Re: Revised FAQ
Calculated mileage - How accurate are the dashboard calculations?
- Typically the MPG displayed is 1-1.5 MPG high. The fuel usage is an approximation, so it would be difficult to calculate an accurate MPG.
- The speedometer is approximately 3 miles per hour high at 60 miles per hour (see this post for details)
- What mileage are other drivers getting?
- This page lists the various users mileage. Please don't expect to be able to achieve the mileage that some users are posting. You may not be able to, nor want to, drive under the conditions that they did to achieve these results.
- How do I interpret the graph on the ECO Drive Display (one of the screens inside the speedometer) and the blue rings that, at times, appear around the speedometer?
- The ECO Drive chart shows the car's approximate average mpg since you last started the car (it resets every time you turn the car off). It is a stair step display and is updated every 10 seconds.
The rings may appear on the outside of the speedometer as your mpg improves. The gauges change luminosity and more rings are added at the same time as the ECO Drive stair step increases. The following are the levels of the stair steps and corresponding blue speedometer rings:- Level 0 -- Below 25 mpg -- Ring brightness off, no lines
- Level 1 -- Between 26 & 30 mpg -- Ring brightness is subtle with one thin blue line
- Level 2 -- Between 31 & 35 mpg -- Ring brightness is medium intensity with thicker blue lines
- Level 3 -- 36 mpg & above -- Ring brightness is full intensity with the thickest blue lines
When you turn off the the car, the ECO Drive display (MFD) retains the ECO display for 3 seconds. It will display "EXCELLENT" if your average was 36 MPG or more. Remember, these are approximations of your mileage.
The ECO display on the dash is not related to the ECO switch next to the tank refill switch referred to in this post.
