    *UPDATE* GM Files Patent for 7-Speed Dual Clutch Gearbox

    September 26th, 2013

    Patent Drawings published on September 19th reveal that General Motors has filed a patent for a 7-Speed Dual Clutch Transmission. While there has been talk about a conventional GM 8-Speed automatic for a while, a 7-Speed DCT could give GM an upmarket transmission to offer in premium products from Cadillac or the Chevrolet Corvette.

    At the moment, the 2014 Corvette Stingray will be shipping with a 6-speed auto when the buyer opts not to row his own, leading us to believe that this 7-Speed DCT could be offered in the Corvette in the future. We also speculate that with a couple of V-series Cadillacs on the way, the timing could be right for an introduction in one of them.

    Update: A reader points out that the output shaft in the above drawing is offset to the side of the transmission (label 16). This means it is highly unlikely that this is a rear wheel drive transmission, but instead is a front wheel drive, transversely mounted transmission.

    The 9-speeds that Jeep is using are a ZF design but built by Chrysler.

    My complaint with DCTs is their performance in traffic situations. I hope GM can address that with this transmission.

    The Ford one (Powershift or whatever it's called) used in Volvos is quite smooth even in traffic. Sampled it once in Sweden with a 1.6L diesel V60 wagon and with that engine I actually liked it better than the standard manual gearbox.

      I guess Canada will homologate these Chinese EVs with no hesitation then.  I am not surprised by this, its just that buying a NEW car built for North America for North Americans  from an american dealership in the usa and trying to bring it over the Canadian border to drive in Canada would land you in a confiscated car unless the car would be "Canadianized".  I guess it wasnt homologized at the american dealership but these Chinese EVs will be would be the difference.  What Im trying to say now is that, having a speedometer in MPH is a danger on Canadian roads  regardless if KM/H is also on the speedometer albeit in smaller print rather than actually having the Chinese EVs really pass Canadian safety regulations...   I understand that Chinese EVs have been approved for European roads. North American safety regs are similar... But why am I whining?  I am sounding like a dumb ass republican or a conservative from Alberta  or in this case the CAW!!!!

      Safety experts and tech critics have long condemned the Ring devices for security risks and privacy violations, not to mention their role in building the largest civilian surveillance network in US history. Last summer, the Electronic Frontier Foundation warned that Ring was actively eroding civil liberties in the US for profit. Amazon subsidiary Ring, the company behind those AI doorbell cameras that have exploded in popularity over the last few years. Back in October, Ring announced that its devices would soon be looped into a network of Flock AI surveillance cameras. That network, an investigation by 404 Media found, has been available to local and federal police and enforcement agencies like ICE — leaving many worried that their Ring doorbell cams are now feeding into a government panopticon. Fury as Amazon Ring Cameras Are Hooked Up to ICE System If you have RING, time to rethink who you use for video surveillance.
