This text was not translated, because it is originally in English Developed to challenge brawny luxury coupes like the BMW M4, the RC F cranks up the performance with what Lexus promises will be the most powerful V8 in any of its cars. It doesn't take a genius to see that means this go-fast version of Lexus' upcoming RC will at least match the 416 hp generated by the 5. 0L V8 in Lexus' IS F sedan.
