2014 Mazda3 breaks cover early, in Euro-spec at least

We're set to get a closer look at the US-spec 2014 Mazda3 later today, but AutoExpress has the first peek at the machine's European cousin (after initial leaks reportedly came from a Czech outlet). The photos show a compact that's taken plenty of design inspiration from its older sister, the Mazda6. That's excellent news, as the larger car's dynamic front fascia, accentuated fender arches and long nose translate well to the Mazda3. Inside, there are are new and improved material choices, and the longer wheelbase means occupants get to enjoy more room than before. There's also a larger trunk with 12.3 cubic feet of cargo capacity.
Buyers in the EU can get their hands on a 1.5-liter Skyactiv-G gasoline engine with 99 horsepower, though the old 2.0-liter four-cylinder will still be available in either 118 hp or 163 hp configuration. A 2.2-liter diesel tops out the engine choices.
The 2014 Mazda3 is lighter than its predecessor and boasts disk brakes and a multi-link rear suspension on every trim. That means this thing should be fun to shuffle around. Stay tuned for details on the US-spec variant later today, including a lot more images of the good-looking hatch.

Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.

Mazda recalls 1.37 million older vehicles for ignition switch short [UPDATE]

UPDATE: Mazda has confirmed to Autoblog that NHTSA's figures and list of effected models are accurate. Mazda is recalling 1,368,500 older vehicles in the US that date as far back as the late '80s because a potential short circuit in the ignition switch could cause a fire. According to the National Highway Traffic Safety Administration, the models include: 1990-1995 323 1993-1998 626 1993-1995 929 1989-1998 MPV 1993-1997 MX-6 1992-1993 MX-3 1990-1998 Protege Mazda reports that over time the grease around the switch's contact points can carbonize and become conductive, which can eventually lead to a short circuit. In some cases this results in smoke, but it could also lead to a fire. According to company spokesperson Tamara Mlynarczyk to Autoblog, there're no accidents, injuries, or fires in the US. Once the vehicle is running, the potential fault also doesn't affect drivability. Documents from NHTSA (as a PDF), indicate there was a fire in one of these vehicles in Japan in 2002 that could have been linked to this issue. The recall should begin in December. In its announcement of the issue below, Mazda reports 1.2 million vehicles affected and includes the 1990-1996 323/Protege. Autoblog has reached out to the company to understand the discrepancy.

In the affected vehicles, grease applied to the contact points inside the ignition switch may become conductive and overheat. CONSEQUENCE: If the ignition switch overheats there would be an increased risk of a fire. REMEDY: Mazda will notify owners, and dealers will replace the ignition switch, free of charge. The recall is expected to begin December 15, 2015. Owners may contact Mazda Customer Experience Center at 1-800-222-5500, option#6. Mazda's number for this recall is 8715J.
