Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.

Mazda 787B and Vision Gran Turismo tower over Goodwood in 131-foot sculpture

Mazda is being honored at the 2015 Goodwood Festival of Speed by getting the space to create the event's annual sculpture outside Goodwood House. Given this year's theme of "Flat-out and fearless: racing on the edge," the Japanese automaker is showing off two of its racers at the very top of an intertwined spire that rises over 131 feet above the motoring event. The statue's design is the work of artist Gerry Judah, and it's made from over 132 tons of steel, including 418 beams, towering over the event. A Mazda 787B, the only Japanese car to ever score an overall victory at the 24 Hours of Le Mans, and the company's LM55 Vision Gran Turismo concept are featured at the very top. Spectators can certainly get a good view of the racers, too, because the sculpture twists to actually hang the cars above visitors. "Gerry has faithfully expressed our brand in a striking and beautiful structure that is clearly Kodo. There is a lightness and strength to the sculpture, yet it gives the cars movement and energy," said Ikuo Maeda, the General Manager of the Design Division at Mazda, in the announcement about the statue. Each year, Goodwood selects an automaker to create an artistic piece with the brand's vehicles outside of the estate's manor. Mazda shares some very prestigious company in being picked, too. Often rising high into the sky, in the past we've seen outstanding work from Audi, Alfa Romeo, Jaguar, and Porsche. Goodwood celebrates Mazda's motorsport heritage Mazda is the subject of the central feature at the 2015 Goodwood Festival of Speed Immense sculpture features Le Mans-winning Mazda 787B and LM55 virtual racer Goodwood / Leverkusen, 25 June 2015. Mazda's racing heritage is the centre of attention at this year's Goodwood Festival of Speed. The central feature of the annual motoring event is a spectacular 40-metre high sculpture in front of Goodwood House featuring two Mazda racers bursting into the sky on a twisting track of steel beams. Inspired by Mazda's KODO – Soul of Motion design, the creation of artist Gerry Judah conveys a grace and agility that disguises the complexity of the installation, which is made from 120 tonnes of steel. Each of the 418 steel beams is stacked at a different angle, curling the structure so that the cars at the top actually hang over the spectators below.
