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.

Toyota recalls 690,000 Tacoma trucks for rusty leaf springs, fire risk

Toyota has announced that it will be issuing a recall of 690,000 Tacoma pickups from model years 2005 through 2011. The affected vehicles include both the four-wheel-drive model and the two-wheel-drive PreRunner (but not the standard 4x2 pickups), which may have a rather serious problem with their rear suspensions.
In some cases, corrosion and stress could cause one of the three or four leaves in the rear suspension's leaf springs to fracture. While the trucks can still be driven with a broken leaf, Toyota is concerned that it could move out of position and impact other components in the rear of the truck, with a particular focus on the fuel tank. Needless to say, but a piece of metal continuously impacting anything, let alone the fuel tank, is cause for concern.
As of this writing, there have been no reports of crashes, injuries, fires or deaths due to this problem, although that won't stop Toyota from informing all affected customers of the issue. Those 690,000 owners will need to report in to dealers for inspections and, if necessary, repairs.

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.
