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 Club and Launch Edition unveiled

If you haven't been tempted enough already to place your order for a new 2016 Mazda MX-5 Miata, the Japanese automaker is sweetening the deal even further at the New York Auto Show this week with the debut of two new editions. Most enticing is the arrival of the new Club edition (pictured above), which brings with it a number of upgrades to Mazda's latest roadster. The MX-5 Miata Club comes with 17-inch gunmetal alloys, a limited-slip differential, Bilstein shocks, tower brace and a new spoilers front and rear. That is, when equipped with the six-speed manual. (The automatic is still available as well, but does without the diff, shocks and brace.) Buyers will even be able to upgrade to BBS alloys of the same size, Brembo front brakes and the aero kit previewed by the MX-5 Global Cup racer in Chicago. The Mazda Connect infotainment system comes standard, with seven-inch touchscreen, satellite radio, nine-speaker Bose audio... the works. The Club edition isn't the only new Miata being launched in Manhattan this week, though: so is the Launch Edition. Offered to the first 1,000 customers who place their orders for a new Miata in the US, the MX-5 Launch Edition is based on the Grand Touring trim level and comes in an exclusive combination of Soul Red paint with a tan leather interior. It even comes with a few do-dads to go along with it. Mazda is taking deposits of $500 for those first 1,000 units at www.longlivetheroadster.com, and details of both these upgraded Miatas can be found in the press releases below.

Lighter, smaller, quicker and more nimble than its predecessor, MX-5 has adopted Mazda's full suite of SKYACTIV Technology and KODO-Soul of Motion design. In the process, MX-5 has shed approximately 150 pounds from its predecessor, with a curb weight of 2,332 lbs. when equipped with SKYACTIV-MT six-speed manual transmission (2,381 lbs. with the six-speed automatic transmission).

Mazda prices 2016 CX-3 from $20,840

Been eager to put your cash down on the hood of a new 2016 Mazda CX-3, but haven't known just how much to take out from the bank? You can call your branch manager now, because Mazda has released pricing details for its new subcompact crossover. The MSRP for the new CX-3 will start out at $20,840, including an $880 destination charge. (Alaskan buyers can expect to pay an extra $45 on top.) That's for the base-level Sport model with front-wheel drive. Tack on another $1,250 for all-wheel drive if you think you'll need the extra traction, but either way it'll be channeling 146 horsepower and just as much torque from a 2.0-liter inline-four through a six-speed automatic transmission. Step up to the Touring model and the retail price jumps up to $22,840 (with delivery), plus the same $1,250 for the AWD option. There's a Touring Technology package available for another $1,410 that includes moonroof, satellite radio, and cargo cover. Finally at the top of the line is the CX-3 Grand Touring for $25,870 (delivered), available with that same i-Activ all-wheel drive system, and an i-Activsense package that throws in an array of electronic conveniences and safety systems for another $1,920. So while you can get away with paying as little as $20,840 for the base model, a fully loaded CX-3 can run you as much as $29,040.
