The drivetrain in the BMW X5 3.0sd is unique in its segment as it utilizes two differently sized turbochargers operating sequentially. The turbos deliver a constant 2.85bar of boost, which gives the driver linear power delivery and helps provide a flat torque curve. One smaller turbocharger provides near instantaneous power at low engine speeds, while a larger turbocharger provides the mid to top end power, all controlled by the vehicle’s ECU.
Power is transmitted to the road via a standard six-speed automatic gearbox and BMW’s xDrive 4WD system. To go with the extra power, BMW has uprated the brakes by fitting thicker and larger diameter disc brakes over the base X5.
The diesel versions also come with a chrome kidney grille with titanium vertical slats, but we think the added performance will be enough to impress your mates.
