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.

2015 Lexus LS gets tiny tweaks to try to keep up in LA

The 2015 model-year updates for the LS are certainly minor, but at least Lexus isn't letting its flagship sedan languish completely. The biggest change for the revised model is an improved infotainment system with an updated navigation and dynamic guidelines for the backup camera. Lexus' Enform App Suite also allows owners to remotely control some of the vehicle's functions, including the door locks, ignition and climate control settings. Among the litany of incredibly small tweaks, the dome lights now use LEDs, and the F Sport model that includes features like a sport-tuned air suspension and 19-inch forged wheels gets an added badge at the rear. The changes have increased the turning circle by 3.9 inches for models with the standard suspension and 18-inch wheels. All of the changes are definitely minor, but hopefully they'll sustain the posh motor until its next iteration is ready. 2015 Lexus LS Shows Why This Luxury Flagship Became A Luxury Legend - New Multimedia System for 2015 - Lexus Enform App Suite Upgraded - Upgraded Backup Camera With Dynamic Gridlines - F SPORT Model With Special Suspension, 19-inch Wheels, Brembo Brakes October 16, 2014 History seems to be repeating itself. The Lexus LS upended the luxury segment a quarter-century ago, and one reason was that it made a powerful V8 engine standard when it was a very expensive extra-cost option in some European models and not even available in others. Just change the year to 2015, and the situation seems to be replaying. A supremely smooth, standard 386-horsepower 4.6-liter V8 teamed with an eight-speed automatic transmission is only one facet of the 2015 Lexus LS 460, though undeniably, it's the one whose benefit you feel quite strongly during a road test. Nearly silent acceleration remains a hallmark aspect of driving a Lexus LS, which also offers the option of a more engaging driving experience with the F SPORT Package. A wide range of model choices also make the Lexus LS a standout. The LS 460 comes in regular and long-wheelbase versions, each with the further choice of rear-wheel drive or all-weather drive (360 hp with AWD). The ultimate Lexus flagship sedan remains the LS 600h L hybrid with 438 total system horsepower from a 5-liter V8 paired with an electric motor and all-weather drive. New for 2015, the LS gains a new multimedia system. The multimedia system, accessed through the navigation screen, provides a multitude of capabilities.

2015 Lexus RC F

I didn't get a chance to drive the Lexus IS F until 2009, two years after the car had gone on sale, but I still vividly remember the day it happened. Having piloted almost every other vehicle in the Lexus lineup at that point, I was stoked to finally get some wheel time in the V8-powered, flared-fender muscle sedan, but fully expected the car to offer a quick, sanitized and ultimately un-driverly experience. Lexus built well-screwed-together, comfortable, quiet, reliable luxury cars for the timid, right?
As it turned out, I was 100-percent incorrect. When the premium brand's lauded "skunkworks team" crammed that massive V8 into the innocent IS, and then tuned the thing for competent hot laps at Fuji Speedway (F = Fuji, if you haven't heard), they seemingly forgot every brand value that Lexus had curated over the previous 20 years. It was raw and loud, had fast-twitch reflexes and a penchant for power slides, and it went unyieldingly across the road surface like a racecar cut loose from the paddock.
As far as Ur- models and origin stories go, the IS F and Lexus F has a pretty compelling, if new, set. A backdrop against which the sequel, this 2015 RC F, must inevitably be viewed. Sure, the otherworldly LFA may have intervened as the second F model, but the RC carries forward an evolution of the 5.0-liter V8 thumper, some shared body and chassis constructions, similar in-your-face design and a ticket price that's squarely in the mix for premium buyers with a hankering to smoke tires.
