Volkswagen Commercial Vehicles has revealed its fourth generation Caddy before the new model goes on sale in the UK in the second half of the year.

The new model will come with a selection of Euro6 and Euro5 diesel engines with power ranging from 75hp to 150hp. The Euro5 engines will be phased out when Euro6 technology becomes mandatory in September 2016.

All Euro6 engines will be 2.0-litre powertrains already in use on VW’s passenger car range and, aside from the most frugal Bluemotion unit, all will feature Bluemotion Technology as standard. The most powerful model will be the 150hp version.

The Euro5 line-up will continue to feature the 1.6-litre TDI with outputs of 75hp and 102hp as well as the 140hp 2.0 TDI.

While final UK specifications and efficiency figures are not available, VW is expecting the new generation Caddy Bluemotion to return over 70mpg. The most efficient Caddy currently on sale is the 119g/km 1.6-litre diesel Bluetmotion.

The mark4 Caddy will be available with a range of transmissions comprising of five or six speed manual ‘boxes and six and seven-speed DSG systems.

The Caddy will come with city emergency braking, multi-collision brake as standard, as well as side and curtain airbags. Optional extras include a driver alert system, which prompts the driver to take a break and a heated windscreen to help clear ice and de-mist.

The Caddy will also be available with adaptive cruise control for the first time that, when paired with a DSG gear-box, can slow the vehicle down in queues of traffic to a complete stop. Van drivers will also be able to spec a reversing camera, satellite navigation and an assisted parallel and reverse-bay parking system.

UK specifications and pricing will be announced closer to launch in the third quarter of this year but initially the line-up will not include the four petrol engines that VW will launch in other European markets. UK boss Carl zu Dohna says these drivetrains, consisting of a 1.0, 1.2 and a pair of 1.4-litre engines could follow later depending on demand.

The new Caddy will continue to be offered in two body lengths – the standard van has a wheelbase of 2681mm while the Maxi extends to 3006 mm. Load volumes are likely to remain at 3.2m3 and 4.2m3 respectively but VW claims the top payload will increase to 832kg – compared to the current maximum of 767kg.

Volkswagen describes the new Caddy as an evolution on the current Mark3 model with sharper lines and more clearly defined surfaces to both the front, which features a new badge, grille and headlights, and rear, which can be ordered with a windowless tailgate and roof spoiler.

The new Caddy will continue to be built in Poznan, Poland – the van’s home since 2003. VW sold 1.5 million third generation Caddy models in its 11 years of production.

While acknowledging that “we take all competitors seriously” zu Dohna adds: “The Caddy is the class leading product.”
