ROLLS-ROYCE thinks that the high power outputs.

The company bases this assumption on a number of factors which include an increase in gross weights. It is the Rolls-Royce view that the main vehicle operating weights will be at 31/32 tonnes, 35/36 tonnes and 38/ 40 tonnes with a possible requirement of up to 44 tonnes.

According to Rolls-Royce's marketing manager, Alan Howell, the legislated powerto-weight ratio is likely to be 5kW/tonne (6.8bhp/ton) with the actual power requirements being 160kW (214bhp) at 32 tons, 180kW (241bhp) at 36 tonnes, and 200kW (286bhp) at 40 tonnes — all nett installed outputs.

In anticipation of such a change the company argues that the forward-looking haulier should be encouraged to look at 290 horsepower as a serious purchase during 1980. Another argument put forward for higher power is the full implementation of drivers' hours legislation and the tachograph. In the words of Alan Howell, "the last months of 1980 will need a searching look at driver productivity. The ability to maintain high average speeds whilst taking note of legal limitations points clearly towards a little more power." In line with this thinking, Rolls-Royce has increased the warranty of its 290L engine to two years with unlimited mileage. According to the company's marketing director, George Reeves, "experience tells us we are in a position to do it".
