Mazda 767B crashes during Goodwood, suffers heavy damage [UPDATE]

Update: Autoblog has learned that the Mazda 767B wrecked at Goodwood was being driven by Seniji Hoshino. He was not seriously harmed and was able to walk away from the crash. Hoshino's car was chassis 001 and scored a win in the GTP class of the 1989 24 Hours of Le Mans. A Mazda 767B Group C racer suffered a crash the Goodwood Festival of Speed that tore off the rear wing and did some fairly serious looking front end damage. According to Jalopnik, the racer was taking a timed run during the event's famous hillclimb when it went into the hay bales. The driver is reportedly okay, though. We've reached out to Mazda and Goodwood sources to identify the pilot in question, with no luck so far. Look for an updated post later in the day if we get any answers on that front. Images of the sad wreck seem to be populating on Twitter feeds as we write this. The racing Mazda clearly suffered a big hit today; painful to look at even after the fact. But we're not sure if the damage is beyond the abilities of skilled factory workmen to fix. Our collective fingers are crossed. Mazda has a major presence at Goodwood this year, including the event's art installation. Among all of its vehicles, there are two privately owned 767Bs. These racers have a four-rotor engine, said to be good for more than 600 horsepower in racing trim, and are predecessors to the famous 787B that scored an overall win in the 1991 24 Hours of Le Mans.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:
