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 i-ROAD leans its way into the city [w/video]

According to Toyota, the "i-ROAD takes the company closer to its goal of creating the ultimate range of eco cars." As you're surely aware, that range of eco cars includes the enormously successful Prius family, but this new machine is nothing like the hybrid hatchback. And it's not even a car - Toyota calls the i-ROAD a Personal Mobility Vehicle.
Toyota's i-ROAD Concept, which debuts at this week's Geneva Motor Show, is adorned with just three wheels, meaning it's just as much a motorcycle as it is a car, and the driver and passenger sit in tandem style instead of side-by-side. This arrangement allows for a very thin 850mm width, which is about the same as a large motorcycle. Because the cockpit is enclosed, the occupants don't need helmets, nor are they open to the elements outside.
Also like a traditional two-wheeler, the i-ROAD tilts through the turns and when driving on uneven surfaces. Toyota says its computer-controlled Active Lean technology automatically balances the vehicle with no input from the driver.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
