Performance Tuning for BMW Plug-in Hybrid and BMW Mild Hybrid models
A BMW plug-in hybrid electric vehicle (PHEV) like the BMW 320e Touring G21, BMW 320e xDrive Touring G21, BMW 330e Touring G21 or BMW 330e xDrive Touring G21 is a BMW whose battery can be charged by connecting to an external power source as well as by its board motor and generator, this we all know.
BMW mild hybrid models, however, do not have a purely electric drive. Here, the electric motor offers greater efficiency by replacing the starter and alternator with a single device that supports the drive train.
Choosing a plug-in hybrid BMW can improve the efficiency and you get Federal Tax Credits for New All-Electric and Plug-in Hybrid Vehicles like the 2021 BMW 320e Touring G21, BMW 320e xDrive Touring G21, BMW 330e Touring G21 or BMW 330e xDrive Touring G21.
Do these findings mean that you shouldn’t tune or upgrade a hybrid vehicle?
You have to have driven a performance-enhanced BMW plug-in hybrid or Mild Hybrid model!
Driving a performance enhanced BMW plug-in hybrid like the BMW 320e Touring G21, BMW 320e xDrive Touring G21, BMW 330e Touring G21 or BMW 330e xDrive Touring G21 is more fun than a conventional BMW 320i or 330i thanks to the additional electric motor. The tremendous power development of both drives pushes the driver into the seat.
Specialized in BMW plug-in hybrid performance enhancements
For many years, we have been testing and developing engine performance tuning solutions for BMW plug-in hybrid models and have had some positive experience. You could say that we have specialized in performance enhancements for BMW plug-in hybrids.
With the latest generation of BMW mild hybrid cars, we got the same positive results when it comes to tuning the engine performance.
Since only the power of the gasoline engine of the BMW plug-in hybrid or BMW mild hybrid is increased and both systems work independently of one another, there have been no disruptions in daily driving so far.
The BMW TwinPower Turbo engine in combination with an electric motor and our engine performance tuning offers more power, range and efficiency for your daily journeys.

BMW 3-series Touring G21: Chassis Tuning
Body parts such as sets of exterior M style mirror caps in high-gloss black or real carbon, a front splitter, and kidney grilles in different versions are available for the BMW 3-series Touring G21.
Learn More - Why to add a Front Splitter
Why to add a dAHLer Front Splitter?
Aerodynamics is the study of how gasses interact with moving objects. The two basic aerodynamic forces are drag and lift.
A lot of rear downforce itself can cause understeer and no one wants that. It would help to balance things out to add downforce to the front tires using a front splitter.
When a front splitter is added, it increases the amount of area, air can stack up against while helping more of it move over the car. Now with more pressure on top and lower pressure underneath you’ve got a net downforce on those front tires.
