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, PSA extend partnership with new European van

Toyota and PSA Peugeot Citroen collaborate on a number of vehicles. One of them is a small van jointly developed by the two automakers but marketed individually under their own brands across Europe. Now they've announced the extension of that collaboration, and revealed the first image and details of their new product. Set to be unveiled at their respective booths at the Geneva Motor Show this coming March are the new Toyota ProAce, Peugeot Traveller, and Citroen Spacetourer. They replace the Toyota model of the same name as well as the outgoing Peugeot Expert and Citroen Dispatch, and will each be made available in private and commercial shuttle forms. Although technical specifications have yet to be announced, each will share the same underpinnings and mechanical components, leaving only the parts you can see changing from one brand's version to the next. Expect engines to range from 1.5 to 2.0 liters and burning gasoline or diesel, but the latter will undoubtedly prove the more popular option in Europe. No mention was made of a replacement for the Fiat Scudo, another badge-engineered version of the same van program in its current form. That would seem to suggest that Fiat Professional is either preparing to go it alone with the next-generation Scudo, or phase out the model altogether. The current Scudo slots in between the smaller Doblo (imported to the US as the Ram ProMaster City) and the larger Ducato which was also jointly developed with PSA and sold as the Citroen Jumper/Relay, Peugeot Boxer, and here in America as the Ram ProMaster. The ProAce and its cousins are made by PSA at its Sevel plant in Valenciennes, France. Aside from their vans, the Japanese and French automakers also collaborate on the city car platform sold alternately as the Toyota Aygo, Peugeot 108, and Citroen C1. Fiat also partners with PSA on the smaller Fiat Fiorino/Qubo, Peugeot Bipper and Citroen Nemo. All of which just goes to show what a tangled web they weave in the European market, especially where commercial vehicles are concerned. NEW STAGE IN THE CO-OPERATION PROGRAM BETWEEN PSA PEUGEOT CITROEN AND TOYOTA PSA Peugeot Citroen and Toyota Motor Europe (TME) reveal today the new Citroen SPACETOURER, Peugeot TRAVELLER, and Toyota PROACE. They will be available in MPV versions for private use and in shuttle versions for business use. Both companies therefore confirm the continuation of their co-operation agreement signed in 2012.

Next Toyota Prius may get optional all-wheel drive

We've been hearing rumors about the next generation of the Toyota Prius for the last couple of years on a pretty regular basis. From the expectation of lithium-ion battery packs with more capacity for electric-only miles to wireless charging and more emotional styling, there's been no shortage of talking points for the car that's expected to see its first light of day at the very end of 2015 (we hope). But one thing we've yet to hear about, until now that is, is all-wheel drive. According to a report from Automotive News, Koei Saga, senior managing officer in charge of powertrain development of the Prius, said in an interview last week, "I think we will possibly do [all-wheel drive]" for the car's next generation. There isn't any further indication on how the AWD system would work, but we'd put our money on something similar, at least in principle, to the E-Four system that just debuted on the 2015 Lexus NX 300h, which uses an electric motor mounted at the rear to power the car's back wheels when the front wheels lose traction. The AN report also repeats a rumor we've heard before – that Toyota may offer two different battery pack options in its next Prius, one using lithium-ion chemistry and one using the nickel metal hydride technology that the Prius has featured from its very beginning. While the automaker has yet to talk efficiency, it's natural to expect more capacity for EV driving from newer lithium-based technology over that of nickel-based packs to go along with what we'd also expect would be a somewhat higher price. We're sure you're just as curious about the next Prius as much as we are, and so we'll leave you with these words, again from Saga: "The batteries will be renewed. Everything will be revised. And I think we will come up with a fuel economy that will surprise everyone."
