Filed under: Concept Cars , Frankfurt Motor Show , Hybrid , Technology , Hatchback , Toyota , Racing The Toyota Yaris Hybrid-R Concept has been teased already, offering up little glimpses and details of the Frankfurt -bound vehicle. And while those few, shadowy shots have been great, we’ve really wanted to know how this hatchback would deliver its promised 400-plus horsepower. Under hood sits a 1.6-liter, race-derived, direct-injection, turbocharged four-cylinder that powers the front wheels. Sounds peachy, but with 414 horsepower splashed across the page, we’re going to need something more than a 1.6-liter, turbo four. A supercapacitor, developed from the Toyota TS030 Hybrid Le Mans racer sits in place of a hybrid’s traditional battery packs. The benefit, according to Toyota , is that power can be more rapidly absorbed and discharged than in a traditional battery system, like nickel metal-hydride. The gas engine is joined by a trio of 60-horsepower electric motors. Two of the them power the rear wheels, while the third sits between the engine and the six-speed, sequential gearbox. Developing the same amount of power as the rear-axle motors, this centrally located motor channels power to the race-derived supercapacitor during braking, and ships extra grunt to the rear wheels under acceleration when the front wheels start to lose grip. Besides the distributive power of the central motor, the rear electric motors can adjust the amount of torque flowing to each wheel, much like a differential.

Filed under: Concept Cars , Frankfurt Motor Show , Hybrid , Performance , Hatchback , Toyota Toyota has undeniably carved out a niche for itself as the industry’s leader in hybrid propulsion. What started out with the original Prius in 1997 has, over the past sixteen years, ballooned to what Toyota reports as a global hybrid portfolio of 23 models. But few (if any of them) are particularly exciting. That’s where the Yaris Hybrid-R concept comes in. Set to be showcased along with the rest of Toyota’s hybrid and fuel-cell lineup at the upcoming Frankfurt Motor Show next month, the concept starts with one of the Japanese auto giant’s least exciting models and upgrades it to more enticing territory. Toyota Motorsport GmbH – the same Cologne, Germany-based division that operated the company’s F1 team, currently runs its Le Mans program and gave us that bonkers 650-horsepower Lexus LS – has slotted in a version of Toyota’s new 1.6-liter Global Race Engine and paired it with a couple of electric motors for hybrid propulsion and through-the-road all-wheel drive. Like the TS030 Hybrid LMP1 , the Yaris Hybrid-R concept uses a super capacitor (instead of a conventional battery) to store the regenerated brake energy and give it upwards of 400 horsepower. That’s about all Toyota is revealing at this point, but this is the first time it has confirmed the project is based on a Yaris, of all things, and the confirmation comes with the solitary teaser rendering you see above. Check out the press release after the jump and watch this space for more as Frankfurt fast approaches.
