TMG still developing Lexus LS Sports 650 [w/video]

If you're going to make a super sedan, you'd better do it in Germany. That's where Audi, BMW and Mercedes-Benz do it, along with third parties like Alpina, Brabus and G-Power, among others. Deutschland is the epicenter of the movement, regularly churning out the most powerful four-door rockets in the world. It's also where one of the racing divisions for Toyota has been hard at work on the TMG Sports 650.
Toyota Motorsport GmbH started with a Lexus LS and turned it into a 641-horsepower, twin-turbocharged super sedan it revealed late last year at the Essen Motor Show. But though we haven't heard much about it since then, the team behind Toyota's F1 and Le Mans efforts are apparently still hard at work on the project.
Speaking with Lexus' own UK blog, TMG chief Alastair Moffitt revealed that the project started way back in 2010, shortly after Toyota shut down its F1 program and left the racing team with nothing to do. The 5.0-liter twin-turbo V8 was initially producing as much as 800 horsepower, but has since been refined to 650 so that it could theoretically be put into production and onto the road.

Lexus NX debuts in turbocharged and hybrid guise

Lexus showed off its polarizing new NX at the 2014 Beijing Motor Show, trotting out both the turbocharged 200t model (Lexus' first production turbo) alongside the hybrid-powered 300h.
We still don't know a great deal about the turbocharged model, aside from the fact that the engine underhood is a 2.0-liter four-cylinder, although we're hoping to get details sooner rather than later. For reference, the 2.0-liter turbo in the BMW X1 pumps out 240 horsepower while the four-pot turbo in the Mercedes-Benz GLA250 turns out 208 horsepower, which leads us to think we should expect the Lexus to fall somewhere between these two figures.
If Lexus' naming strategy in the past rings true here, though, we can confidently say the 300h will use a 2.5-liter four-cylinder Atkinson cycle engine with an electric motor and lithium-ion battery, just like the Lexus ES300h and Toyota Avalon Hybrid. That should mean around 200 system horsepower and well over 30 miles per gallon, although it's probably too early to predict economy with any degree of certainty.

TMG Lexus LS Sports 650 destined for production after 2015?

There's little question that Lexus has succeeded in challenging its German rivals in the luxury marketplace. And with the LFA, it has proven that Japan can build a world-class supercar. What's left blank is the space in between.
Toyota Motorsport GmbH came up with a compelling answer in the form of the Sports 650 prototype, a Lexus LS with a 5.0-liter twin-turbo V8 producing 641 horsepower and other go-fast components to challenge the likes of the Mercedes-Benz S63 AMG and Audi S8. Toyota boss Akio Toyoda was reportedly so impressed with the project that he initially ordered TMG to build ten examples - one for him and each of his nine best friends. But since the model on which the project was based has since been replaced, questions remain over the project's fate.
Georg Kacher - European correspondent for Automobile and Car magazines - recently drove the prototype and reports that "the project will now likely be transferred to the new model out in 2015." That could come down purely to speculation, but Kacher tends to get the inside line on industry news, so this particular bowl of gossip soup might not requite the usual grain of salt we otherwise might add.
