Driving classic Mazdas to experience the weird and wonderful rotary's triumph

AUGSBURG, Germany — Everything weird and wonderful about Mazda's relationship with the Wankel rotary engine is embodied in the delightful 110S Cosmo Sport of 1967. Just shy of 1,200 were built and, for most of its life, it remained a Japanese curio. Driving one is a rare privilege, and yet here I am, leading a convoy of owners through Bavaria away from a private museum holding the most extensive collection of Mazdas outside of Japan. Created by local franchise holder Walter Frey, what started out as a business relationship in the 1970s has blossomed into a lifetime love affair. Whether the residents of Augsburg are quite so enamoured is another question. As I leave the museum I pass a sign proclaiming my entry into an "umwelt zone" for low-emissions vehicles. The oil-tinged plume of smoke in my wake rather makes a mockery and underlines one reason there are no rotary engines in the current Mazda product range. Created by a German but perfected by the Japanese, it seems appropriate to celebrate the association with the Wankel engine here. Mazda may have gone on to sell nearly 2 million rotary-engined cars to the world — the U.S. included — but 50 years ago it brought two Cosmos to the Nurburgring and entered them into the grueling Marathon de la Route as a proof of concept. After 84 hours of continuous running and a fourth-place overall finish, Mazda had demonstrated to the world a rotary could stay the distance. I have a slightly less grueling schedule but look forward to following the instructions to rev the hell out of the Cosmo to clear the smoke out of its system. Those following me will certainly be hoping this does the trick. A thirst for oil as well as gasoline isn't the only rotary trait. The two chambers of its motor displace 491 cc apiece, equivalent to about 2.0 liters in a regular reciprocating design. In this second-series car, it delivers around 128 horsepower, which drives the rear wheels through the transmission's five gears. There doesn't seem to be a whole lot of progress in any of them, truth be told, the characteristic lack of torque making for more noise than meaningful acceleration. It's a small car and weighs just more than 2,000 pounds, with a power-to-weight ratio not far off that of an original NA Miata. But it's one for carrying speed, not building it. The wood-rimmed Nardi wheel is one piece of luxury in an otherwise functional, vinyl-trimmed cabin, and through it the Cosmo has a nice blend of stability and agility.

Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.

Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.
