Volvo shows off new gearbox by pulling 750 tonnes from standstill

Dual-clutch gearboxes are fitted to everything from family wagons to world-crushing Bugattis in cars, but haven't had quite the same impact in the trucking world. Having launched its I-Shift dual-clutch gearbox in 2014, Volvo has now added crawler gears to the system in an attempt to broaden its appeal. Unsatisfied with a traditional launch, the company has shown off the transmission by pulling a 750-tonne load from standstill.Read More

Volkswagen reportedly working on new 10-speed gearbox

How many gears are too many for the average commuter vehicle? If you’re pulling a load of cattle across Saskatchewan, then a semi-tractor unit with nine gears should suffice. But if you’re Volkswagen, then the magic number for your upcoming models is in fact 10. Read More

Volkswagen's new 207 bhp Golf GTi Cabriolet

The new Golf GTI Cabriolet will be shown next week at the Geneva Motor Show. It uses the same 154 kW 2.0-litre turbocharged four as the GTI hatchback, mated to a six-speed manual or six-speed dual-clutch DSG gearbox, enabling a 0-100 km/h (62 mph) time of 7.3 seconds (versus 6.9 seconds for the hatch), and a top speed of 237 km/h (147 mph).Read More

Honda announces Dual Clutch Transmission for large-displacement sport motorcycles

Dual Clutch Transmissions (DCT) are still a relatively rare breed, though in the past few years we have been inundated with them in high end automobiles. By using a separate clutch for odd and even gears, gears can be changed without interrupting power by applying the engine's torque to the next gear just as it is being disconnected from the previous one. This enables quicker and smoother gear changes and delivers better fuel economy while reducing emissions. Honda’s newly-announced, fully-automatic motorcycle DCT is a first for large-displacement sport bikes and will debut on the new VFR set for release in 2010. Read More

Mercedes AMG builds a new Gullwing

For the first time in its 40 year history, the Mercedes-Benz performance brand AMG has developed a vehicle completely in-house: the Mercedes-Benz SLS AMG. This "super sports car" takes an AMG 6.3-litre V8 front-mid engine developing 420 kW/571 hp peak output, seven-speed dual-clutch transmission and sports suspension with aluminum double wishbones, wraps it in an aluminum spaceframe and throws in a set of always-in-style gullwing doors. The combination of the company's first ever use of an aluminum chassis and body frame coupled with lightweight, high-strength components such as a carbon-fiber driveshaft delivers a kerb weight of just 1620 kilograms and a power-to-weight ratio of 2.84 kg/hp. Provisional performance figures put acceleration at 0 to 100 km/h in 3.8 seconds with a top speed of 315 kmh.Read More
