Mazda has announced that the company will employ its new SkyActiv technologies in the 2012 Mazda3. The vehicle is set to debut at Toronto’s upcoming Canadian International Auto Show, and it will boast the Japanese automaker’s much gabbed-about SkyActiv-G gasoline four-cylinder engine and SkyActive-Drive gearbox.

Mazda says that the two new pieces of hardware should help the Mazda3 deliver more torque at mid-range engine speeds, and that the trick should be good enough to increase fuel economy along the way. As you may recall, the SkyActiv-G engine is a direct-injection design with a low-friction block to minimize mechanical drag.

This will mark the first time that either the new engine or the gearbox has ever been offered in a production vehicle, and the company’s designers have thrown in a few exterior tweaks to mark the occasion. Buyers can look forward to slightly revised bumpers front and rear as well as new 16- and 17-inch wheels. The more efficient Mazda3 is expected to land in dealerships by the end of this year. Hit the jump for the full press release.

Report: Xtrac develops cheaper gearbox that behaves like dual-clutch

Filed under: Technology

Xtrac IGS

Dual-clutch transmissions are the current Holy Grail when it comes to transferring underhood power to the wheels of the car. Nearly every automaker that does serious business around the world offers DCTs, and the ones that don’t very likely soon will.

It’s easy to understand the draw of the DCT: better performance and greater efficiency. But there are also problems. For instance, two clutch mechanisms mean (theoretically, of course) twice the potential repair costs, and DCTs are generally more expensive than either standard manual transmissions or conventional automatics with torque converters.

Xtrac, a company firmly entrenched in transmissions for racing applications, has developed a new technology called the Instantaneous Gearchange System, which uses a ratcheting mechanism to couple the gear hubs with the main shaft. The system has been under development for two years and has reportedly been put into race duty by multiple motorsports teams.

Apparently, the IGS technology will be less costly than other dual-clutch transmissions and could potentially be adopted by various global automakers. Hat tip to David!

Report: Recall, stop-sale issued on 2010-11 Subaru Outback and Legacy models over gearbox flaw

Once again, Subaru’s mainstay models, the Outback and Legacy, appear to be girding for a recall. Both models have already faced callbacks for leaky CVT hoses and wiring issues, but according to Inside Line, a new issue affecting a number of manual transmission-equipped 2010 and 2011 models will not only precipitate another recall, but also a stop-sale on all potentially-affected vehicles.

According to the National Highway Traffic Safety Administration, the oil lubrication hole in the six-speed manual transmission has not been drilled on the affected vehicles, which can cause gears to break. NHTSA issued a statement, saying:

“If the transmission gears are not properly lubricated, a groaning sound may begin to develop, alerting the driver to a problem. If this sound is ignored and no action is taken, the gears will eventually break and this condition will lead to vehicle power loss, possibly resulting in a crash.”

Vehicles will be repaired, free of charge, at any Subaru dealer in America. Most will simply have an oil lubrication hole drilled, though the automaker has informed its dealer network that vehicles with 6,250 miles or more will require the replacement of the third through sixth gearsets, as well as the main shaft.

A total of 809 Outback and Legacy models are affected by this recall, which is expected to officially go into effect on August 6. In the meantime, owners are urged to contact their local dealers as soon as possible to have this problem corrected.
