Active Rollover Protection (ARP)

As part of the ESP system, Active Rollover Protection (ARP) recognises an impending rollover and rapidly applies braking to selective wheels to reduce the likelihood of it happening. Especially useful on a vehicle with a high centre of gravity such as a van. ARP detects excessive lateral force if, for example, a van is driven too fast into a corner, which could cause a rollover.

Most Add Ons include a two year warranty. And if you order and fit them at the time of purchasing a new vehicle, we may be able to extend that to three years to match your vehicle's warranty. Take a look at the full range of Accessories.

Anti-Lock Braking

It can be very challenging to stop a van on a slippery road. Anti-Lock Braking (ABS) takes the effort and stress out of this situation. The theory is simple as a wheel that is locked and skidding has far less grip that a wheel that is not. So ABS stops the wheels skidding while you slowdown, which means you actually slow faster and can still steer as you come to a stop.


BlueMotion Models

A van with the BlueMotion badge is a true hero of the range. In addition to being equipped with all of the BlueMotion Technologies, its design and specification has been optimised to reduce weight and improve aerodynamics. And for you, that means impressive fuel efficiency. For example the Transporter BlueMotion has a 48.7mpg (combined), which is 8mpg better than the next most fuel-efficient model in the Transporter range.

BlueMotion Technologies

BlueMotion Technology, consisting of cruise control, low rolling resistance tyres, regenerative braking and Start/Stop, is available on most models across the Volkswagen Commercial Vehicles range.


As well as safeguarding your goods, the addition of a bulkhead will protect you and any passengers from the danger of loads shifting too far forward when you brake.


Daytime Running Lights

Daytime running lights offer extra safety. Fifty per cent of all daytime accidents at junctions are caused by drivers not seeing other road users in time. Road safety experts recommend switching on dipped-beam headlights during the day, or the use of additional daytime running lights. For extra driver convenience, our dipped-beam headlights are automatically switched on when you start your vehicle.

Diesel Particulate Filter (DPF)

The Diesel Particulate Filter (DPF) system removes particulates from diesel exhausts, making a major contribution to the reduction of particulate contaminants in the environment.

Double cab

Sometimes you need room for all your equipment and your crew, which is where our double cab vehicles come in. Our Crafter double cabs have seven seats and a longer wheelbase


If you prefer open spaces and open vans, a Transporter or Crafter Dropside is for you. Power and comfort join forces with build quality and flexibility to make this a winning combination. Simply choose the wheelbase that works for you.

Dual Clutch Gearbox (DSG)

Our acclaimed 7-speed dual clutch direct shift gearbox (DSG) has two clutches and can be used as a fully automatic gearbox, or as a responsive quick-shift manual. The innovative dual clutch system not only facilitates an instant gear change, but can aid fuel consumption, whilst also helping to maintain swift and smooth progress. Find out more


Electronic Brake Assist (EBA)

Electronic Brake Assist (EBA) helps prevent the rear-end from breaking away under heavy braking by ensuring maximum braking performance at both the front and rear wheels. Brake 'fading', as a result of overheating, is also counteracted.

Electronic Brakeforce Distribution (EBD)

Electronic Brakeforce Distribution (EBD) helps prevent the rear-end from breaking away under heavy braking by ensuring maximum braking performance at both the front and rear wheels. Brake "fading", as a result of overheating, is also counteracted.

Electronic Differential Lock (EDL)

Electronic Differential Lock (EDL) uses ABS sensors on the driven wheels to determine if one wheel if spinning faster than the others. It uses the ABS system to momentarily apply braking to balance out the traction needs of the driven wheels. Front-wheel drive vehicles usually have the most recognisable feel, as they produce the typical ABS-type pulsating sound and feel when they're activated during a wheel spin.

Electronic Stabilisation Program (ESP)

ESP improves a vehicle's stability by detecting and reducing loss of traction (skidding) when ESP detects loss of steering control, it automatically applies the brakes to help "steer" the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter over steer or the inner rear wheel to counter understeer.

