World Car of the Year finalists announced

To say the 2014 Geneva Motor Show was packed full of news is an understatement as big as the show's home at the Palexpo convention center. Despite everything that we were able to cover during this year's show, there's still more coming out of Switzerland, including the announcement of the finalists for the 2014 World Car of the Year Awards.
We reported on the original list of finalists over three weeks ago, and now, that initial list has been pared down to three finalists for each of the five awards. The finalists were announced at a press conference by frequent Autoblog contributor and co-chair of the awards, Matt Davis (above).
The finalists for the overall title of 2014 World Car of the Year are the Audi A3, the BMW 4 Series and the Mazda3. The World Luxury Car of the Year will be either the Bentley Flying Spur, the Mercedes-Benz S-Class or the Land Rover Range Rover Sport, while the Performance Car of the Year will be awarded to the Chevrolet Corvette Stingray, the Ferrari 458 Speciale or the Porsche 911 GT3 (which, um, yeah...).

Jay Leno celebrates Mazda Miata's 25th birthday

Ask a car enthusiast what the best driver's car on the road is, and the Mazda MX-5 Miata is very likely to come up rather quickly. Unjustly saddled with a reputation as a "chick's car," the Miata has been, over its three generations, one of the finest driving instruments ever built - it's light, agile and rear-wheel drive with direct, snappy steering, an engine that revels in being revved and a precise, smooth-shifting transmission. The fact that it's ridiculously affordable and reliable is simply a bonus.
It should come as no surprise then, that a car with these traits has endured for 25 years, a milestone reached only by some of the most famous nameplates in the auto industry - Corvette, Mustang, F-150, SL, M3 and so on. To celebrate its 25th anniversary, Jay Leno spent some time with the little roadster that could, while also chatting with two of the Mazda employees that were central to the MX-5's arrival on the world's automotive scene, Bob Hall and Tom Matano.
Take a look below for the latest video from Jay Leno's Garage on the excellent Mazda MX-5 Miata.

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.
