Mazda returning to top-tier racing with diesel-powered prototype in USCC

Mazda has unveiled its latest challenger in the top flight of endurance racing, a diesel-powered prototype that will campaign the inaugural, 2014 Tudor United SportsCar Championship. The new Skyactiv-D-powered car will make its race debut at January's Rolex 24 at Daytona.
"This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991," said the director of Mazda Motorsports, John Doonan. That historic racecar, the rotary-powered 787B, has grown to become one of Mazda's many, well-known racers.
More recently, the Japanese brand has been making waves in the Grand-Am series, campaigning RX-8s and, most recently, running diesel-powered Mazda6 sedans in the GX-class. Mazda will campaign two factory-backed prototypes at Daytona. Driver lineups will be announced closer to race day.

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.

Mazda just restored the 787B's forgotten older brother

Among Mazda's many racecars, none is as famous as the 787B, and for good reason. The 787B remains the only Japanese car and the only rotary-powered car to win overall at the 24 Hours of Le Mans. It wasn't Mazda's only successful endurance racer, though. Before the 787B, there was the 767B. Mazda's 767B racecars competed in the IMSA GTP class at endurance races throughout 1989. They featured 630-horsepower four-rotor engines and were very successful in their class. This newly restored car took first and second place class finishes in five of the six races it participated in, and each finish was in the overall top ten. The one exception was a DNF in which the transmission failed. Twenty-five years after the 767B's glory days, Mazda initiated a complete teardown and restoration of the aged car. The work was done by Downing Atlanta and supervised by former Mazda racers Rick Engman and Jim Downing. (Fun fact: Downing was one of the designers of the HANS device.) The shop has also restored other racecars for Mazda, including one of the 787Bs. The car went through a two-year rehab and will make its track re-debut at the Monterey Motorsports Reunion. The event takes place next weekend at Mazda Raceway Laguna Seca where the track will once again feature the angry shriek of a competition-grade rotary engine.
