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.

Does the Toyota Prius still matter?

Toyota remains incredibly proud of its green halo car, the Prius. On the company website, it calls the gas-electric car, "The hybrid that started it all." Chances are, if someone tells you to think of a hybrid car today, your first thought is going to be the Prius. Now a cultural icon, the Prius changed a lot of attitudes about what an efficient car is able to achieve. But the car is aging, despite numerous refreshes and model tweaks over the years, and sales dropped 11.5 percent last year. It's taken Toyota 25 years of ups and downs to get the Prius to where it is today, and we started wondering if that's too long for the car to remain viable in an era of 40+ mile-per-gallon non-hybrid cars and a plethora of plug-in competitors for the green car crown (we're not the only ones). Plus, Toyota is rapidly shifting its green focus away from the Prius and towards the hydrogen-powered Mirai fuel cell car. But if you ask Toyota representatives if the Prius is still a vital car in 2015 – and we did – you'll find that there's still a lot of love for the car that went before. For example, Geri Yoza is a Toyota national manager who spent years traveling all across the US teaching people about the Prius. The veteran of countless customer education sessions told AutoblogGreen that it took a long time for the Prius to "cross the technology chasm," and that it wasn't until about a decade after launch that the car became a common sight outside of the initial popularity hotspots. "It takes a while for people to become confident in the technology, to understand that it's been proven," she said. Now that the hybrid is ensconced in the public mind, it's time for the next step. "I think the Prius, the whole idea 'to go before,' was to go before the Mirai." Part of that precursor status is due to the fact that a lot of the Prius' powertrain technology has made the jump to the Mirai. When we asked Bob Carter, Toyota's senior vice president of automotive operations, if the Prius still matters, he had a clear answer: "My goodness, yes." "We've been selling hybrids for 25 years," he said, "but when you go back, we had said that the Prius and hybrid technology were a bridge to the future and we were very clear that it's going to be a very long bridge. Essentially, and I'm not an engineer, the Mirai takes the technology from the Prius and takes the ICE engine out and puts a fuel cell stack in.

Subaru BRZ next generation will be sold in U.S. but maybe nowhere else

A new reports says that Subaru has "no plans" to launch its upcoming second-generation BRZ in Europe. If true, that means the 100-unit Final Edition announced earlier this year for the German market is truly the final edition for the Old World. Furthermore, according to the UK's Autocar, which reported the news, the BRZ "will be a U.S.-only model." That would indicate that even Subaru's home market of Japan would be denied access to the lightweight sports coupe, which seems unlikely. Toyota has been very tight-lipped about its own 86 version, so it's not clear which markets the BRZ's twin would be sold in. Though the article doesn't say why the BRZ won't be available in Europe, the Toyota 86 and Supra's chief engineer Tetsuya Tada may have given a clue. In a 2019 interview at the Supra's U.S. launch, he revealed that one reason he partnered with BMW was because he wanted the Supra to be a truly global sports car. Given the rapid tightening of safety and emissions regulations in various markets around the world, if Toyota were to have built its own engines and platforms from scratch, development would have taken too long. "If we had gone that route, the car would not be done, even today [in May 2019]. It wouldn’t be out for at least a few more years. The problem is, you canÂ’t sell a car like I showed you today in 2021." It looks like that may have been a prescient move. The BRZ is presumed to share a 2.4-liter boxer four with the Ascent and 2020 Outback, neither of which is sold in Europe. It's predicted to have 220 horsepower and retain its rear-wheel-drive layout. Sadly, it looks as if the Supra will be Toyota's last global sports car model. The 2021 BRZ will be revealed November 18.
