Toyota previews next Lexus RX with Tokyo-bound JDM Harrier

The Lexus RX shares much with the Toyota Highlander, but its more direct counterpart is the Toyota Harrrier. Never heard of it? That's because Toyota only sells it at home in Japan, and now it's revealed a new one. So if the Harrier is essentially a Toyota-badged version of the RX, then what's the big deal, you ask? The big deal is that the new Harrier which leaked in July, set to debut at the Tokyo Motor Show next week and which you see here isn't quite the same as the Lexus, and those differences could (and in most cases likely will) make their way over to the RX as well.
For starters, the styling is different. Granted that the Lexus version will almost certainly get a spindle-shaped grille, but even so, the Harrier's nose seems to protrude further than the RX's and the headlamps are a notably different shape. The greenhouse is also a different shape, coming to a sharper point at the back, and the mirrors are fixed to the A-pillar not to the door panel. The taillamps are revised, the tailgate has a new profile and there's a pseudo-diffuser at the bottom of the rear bumper. Subtle changes, to be sure, but then Toyota and Lexus are known for their evolutionary approach to styling. The interior has apparently undergone some updates as well, with a more dynamically styled dashboard, a more symmetrical center stack and different seats, steering wheel, door panels... the works. The infotainment display screen has also moved further down from its position in the current RX.
Toyota will offer the new Harrier with a 2.0-liter four mated to a CVT and driving either the front wheels or all four, and a hybrid setup with a 2.5-liter married to a 140-hp electric motor. The RX is offered here with a 3.5-liter V6 either on its own or with an electric assist. We wouldn't expect Lexus to go swapping the larger engines for the smaller ones, at least not for the US market. There's plenty more to the Harrier, of course, than the similarities and differences to the Lexus RX, and if you're buying a premium crossover in Japan, you can delve into the full details in the press release below, together with the images in the gallery above.

Junkyard Gem: 1992 Lexus SC 400

After Toyota stunned the automotive world with the Lexus LS 400 in 1989, offering a majestically engineered luxury sedan with an all-new DOHC V8 at less than half the cost of its Mercedes-Benz 560 SEL rival, what could be done to follow that (other than a money-printing Lexus-badged Camry, that is)? Clearly, the missing piece of the Lexus branding puzzle at the time was a sports coupe, something to extract the money of car shoppers considering, say, a new Mercedes-Benz 300 CE or Acura Legend coupe. That car turned out to be the Lexus SC, styled in California and known as the third-generation Toyota Soarer in Japan. Here's one of the very first SCs sold in the United States, found in a Denver-area self-service yard last month. These cars had intimidatingly good build quality (I know, because I dismantled a '92 SC 400 down to its smallest components a while back), clearly designed to last at least a quarter-million miles with routine maintenance. This one got hit hard in the right rear, however, and it wasn't worth repairing the damage to a non-SUV pushing three decades of age. Americans could buy a six-cylinder version, the SC 300, which came standard with a five-speed manual transmission (almost all buyers "upgraded" to the automatic, of course). This car is the SC 400, which means it has the same 1UZ-FE V8 engine as the LS 400. That's 250 super-smooth horses and six-bolt main bearing caps keeping the crankshaft from going anywhere it shouldn't. The SC 400 never was available with a manual transmission, nor was its SC 430 successor. This one has the mandatory Aisin-Warner four-speed automatic. This content is hosted by a third party.

These cars were very quiet and comfortable and they could cruise all day at triple-digit speeds, but a curb weight pushing 3,600 pounds meant that the SC 400 wasn't going to beat its Porsche 928 rival on a race track. Actually, the 1992 928S4 cost more than twice as much as the 1992 Lexus SC 400 ($80,920 versus $37,500) and had both a more powerful (326hp) V8 and available manual transmission; perhaps the 1992 Cadillac Eldorado Touring Coupe ($32,470, 200hp V8, automatic) was a more realistic sales rival for today's Junkyard Gem.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.
