The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Lexus LF-NX gets turbocharged second act [w/video]

Don't let its supremely polarizing appearance fool you, this is not the Lexus LF-NX Concept that you (probably) had a strong reaction to when it debuted at the Frankfurt Motor Show. The German version of the concept car featured a variant of the Lexus Hybrid Drive system, while this LF-NX Turbo, well, it has "turbo" in the name, you see?
If fact, the namesake turbo would appear to be the first for Lexus; getting off the line in the forced-induction race with a 2.0T four-cylinder engine that "paves the way for the introduction of turbocharged powerplants in future Lexus models." Sounds good to us. The new turbo four has plenty of tricky tech, too. Lexus tells us that the engine makes use of an advanced high tumble port, fan spray fuel injection, VVT-iw variable valve timing, an exhaust manifold integrated into the cylinder head and, of course, a twin-scroll turbo with active wastegate valve. The result is said to be a blown engine that offers quick throttle response and "exhilarating" performance, along with excellent fuel economy and low tailpipe emissions.
As for the rest of the LF-NX Turbo concept? Well, you've seen this angular concept crossover before, basically. There's a slightly tweaked front end and new wheels sitting in slightly cleaned-up wheel wells. The boldest-yet version of the spindle grille still bears an uncanny resemblance to The Predator, and the slightly revised exterior visuals won't change your made-up-mind about this vision of Lexus' future.

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.
