instead. The Rover V8 engine was fitted in the engine bay. The three-speed automatic gearbox was the BorgWarner 65 model. The dashboard of the SD1 features an air vent, unusually, directly facing the passenger. The display binnacle sits on top of the dashboard in front of the driver to aid production in left-hand drive markets, since it avoided the expense of producing two different dashboard mouldings for LHD and RHD versions. The air vent doubles as a passage for the steering-wheel column, and the "podular" display binnacle can be easily fitted on top of the dashboard on either the left or right-hand side of the car. This concept was not entirely new; it had also been used on the Range Rover and was used again on the Mk.1 Austin Metro, both of which were also designed by David Bache. The interior of the Series 1 was notable for its lack of wood embellishment in comparison to previous Rover saloons, with an extensive use instead of modern soft-feel plastics, and a new "skeletal" version of the Rover badge would appear on the bonnet - Bache was keen that the SD1 should make use of the latest industrial design trends and be a clean break from the past. An estate body had been envisaged, but it did not get beyond the prototype stage. Two similarly specified estates have survived, and are exhibited at the Heritage Motor Centre and the Haynes International Motor Museum respectively. One was used by BL chairman Sir Michael Edwardes as personal transport in the late 1970s. The two cars as befit prototypes differ in the detail of and around the tailgate. One car has a recessed tailgate, while the other has a clamshell arrangement, where the whole tailgate is visible when closed. The SD1 was intended to be produced in a state-of-the-art extension to Rover's historic Solihull factory alongside the TR7. It was largely funded by the British government, who had bailed BL out from bankruptcy in 1975. Unfortunately, this did nothing to improve the patchy build quality that then plagued all of British Leyland. That, along with quick-wearing interior materials and poor detailing ensured that initial enthusiasm soon turned to disappointment. Series 1 (1976-82) This car was launched on its home market in June 1976 in hatchback/fastback form only, as the V8-engined Rover 3500: SOHC 2.3 L and 2.6 L sixes followed in November 1977, when the
