considering that the two-door RC F completes the dash from rest to 100km/h in just 4.5 seconds, the larger GS F shouldn't be too far behind.
Anything else?
Despite the serious performance, Lexus is still keen to keep one eye on emissions, hence expectations are that the 5.0-litre V8 engine of the GS F will be capable of splitting its operation between Otto and Atkinson combustion cycles to place more emphasis on power or emissions depending on the demands of the driver.
