Mazda's EV resistance may mean CAFE trouble ahead

Is Skyactiv the limit for Mazda? The Japanese automaker has ridden its gas-powered engine technology platform to the upper end of fleetwide fuel economy among automakers in the US. But the company's lack of electrification, either hybrids of plug-in vehicles, combined with increasing sales of crossovers, may limit future fuel-efficiency gains, Automotive News reports. Mazda has no plans to add battery-electric variants across its product line, the publication says, citing comments from Mazda North America CEO Masahiro Moro. So far, the dependence on Skyactiv has worked well, as Mazda was the second automaker - after electric-vehicle maker Tesla Motors – to meet the US fuel-economy mandate of 34.1 miles per gallon for 2016. Additionally, Mazda plans to unveil the second-generation version of Skyactiv next year. Using a technology called "homogenous-charge compression ignition" (HCCI), Mazda's gas-powered engines will approximate the compression in diesel engines, boosting fuel economy accordingly. Because of that development, Mazda's Moro is "very confident" that the company will meet the US Corporate Average Fuel Economy (CAFE) mandate for 2021. With no plans for US plug-ins or hybrids (Mazda's only hybrid, a variant of the Mazda3, is sold in Japan), Moro is not so sure about meeting the 2025 CAFE mandate of 54.5 mpg (which equates to a "real world" fuel economy of about 40 mpg). Additionally, Mazda's "biggest regulatory headache" will be meeting California's mandate that 15 percent of the state's new-vehicle sales be zero-emissions within the next decade. In 2011, Mazda laid out its strategy of leaning on its Skyactiv technology instead of moving to drivetrain electrification as a way to boost fleetwide fuel economy, saying at the time that "you can't out-Toyota Toyota and you can't out-Honda Honda." The company also took a strong stance against even the idea of electrification in vehicles. According to the US Environmental Protection Agency (EPA), Mazda's model-year 2015 vehicles averaged 30.1 mpg, beating out Honda's 28.9 mpg, Subaru's 28.7 mpg, and Nissan's 28.3 mpg. Mazda's fleetwide fuel efficiency increased from 29.4 mpg for the 2014 model year, and from 28.1 for the 2013 model year, according to the EPA.

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.

Junkyard Gem: 1982 Mazda RX-7 GSL

The early Mazda RX-7 was one of the few bright spots for sports-car shoppers during the Malaise Era, a lightweight and simple rear-wheel-drive machine with a screaming Wankel engine under the hood. Even though it was designed mostly as a means of getting Japanese car buyers a loophole to keep their engine-displacement-based road taxes low, the early RX-7 sold well in North America. I still find these cars during my junkyard travels, but the 1981-1983 FB-series RX-7s have been getting scarce in recent years. Here's a very solid '82 that showed up in Denver during the winter. Japanese cars of this era tended to rust early and often, but this one appears to be absolutely corrosion-free. The odometer shows just a hair over 100,000 miles, so I'm guessing this car spent decades in covered storage. The seat leather shows a few rips, but the interior looks pretty good overall. The body has some dents and dings, nothing serious. It wouldn't have taken much to get this car back on the road and looking good. The GSL package got you four-wheel disc brakes, a limited-slip differential, and these cool-looking pillar badges.  The list price on a new 1982 Mazda RX-7 GSL came to $11,895, or about $32,350 in 2020 bucks. A new Datsun 280ZX coupe went for $14,499 that year, but was a much more powerful and prestigious car; the less opulent 200SX was just $7,739. If you wanted a new Celica Supra, the price tag was $14,598. The final year for the Fiat-badged 124 Spider (they were sold with Pininfarina badging for a few additional years) was 1982, and that car cost $12,290. Meanwhile, your Chevrolet dealer had new Z28 Camaros starting at $9,700 that year; the RX-7 would eat up the Camaro on a tight road course but would be blown away on the straights. The 12A rotary engine in this car made 100 horsepower from just 1.1 liters of displacement, putting smiles on the faces of those Japanese road-tax payers. Unfortunately, fuel consumption was scary, particularly in the immediate aftermath of the 1979 Oil Crisis. Why did this car end up in a place like this? It was found in an office parking lot with a flat tire and expired registration tags and towed away. Then it failed to attract any bidder interest at the subsequent auction and U-Pull-&-Pay picked it up for next to nothing. So, if you ever wanted an early RX-7, buy the next cheap one you find before it meets a fate similar to that of today's Junkyard Gem. This content is hosted by a third party.
