BMW is a long history of using turbochargers technology.
In its highest form of Motorsports but the leg often associated with this technology is too much of a compromise for our legendary driving performance on the road.
You will notice that we are introducing turbo charging technology on all of our new engines.
So how do we reconcile this concern of turbo lag? Well we completely redesigned the turbo from the ground up.
The secret to reducing turbo lag is in the turbocharger unit itself, while using two inlets and two Scrolls we are able to make sure that the turbo is available whenever you need it.
BMW twin power turbo gives you increased efficiency and more performance but it doesn’t sacrifice or compromise between the two.
So now you have the best of both worlds a small efficient engine for your daily driving needs but all the torque you need to get you off the line and for passing manoeuvres.
When you consider how BMW TwinPower Turbo technology allows us to build engines that perform beyond their weight and their size while improving fuel efficiency, you can see why turbo charging technology will play a bigger role in our future engine lineups you.
Engine power and torque is proportional to the amount of air and fuel that enters the engine cylinders.
If we want to produce more power the engine will require more air to be delivered into the cylinders.
Turbo charges are added to a vehicle’s engine to increase its performance and torque output allowing manufacturers to decrease the engine capacity.
One downfall to this design is that once turbocharged the engine may experience a phenomenon known as turbo lag.
Turbo lag is the amount of time that it takes for the turbocharger to spool up before it starts creating boost pressure in the intake manifold.
Turbo lag varies from model to model and is also dependent on the type of turbocharger that the manufacturer has chosen.
A large turbocharger will produce large torque figures but take a longer time to spool up than a smaller turbocharger creating a very noticeable lag in torque delivery.
A small turbocharger would spool instantly with very little to no lag but would drastically reduce the amount of torque the engine could produce.
This is one reason why vehicle manufacturers often compromised on the size of the turbo fitted to their engines.
There are many different ways around this problem, like using twin turbos VGT technology or even twin-scroll designs as with BMW.
