Our trusty spies have scored another touchdown with the high-performance, wide-body Lexus LS saloon that has piqued our interest over the past few days. 
We already know it is called the Lexus LS TMG Edition and that it is being developed by the Japanese group's Toyota Motorsports GmbH division, formerly known as Toyota Team Europe, based in Cologne, Germany.
Toyota's subsidiary was responsible for firm's World Rally Championship cars starting from the 1970s right up to the 1990s, but now works on various special projects.
Thanks to the leaked spec sheet, we also learned that under the hood of the LS TMG Edition lies a 5.0-liter engine capable of spinning up to 9,000 rpm cranking out a husky 650-ponies and a peak torque of 710Nm (524 lb-ft).
While there are no other details on the engine, the spec sheet notes that the 2,070kg (4,564 pounds) LS TMG completes the 0-100km/h (62mph) sprint in 4.2 seconds and can reach a top speed of 320km/h (199mph).
The new scoop video not only gives us a better view of the Lexus LS TMG Edition as it laps the Nürburgring, but it also allows us to hear the 5.0-liter engine, which brings us to today's question: Having listened to the sounds of the LS TMG, do you think it's a V8 unit, possibly sourced from the IS-F, or a V10 derived from the LFA?
