Slow down test
IPE off 10 and you could save $10,000 a year.
Scania says reducing maximum cruising speeds from 100km/h to 90km/h could result in massive savings for interstate heavy haulers in Australia.
It has just completed a real world test using two of its top-line R560 V8s running as b-doubles of 59 tonnes GCM (the total weight of the truck and its load), driven over 1536km.
Running from Melbourne to Sydney, one truck ran with its speed limiter set at 100km/h while the other was limited to 90km/h. The roles were reversed on the return leg to ensure consistency.
Scania found that the truck travelling at 100km/h used 45 litres more fuel on its way from Melbourne to Sydney than the 90km/h truck. The numbers were 494 litres versus 449 litres.
The gap was not so great on the return journey to Melbourne, with the faster truck using 11 litres more than the other vehicle, with fuel consumption of 486 litres versus 475 litres.
Scania points out that an operator running the truck between Melbourne and Sydney five times a week with a limit of 90km/h instead of 100km/h could save $10,000 on every truck every year.
