Volvo to get dual clutch gear box and 10% economy boost
The box that Volvo will use is built by Getrag while Borg-Warner supplies the Volkswagen units. Initially availability will be limited to diesel engined variants, but it will expand to gas engined units and other vehicles built from the same platform such as the European Focus, the new Freelander and the Mazda 3. Eventually the gearbox may also appear in US Ford models. The dual clutch box offers a ten percent boost in fuel economy compared to a conventional automatic transmission. Given the timing this probably means that some patents on the original dual clutch design are probably expiring which is allowing Getrag to hop on this bandwagon. Hopefully it's just a matter of time before these transmissions become more widespread.
