2014 Mazda3 configurator zoom-zooms to life

The 2014 Mazda3 is probably going to be on a lot of shopping lists, thanks to its striking good looks, clean interior treatment, fuel economy and driving character. If it happens to be on your personal list of new cars to test, you'll be happy to see that the configurator for Mazda's newest product has officially gone online.
In terms of build-your-own web items, configuring a 3 isn't much of a departure from the rest of the Mazda range. Most of the work comes from choosing one of the three trim levels - Sport, Touring and Grand Touring - and selecting either the 155-horsepower, 2.0-liter, Skyactiv four-cylinder or its larger sibling, the 184-horsepower, 2.5-liter, Skyactiv four. From there, a simple range of color and interior finishes are available, before a slim list of packages, options and accessories. Really, Mazda's made it easy to get through this build process.
Click on over to the configurator and take a look at the options, colors and prices for Mazda's newest five-door hatchback.

Mazda Hazumi Concept previews next Mazda2 in Geneva [w/videos]

The official photos of Mazda's Hazumi concept leaked out yesterday, but we have finally gotten to see it in real life at the Geneva Motor Show. Our view is that its Kodo lines looks as good on the diminutive car's sheet metal as they did in photos.
The Hazumi was designed to appear to be bursting with energy, and it seems to deliver. While Mazda refuses to actually say that this is the concept for the next Mazda2, it makes it clear that the little hatchback is "foreshadowing Mazda's next-generation subcompact car." We can all read between the lines.
Hazumi also introduces the new Skyactiv-D 1.5-liter diesel engine but details about it are scant at the moment. The specs for the engine are still unannounced, but the company promises that it is both very efficient and has lots of torque for its size. Mazda is also promising that its Mazda Connect infotainment system will be available in the car too. Scroll down for the brief press release a brace of videos that celebrate the tiny concept's arrival.

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.
