All the abovementioned cars will feature a new M Performance TwinPower triple turbocharger engine. It will be a 3.0 litre six cylinder turbodiesel which generates around 381bhp and 740Nm of torque. 0-100km/h timing will be around 4.7 seconds and will have a electronically limited top speed of 250km/h. BMW didn’t say much about how the set-up looks like or how the third turbo will play a part in the set-up.
Just days after BMW’s announcement, a patent application for a triple turbocharger set-up by Porsche was revealed. It is said that this set-up will be used on the new Porsche 911 Turbo. It is clear that Porsche is seeking to increase the overall power, low-end response and efficiency of the 911 (991) series.
Porsche has used a twin turbo set-up since the 911 (993) series and that improved the car’s performance since the older Turbo models display an extreme turbo lag characteristic. Since both the 911 (991) and the engine are still in the developmental stage, nothing much is known about them. What is expected is a higher power output from the new engine, somewhere in the region of 550bhp for the base Turbo model.
Technically, a twin turbo set-up is better compared to a single large turbo. One turbo will spool quickly to offer better low end response and the other one will provide power at the higher end. This will eliminate the dreaded turbo lag which many single turbo car owners are familiar with.
But how will a triple turbo set-up function? For that we will have to wait and see how it turns out.
