A new Toyota MR2? We want to believe

In the wake of a busy Geneva auto show, the rumor mill is churning, and the latest grist involves one of the most beloved Toyota sports cars of all time. EVO reports that Tetsuya Tada, the chief of the Scion FR-S/Toyota 86 project and a hard-liner about sportscar priorities (light and nimble, but with modest horsepower), wants a third vehicle for Toyota's nascent sporty lineup. Currently, we know there's a Supra-like vehicle in the works, being co-developed with BMW, and the 86 is sticking around. Tada said he'd like a third sportscar to compliment the two we know about, and that he wants it soon. A quick bit of history: Toyota's classic sporty lineup had three components. The most visible was the Supra, whose power and prestige grew as the car evolved from a cushy personal tourer to a high-horsepower, high-technology icon. The Celica was its Clark Kent, more mild mannered but also more accessible and affordable. The third was the MR2, a mid-engined go-kart that lasted for three distinct generations. Each had its charms, and all have their fans. When Tada says that he wants three sportscars in the lineup, we already know about the Supra successor, and the 86 is already filling the Celica's role, so the blank is easy to fill. It doesn't sound like Tada spoke the word "MR2" to EVO, or hinted that the car would be mid-engined, but Tada doesn't seem to say anything without purpose. Whatever the layout, this third car – if it comes to fruition – will probably play a role similar to the MR2 in relation to its stablemates. To translate: it'll likely be even lighter and more nimble, and probably less powerful, than the 86. The closest real-world analogue to the pure MR2 ideal is the Honda S660, a mid-engined Kei roadster that's on sale in Japan right now. It's light, small, and powered by a 0.66-liter inline-three. Toyota could decide to directly compete with the S660, borrow an engine from its small-car specialist subsidiary Daihatsu, and produce a mid-engined MR2. Another possibility, even simpler from Toyota's perspective, would be to adapt the existing Daihatsu Copen roadster. Sure, it's front-engine and front-wheel drive, but it's a small, light roadster. And even better, it sells abroad with a larger 1.3-liter engine. Restyle it slightly, perhaps to resemble the S-FR concept of a couple years ago, and it's an off-the-shelf solution. The S-FR itself is a third possibility.

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.

Kyle Busch breaks leg in big crash, will miss Daytona 500

NASCAR driver Kyle Busch suffered a compound fracture of the lower right leg and a mid-foot fracture of his left yesterday at Daytona during the 112th lap of the Alert Today Florida 300, the season-opening race of the 2015 NASCAR XFINITY Series. Busch came into contact with the infield wall just past the pit lane exit, an area where there is currently no SAFER barrier, which is designed to reduce the risk of injury in a crash. Fellow racer Ty Dillon, the third-place finisher in the race, expressed a common refrain following the news of Busch's injury. "I think we're to the point now in NASCAR we should have SAFER barriers at a place like this, we're going so fast. I think we could probably afford it," said Dillon. Matt Crafton will drive the No. 18 Toyota today at the Daytona 500 today as a substitute for Busch, but it's not yet clear if he will continue to drive the car following Daytona. Kurt Busch, Kyle's older brother, will also miss the Daytona 500 due to the domestic violence case against him in Delaware. Video footage of the wreck can be seen above. It goes without saying, but we wish Kyle a speedy recovery and a return to his stock car as quickly as possible.
