BMW has added the world’s most powerful production six-cylinder diesel engine, the potent twin-turbo 3.0L six, to its SUV range with the introduction of the new X5 3.0sd. The motor provides the driver with 286hp and a flat torque curve with a peak of 580Nm from a low 1,750rpm. This enables the diesel SUV to accelerate from 0 to 62mph in seven seconds and reach a top speed of 146mph.

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.

Now, please, tell me that LeMans blue will be available for X5 too and that's it - that's my car, with either Aero or M package, but rather Aero if IRL MN package doesn't impress me enough like Aero.

and yes, the best X5 out there at te moment. Or should I say best SUV

Both!

Motor authority doesn't know the difference between a drivetrain and a powertrain.

This is easily the best X5, but whether it's the best SUV is debatable given the highly subjective criteria by which SUVs are classified and measured.

The best SAV? Of course...

Tyc, I see you in one of these my brother - a nice deep blue with a richly opulent and nicely toned interior.

Damn right!

8 months to go, it's long, but worth. Hopefully my dealer will finally get one for test drives...
