According to their information it's called the Lexus LS TMG Edition, and the TMG stands for Toyota Motorsport GmbH. That would be the European motorsports branch for the Japanese automaker, which helps to explain the Cologne plates spotted on the car. According to the spied spec sheet, the LS TMG boasts a 5.0-liter V8 engine that produces 641 horsepower and 524 pound-feet of torque. That should be enough to push the large luxo rocket from 0-62 miles per hour in 4.2 seconds and on to a top speed that's a hair under 200 miles per hour.
While we have no idea whether this is a production prototype, a one-off exercise or something else entirely, the very existence of a 641-horsepower, 200 mile-per-hour Lexus LS suggests that the crew behind the LFA are holding increasing sway over the Toyota luxury asylum. Needless to say, we're okay with that.
