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.

Sports 800 is a progenitor of Toyota performance

There's an automotive axiom that claims it's more fun to drive a slow car fast, than a fast car slow. If that's the case, then pushing a Toyota Sports 800 around must be one of the most exhilarating experiences behind the wheel in the world. With just 800cc of displacement from a two-cylinder boxer engine, the focus is on finesse over outright speed. Still, it's a fantastic page in Toyota's performance history, and Petrolicious takes a ride with a man who owns a meticulously restored 1967 example in its latest video.
The Sports 800 used the classic cost-saving strategy in the auto industry of taking parts from a standard model in the lineup and modifying it into a sports car. In this case that meant borrowing the engine from the plebian Toyota Publica, beefing it up for more power and clothing the whole thing a in beautifully shaped, wind-tunnel-honed body.
The look of these lithe, targa roadsters is the exact opposite of the rather dull styling sometimes associated with Toyota today. Everywhere you look there are louvers, vents or curves to draw the eye. Check out the latest Petrolicious video for a detailed look at the history of this rare model that's largely unknown on this side of the Pacific.

Toyota and Mazda set to expand partnership

Toyota and Mazda are already teaming up for the Scion iA and Mazda2, but that partnership might just be the beginning. Reuters reports the two Japanese companies could expand their work together, with Toyota chipping in its experience with both fuel cells and plug-in-hybrid tech, and Mazda contributing its know-how in regards to its Skyactiv line of engines. The report cites a pair of unnamed sources that are "not authorized to discuss the matter publicly." The move, on the surface, is certainly appealing for both parties. Mazda has very little experience with hybrids (remember the Ford-rebadged Tribute Hybrid?), let alone something as advanced as a fuel-cell vehicle. Teaming with Toyota, arguably the world's greatest hybrid manufacturer, would give it a serious leg up. For the Japanese giant, meanwhile, a partnership with Mazda could expand the economy of scale for the Mirai FCV's tech, while Skyactiv engines would do well in replacing the base engines in cars like the Corolla, Camry, and RAV4.
