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.

A replacement for the Lexus CT 200h is due to arrive in 2021

On the hunt for a reasonably priced gas-electric hybrid-powered compact, but want something a little nicer than the oddity that is the Toyota Prius? You probably remembered that Lexus made the CT 200h. That's made, as in the Prius platform mate was discontinued in 2017. But word on the street is that Lexus is working on a replacement, according to Autocar in the UK. The outlet spoke to Lexus Europe's head honcho, Pascal Ruch, at the Geneva Motor Show recently, who shed some light on the matter. According to the report, a new CT 200h is set to arrive sometime in 2021 and will be built on Toyota's latest TNGA (Toyota New Global Architecture) modular platform. TNGA these days underpins a majority of Toyota's current models, from the new Camry, to the new Corolla, the current Prius, and even the new RAV4 and Highlander. But what isn't so clear is whether the CT 200h will keep its hatchback body style. A few years ago, we even heard the CT 200h could be replaced by a hybrid crossover. But nothing's confirmed. The original CT 200h used Toyota's old "New MC Platform." When new at the time, it underpinned many models from the third-generation Toyota Prius and Prius V, to the last Scion tC, Scion xB, the outgoing Toyota Corolla, the previous Toyota RAV4, and many other JDM-specification Toyota models. The CT 200h also pretty much utilized the same 1.8-liter 2ZR-FXE inline-four and electric motor hybrid powertrain as the Prius. It also produced the same total 134 horsepower and 153 pound-feet of torque. Despite being discontinued in the U.S. two years ago, Lexus continued with the CT 200h in Europe, where it sold, but modestly. And despite not being too hot of a seller here stateside as well, Lexus is adamant about keeping it in the portfolio as the automaker continues to push for more fuel-efficient hybrid models. Over the long-term, Lexus plan hopes to boost its global market share of hybrids to 50%. "Europe has a great strategic importance for Lexus because it's seen as a leading region for technology and design," Ruch told Autocar in its interview. "Our hybrid sales are highest in Europe, China and Japan will electrify [internal combustion engines] and the wider U.S.

Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."
