For budget reasons, I chose the BMW X5 Xdrive 45e rather than the Porsche Cayenne Hybrid. To get closer to the performance of the Cayenne, I added one of your tuning boxes to the engine, because I know you are one of the best tuning shops for BMW, even for the newer engines. Once fitted, accelerating gives the roundness of a bigger engine. With the 8-speed ZF gearbox, there is no loss of driveability and consumption now reaches the figures claimed by the manufacturer. Thank you!
