The officials from Toyota Motorsport GmbH (TMG) have released a set of photos and new details about their Sports 650 concept. This prototype is based on a pre-facelift Lexus LS and is described as a "high-end limousine-sized car which is equally comfortable and exciting on the road as on track days."
On the exterior, we see an aggressive and sportier body kit that includes a new bumper, a restyled grille and a ventilated hood. We also can see a set of carbon fiber side skirts a new rear bumper with an integrated air diffuser and a four tailpipe exhaust system. 
The power comes from a twin-turbo 5.0 liter V8 engine that produces 650 HP and develops 710 Nm of torque. The power is sent to the wheels via an eight speed automatic transmission. Thanks to these figures the Sports 650 can sprint from stand still to 100 km/h in just 4.2 second, while the top speed is clocked at 320 km/h. 
"This is a truly remarkable car with incredible performance; we are looking forward to hearing the reaction of visitors to this showcase of TMG’s engineering capabilities", said Yoshiaki Kinoshita, TMG President.
