Since the limited LFA finished production in 2012, Lexus has needed a halo car to replace it. Potentially, the long-rumored LC F could fill that void as the company's new flagship coupe with performance approaching supercar territory to rival the likes of Porsche, Audi and Mercedes-AMG. Lexus has yet to reveal the high-performance coupe, but rumors have suggested it will be powered by a twin-turbo 4.0-liter V8 producing somewhere in the region of 600 hp.

Those rumors are starting to intensify, as Lexus Enthusiast has revealed new details about the LC F taken from an interview with an alleged company insider by Japanese publication Holiday Auto. Once again, the insider backs up previous claims that the Lexus LC F will be powered by a twin-turbocharged 4.0-liter V8, but confidently states that the coupe's output will be a very respectable 621 hp. In comparison, the current LC 500 has 471 hp on tap enabling the coupe to sprint from 0-62 mph in 4.4 seconds and top out at 168 mph, so the LC F's extra bump in power should result in blistering performance figures.

Furthermore, as well as gaining a new powertrain the insider claims that the LC F will benefit from a seven percent weight loss thanks to extensive use of additional carbon fiber reinforced plastic. The LC 500 is quite heavy, weighing in at 1,941 kg, so the LC F will have shed around 130 kg, which is very welcome. The source also claims that prices for the LC F will start at around 20 million yen ($176,000). For comparison, the LC 500 costs 13 million yen ($115,000) in Japan. Testing of the LC F will reportedly begin next fall before the coupe arrives in dealerships in 2019. While the LFA was made in a dedicated facility, the LC F will roll off the same assembly line as the LC 500 and 500h according to the source.

None of these rumors have been verified yet, though the specific details about the weight reduction make the claims sound more plausible. Hopefully it won't be too long until Lexus reveals some official details about its next flagship coupe.
