Exactly -- sure, you can still hide behind a truck and go 100 km/h all the time -- but most cars efficiency sweet spot is around 130 km/h, and driving at that speed leads to more dynamic, occasionally passing trucks, etc.
- gnur 12y agoWhat is an "efficency sweet spot"? When I consistently drive at the speed limit (in the Netherlands, 120km/h) I have to fill up every 4 working days. When I consistently drive 100 km/h I only have to fill up every 5 working days. Takes 20% longer but the tank also lasts 20% longer.
- gambiting 12y agoDepends on the car. If you have a tiny engine, then it will use large amounts of fuel at high speeds. If you have a large engine, it will use less. My personal experience: Peugeot Partner 2.0 HDi - 6-7l/100km when driving in city traffic, 12-13l/100km when driving at 140km/h, Land Rover Discovery 3 4.4L V8 - 15-16l/100km when driving in city traffic, 9-10l/100km when driving at 140km/h. Basically your engine should stay below 3000rpm - if you have to keep it at 4000rpm just to maintain a certain speed then it's too much for the engine and it's not being efficient.
