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.

Mazda2 successor to ride atop shortened CX-5 platform

Mazda, looking to make the most of its new, lightweight Skyactiv vehicle architecture, will allegedly use a version of the CX-5 crossover's platform to underpin its next-generation Mazda2 hatchback, according to a report from Just-Auto.com. Of course, the Mazda2 is a much smaller vehicle than its larger CUV stablemate, so some serious chopping will no doubt be in order when it comes time to engineer the replacement for the company's smallest hatch.
Currently, the CX-5 and the sleek new Mazda6 share many of the same platform components, and this architecture will already be scaled down to support the next-generation Mazda3 sedan and hatchback, which will debut later this year. Just-Auto.com states that all of Mazda's remaining front-wheel-drive vehicles will eventually switch to reworked versions of this Skyactiv platform, including the replacement for the larger CX-9 crossover.
Also of note, Mazda will reportedly be switching to shorter, four-year lifecycles for its vehicles. This means that the newly launched Mazda6 will be replaced for the 2016 calendar year, with a refresh coming sometime in 2014. That said, vehicles with platforms supplied by other automakers (like the upcoming MX-5 Miata replacement that will share its underpinnings with an Alfa Romeo product) will not necessarily follow this four-year rule.

2014 Mazda6 i-Eloop to net 40 mpg hwy, 28 mpg city

Even before Mazda unveiled the 2014 Mazda6, it had introduced its innovative, non-hybrid i-Eloop (Intelligent Energy Loop) brake regeneration system. This technology converts kinetic energy into usable electricity using the alternator, a DC/DC converter and a capacitor mounted just behind the front fascia. During deceleration, the alternator captures energy that is then stored in the capacitor, which can later be used to directly power electric devices like climate control and audio systems. When i-Eloop power is used, it reduces the load on the engine and helps to conserve fuel.
Now available on the Mazda6, i-Eloop is only available on the $29,695 Grand Touring trim level as a part of the $2,080 GT Technology Package, meaning that buyers desiring i-Eloop will have to spend at least $31,775 (not including destination). The added price of this technology should be worth it for those looking for optimal fuel economy as the i-Eloop, combined with the package's active grille shutters, will bump the sedan's fuel economy numbers up to 28 miles per gallon city and 40 mpg highway - both are improvements of 2 mpg over the standard Mazda6 Grand Touring. The GT Technology Package also includes a Sport mode, lane departure warning, high beam control, radar cruise control and forward obstruction warning - the latter two technologies are currently offered in a $900 package that is being discontinued.
i-Eloop will eventually be offered on other Mazda products including the 2014 Mazda3. Scroll down for the official press release on the Mazda6's fuel-saving i-Eloop technology.
