Toyota drops detail about 414-hp Hybrid-R concept powertrain

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.

Toyota Tundra ditches V6 for 2015

The Toyota Tundra debuted in new-ish form for the 2014 model year, but as we head into 2015, the truck boasts a couple of small updates. Most notably, the base V6 engine has been discontinued. On top of that, there's the new TRD Pro model on offer for 2015, which we've told you about before.
Why kill the V6? Simple - it was very low-volume. "The Tundra V6 take rate was significantly less than five percent," a Toyota spokesperson confirmed via email to Autoblog. So for 2015, the two V8 engine options remain - a 4.6-liter unit with 310 horsepower and 327 pound-feet of torque, or the more powerful 5.7-liter powerplant with 381 hp and 401 lb-ft. Both engines are mated to a six-speed automatic transmission, and rear-wheel drive is standard. Four-wheel drive, of course, is available with either engine.
The only other noteworthy changes for 2015 include an optional integrated trailer brake for the 5.7-liter models, a new rear under-seat tray storage system for Double Cab trucks, and a spray-in bed-liner. Scroll down for the official press blast.
