The 730Ld builds on the standard-wheelbase specification with self-levelling rear suspension, chrome rain channels in the roof, illuminated interior rear vanity mirrors and an electrically-powered sunblind for the rear window and is powered by an all-aluminium 2,993cc straight-six cylinder diesel engine that produces 183kW at 4,000rpm.
This long-wheelbase specification can be further enhanced with optional multi-adjustable Comfort Seats for both front and rear seat passengers which are complemented by individually heated and air-conditioned seats and, in the rear, are available with an optional massaging capability.
Two levels of rear entertainment package completes the initial bespoke passenger experience. The BMW Business package comprises twin adjustable 8-inch flat screen monitors with a remote control while the higher specification BMW Professional system comes with 9-inch twin flat adjustable monitor screens, twin wireless headphones and is operated by an iDrive controller in the rear armrest.
A peak torque figure of 540Nm is attained from 1,750rpm through to 3,000rpm and is put to the wheels via a six-speed automatic transmission. This results in a zero to 100km/h time of 7.3 seconds and a top speed of 246km/h. Emission and fuel consumption figures are also class-leading for conventionally powered luxury cars.
The 730Ld also features double-wishbone front suspension with an all-aluminium five-link rear arrangement that is self-levelling and offers variable damping. Dynamic Stability Control, Hill Start Assist, Dynamic Traction Control, Brake Drying, Brake Pre-Tensioning, Soft-Stop and Brake Fade Compensation are also offered as standard.
The BMW 730d and 730Ld are predicted to account for 85 per cent of all 7 Series sales in the UK during the year ahead.
