BlueMotion fuel tech for VW Transporter

Manufacturer claims 51.4mpg combined for the VW Transporter with BlueMotion technology.

The VW Transporter can achieve 51.4mpg thanks to fuel-sipping BlueMotion tech, according to the VW Group. The BlueMotion VW Transporter starts from £19,670 or £24,591 with VAT added and is part of a range of eco commercial options now being offered by Volkswagen.

The short wheelbase VW Transporter T6 has a 2.0-litre 102bhp diesel engine under the bonnet. This is matched with a five-speed manual transmission and VW claims economy of 51.4mpg for a combined cycle and emissions of 145g/km. The greenest specification of the VW Transporter previously available returned an additional 3.5mpg and produced 8g/km more CO2.

Aerodynamics are key to efficiency in VW Transporter

The efficiency improvements have been achieved through a variety of aerodynamic refinements which Volkswagen has made to the VW Transporter. The work included the addition of low-rolling resistance tyres, and a lowered suspension. Cruise control and modified gear ratios are further additions, together with battery regeneration systems and a stop/start system to save fuel.

VW is joining other manufacturers in bringing out an eco take on a van. Vauxhall has bought out an ecoFLEX Vivaro, for example, although this does not offer the same level of efficiency as the VW. The green ecoFLEX Vivaro produces 155g/km in CO2 emissions and delivers 50.4mpg.

VW BlueMotion Technology explained

BlueMotion Technology includes three main functions: a start/stop system; low rolling resistance tyres; and regenerative braking to lower fuel consumption. This reduces CO2 emissions and improves fuel efficiency, something that can be particularly important in commercial vehicles which need to maximise profits whilst minimising environmental impact. And they must clearly offer a reliable means of transport.

The start/stop function in the BlueMotion VW Transporter allows fuel to be saved by automatically turning off the van’s engine and engaging neutral when it stops. When it is time to move again, the engine starts automatically. In vehicles with automatic transmissions, meanwhile, the system deactivates the engine when the driver uses the brake and pressing the accelerator reactivates it.

Low rolling resistance tyres mean that less power is needed to get the van moving and to keep it rolling. This can be particularly useful when a VW Transporter, for example, is filled with a heavy load as it reduces the work of the engine and helps with minimising fuel consumption.

Regenerative braking is based upon the idea that vehicles aiming to save energy should attempt to recover as much of it as possible. Regenerative braking means that the energy which is usually lost as a result of braking is, instead, stored. This can then be used in starting or accelerating the van.

The most efficient in the range

BlueMotion Technology or BMT is now available on the majority of models in the Volkswagen Commercial Vehicles range. The company also offers what it calls ‘flagship BlueMotion models’, which include the Caddy BlueMotion. This is the most fuel-efficient van in the range, boasting the lowest emissions and available at a starting price of £16,287 before VAT.

The Caddy has a standard wheelbase and a 549kg maximum payload. It’s maximum load length, meanwhile, is 1,779mm, catering for loads of up to 1,556mm wide and up to 1,244mm in height. The Caddy has a new EU6 engine and VW claims it can deliver 65.7mpg combined with CO2 emissions of 114g/km.

The Caddy is the only model in the BlueMotion range to feature Hill Hold Assist. This aims to make moving off whilst on a hill smoother and more efficient. It is achieved by holding on the van’s brakes for a short while, removing the need for the driver to rev the engine in the manner commonly seen in hill starts.
