Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda Hot Lap Challenge will put simulator drivers in real Miatas

Using a video game as a feeder racing series is nothing new. Sony and Nissan have run the GT Academy for years now, rewarding the best Gran Turismo players with the chance to drive a real car. It seems Mazda wants a piece of the action. This year, it will host an iRacing Hot Lap Challenge, giving the best players a trip to the 2019 Rolex 24 at Daytona. The two fastest drivers will race head-to-head, with the winner earning a test drive in a Mazda MX-5 Miata Cup car. During 2018, Mazda will host events events at select races where participants can lap Daytona in an iRacing simulator. Those who can't attend one of those events will have the chance to compete on iRacing at home. At the end of the year, 35 drivers will compete for a trip to the 2019 race. That winner will be a guest of Mazda Team Joest. The event is open to U.S. residents age 18 and above. Full details can be found on the iRacing website. The event calendar is listed below. Online time attack schedule Week 1: 4/13 – 4/15 – Daytona Road Course Week 2: 5/25 – 5/26 – Lime Rock Park Week 3: 6/29 – 7/1 – Watkins Glen Week 4: 8/3 – 8/5 – Road America Week 5: 8/24 – 8/25 – Gateway Motorsports Park Week 6 9/7 – 9/9 – Laguna Seca Week 7: 10/11 – 10/13 – Road Atlanta TA sessions will be available the entire day(s) based on GMT At-track schedule Week 1: 4/13 – 4/15 – Long Beach Week 2: 5/25 – 5/26 – Lime Rock Park Week 3: 6/29 – 7/1 – Watkins Glen Week 4: 8/3 – 8/5 – Road America Week 5: 8/24 – 8/25 – Gateway Motorsports Park Week 6 9/7 – 9/9 – Laguna Seca Week 7: 10/11 – 10/13 – Road Atlanta Related Video: News Source: Mazda, iRacing Marketing/Advertising Toys/Games Mazda Convertible Racing Vehicles mazda mx-5 mazda mx-5 cup

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.
