2016 Mazda CX-9 images leak online

We will get a complete look at the next-gen Mazda CX-9 during the big debut at the Los Angeles Auto Show within the next couple of days. Until then, these newly leaked images from Carscoops provide a great preview of the upcoming three-row model ahead of the event. These shots echo the design from the recent teaser sketch quite closely, but the headlights aren't as sharply defined on the real thing. The single photo of the front end largely hides the grille, but it appears to follow the shield-like styling of the latest CX-3 and CX-5. The two images of the rear show narrow taillights like the brand's other CUVs, but with a thin strip of chrome that runs over the hatch to visually connect both sides. Bulging fenders at both axles lend some extra toughness to the shape. The CX-9 looks to continue Mazda's recent knack for great interior design. The stylists finish the dashboard in a mix of copper and black, and metallic trim helps lighten things. The infotainment system rises from the center, and comfortable looking leather seats pick up the brown in the color scheme to lend a luxurious atmosphere. The leaked photos didn't come with any technical info about the CX-9. However, rumors suggests a powertrain with a 2.5-liter turbocharged four-cylinder and all-wheel drive. More details should arrive during the crossover's imminent launch in LA.

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.

2016 Mazda MX-5 Miata design walkaround

By now, you've likely read what we think of the 2016 Mazda MX-5 Miata's new looks both inside and out, and you've probably poured over the available photos and started to make up your own mind about the roadster's radically more aggressive new appearance. More than likely, however, you haven't heard much from Mazda itself about its new design, and we're here to remedy that. Join Autoblog as we go over the new Miata from tip to tail with Derek Jenkins, Mazda North America's director of design. Jenkins, a veteran of both Audi and Volkswagen design studios, has been with the Japanese automaker for nearly four years, and he's kept a close eye in the ND Miata program along with his team in Irvine, CA. Check out our video to see Jenkins explain his team's exterior and cabin handiwork and to learn a little more about why the new model graduates from the Miata's historically cute and friendly aesthetic to something altogether more assertive.
