Fleets running executive models will benefit from fuel-saving technology in the latest 7 Series.

Due to go on sale in the UK in November, the new Seven may look similar to the outgoing model, but it features a host of new technology including, for the first time, the company’s EfficientDynamics, which improves fuel economy and lower emissions.

The extensive use of lightweight aluminium panels, brake energy regeneration and a new, more powerful diesel engine allows the 730d to return a claimed 39.2mpg and emit 192g/km of CO2. This compares with 210g/km and 35.8 for the current 730d.

Other models to be offered are the 740i, powered by a twin-turbo 3.0-litre six-cylinder petrol engine, and the 750i featuring a twin-turbo V8 petrol.

The petrol models will also be offered in long-wheelbase form.

Elsewhere, the Seven will offer a side view camera system to aid parking, night vision, lane change warning, head-up display and a special steering system which allows the rear wheels to move by up to three degrees.

BMW expects the 730d to account for 85% of sales, reflecting its popularity in the corporate and, in particular chauffeur, market.

Pricing and specification levels will be announced closer to the car’s autumn launch.
