Toyota GR GT3 Concept: a long, lean racer with road aspirations

Toyota and Lexus trundled into the 2022 Tokyo Auto Salon with a bundle of modded gear. There are two especially racy bits — one, the GRMN Yaris we've already covered, and this, the Gazoo Racing GT3 Concept that is philosophically, if not aesthetically, related to the Yaris. Toyota believes it can provide more enjoyment for customers by commercializing race cars than by making customer cars racy. So instead of turning one of its road cars into a GT3-class competitor (Toyota does sell a Supra GT4), the GT3 Concept could be a customer potential race car that, as required by GT3 homologation rules, would become a road car.   Toyota Gazoo Racing President Koji Sato said the competition division will make a prototype GR GT3 at some point this year. That doesn't mean the exercise will go beyond this one-off, but Gazoo did also say, "TGR intends to use feedback and technologies refined through participation in various motorsports activities to develop both GT3 and mass-production cars and further promote making ever-better motorsports-bred cars," so its seems we will feel the effects of this somewhere. Based on the form factor of long, low hood and truncated, sloping rear, we could draw a line from the GR GT3 Concept to the Lexus Electrified Sport concept the luxury arm showed in December. Inspired by the LFA, that road car concept was claimed to hit 60 mph in the low 2-second range and be able to run about 435 miles on a charge. But we think it makes a lot more sense to draw a line from the GR GT3 Concept to Mazda's RX Vision GT3 concept from March 2020. We're not accusing GR of copying, but Toyota and Mazda are tight, and these two concepts could be confused for different skins on the same chassis in a video game. We'd be happy to see both make it to GT3 competition as it means there'd be street-legal versions, and frankly, this is probably a better path from circuit to street than the LMDh endurance racing hypercar that Gazoo Racing has toyed with turning into a street-going customer option. Elsewhere on the carmaker's Tokyo Auto Show stand, there was a racy on-road concept from Toyota and two off-road focused concepts from Lexus. The Toyota bZ4X GR Sport Concept turns the battery-electric crossover into a Friday L.A. nightclub hopper with a matte black exterior on big wheels in low-profile tires, and sport seats inside.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Toyota Yaris Hybrid-R zips in on its way to Frankfurt

Toyota has been known to make some exciting cars over the years, but its hybrids, well... let's just say a Prius appeals to a different kind of buyer. The TS030 Hybrid LMP1, on the other hand, now that's more our speed. And at the Frankfurt Motor Show next week, the Japanese industrial giant will bridge the gap with the concept car you see here. Previewed in bits and pieces along the way, Toyota has now revealed the full details and array of photos of its new Yaris Hybrid-R concept. And what the full picture reveals is a Prius C that's gone to the gym - or more appropriately, the track.
Powering this little pocket rocket is TMG's Global Racing Engine: a 1.6-liter inline-four with direct injection and a Garett turbocharger to drive 300 horsepower to the front wheels through a six-speed sequential gearbox. A pair of electric motors provide an extra 60 hp to each of the rear wheels for a combined output of 420 hp and through-the-road all-wheel drive. A third 60hp electric motor serves as traction control under acceleration and acts as a generator under braking to feed the TS030-derived super capacitor that boasts a higher power density and faster charge/discharge speed than a traditional battery. The system can provide a 40-horse boost for ten seconds in Road mode, or the full 120hp for five seconds in Track mode.
Though based on the three-door Yaris, there'd be no mistaking this for any ordinary econo-hatch. 18-inch TRD alloys with Michelin Pilot Sport Cup tires pack the wheel wells and a wider grille dominates the front fascia, while black and blue trim contrast sharply with the white bodywork. The rear pillar incorporates a quick-fill competition-spec fuel cap, LED daytime running lights illuminate the way and oversized brakes keep it all under control. The interior boasts Recaro racing buckets in black leather and blue Alcantara. There's more to digest in the press release below, but the bottom line is that if this is where Toyota is taking its hybrids, we want to climb into the driver's seat, and we're looking forward to seeing the concept in the flesh next week.
