New Lexus RC F to rival BMW M4

Lexus has confirmed the first details of a new RC F high performance model, which will debut at the Detroit Motor Show 2014 next week. Driven by what’s said to be the most powerful 5.0-litre V8 ever offered by Lexus, the RC F is set to top the new RC coupe range that was unveiled at the 2013 Tokyo Motor Show last November. A spiritual successor to the old Lexus IS F, the RC F will become the first rival to challenge the new BMW M4 later this year.

Concept Car of the Week: Lamborghini Countach LP500 (1971)

The Miura was undeniably gorgeous, but wasn't yet on the same level as the Ferraris in terms of performance.
