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.

2024 Lexus GX and Land Rover Defender numbers crunched

The 2024 Lexus GX finally brings the luxury off-roader up-to-date. And it does so in a boxy, rugged wrapper that makes comparisons to the 2024 Land Rover Defender, another luxury off-roader of similar size and capability. So we figured, let's make that comparison. We've looked at all the specifications available for the two SUVs to see how they stack up. Engines and Transmissions The GX keeps things simple under the hood with a single powertrain. It has a twin-turbocharged 3.4-liter V6 hybrid making 340 horsepower and 479 pound-feet of torque. That horsepower number only tops the Defender's four-cylinder engine, but the GX has the torque advantage even against the Defender's mighty V8 option. The GX's V6 is paired with a 10-speed automatic and full-time four-wheel drive. Full fuel economy numbers haven't been given, but Toyota is expecting 17 mpg combined. Unfortunately, that fuel economy is worse than all the Defender powertrains except the V8. As alluded to, the Defender is available with three main engines, an inline-four, inline-six and V8. The closest competitors to the GX will be the regular 110 four-door and the longer 130 four-door. The 110 can be had with the turbo 2.0L four-cylinder making 296 horsepower and 295 pound-feet of torque; the turbo mild-hybrid 3.0L six-cylinder making 395 horsepower and 405 pound-feet; or the supercharged 5.0L V8 making 518 horsepower and 461 pound-feet. The 130 gets two versions of the six-cylinder, one making 296 horsepower and 347 pound-feet and one making 395 horsepower and 405 pound-feet. The V8 is also available but just with 493 horsepower and 461 pound-feet of torque. All of the engines get an eight-speed automatic and full-time four-wheel drive. The four-cylinder 110 gets 18 mpg combined, the six gets 20 and the V8 manages just 16. Both 130 six-cylinder powertrains return 19 mpg combined, and the V8 doesn't have numbers yet. Towing and Cargo Towing capacity is pretty straightforward. The Lexus has a maximum capacity of 8,000 pounds, and the Land Rover tops it by 200 pounds more. Some trim levels of both SUVs have lower towing capacity, depending on the configuration. As for cargo space, Lexus hasn't shared details. It is available with up to three rows of seating and room for seven passengers. The 110 has similar seating available, and the 130 ups the ante with a three-across third row. And we've found that the 130's third row is genuinely usable by adults.

Japanese earthquakes send ripples through auto industry

The earthquakes since April 14 in Japan's Kumamoto Prefecture on the island of Kyushu are having aftershocks on the US auto industry, particularly for Toyota. The company shut down most of its factories in the country due to parts shortages, and the plants will be closed at least through April 23. "Decisions regarding recommencement of operation at plants in Japan will be made on the basis of availability of parts," the company said in a statement. According to Automotive News, Toyota's closed factories include a vast range of popular models in the US, including the Toyota Prius, Mirai, RAV4, 4Runner, Land Cruiser, Lexus ES, LS, IS, GS, RC, NX, RX, GX, and LX. The company's only sites in Japan that are still open build Hino trucks, Daihatsu models, and the Toyota Century limo. Toyota isn't yet sure whether these shutdowns could lead to vehicle shortages in the US. "As you can imagine, we are still reviewing the situation and working to learn more," company spokesperson Aaron Fowles told Autoblog. "While we know that production will be suspended in stages at most of our vehicle assembly facilities in Japan between April 18th and the 23rd, we do not know if they will continue production suspensions. Also, any effects to our inventory and/or sales have yet to be determined." He expects the automaker to know more in the coming days. Many of the affected Toyota plants aren't even in Kumamoto Prefecture, but major suppliers have factories in the region. For example, Aisin Seiki and Renesas Electronics both had to shutdown operations at plants in the area, according to Automotive News. Toyota isn't the only automaker affected. Nissan experienced a brief slowdown but was back to work on Monday, and Honda has suspended a motorcycle plant in the region until Friday. Mitsubishi had to close a production line due to the parts shortage, according to The Japan Times, but it didn't affect US models. "A supplier to our Mizushima plant has been impacted but they only supply an engine part for our mini car line. That line has been temporarily shut down due to that situation," spokesperson Alex Fedorak told Autoblog. "That same plant builds the Lancer and i-MiEv and there has been no impact to that line and production continues uninterrupted." Two major quakes hit Kumamoto Prefecture around Kumamoto city in the past week. The first on April 14 measured 6.4 magnitude, and a second on April 16 measured 7.3.
