The big news out of Lexus is the rumor of a twin turbo F variant of the LC 500, which could produce over 600 horsepower. We think a 600-plus hp LC F would be an excellent car, but we shouldn't forget Lexus' current sports coupe, the RC F. By comparison, the 467-hp RC F has never really measured up to rivals like the BMW M4 or Audi RS5, but it does have some of its own unique advantages. Lexus is currently preparing a facelift for the RC, and the company was seen testing a new, hardcore variant of the RC F.

This hotter RC F is rumored to be called the RC F GT, and it will slot between the base car and the stripped out GT3 race car. From the spy shots, we can clearly see an extensive use of carbon fiber for the hood, roof, and side skirts. The RC F GT will also have more aggressive bodywork, with the addition of a spoiler and rear diffuser. Compared to its rivals, the RC F is a heavy car, but this GT model will hopefully cut down on weight.

Along with this new RC F GT model, the entire RC lineup will get a refresh, which may include interior changes and a possible infotainment refresh. We also expect to see revised bumpers across the range, and some possible drivetrain changes. The refreshed RC is expected to make its debut at the 2018 Paris Motor Show in October.
