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.

Next-gen Toyota Tacoma to debut at Detroit Auto Show

Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups. The next generation of the Toyota Tacoma pickup truck will be revealed in January at the Detroit Auto Show, a top executive confirmed Thursday. Bob Carter, senior vice president of automotive operations for Toyota, offered no other details, but the new version of the pickup is expected to have significant upgrades compared with the aging model on sale now. Our spy shooters caught a prototype testing this summer, and rumors of the new generation have been swirling for months. We've also previously reported that Toyota is planning to ramp up production next April at a factory in Mexico that builds the Tacoma. Toyota's confirmation comes on the heels of General Motors' successful launch of its own midsize pickups, the Chevrolet Colorado and GMC Canyon, which have garnered awards, positive reviews and solid sales since they arrived in showrooms this fall. It's unclear how large the new Tacoma will be, especially considering that the Canyon and Colorado flirt with fullsize territory. The Tacoma was last updated in 2012, and the segment has changed dramatically since then with the addition of the GM trucks. Another Tacoma competitor, Honda's aging Ridgeline, is also expected to re-launch in 2015, which would leave the Nissan Frontier as the oldest truck in the field. Tacoma sales have slipped 4.1 percent to 140,757 units this year, though they posted a 3.3-percent gain in November. Meanwhile, Carter also said Lexus will reveal two performance vehicles, though he didn't elaborate. "I'll leave it at that, but I promise you'll enjoy it," he said coyly. Lexus just showed the LF-C2 convertible concept at the Los Angeles Auto Show.

Lexus IS to get Deviant at SEMA

It's time to start gathering intel on SEMA, and it starts with this drawing of a modified 2014 Lexus IS. Lexus ran a competition on DeviantART, an online community for artists, to find a suitably modified IS that it could build and display at the temple of all things aftermarket in Las Vegas. The winner, as judged by a four-person panel from among more than 600 entries, is the IS rendered above by Rob Evans.
The winner looks like the beginning of a build for an IS entry into Japan's Super GT series, with a seriously exaggerated front spoiler and rear diffuser and fender flares that aren't just punched out, they're throwing 12-punch combinations.
Evans will have his car built by VIP Auto Salon and plastered all over Lexus materials promoting its presence at the show. Oh, and he gets an IS F-Sport for a year, among other prizes. Second place went to Lucia Lee, third place to Guangho Huang. A press release below has more on the competition and the winner.
