What is VW BlueMotion & Will it Save me Money

What is Volkswagen BlueMotion, how does it work and will it save you money at the fuel pump?

VW BlueMotion Technology     

Volkswagen BlueMotion is a combination of 4 or 5 technologies, designed to increase fuel economy and reduce emissions, which together are known as BlueMotion:

  • Start/stop technology – the engine is automatically turned off when the car’s not moving.
  • Brake energy recuperation – the energy lost when you brake is recycled and used for acceleration.
  • Low rolling resistance tyres –reduced the friction between the tyre and the road means less energy is used.
  • Aerodynamic styling – tweaks are made to the styling, which improve the car’s aerodynamics.
  • Turbocharged engines – more power, but only when needed; ordinarily less power and lower fuel consumption.

What is VW BlueMotion?

When it comes to buying cars there are so many different trim levels and variants that you could become totally bamboozled. Some trim names refer to extra spec on the car, some refer to the ride and some, like BlueMotion, refer to the serious matter of increasing fuel economy.

BlueMotion is not one single thing, but is a combination of four or five different technologies, which together make a Volkswagen BlueMotion vehicle more fuel efficient.

What Is Start/Stop Technology?

If your engine’s not running then it can’t be using fuel. That’s the simple thought behind start/stop technology. Now, of course, most of the time we’re on the road, we need our engine to be running, otherwise we wouldn’t get very far! However, there’s also a lot of time when our engine doesn’t actually need to be turning over.

On your usual commute to work or the school run, for example; how much of that journey do you spend stationary, at traffic lights, at a busy junction, sitting in a queue? Sadly, the answer is quite a few minutes, minutes when your engine doesn’t need to be running and that’s what the stop/technology does, stops your car’s engine running once it’s stationary, saving you fuel and cutting exhaust fumes for pedestrians.

It’s a win-win technology and forms part of Volkswagen BlueMotion.

Brake Energy Recuperation

No matter how carefully you drive to try and conserve fuel, you still need to brake, when you’re stopping at a junction or traffic lights for example.

Braking usually means lost energy, but the Brake Energy Recuperation system stores and then recycles that energy via the car’s alternator. What’s an alternator; well it’s the gizmo that charges your battery from the engine.

The recycling works by raising the voltage of the alternator when you’re braking and then, when you’re setting off the alternator voltage is lowered, which in turn lightens the load on your engine and cuts fuel consumption.

It’s clever stuff and it works.

Low rolling resistance tyres

These are special tyres designed to reduce the friction between the tyre and the road. Doing this means it takes less energy to start the wheels turning and less energy to keep them moving as friction remains lower.

It’s very simple, but it saves fuel when you are moving off from a standstill and when you’re cruising on the motorway.

Aerodynamic styling

The more aerodynamically designed a vehicle is, the less drag there is, meaning better fuel consumption and more money saved.

BlueMotion vehicles have extra attention paid the bodywork, to ensure there’s a little drag as possible.

The tweaks include narrowing the gaps between the body panels, which helps to make the whole body more streamlined. Light units are designed to contain both the headlights and indicators.

Underbody panels, spoilers and grilles and all designed with the specific aim of reducing drag. BlueMotion can also include lowering the ride height of the car; all these aerodynamic tweaks lead to decreased drag, which means less fuel used.

This is a, in a way, an optional extra when it comes to BlueMotion, but there are good reasons why, if you want to maximise your fuel consumption, you might want to consider a turbocharged engine.

Some of us may think that if an engine is turbocharged, that equals a gas-guzzler, but, you’d be wrong. The use of turbocharged engines as part of the Volkswagen BlueMotion technologies package is designed to do the exact opposite by delivering increased power only when you need it and a less powerful, less fuel intensive engine when you don’t.


Will BlueMotion save me money?

As with many things fuel related, the answer is in the number of miles you cover annually. If you’re a low mileage driver or even an average mileage driver, the sums may not add up to you saving money, though you will be using less fuel and helping the planet.

This changes if you’re a high mileage driver, when the chances are BlueMotion will save you money.

However many miles you cover, BlueMotion will mean you spend less time standing on a garage forecourt filling your car up, which with our usual weather, means less time standing in the wind and rain!
