Feds investigating 2010-11 Mazda CX-9 CUVs over braking issues

The National Highway Traffic Safety Administration is investigating 62,000, 2010-2011 Mazda CX-9 models over brake problems. The government safety watchdog says it has received seven complaints of an observed loss of power braking power to stop the crossover, according to the The Detroit News.
The NHTSA complaints say that the problem causes a hard pedal, increased braking effort and reduced braking effectiveness. Some complaints allege that they hear a hissing noise during braking similar to the sound of air leaving the tires. No injuries or crashes have been reported.
"As always, we are fully cooperating with NHTSA on their investigation. We cannot comment further at this time," said Mazda spokesperson Tamara Mlynarczyk to The Detroit News.

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.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
