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 tighter turning radius, new infotainment

Go back a couple of decades and the thought of a Japanese automaker challenging the German limousines would have seemed laughable, but 25 years later the Lexus LS is a mainstay of the luxury sedan market. And it didn't get there by sitting on its laurels, so it should come as little surprise that Lexus is offering some small tweaks as it enters the 2015 model year.
This time around the upgrades are rather minor, consisting primarily of a new multimedia system. It's got an updated navigation system with 12.3-inch display, revised backup camera imagery with dynamic gridlines, and an enhanced Lexus Enform App Suite that can control the locks, ignition, climate control and more, remotely.
While they were at it, Toyota's engineers also reduced the turning circle by four inches (on cars fitted with 18-inch wheels), and enhanced the F Sport package as well. Otherwise, it's essentially the same LS we've always known.

Lexus launches supercharged LX 570 in Middle East

The Lexus LX SUV is a very muscular, old-school vehicle. Based on the Toyota Land Cruiser, it's still a big, body-on-frame SUV, but inside it offers acres of leather and luxury tech. The brand's Kuwaiti distributor is taking it machismo even further for the local market with the new LX 570 Supercharger.
As the name suggests, the upgraded SUV grafts a supercharger onto the LX 570's 5.7-liter V8 to boost it to 450 horsepower, from 383 hp in the naturally aspirated version in the US (or 362 hp in the standard Kuwaiti version), and it uses the same six-speed automatic as the standard model. To signal the improved strength, much of exterior chrome is replaced with black trim. It also wears special 20-inch wheels and a rear spoiler. The interior is fitted with crimson leather seats and red-accented carpet. It also gets an aluminum sill plate that says "Supercharger." Like the standard Kuwait-spec LX 570, it has two fuel tanks with a total combined capacity of 36.46 gallons, which should help satiate the likely thirsty, forced-induction V8.
The LX 570 Supercharger won't be rumbling down streets outside of the Middle East, though. According to Lexus spokesperson Bill Kwong, this is a project by the distributor in the region. The supercharged engine also has "issues with emissions" in the US, especially in California, he told Autoblog. Too bad, it would be an interesting Range Rover alternative.
