Why would the high RPM necessarily mean using a lot of fuel? I've had a little VW Polo 1.0L that used to sit at 4000rpm just to go 70mph on the motorway, and it still returned like 50 imperial mpg(~6L/100km).
- alistairSH 3y agoMost Toyota Siennas were delivered with a 3.5L V6. The earliest models had a 3.0L. And they usually have an idle RPM around 700-800rpm.
- rightbyte 3y agoEssentially you want the motor to makes as few turns as possible for the same power output. At some low rpm the burn cycle gets bad though. Depends on motor. Fuel effeniency charts need constant power lines to be useful or they fool people.
