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.

Weekly Recap: Tesla loses money, still dominates the news

Some people get an inordinate amount of attention. In politics, it's Donald Trump. In football, it's Jim Harbaugh. And in the auto world, it's Elon Musk and his always-fascinating electric car company, Tesla Motors. General Motors is spending $877 million to upgrade a factory. So what! US auto sales are up. Who cares? Tesla has a metal snake that will recharge your car! So was the week in Tesla – er, the industry. Snarkiness aside, Tesla did dominate the news cycle, led by the announcement the company lost $184 million in the second quarter. Tesla also said it expects to deliver between 50,000 and 55,000 vehicles this year, and is preparing for a full launch of the Model X crossover in September. Musk also made news during the earnings call by simply not answering a question about ride sharing, leading to speculation Tesla could be considering its own operation. While the financials were the arguably the most important company news, reports of a Model S cyber hacking were more compelling fodder for Tesla followers. Researchers were able to attack the sedan and bring it to a stop, though they required access to the car first. Tesla says it already has deployed a remedy for the situation. On a lighter note, Tesla published a video of its metal charger prototype that autonomously uncoils like a snake to power up the company's vehicles, provoking plenty of humorous comments and comparisons. Watch it and decide for yourself. While some of this might seem trivial, much of Tesla's recent attention has been warranted. It's the first startup US automaker in decades to launch from nothing and actually gain traction in the market. Sure, Musk is a lightning rod and Tesla always seems to be in the spotlight. But amid all of the publicity, it easy to lose sight of the new reality: Tesla is a force. OTHER NEWS & NOTES 2016 Chevy Volt lights up 106 MPGe The Chevy Volt's vitals are looking healthier for 2016. The second-generation plug-in hybrid racks up a gaudy 106 miles per gallon equivalent, which is an increase of eight MPGe from the 2015 model. The new Volt can travel 53 miles on electricity, a significant jump from the 2015 Volt's 38-mile range. The new car also has a 420-mile total range when factoring in the capability of the gasoline engine, which is 40 miles greater than the current car offers.

Mazda3 five-door vs. Mazda CX-3

As a talking point, it won't rival North Korea, world hunger or Mideast peace, but the ongoing tug between car and crossover continues to resonate in the hallways of Autoblog HQ. And it might also generate some discussion on Mazda showrooms, where the Mazda3 five-door and Mazda's CX-3 crossover are parked within a few feet of each other. Not only do they enjoy proximity on the showroom, but they enjoy/suffer (your choice, depending on POV) pricing proximity on the window sticker. The Mazda3 five-door is the more mature model of the two, having been introduced to a world market in fall 2003. With a commonsense footprint enclosed by almost-organic, upscale sheetmetal, the Mazda3 – especially in 5-door form – punches well above its weight in the still-nascent hatchback category. With a redesign (third-generation) introduced in 2014, along with a more recent refresh, the newest sedan and hatchback merge Mazda's KODO design philosophy with a responsive platform, available 2.5-liter drivetrain and a comfortable – if not expansive – interior. What the Mazda3 5-door (photo at left) does not give you is the crossover's high hip point, despite having ground clearance almost identical to the CX-3 subcompact crossover. And while the stated passenger volume of the Mazda3 and CX-3 is almost identical, those cubes are arranged differently; the Mazda3 offers an interior package more linear, while the CX-3 is more upright. Mazda's subcompact CX-3 (photo at top) is a more recent entry, having been developed from the Mazda2 architecture and hitting the street two years ago. It sits below Mazda's CX-9 and CX-5 in the Mazda pecking order. And it is tiny, on a wheelbase of just 101 inches and offering an overall length of just 168 inches. It is seven inches shorter than the Mazda3, with a wheelbase five inches shorter. The net effect is a more compressed environment for passengers, along with the very real challenge of fitting something inside – such as a bicycle – even when that something has its front wheel removed. In the city, I like the CX-3's compactness, and relatively unrestricted visibility when compared to the Mazda3's overall length and lower seating. But when both are equipped with their six-speed automatics, and the Mazda3 is spec'd with its available 2.5 liter DOHC four, there's almost no comparison in their performance. With that spec the hatchback has Mazda's well-hyped zoom, while the CX-3 makes do with nothing but a 4-cylinder boom.
