About this time last year, Cadillac's CTS added CNET's Tech Car of the Year to its increasingly crowded trophy case. Its entertainment system's recording capability was one of the things that impressed us, and, presumably, the voters. This year, CNET asks its readers to choose between three imports and two domestics, none of which are Cadillacs.
BMW's M3 Convertible DCT gets a spot on the ballot with its dual-clutch transmission. We wonder if the car's recent recall for transmission problems will affect its standing. The Nissan GT-R shows up again, as you might expect with its cabin full of g-whiz electronics, from the in-dash performance computer to the quick-loading navigation. Lincoln makes the list for its THX-equipped MKS and Infiniti's EX35 Journey gets recognized for its lane-departure warning system and park-assist cameras.

Chrysler has managed to stay out of the doom and gloom news for a few weeks now, which goes to show that going private can have its benefits. But things couldn't stay quiet forever, and as if the company needed something else to deal with, it's now in row with German transmission supplier Getrag over a potentially failed joint venture. Chrysler uses Getrag double-clutch transmissions (DCT) in the Euro-version Dodge Journey (seen above), and is planning on adding the Euro Avenger and Sebring to the DCT lineup. Getrag signed an agreement with Chrysler to build a factory in the U.S. that would also supply Chrylser's American products with DCTs, and in return for Chrylser agreeing to get such transmissions only from Getrag, Getrag would get $300 million to finance and tool the factory. According to Getrag, it only intended to borrow the funds if said funds were guaranteed by the German government. According to the German government, it would only guarantee the $300 million loan if Chrysler put that same amount in an escrow account to guarantee repayment. According to Chrysler, it had no idea of such an arrangement, and Getrag never should have signed the agreement if it meant Chrysler needed to back Getrag's loan with its own cash. And that's how court cases are made. While the factory remains in limbo, Chrysler needs to find another supplier for DCTs for its American cars, and do it in a hurry.
The 2008 BMW M3 won't be the only 3-series to get Bavaria's newest dual-clutch gearbox. According to documents leaked out of BMW's Australian arm, the 2009 335i coupe will be available with a revised version of the DCT gearbox, at least Down Under... for now. The dual-clutch transmission is the same unit fitted on the V8-powered M3, but some changes to the software are planned to better suit the turbocharged, 3.0-liter inline-six powerplant. There's no word on when the DCT gearbox will be available on U.S. shores and we don't know what kind of premium the seven-speed tranny will carry, but a DCT-equipped M3 commands an additional $2,700 over the six-speed manual, so expect a similar price when the revised 335i goes on sale, likely later this year.
Dual-clutch transmissions are washing over the automotive industry like a wave, and Renault could be the next to hang ten. The French automaker intends to use more efficient transmissions – specifically DCTs and CVTs – to help meet its emissions-reducing targets.
Although Renault could easily borrow the continuously-variable transmission from its corporate cousin Nissan, the speculation is that it could also develop its own dual-clutch gearbox. Although Nissan uses one in the new GT-R, it's outsourced from Borg-Warner. If Renault did develop its own DCT, it would likely employ lighter-weight dry clutches, and would join the growing list of carmakers with DCTs that will soon include Fiat, Volvo, BMW and, of course, Volkswagen.
Dual-clutch transmissions are emerging as the latest trend in automotive gearboxes, and the Italians aren't about to miss out on the newest fashion. Fiat announced earlier today a new family of six-speed transmissions, called C635, that will premiere as a manual in June 2009, followed by a dual-clutch version in September 2009 before the automated manual comes out in 2010.
The C635s will be offered on a range of Fiat products including Lancias and Alfa Romeos, and will be capable of handling 35kgm of torque. They'll be built by Fiat Powertrain Technologies at its Verrone plant 75km outside of Turin, handled by a workforce that will more than double to 1100 staff. Called the Dual Dry Clutch (DDC) transmission, Fiat's will follow Volkswagen's seven-speed second-generation DSG (which also switches from wet clutches to lighter-weight dry ones when it debuts on the Golf this month), Volvo's Powershift transmission (due next month) and the BMW M3's new M-DCT (available from March)
