Lexus RC F to have more than 450bhp Power comes from a 5.0-litre V8 petrol engine that Lexus says is "expected to deliver well in excess of 450bhp." The new BMW M4, which would be a key rival for a production version of the RC-F, has a 3.0-litre, six-cylinder unit that develops 425bhp. A production version of the RC-F is likely to go on sale in 2015 and is expected to have a similar price to the M4, which costs £56,635. Read more about the 2014 Detroit motor show
