Mazda details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

Rumored Mazda CX-3 may not be for US

Mazda has used its Kodo design language to make some of the most attractive, affordable cars in the world right now, with the Mazda3, Mazda6 and CX-5 (pictured above), but it still lacks a crossover in the smaller class, which are becoming popular on the world market. It seems like a natural fit then, that the Japanese company would shrink its CUV design even smaller for a CX-3 to fill the gap. However, a rumor suggests that the compact might not make it to these shores.
The Mazda2-based crossover is due later this summer in Japan and is launching in Europe and emerging markets later, according to Automotive News citing a report in Japan's Nikkei newspaper. The little CUV would cost between 1.5 million yen and 2.0 million yen ($14,700-$19,500) in Japan and be available with diesel and petrol engine options. However, the report made no mention of selling it in North America. There is a glimmer of a chance for the CX-3 here. Mazda is upgrading its Mexican factory to 230,000 annual unit capacity by 2016, which gives it the room to add the new vehicle.
While the midsize CUVs are hugely popular in the US, compacts like the Buick Encore are still a small portion of things. If Mazda could time the CX-3's launch right here, it could take advantage of the lack of competition.

Mazda and Fiat finalize deal for Alfa roadster, next-gen MX-5 Miata

Although a little bit later than expected, Mazda and Fiat have signed a final agreement that will bring a next-generation MX-5 Miata to the Japanese automaker and a new roadster to Alfa Romeo. When the proposed arrangement was announced back in May, the two automakers had hoped to seal the deal last year, but it doesn't appear that the production timeline for these cars has slipped any, with both expected to start rolling off assembly lines in 2015.
Other than a shared chassis with a rear-wheel-drive layout, it sounds like the two cars are still planned to be distinct in their own ways from their styling right down to their engines. Mazda will produce both cars at a plant in Hiroshima, Japan, but it isn't clear what role each automaker will play in the cars' developmental process. The big question, of course, is what clever portmanteau name we can come up with, like Toyobaru. Mazda Romeo is the easy choice, but Alfazda might roll off the tongue a little better.
