The panel van, people carrier and Kombi have all undergone the changes, which boost fuel economy and slash emissions.
The cleanest variant – the low roof Transporter 114 Bluemotion – returns 44.8mpg and 166g/km. VW claimed this version is capable of 780 miles on one tank of diesel.
There are also two other Bluemotion Technology models with 84- and 114hp respectively, both of which offer identical economy and emissions figures of 40.4mpg and 184g/km. Each is said to be capable of a further 50 miles per tank.
Low rolling resistance tyres, battery regeneration systems and cruise control (to better maintain average speeds) are the elements behind the increased eco performance, while the Bluemotion model also has a tyre pressure warning light to remind drivers to keep the psi at the correct level for economy purposes.
VW has also introduced Trendline and Highline specifications across its Transporter and Caddy line-ups to offer customers better value for money.
The brand claimed the Caddy Trendline gets kit worth £1555 but costs just £900 more than the standard model. Extras include Bluetooth, an upgraded CD/radio with ParkPilot display, cruise control, electric windows and a height adjustable passenger seat. Externally Trendline adds wheel trims, body-coloured bumpers, door mirrors and door handles.
The Caddy Highline costs £1900 more than the standard model but gets £3245-worth of additional specification, according to VW. On top of the Trendline enhancements this includes Climatic air-conditioning, leather covered steering wheel and gear stick, alloy wheels, front fog lights and an alarm.
For the Transporter, the Trendline panel van has a premium of £1100 over the standard version but delivers savings of £750 against the value of the added specification.
The step up from Trendline to Highline costs £1100. Compared to the standard model, VW claimed customers get £3595-worth of extra kit on the flagship for just £2200. All prices exclude VAT.
