The Porsche 911 and radical changes simply can’t be placed in the same sentence. And yet, after five decades of steady evolution, we are about to see one of the greatest tuns in the Neunelfer’s history, the turbo revolution.
The 991 generation’s mid-cycle revamp, which is just around the corner, will bring turbo models outside the Turbo models for the first time. Having forced-fed Carrera and Carrera S 911s will obviously change the character of the cars, so how does Porsche cope with this?

For one thing, the 911 facelift models will offer a Sports Response Button (SRB). This will allow the driver to choose between four modes that alter the throttle mapping and reduce turbo lag, as Autocar, which has been given a shotgun ride in the prototypes, writes.

You’ll get to choose between O, S, SI and I - For instance, S will be used for highway driving, while SI for track time, whereas the I mode, which stands for Individual, will allow you to make your own configuration.

We’re not sure whether this means the rumors about the variable compression ratio are closer to the truth, but it seems so. After all, such a parameter would only allow these modes to make a greater difference.

Variable Compression Ratio

We’ll remind you Porsche is currently working to develop variable compression ratio turbocharged petrol engines, but we don’t know if the development will be introduced on the 911 facelift or later on.

Regardless, the tech goodies will allow the engine to reduce turbo lag and improve efficiency, while ultimately giving it a wider power band, which brings it close to the power delivery of an atmospheric engine.

It will be interesting to compare Porsche approach to Ferrari’s one - Maranello has now returned to turbocharging, with the California T and the 488 family. The Prancing Horse relies on variable boost, reducing the psi in the lower gears in the attempt to mimic the linear power delivery of an atmospheric engine.

The Porsche 911 mid-cycle revamp will show up at the Frankfurt Motor Show in September, so you’ll be able to take the kids to school in SI mode soon.
