8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.

Lexus IS 250 to get new turbo four?

"All show, no go." That's how I described the 2014 Lexus IS 250 F Sport that you see above, when I reviewed it back in November. Don't get me wrong, there's a lot to like about the new IS, but the 204-horsepower, 2.5-liter V6 in the IS 250 is not on that list. In my review, I suggested that Lexus ought to get on the bandwagon of offering a small-displacement, turbocharged, four-cylinder engine in its base IS (like its rivals), and now the folks at Motor Trend are furthering that discussion.
Lexus pulled the wraps off its new NX 200t crossover at the Beijing show recently, and it'll be the first vehicle in the company's lineup to use a brand-new - you guessed it - 2.0-liter turbo-four. With 238 horsepower and 258 pound-feet of torque on tap, that represents a healthy increase over the 204 hp and anemic 185 lb-ft currently being offered with the 2.5-liter V6, and we imagine the fuel economy gains will be rather significant, too. For comparison, the Lexus' four-pot power numbers are very close to the 240 hp and 255 lb-ft offered in the same-sized engine that BMW uses in the 328i.
Motor Trend also posits that Lexus may consider changing the base IS' name from 250 to 200, or perhaps 200t, to properly reflect the new engine's displacement. Of course, that's assuming Lexus doesn't pull a BMW or Mercedes-Benz, and no longer has its alphanumeric names properly reflect the size of the powerplant found underhood.

Lexus GS production and sales halted in Europe

We last wrote about the Lexus GS one year ago to editorialize about the rumored death of the luxury brand's sports sedan. Now, Dutch outlet AutoRAI claims to have gotten confirmation from Lexus Europe that the automaker stopped taking orders for the GS in March, and will cease production of the Euro-spec model in April. In keeping with last year's speculation, AutoRAI reports the next-generation, front-wheel-drive ES will fill the role of the rear-wheel-drive GS there. What this means for the GS in the States? We sill don't know. But we do know that the ES moved 51,398 units here last year, compared to GS sales of 7,773. Those numbers represent double-digit declines compared to 2016, when the sold ES sold 51,398 units and the GS sold 14,878. In August 2017, spy photographers caught the 2019 ES testing with the Audi A6 and Mercedes-Benz E-Class, hinting the coming ES has grander aspirations than being a florid Toyota Avalon. That still wouldn't make the ES a pure replacement for a sporty rear-drive sedan, but are there enough GS buyers for Lexus to care? Last October, Car and Driver reported that Toyota's Gazoo Racing brand was working on a new GS F, but C/D couldn't tell if Gazoo meant a new model or the current one. Last June, Lexus Australia head Peter McGregor refuted the death of the GS. When asked if dealers were interested in both the ES and GS, McGregor responded, "I think what dealers like is a full line-up... that meets the market requirement in every key segment." Making clear that he couldn't speak on future product, McGregor also commented, "I think [a new GS] would still be a four-door sedan in terms of its application, but the exterior styling may appear to be more liftback." The third-gen GS struck a fastback profile, and you could see the new LS as a modern evolution of that old GS design. A member at the Lexus Enthusiast fan forum has found that the the next GS, internally codenamed 300B, still shows up in industry databases alongside the date "SOP [Start of Production] Q2 2019." Throwing money at an updated GS F wouldn't make sense for a doomed sedan. Could the GS reappear as a four-door coupe? Certainly, if for no other reason than that Lexus needs something to fill the slot between the $38,950 ES and the $75,000 LS.
