Fourth-gen Mazda MX-5 Miata could get turbo power later in life

While there's a lot to love about the new Mazda MX-5 Miata, its debut was met by a vocal group of enthusiasts who derided the fourth-generation roadster's reduction in power output. The new model only puts out 155 horsepower, down from 167 in the NC. A report from Australia, though, claims Mazda may yet address the less potent output of the ND. Things started earlier this year, as Motoring.com.au tells it, when Mazda's global PR boss, Kudo Hidetoshi, hinted that a turbocharged or Mazdaspeed model "will definitely" be considered. Then last month at Goodwood, the ND's program manager, Nobuhiro Yamamoto, said complainers were welcome to get their thrills elsewhere. Recognizing this contradiction among Mazda's brass, Motoring asked Yamamoto-san again about his statements, which he seemed to walk back. "It's not a conflict [between statements made by Yamamoto and Hidetoshi]," Yamamoto said, indicating that his statements were made in relation to the new MX-5's launch. "Kudo-san talked about this in terms of a 10-year lifespan, but when I was asked the question right after the launching of the ND, I said 'we have no plan to have a turbo at that point in time.' That is what I meant." Seeking an opening, Motoring pushed the Japanese engineer on the chances of a more potent MX-5, perhaps without a turbocharger. "If you could achieve what we want, to which is great response, very light and powerful with great performance feel with natural aspiration, then we don't need a turbo," Yamamoto said. "But if we want more power because we don't get satisfied with natural aspiration then we may think about the turbo." Related Video:

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.
