Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.

Mazda recalling 88k vehicles for ECU glitch

Need a break from news about the General Motors ignition switch recall? This Mazda recall should serve as a nice change of pace. It involves 88,000 cars across the globe, and focuses on the brand's three most recent (and important) models - the Mazda3, Mazda6 and CX-5.
The issue rests with Mazda's new i-ELOOP regenerative braking system. Apparently there's a problem with the ECU program that monitors whether a capacitor in the regen system is working. Acceleration is affected, and in severe cases, the engine could stall. There have been no mention of accidents or injuries due to the issue, and the glitch itself can be cured by an ECU reflash.
As i-ELOOP is a fairly new system for Mazda, particularly in the US, the total number of affected models is rather low, with just 6,500 US cars affected. Europe is hit hardest, with 38,000 models while Mazda's home market of Japan adds 27,600 cars and crossovers. Affected models were built between October 2012 and January 2014.

Mazda doubles down with a pair of Threes

Looking to appeal to the compact tuner crowd, Mazda brought two different flavors of its 2014 Mazda3 to the SEMA Show in Las Vegas this week. The Club Sport 3 Concept hatchback (above) has more of a racing vibe to it, while the Vector 3 Concept sedan (right) looks to inject a little extra fashion into the all-new Mazda3.
Hotting up the 3, Mazda stuck with the stock 2.5-liter engine on the Club Sport 3 Concept but added a limited-slip differential and six-speed manual gearbox, the latter of which was lifted from the CX-5 crossover. Other upgrades include coil-over shocks, a performance exhaust, Brembo brakes and an aero body kit - the latter of which will be offered to buyers at a later date.
While the Vector 3 Concept does get some performance bits like two-piece Brembo brake rotors and grippier tires, the focus on this sedan is all about styling. Starting with a custom paint job and ghost stripes, the whole look is tied together with 19-inch, V-spoke Rays wheels.
