Mazda keeping non-hybrid, non-electric Skyactiv strategy

Mazda still thinks that it can buck the trend of adding those fancy batteries and electric motors to its cars. At least for a little while longer. Hopefully. Speaking to Auto Express recently, Mazda's European boss, Jeff Guyton, said that he expects his company's cars to be able to get a lot more efficient without resorting to any of that fancy electrification stuff. "I think there's at least 20-30 percent better fuel economy by the end of the decade," he said. He said that he expected to get to Europe's low target of 95 grams of CO2 per kilometer, "without any significant deployment of electrical drive." This part is all in line with Mazda's long-term Skyactiv strategy, as laid out back in 2011 and first mentioned publicly in 2010. Remember, this is the company that once proudly proclaimed, "Not Electric. Not Hybrid. Not A Drag To Drive." As explained back in 2011, Mazda hopes to wait until other automakers have done all of the heavy lifting on developing plug-in and hybrid tech so that when Mazda enters the market, things will be cheaper. Of course, Mazda has been quietly testing all-electric vehicles and Guyton said that there may be an Mazda EV at some point. "We are interested in electric technology and it will be in the distant future when it will be quite important," he told AE. "But we think it will take some time to be commercially attractive without tax payer-funded incentives." How much of a delay? Well, there is a gas-electric Mazda 3 hybrid available in Japan that uses some powertrain parts from the Toyota Prius, and we all know that the Prius has been around for ages. Maybe in 2025, Mazda will come out with a Leaf-based Mazda 2. Related Video: Green Mazda Fuel Efficiency Electric Hybrid skyactiv mazda skyactiv

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.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands
