Weight savings

  • 6.0 kg – electrical and electronic system.
  • 40.0 kg – engines (using smaller displacement units combined with turbo charging).
  • 26.0 kg – running gear (suspension, EPAS).

The body assembly (shell plus systems) saved up to 37.0 kg, of which:

  • 0.4 kg – revised dashboard skin molding process resulting in thinner parts.
  • 1.4 kg – optimised steel cross car member (behind the dashboard)
  • 2.7 kg  – AC module size optimised (the same optimisation process was used on Toyota / Scion iQ)
  • 7.0 kg – laser welded high strength steel alloy seat frame assemblies.
  • 23.0 kg – body shell, by use of more high strength steel alloys
  • 2.5 kg – collective small weight savings by component elimination

Whilst impressive, this weight reduction programme is relatively conservative – emphasising the further weight saving built into the vehicle which will be used later in the model life cycle.

Volkswagen MQB platform material strategy

The initial engine range consists of a turbocharged 1.4l petrol engines with several outputs, and two turbo diesel engines. Both engine groups are new, with the same orientation of the cylinder head so that the exhaust leaves the engine bay from the back ‘face’ of all engines.  The new ‘EA211’ 1.4l petrol engine is turbo charged with direct fuel injection to deliver between 85 PS and 140 PS, Indeed the 140 PS unit has cylinder de-activation so it can run of two cylinders at part load, delivers 18 PS more than the Golf VI unit and uses 4.8l per 100 km instead of 6.2l per 100 km (58 mpg instead of 45mpg – Imperial).  The new ‘EA288’ VNT turbodiesel engines will displace 1.6l (105 PS) and 2.0l (150 PS). Of all the engines and gearboxes which will be unveiled for Golf VII, only the 6 and 7 speed DSG transmissions are carried over from the Golf VI.

Active safety

The electronic traction control which uses the ESC system and front brake callipers to stop wheel slippage on acceleration is now standard on all versions of Golf VII – it was only standard on the GTi version of Golf VI. Also standard equipment includes driver selectable engine response calibration combined with optimisation od AC usage (4 modes for manual transmission cars, 5 modes for those with DSG).

The suite of active safety systems – which are not standard on all models – includes:

  • 77 GHz long range forward radar (mounted in the lower front grille) with autonomous braking and adaptive cruise control.
  • Short range LIDAR  (mounted between the rear view mirror and windscreen) to provide complete autonomous braking at speeds up to 18.6 mph (30 km/h).
  • Lane keeping assist with the ability for the driver to select if the system should self-correct at the slightest error or a slightly less aggressive level.
  • Blind spot detection via rear mounted 24.7 GHz radar modules.
