TMG's super Lexus LS Sports 650 gets track tested

The people at Toyota Motorsport GmbH have been responsible for the Japanese automaker's motorsports efforts since the 1970s, but since Toyota pulled out of Formula One after the 2009 season, the tuning shop has been developing a super sedan based on the Lexus LS called the Sports 650. Details on TMG's first road car have been scarce, but XCAR was recently invited to drive the 641-horsepower Lexus on track.
Here's what we know: the Sports 650 has enough power to sprint to 60 miles per hour in under four seconds, tops out at 199 mph, weighs over two tons and utilizes LFA brakes. Oh, and its twin-turbo V8 bellows like an AMG V8. That last part isn't surprising when considering TMG could become Toyota's in-house tuning arm - like AMG is to Mercedes-Benz. As for the bespoke body kit, fender flares and stacked exhaust pipes? They fit the car well and even remind us a bit of Lexus' other high-performance sedan, the IS F. Currently there are no plans for the Sports 650 to be made into a production car, but we doubt TMG is devoting this much effort developing the LS into a road-rocket for nothing.
Check out XCAR's video below to see the AMG-fighter wrung out on track, and then ponder what could be if TMG were let loose to fiddle with other cars in Lexus' lineup. Now that's something we could get used to!

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.

The techie choice | 2017 Toyota Prius Prime Quick Spin

The Prius nameplate has been inexorably tied to the green car scene for a long time now. When Toyota unleashed the Prius Prime upon the world, we said it was the best Prius yet. But this is no longer a world where Toyota's hybrids are automatically crowned king. Our recent time with the Hyundai Ioniq trio was a stark reminder that the economical, eco-conscious competition is getting stiffer. We put some miles on a Prius Prime to see how our recent Ioniq Plug-In Hybrid test colors our view of Toyota's prime contender. Our first impression: the Prius design is very clean and inorganic. As sterile as it feels, the design appears to have a lot of actual thought behind it. Our Advanced trim tester is spiritually in touch with the mobile gadget culture, with a huge touchscreen, digitization of seemingly everything, and white and black glossy plastic aesthetic. It's a tech-heavy design that will likely seem familiar to those of us who have been interfacing with Apple designs for the past 10 or so years. The Ioniq Plug-In Hybrid, on the other hand, remains truer to the look and feel most drivers expect from their commuters. It's less about user interface, modes, and drive data, and more about just getting behind the wheel and driving. The Ioniq Plug-In Hybrid hardly even distinguishes itself from its plugless counterparts, opting to go green under cover rather than the in-your-face futurism the Prius projects. It retains the traditional instrument cluster in front of the driver, too, which the Prius Prime lacks. In the Toyota, you'll have to look around the car for the right display with the information you're looking for – there's the huge central touchscreen with all its menus, as well as smaller displays above it on the dash – or you can find your speed on the HUD. The Prius is composed in its handling, but doesn't provide much of the sensory feedback that makes one feel connected to the chassis. The steering feels super artificial, but the car stays fairly flat in the corners without providing too much feedback through the seat of your pants. Hyundai's offering, though, proved to be a surprisingly willing dance partner in the corners. While feeling equally as capable as the Prius, the Ioniq's sense of connection through steering and suspension made the act of stitching one turn after another together enough to get our blood pumping. Sport mode makes the Prius Prime slightly livelier, though.
