A couple of days ago we brought you some spy shots of a mystery Lexus LS undergoing testing at the Nurburgring. We weren't sure if it could be a possible LS-F, but we could tell that Lexus was serious about adding some serious power to their otherwise boring flagship sedan. And now our source has sent us this single photo of a document stating what the car is and its details. According to it, the car is called the LS-TMG Edition and it has an output of 650hp and 710 lb-ft of torque.

It can go from 0 to 62mph in 4.2 seconds and has a top speed of 320km/h, or about 196mph. We're guessing that there's some form of forced induction at work here, but until Lexus makes any official announcement, this is pure speculation.
