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.

2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:

Tow truck driver hilariously bad at righting a flipped Mazda

Can rolling your car get any worse? The correct answer is yes, as this poor soul found out when he rolled his Mazda3 onto its side. Calling a tow truck might be a logical, post-rollover move, but in this case, it kind of made the situation worse.
We don't want to give away just what happened, so you'll need to scroll down and watch the video. A fair warning, though, it does contain a moment of colorful language towards the end, so watching it at work, with the volume up, might not be wise. Have a look below for the full video.
