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.

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

2016 Mazda MX-5 Miata gets 25 percent fuel economy boost

Just days after revealing full pricing and specs for each trim level of the 2016 MX-5 Miata, Mazda is spilling the beans on the roadster's fuel economy. As it turns out, the numbers show an impressive boost over the previous generation. All 2016 Miatas in the US are equipped with a 2.0-liter four-cylinder that makes 155 horsepower and 148 pound-feet of torque. With a six-speed manual, the EPA estimates fuel economy of 27 miles per gallon city, 34 mpg highway and 30 mpg combined. Buyers choosing the six-speed automatic, which is a $1,075 option (that you should absolutely not choose), are expected to get 27 mpg city, 36 mpg highway and 30 mpg combined. Compared to the previous-gen model with a six-speed manual, these latest numbers represent a 25-percent improvement in mileage. The boost in economy for the Miata likely comes from a variety of sources. Underneath the hood is one of Mazda's latest Skyactiv engines, and the loss of around 150 pounds from the last gen helps too. Production of the latest version of the famous roadster is already underway, and they should start arriving at dealers in the late summer. 2016 MAZDA MX-5 MIATA FUEL ECONOMY IMPROVES DRAMATIC 25 PERCENT VERSUS OUTGOING MODEL 24/04/15 - Mazda's Flagship Roadster Highlights Improvements Displayed by SKYACTIV Technology - IRVINE, Calif., April 24, 2015 -- Lighter, quicker and more nimble than its predecessor, the 2016 Mazda MX-5 Miata demonstrates the power innovation can have when re-engineering a roadster from the ground up. In addition to all of the aforementioned improvements the 2016 MX-5 has, fuel economy can now be added to the list, with MX-5 achieving an EPA-estimated 27 mpg city/34 mpg highway/30 mpg combined when equipped with the standard SKYACTIV-MT six-speed manual transmission (EPA-estimated 27 mpg city/36 mpg highway/30 mpg combined when equipped with the six-speed automatic). This performance represents a 25-percent increase in fuel economy versus the 2015 MX-5's EPA-estimated fuel economy when paired with the outgoing model's available six-speed manual transmission, highlighting the benefits of SKYACTIV Technology. "SKYACTIV Technology is more than a catchphrase for Mazda; it's a total effort to increase efficiency, improve performance, safety and technology and instill each Mazda vehicle with a directness and responsiveness that's unmatched in the segments in which our vehicles compete," said Jim O'Sullivan, president and CEO, Mazda North American Operations.
