 While the "K2 Sherpa"s engine remained available (including the ancient B-series diesel), a 2.5-litre diesel unit was now offered on the 300 Series.Following the completion of a special police contract, the Rover 3.5-litre V8 unit also became available from 1986, and immediately became popular with emergency services and express delivery operators.However, with the merger of Freight Rover, along with the rest of the Leyland Trucks division of the Rover Group with DAF Trucks the following year, to form the new DAF NV and Leyland DAF companies, the Rover Group ceased to be a player in this sector of the light commercial market.
