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.

The refreshed 2018 Lexus NX looks just like a baby RX

The refreshed 2018 Lexus NX compact crossover debuted this week at the Shanghai Motor Show. Most of the changes are visual, and it should keep the NX fresh for the next few years until more extensive changes come. Power and performance remain the same, but Lexus claims its smallest SUV is quieter and more refined thanks to some updates under the skin. As the automaker's third best-selling vehicle in 2016, behind the venerable RX crossover and ES sedan, the NX has been a huge hit for Lexus in every market. Up front, the love it or hate it spindle grille remains, though it has received a few modifications. The upper portions of the grille and fenders have been reworked to flow better into the hood and doors. In addition to the sleeker visuals, it should help improve aerodynamics. New headlights with three projectors are similar to those on the new Lexus LC sport coupe. The bottom portion of the bumper has been pulled forward a bit, making the NX look both less pointy and more like a small RX than ever. In the rear, the bumper is redesigned, adding in design elements that draw influence from the spindle grille. Like the headlights, the taillights have been updated with a shape that's similar to those on the LC. Other changes include reshaped exhaust tips, new 18-inch wheels, and a kick sensor that opens the rear hatch if you make a motion under the rear bumper. Like the exterior, the changes to the interior are small but notable. The infotainment screen has grown from 7 inches to 10.3 inches. The controls for both the infotainment and HVAC system have been updated. Nearly all of the control knobs and switches have what Lexus is calling a metallic satin finish, essentially a silver-gray looking matte coloring. Like with many other Toyota and Lexus products, the automaker's Lexus Safety System + now comes standard on all models. This includes emergency braking, radar cruise control, lane departure warnings, and automatic high beams. The turbocharged 2.0-liter inline four carries over unchanged, though the model is now known as the NX 300 (formerly the NX 200t). Likewise, the hybrid system in the NX 300h is unchanged. There have been some updates to the suspension, adding in a modified version of the adaptive variable suspension system from the LC. Lexus claims this should improve both ride and handling. No word on pricing or a release date, so look for more news some time in the next few months.

Lexus will bring production UX small crossover to Geneva

Lexus has announced it will show its upcoming UX crossover at the Geneva Motor Show next month. The new nameplate goes 0n a smallish crossover, designed to compete with the BMW X2, the Jaguar E-Pace, the Mercedes-Benz GLA and others. Some reports say the UX would be replacing the CT200h hatchback, which has been on the market since 2011. The manufacturer first used the name on a concept at the 2016 Paris Motor Show, and the shapes have now been worked into a production version. The Paris concept was certainly bulky and scifi-like, but then again, so is the Toyota C-HR on which the UX is reportedly based. Lexus trademarked the model names UX 200, UX 250 and UX 250h with the U.S. Patent and Trademark office way back in 2016, so expect those to reflect the powerplants on offer; the 250h stands for a hybrid version, as has become the norm. The UX's production version might also bear a similarly over-the-top spindle grille as on the LF-1 Limitless concept, which will also be shown at Geneva for its European premiere. The teaser image released by Lexus shows little more than a full-width taillight panel that takes a curious upturn at each end, and much of the crossover is still veiled by darkness. We'll see if any more teasers surface before the car's debut.
