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.

Mazda2 with extended-range hybrid rotary tech shown

Every story dealing with a new rotary engine from Mazda lands in a different place on the matrix of possibilities between "Coming soon!" and "Never gonna happen!" In 2011 it was speculated that the rotary engineering program would be shut down with the demise of the RX-8, in 2012 the program was still alive and taking lessons from the SkyActiv engines, in August 2013 a Mazda insider said a rotary engine called 16X would be here in two years, in November the CEO said the only way we'd ever get a new rotary is if Mazda could sell 100,000 of them per year. Meaning that, for the moment, you can forget about it.
And yet, last month Mazda was putting journalists in a Mazda2 RE Range Extender, an electric car using a 0.33-liter rotary to power its lithium-ion batteries when the charge runs down. With a 75-kilowatt, 100-horsepower electric motor turning the front wheels, the Wankel generator and its 2.6-gallon gas tank living under the trunk double the range of the electric-only Mazda2 to 250 miles.
There's been talk of using a rotary to assist an alt-fuel vehicle for at least seven years, with Mazda pairing an electric motor with a rotary that ran on gas and hydrogen in a Mazda5 in 2007. Since then, almost all of those stories debating its return or demise also spoke of the oddball motor's advantages, such as compact size and ability to run on various fuels, as an aid in an unconventional powertrain.

Mazda and Clemson collaborate on Deep Orange 3 concept

There are school projects, and then there's the Mazda Deep Orange 3 Concept Car, a one-off built by Clemson University automotive engineering students and designed by Frederick Naaman from the Art Center College of Design in Pasadena. Clemson students unveiled the chassis at the 2012 SEMA show in Las Vegas, although this is the first showing of the car fully clothed.
Sporting a unique hybrid powertrain that can automatically switch between front-, rear-, and all-wheel drive. A gas-powered engine handles the fronts, while the rears are powered by an electric motor and a battery pack. The Deep Orange 3 also has an unusual three-plus-three layout, making it a much cooler version of your parent's old Vista Cruiser. The exterior sheetmetal clearly follows Mazda's established design language, and looks like it could easily pass for a five-door version of the Shinari Concept. It really is a great looking vehicle.
The Deep Orange 3 was part of Clemson's graduate-level auto engineering program, and is a regular partnership between the east coast school and the Pasadena-based design college's students. Clemson, Art Center and Mazda will be showing the Deep Orange 3 at the Center for Automotive Research Management Briefing Seminars in Traverse City, MI, from August 5 to August 8.
