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's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

We dialed a random Swede, talked about not driving Volvos

The Swedish Number is now a thing. It's a cool thing. You dial, a random Swede picks up, and you chat. Or, in my case, you dial and a random Brit living in Sweden for the past six year picks up and you chat. Since I was calling on behalf of Autoblog, when I got Martin from the small coastal town of Sundsvall, on the phone, we talked about cars, Volvos (natch), and cold-weather testing. Oh, and about plugging in his regular Toyota Prius. ABG: I was able to come to Sweden and test Volvos a month or so ago. Do you drive a Volvo? Martin: [laughs] No. I think Volvo is a fantastic car. It truly is an amazing car, but no. My girlfriend has a company car, so we drive a hybrid Toyota Prius. ABG: And how does that work in the cold winters? It obviously cuts down on the environmental problems. Martin: No problem at all. Because we have these cold winters, like you do get in the States as well, where we park our cars, we've got electricity posts where we can plug in the cars. Motor car engines have a heater, so you can have the heater going for some time before you get into the car. So it warms up the engine and there's a socket inside the car to warm up the inside of the car as well. It's very efficient. You just need to remember to set the timer when you climb out of the car and connect the cable. It obviously cuts down on the environmental problems as well because your car is already warm before you start them. ABG: I know that makes them overall more efficient, I just didn't know it could work with any car. It used to be you would keep the diesel engine blocks warm, but this works for pretty much any car in Sweden? Martin: Yes. Our temperatures here can vary. We do tend to get roundabout -18 to -25C [0 to -15F], where I live, sometimes. Normally, in the winter, we always plug the car in to make it more environmentally friendly, for starters, and then it's a nice warm car when you get in. The coldest I remember it getting here was -36 [-33F]. In the north of Sweden they've had, on record, -56 [-69F]. ABG: That's too cold. Martin: That is cold, yeah. Most countries, now, use the north of Sweden to test their cars because of the ice. Volvo S90 Prototype View 15 Photos ABG: That's actually why I came over there, to test out the new XC90s and S90s. Martin: Is that your job, then? ABG: I don't test the cars for the companies, but I test them for Autoblog. They'll invite us to test the vehicles so we can see for ourselves what the vehicles do in cold weather.
