Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda recalling 88k vehicles for ECU glitch

Need a break from news about the General Motors ignition switch recall? This Mazda recall should serve as a nice change of pace. It involves 88,000 cars across the globe, and focuses on the brand's three most recent (and important) models - the Mazda3, Mazda6 and CX-5.
The issue rests with Mazda's new i-ELOOP regenerative braking system. Apparently there's a problem with the ECU program that monitors whether a capacitor in the regen system is working. Acceleration is affected, and in severe cases, the engine could stall. There have been no mention of accidents or injuries due to the issue, and the glitch itself can be cured by an ECU reflash.
As i-ELOOP is a fairly new system for Mazda, particularly in the US, the total number of affected models is rather low, with just 6,500 US cars affected. Europe is hit hardest, with 38,000 models while Mazda's home market of Japan adds 27,600 cars and crossovers. Affected models were built between October 2012 and January 2014.

Junkyard Gem: 1989 Mazda MX-6 GT Turbo

The Mazda MX-6 is best-known in the United States as the sibling (or maybe first cousin) of the Ford Probe, which almost became the successor to the Fox Mustang. The MX-6 and Probe were well-engineered and very quick for the era, but never enjoyed great American-market sales success. Here's a rare first-generation MX-6 GT that I photographed last week in a Denver self-service yard. 145 turbocharged horsepower was pretty good for 1989, when a new Honda Prelude Si had 135 horses and the far more expensive BMW 325i ($24,650 for the 325i coupe versus $14,499 for the MX-6 GT Turbo) had 168. This one doesn't have the optional four-wheel steering, but it does have the three-way adjustable suspension. If you drove a turbocharged car in 1989, you needed a nine-band equalizer with analog sliders on the radio. It was the law. It's not rusty, but at 205,575 miles it's worn out.
