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.

Weekly Recap: Toyota, Mazda team up to 'make cars better'

Toyota and Mazda are teaming for a noble purpose: to "make cars better." That's how the two Japanese automakers termed their partnership, which was announced this week. So what does this actually mean? The companies said they will set up a joint committee to look for areas of cooperation and named safety and the environment as issues they plan to tackle. From a product perspective, it's believed that Toyota is interested in Mazda's Skyactive engine portfolio. In turn, Mazda has its eye on Toyota's fuel-cell and plug-in hybrid technology. While more specifics were not confirmed, the companies said the "agreement will go beyond the traditional framework of cooperation," and it has the potential to be a long-range partnership. "The main purpose of this initiative is to enhance the appeal of our cars," Toyota president Akio Toyoda said at the announcement. Previously, Mazda has licensed Toyota's hybrid tech and assembled compact cars for Toyota in Mexico. Akio Toyoda said these projects "triggered" the automakers to explore further collaboration. Dave Sullivan, product analysis manager for AutoPacific, said the tie-up echoes Daimler's wide-ranging work with the Renault-Nissan alliance. "This could be a well-groomed match due to each having very unique skill sets," he said. OTHER NEWS & NOTES Volvo selects South Carolina for US factory Volvo confirmed this week that it will build its first US factory in South Carolina, with construction set to begin this fall. The company first revealed plans in March, though it didn't announce a site. The plant will have initial annual production of 100,000 units, though the vehicle or vehicles to be assembled were not specified. The factory, located near Charleston, will open in 2018 and ultimately employ 4,000 people. The facility will help Volvo continue its growth strategy, which includes strengthening its presence in the US market, where it wants to sell more than 100,000 cars per year. "Building a plant in the US is a reflection of Volvo Cars' commitment to the US and the key role the US plays in our growth objectives," Lex Kerssemakers, senior vice president, Americas, said in a statement. Ford GT spied on the road The 2017 Ford GT was spotted testing around the Blue Oval's headquarters in Dearborn, MI, this week. The raw body panels were exposed, and they lacked paint or camouflage. It's the first time the GT has been captured on the street after a spring of auto show reveals.

Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.
