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.

Mazda shows lightweight MX-5 Spyder and Speedster at SEMA

Ever since Mazda dropped the first teaser on us last week, we've been looking forward to seeing what it had in store for us at SEMA this year. Now we've seen it what Mazda has dubbed the MX-5 Spyder and MX-5 Speedster, and they were worth the wait. The Spyder goes vintage with a silver paintjob and a brown top stretched overhead. It also has an aero kit, grille, and tonneau cover done up in carbon fiber, rides on 17-inch wheels, and features a natural leather interior. The blue Speedster, meanwhile, goes for the stripped-down, wind-in-your-hair experience. It has no roof or windshield, just a tiny deflector at the front of the dashboard. It's dropped an inch closer to the ground on an adjustable coilover suspension with 16-inch alloys, and features a center-exit exhaust. Carbon fiber helps trim 250 pounds from the curb weight, along with a stripped out interior trimmed in Alcantara. Both look pretty slick, and disappoint only in so far as they (like so many of their predecessor concepts) won't be heading for production. If they were, we'd be hard pressed to choose between the two. Which would you go for? Mazda Reveals Extreme Lightweight Design Concepts at 2015 SEMA MX-5 Concepts Display Two Different Takes on Staying True to Pure, Lightweight Sports Car Philosophy LAS VEGAS (November 3, 2015) – Mazda revealed two design concepts today at the SEMA Show in Las Vegas, based on its all-new 2016 MX-5 Miata—MX-5 Spyder and MX-5 Speedster—demonstrating two vastly different takes on lightweight, open-air performance. Lightweight. Fun-to-drive. Roadster. Those three tenets have served as the foundation for the Mazda MX-5 Miata since its 1989 introduction and continue to serve the new fourth-generation model. Focused, lightweight engineering is a guiding principle of every Mazda vehicle made with SKYACTIV Technology, allowing for greater efficiency, improved performance and agile handling dynamics. But what if that sense of lightweight performance were taken to the extreme? What if Mazda's North American designers harkened back to vintage roadsters to create thoroughly modern, bespoke concepts for what a lightweight performance car should be The results would be the MX-5 Spyder and MX-5 Speedster concepts. "Both MX-5 Spyder and MX-5 Speedster are uncompromising designs that highlight the core strengths of MX-5," said Ken Saward, design manager, Mazda North American Operations.

1993 Mazda RX-7 Retro Review | A '90s hero turns 25

Boom times build interesting cars. In the late 1980s, Japan was flush with capital, and automakers spent like the party was never going to end. Suddenly building the third-generation RX-7 — the world's most advanced twin-turbo rotary sports car — seemed like the most natural thing a small car company hailing from Hiroshima could do. On this side of the Pacific, however, there was no context for the sudden influx of unusually tricked-out Japanese hardware flooding American dealerships. And none of the Japanese sports cars of the era was more unusual than the FD-generation Mazda RX-7, imported from 1993 to 1995 (and continuing on in Japan until 2002). Although the island nation's economy was headed on a downward spiral by the end of 1990, Mazda was in no position to pull back and walk away from the development dollars that had already been spent on its latest RX-7. As a result, Americans were able to briefly bask in the glow of one of the most unique engineering experiments ever unleashed on unsuspecting buyers. For its time, the Mazda RX-7 was a spaceship. With fluid lines that screamed "exotic," it joined the NSX in showing that supercars didn't have to have European blue blood running in their cooling systems to elegantly snag eyeballs. The twin-rotor, 1.3-liter 13B-REW situated behind the RX-7's front axle revved all the way to 8,000 rpm on its quest to produce 255 horsepower and 217 pound-feet of torque, with a pair of sequential turbos handing boost duties back and forth around the 4,500 rpm mark. A five-speed manual gearbox was standard with the FD (a four-speed automatic was optional), as was a curb weight in the neighborhood of 2,800 pounds — nearly 500 lbs less than the contemporary Toyota Supra. Significant figures for the era, to be sure. While they might pale in comparison to the average sports car today, slide into the RX-7's cockpit and drive the car, rather than just crunch the numbers. You'll quickly discover what can be accomplished when the company that engineered the Miata pulls a full John Hammond and "spares no expense" developing a world-beating sports car platform. The 1993 Mazda RX-7 I've been loaned from Mazda's classic collection is an R1 car, which means tighter suspension tuning, a few cosmetic upgrades, and a Competition Yellow paint job.