Emissions Standards

European Union (EU) legislation sets out exhaust emissions standards for new vehicles sold in the EU. They govern the limits on pollutants emitted in vehicle exhaust gas (sulphur dioxide, nitrogen oxides, hydrocarbons, carbon monoxide, carbon dioxide and diesel exhaust particulates). New model types may now be approved to the Euro 5 standard and are compulsory for all new vehicles from January 2011. From September 2015 all passenger carrying vehicles must be registered as Euro 6 and Commercial vehicles in September 2016.

A single vehicle representative of a particular vehicle is tested, either by independent test organisations, or by the manufacturers or importers and the results verified by the DfT. Volkswagen is currently working on the development of vehicles to meet Euro 6 standards, currently on Crafter there are two Euro 6 engines available.

Engine Braking Control (EBC)

Engine Braking Control (EBC) prevents the driven wheels from locking owing to the braking effect of the engine when the accelerator pedal is suddenly released, or the vehicle is braked with a gear engaged.

Enhanced environmentally friendly vehicle (EEV)

Enhanced environmentally friendly vehicle (EEV) is a term used in the European emission standards for the definition of a clean vehicle. The standard lies between the levels of Euro 5 and Euro 6. Our Crafter is certified as an EEV enhanced environmentally friendly vehicle.

Engineered to go (ETG)

Our ETG program allows for more bespoke vehicle solutions. We work in partnership with leading conversion specialists to create high quality and durable Dropside, Tipper and Luton variations.



Our Transporter kombi has been designed with practicality, flexibility and comfort in mind. With five or six seat options, there's plenty of room for you, your crew and equipment. And you can choose from four TDI engines, two wheelbase lengths and three roof height options. Not just a great people carrier, the kombi holds its own on the road.


Passive Safety

Passive safety refers to measures that help protect the occupants against injury or help reduce injury severity in the event of an accident. Passive safety measures include the safety belt system, the airbags*, the rigid occupant cell and the crumple zones at the front of the vehicle. Safety features built into the body, front and rear, help to dissipate most of the impact energy. All these elements help to provide excellent all-round protection.

* Airbags are supplemental restraint systems only and will not deploy under all accident circumstances. Always use seat belt and child seating appropriate for their size and age. All child seating must satisfy the current legislation standards.


Payload is related to gross vehicle weight. Payload capacity is the weight the vehicle is able to carry but does not include the weight of the vehicle itself.


When you need a hard-working pick-up with power and intelligence, you'll find the perfect combination in our Amarok.


Start-stop system

The start-stop system increases fuel economy and lowers harmful emissions. If, for example, you come to a standstill in a traffic jam and take your foot off the clutch, the engine automatically switches itself off. Simply depress the clutch pedal to move off again. The start-stop system is one of the efficient and environmentally compatible technologies offered by Volkswagen under our BlueMotion Technologies.



Volkswagen has many years' experience in TDI technology. Characteristic features of the TDI engines are fuel economy, low emissions, high pulling power (torque) and outstanding power efficiency.


With a tough steel platform, one tonne load lashing points and an Ingimex Titan tipper body, our robust Crafter Tipper is hard to beat, whatever you need to offload.

Traction Control System (TCS)

Traction control helps to limit tyre slip under acceleration on slippery surfaces, thus helping the driver to retain proper control. Using sensors at each wheel, the system recognises when traction has been lost and momentarily applies braking to that wheel to help it regain grip. Traction control does not increase traction though; it simply attempts to stop a vehicle's wheels spinning. In some vehicles TCS is also known as ASR.



The 4MOTION® all-wheel drive system reduces wheel spin in adverse conditions such as rain, snow, mud or gravel. It reacts to wheel spin in just milliseconds, sending power to the wheels with most grip, so ensuring better road holding and improved safety. Find out more
