A BMW 6 Series GT is a seriously pleasant bit of kit, and the latest one to land in Australia has the added appeal of using fuel at the super eco rate of just 5.4L/100km.

How come?

Well, it has a 2.0-litre turbo-diesel under its fair snout and sends its 140kW and 400Nm to the back wheels via an eight-speed auto cogbox.

Also, the 620d costs less than $100,000. You can have one for $99,900, but that’s before on-road costs.

The new variant lifts the 6 Series Gran Turismo line-up to three models, the other petrol-driven cars being the 630i and 640i xDrive, priced at $123,500 and $148,529, respectively.

The 620d doesn’t lack for standard equipment and comes with the brand’s Luxury Line kit, plus leather upholstery, rear air suspension, a panoramic glass sunroof, adaptive LED headlights, 19-inch light alloy wheels, an automatic tailgate, head-up display and vast range of electronic aids.

Among them are Driving Assistant Plus, which includes Active Cruise Control with Stop&Go function, front and rear Cross Traffic warning, Evasion Aid, Steering and Lane Control Assistant, Rear Collision Prevention, Lane Keeping Assist with Active Side Collision Prevention and Crossroads warning.

Another goodie is Parking Assistant Plus, which enables Automated Parking, with Surround View cameras, so you can keep the bumpers away from lesser machinery in tight parking spaces.

The stylish car also has Dynamic Stability Control, ABS with Brake Assist, Cornering Brake Control and Dynamic Traction Control and several dozen more features.

However, no car of such stature is immune from the inevitable option packs, and for the 620d buyers can choose from the M Sport, Exclusive, Comfort or Innovations packs.

“The BMW 6 Series Gran Turismo has been well received for its combination of luxury, interior space, performance and efficiency,” BMW chief Marc Werner said.

“The 620d looks elegant with the standard Luxury Line, while providing a step-up in specification and space over the 520d.

“It’s a fantastic introduction to the 6 Series Gran Turismo range.”

Its 2.0-litre turbo diesel four-cylinder engine is said to “meld performance, response and efficiency seamlessly.”

It can take the car from zero to 100km/h in 7.9 seconds, but its fuel economy of 5.4L/100km will be of greater importance in our “speed kills” government logic. The fuel use figure was achieved in Europe and has to be confirmed for Australia.

The 620d GT, which “provides a smooth, response-rich driving experience” the company says, will be in showrooms in October.
