New Toyota Supra may get a twin-turbo Lexus V6

We've heard endless rumors that a successor to the much loved and much missed Toyota Supra is in the works. Toyota hasn't done much to deny these conversations. On the contrary, the FT-1 concept from two years ago and the partnership with BMW have only fueled the fire. Now, talk of a new Lexus engine has led to speculation about the supposed Supra's powertrain. To be clear, this is mostly heresay. Few things have actually been confirmed, but based on what we know a few conclusions can be drawn. We know that BMW and Toyota are working on a joint product. We've seen mules testing out in the wild. In BMW guise, the possibly Austrian-built car will more than likely powered by turbocharged inline four and six-cylinder engines. Unless Toyota wants to use Bimmer power, they'll need to shoehorn one of their own under the hood. That leads us to this rumor of a twin-turbocharged V6 that will presumably power the new Lexus GS and LS. Japanese automotive publication Mag-X first reported on this engine. It was then picked up by YouWheel and Car Keys. Mag-X cites Toyota insiders and even gives an engine code, 943F. This engine allegedly will make more than 400 horsepower and more than 300 lb-ft of torque. While unconfirmed, this makes sense for Lexus. Nearly every luxury competitor has a six-cylinder engine with forced induction. While Toyota has previously had turbocharged inline-sixes, they've never produced a factory turbo V6. Every automaker is downsizing engines in an effort to meet fuel economy and emissions regulations. Toyota and Lexus will follow suit. Taking that V6 and tuning it for a performance application is a solid, if unverified, possibility. Related Video:

2018 Lexus LS First Drive | Luxury, performance and the puzzling parts

When one imagines the enormous executive sedan that might be driven by a wealthy lawyer or banker (or their chauffeur), the mind naturally goes to the Mercedes S-Class or the BMW 7-Series. Venerable, enormous and expensive. But for those wanting to keep their driveway a little more understated, we also have the Lexus LS. Sure, it's not as ostentatious as the big saloons from Munich and Stuttgart, but it has a dignified elegance all its own. For nearly three decades, the LS has been a discrete and dependable Japanese luxury sedan. The new 2018 LS, perhaps thankfully, is a bit less discrete. We saw the new-look LS when it was introduced earlier this year in Detroit. Now we know how it drives. We put the 2018 LS through its paces on the traffic-clogged streets of San Francisco and over the Golden Gate Bridge to the twisty B-roads around Marin County and the legendary Skywalker Ranch, where we stopped for lunch. Unfortunately, all in attendance were sworn to secrecy about the details of Skywalker Ranch, but we're free to tell you all about the LS. Here's our one-sentence summary, which can be used to describe many cars to bear the Lexus badge: It's excellent in many respects, odd in a few, and incredibly, massively frustrating in one very important area. Lexus has a brand new 3.5-liter twin-turbocharged V6 paired with a 10-speed automatic transmission, a first for a premium passenger car. It produces 416 horsepower and 442 pound-feet of torque, up from 386 hp and 367 lb-ft from the outgoing naturally aspirated 4.6-liter V8. Lexus engineers are extremely proud of the fuel efficiency of the new engine, which required some clever technical innovations (a longer bore stroke and increased valve angle) as well as tech borrowed from Formula One, including a "laser clad valve seat" that allows for a more direct flow of air into the combustion chamber and a high "tumble ratio." In other words, Lexus figured out how to get more bang out of each gasoline-powered buck. Fuel economy numbers are 19 city, 29 highway, and 23 combined for the RWD version and 18/27/21 for AWD, with the highway numbers particularly helped along by the 10-speed gearbox. It's a torque converter unit, but Lexus promises shift times that rival its dual-clutch-wielding competitors. The LS is no slouch, either. In RWD trim, the nearly 5,000-pound car hustles from 0-60 mph in 4.6 seconds, according to Lexus' reckoning.

Lexus US execs want the LF-1 Limitless concept or something like it

Many years ago, Mercedes-Benz counted many blue moons debating about and then hinting at a full-sized SUV, before the GLS-Class arrived in 2007 (known then as the GL-Class). After that, Audi and BMW each grabbed a gilded handle on The Waffler's Cup, equivocating for years about a Q8 and an X7, respectively; both of those luxurious load-haulers are expected in showrooms soon. Having seen the Lexus LF-1 Limitless Concept at the Detroit Auto Show, we wonder if Lexus intends to hoe that same row - dodging years of questions about a production version of the LF-1 Limitless before finally committing. Lexus US general manager Jeff Bracken hopes that's not the case. His address to the unveil audience at the NAIAS included the appeal, "We have to build this vehicle," aimed at his boss, Lexus global chief Yoshihiro Sawa. Bracken stoked the flames of his own desire after the reveal, telling journalists, "We couldn't be happier if we turned this into a production vehicle," and, "We clearly have a gap at the high-end premium cross-utility segment." We're certain plenty of his colleagues share the sentiments, and why wouldn't they? A Lexus LS-based family functionary begs the question, "Why isn't this already a thing?" The LF-1 Limitless does fierce, futuristic service to its Ghost in the Shell design philosophy of "molten katana," and Lexus needs a proper three-row crossover. Not the three-row RX, nor the opulent, cretaceous GX and LX SUVs, but a unibody crossover to challenge the aforementioned German rivals. If Lexus really does "want to be the brand which is emotionally connected with the customer," it would do well to begin its courtship with this rose-copper gem.
