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.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Alfa Romeo takes Spider in-house, Mazda-Fiat roadster partnership not dead

It's officially off. Following a report in March of this year that the marriage of Mazda and Alfa Romeo to produce a MX-5-based Spider was in trouble, the Italians have confirmed that it will take development in-house. "As far as the Spider goes, the final version is of course no longer the two-seater FCA co-developed with Mazda but a derivative of Project Giorgio," Maserati and Alfa Romeo brand boss Harald Wester told Car. For those not in the know, Project Giorgio is Alfa's codename for the rear-drive platform that will underpin the next-generation Spider, not to mention the replacement for the 159 sedan and a few other products. All is not lost for the Japanese-Italian partnership, though. "The Far East import will probably find a new home with Fiat-Abarth," Wester told Car. Yes, you read that correctly, Mazda is still working with FCA, and the result will eventually end up with Abarth's scorpion badge. If anything, we're more excited over this news than the idea of an Alfa MX-5. But we want to know what you think – would you rather Alfa build a new Spider on the Miata's bones, or does an MX-5 Abarth sound like more fun? Have your say in Comments.
