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.

Weekly Recap: Things you might not know about the 2015 Dodge Charger and Challenger Hellcats

If you're an enthusiast, and you don't know that Dodge spawned another Hellcat this week, you really must have been living in cave. The 2015 Dodge Charger SRT Hellcat is probably the biggest news for enthusiasts since the reveal of, well the 2015 Dodge Challenger SRT Hellcat.
But, there are some things you might not know or might have missed about the new Charger and Challenger Hellcats. For starters, reports that the Hellcat production would be limited to a low volume are not true.
"We have not capped the Hellcat on either the Challenger or the Charger," Dodge CEO Tim Kuniskis said.

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.
