Crash test videos show how rust compromises safety

These recently released Swedish videos serve as a reminder that rust isn't just a cosmetic flaw, when it comes to cars. The insurance company Folksam and the homeowner organization Villaagarnas Riksforbund gathered examples of two relatively popular, but by now rusty cars, and then performed crash tests with them at the Thatcham Research facility in Britain. The results are sobering. The rustier cars chosen for the tests were first-generation Mazda6s, cars that have a reputation for early-onset rust in salty surroundings, such as the Nordic countries in Europe or the Salt Belt in the U.S. The cars in the other end of the spectrum were fifth-generation Volkswagen Golfs, which thanks to their body treatment only really start to show rust at over ten years old. But rust isn't just on the surface, it goes bone deep. While the Mazda did decently well in Euro NCAP testing as a new car, there's now a 20 percent higher risk of death in the 2003-2008 Mazda due to the degradation of its bodyshell. In the rusty car, the chassis rail separates from the floor, the footwell ruptures, the sill gives way, the seat mountings move and the dummy's head hits the B-pillar; all important failures, despite Thatcham saying the cars actually performed better in the crashes than they expected with all the rust. But still, the corroded structure isn't able to transmit loads in the way it was originally designed to do. This content is hosted by a third party.

The Golf does significantly better — despite rust flakes flying when the Golf hits the wall — as the years have only caused it to lose a single point. An important thing to remember is that the cars aren't tested in comparison to corresponding new, 2018 cars: the tests are in reference to the crashworthiness standards in place when they were new. The cars' airbags inflate like they were supposed to, but on the Mazda the dummy's head bottoms out the airbag due to the car's structure failing, meaning the airbag cannot perform as designed. Driven cautiously, an older car is still mostly fine for driving around. But tests like these remind us that it's not enough that a car runs and drives, if the body has turned into Swedish knackebrod. And if you repair the visible rust and the structure underneath remains as compromised as ever, there's an ugly truth under all the bondo. Perhaps it isn't such a bad idea to have yearly roadworthiness inspections.

Goodwood Festival of Speed celebrating Mazda this year [w/video]

Mazda gets to wear the crown and sash as the doubly honored marque for the Goodwood Festival of Speed this year. The Japanese brand will be the focus of the Central Feature, the sculpture that sits outside Goodwood House, and its race cars will be the focus on the lawn, where there will be at least one representative from "every era of Mazda's motor sport achievement." The theme for this year's event is "Flat-out and fearless: racing on the edge." The showcase, of course, will be the 700-horsepower, rotary-engined 787B that won the 24 Hours of Le Mans in 1991. It will run up the 1.6-mile Hillclimb while a Mazda challenger from the World Rally Championship runs the Forest Rally Stage, joining Andros Trophy ice racing and sportscar racing Mazdas. The festival happens from June 25-28 this year, and there's a press release with more details down below the video recap from 2014 and Mazda 787B Le Mans lap. This content is hosted by a third party.

Le Mans-winning 787B to headline fantastic Mazda line-up at FoS 2015 Feb 18, 2015 -- Mazda is the only Japanese manufacturer to have won the world's most prestigious motor race – the Le Mans 24 Hours – and the victorious rotary-engined 787B, with its distinctive sound, is certain to be a crowd favourite as it winds its way up Goodwood's iconic 1.16-mile Hillclimb at the Festival of Speed this year. The 787B is part of a fabulous collection of racing and road machines that will be brought to the Festival by Mazda, in the year in which the company is also being honoured by the iconic Central Feature outside Goodwood House. Further motor sport success has been achieved in touring cars, the World Rally Championship, Andros Trophy ice racing and sportscar competition in the USA – in which Mazda's pioneering SKYACTIV-D turbodiesel technology is breaking new ground currently. In fact, every era of Mazda's motor sport achievement will be marked by some incredible competition cars both on the Hillclimb and the Forest Rally Stage as we celebrate the FoS theme 'Flat-out and fearless; racing on the edge'. The Moving Motor Show on June 25, will also showcase many of the key models from Mazda's current range.

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:
