The Lexus RC F GT Concept will be the luxury marque's entrant in this year's Pikes Peak Hill Climb.
According to Lexus, the RC F GT Concept weighs around 1420 kilograms or at least 360kg less than the road going RC F coupe, thanks in part to a stripped out interior and the use of expensive lightweight materials throughout.
For example, the GT Concept features carbonfibre roof, doors, bonnet, boot lid, outer fenders, rear spoiler, interior trim and dashboard. Glass windows have also been replaced by polycarbonate.
Under the bonnet, the RC F GT Concept uses the same the 5.0-litre naturally aspirated V8 engine and eight-speed automatic transmission as the road-going vehicle, although the "states of tune are adjusted for the competition environment".
The road-going RC F's V8 develops 351kW of power and 530Nm of torque. The GT Concept rides on 18-inch alloy wheels fitted with 265/40 Yokohama Advan Neova tyres up front and 280/680 Yokohama Advan A005 racing slicks at the rear.
The RC F GT Concept will be piloted with Justin Bell, a former class winner at the 24 Hours of Le Mans. The company hints that a future version of the RC F GT may be used in the upcoming global GT3 championship.
Lexus also notes that components from the IS F CCS-R cars, which were raced in the Pikes Peak Hill Climb until 2013, "helped develop key components such as the engine and transmission for the 2015 RC F". Parts and settings from the RC F GT Concept may also trickle down in the the production car.
