The all-new Lexus RC F takes a bow at the North American International Auto Show.

The aggressive new Lexus RC F coupé is equipped with a new 5.0-litre engine with engine power well above 450hp.

The model has been styled for optimum high speed stability, necessary to support the most powerful V8 performance car ever developed by Lexus.

It has wider wheels and tyres, an active rear wing, air scoops, cooling ducts and carbon fibre components, each delivering what Lexus describes as "functional beauty".

"The form of each component is carefully designed to contribute to performance," Lexus RC F chief engineer Yukihiko Yaguchi said.

"Unique air outlets in the hood and rear section of the front fenders contribute to optimum engine cooling and handling stability. They create an aggressive look that immediately conveys the expectation of a dynamic driving experience."
