Volkswagen has unveiled its next-generation seven-speed DSG transmission - and as you’d expect, it’s lighter, smaller and more efficient.

The new paddle-shift gearbox, codenamed DQ200, uses a pair of dry organic-bonded friction linings that don't require cooling in preference to the six-speed version’s twin wet clutches. The system also requires less power for the gear selection and clutch servo system, boosting fuel efficiency and powertrain performance. Mounted transversely for superior packaging, the gearbox measures just 369mm long and including its dual-mass flywheel weighs in at 79kg – 7kg less than the six-speed transmission.

Having a seventh cog has allowed VW’s engineers to shorten the first three gears for snappier acceleration from standstill, while a longer top gear boosts motorway refinement and economy. The DQ200, which can take outputs up to 170bhp and 184lb ft of torque will be used throughout the VW model line-up, from Polo to Passat. The first recipient will be the 1.4-litre TSI twincharge and 1.9 TDI Golf GTs, and it’s not expected to cost more than the current £1330 VW charges for its six-speed DSG transmission.
