I get 25.8 MPG in mixed driving according to my trip computer.
That estimate is not calculated the same way that we calculate gas mileage since the trip computer computes MPG continuously and averages it.
When you lift your foot off the accelerator on the freeway, the instantaneous fuel economy goes to infinity and when you stop and idle it goes to 0.
I stop at idle a lot more than I coast on the freeway, so my trip computer determines an average lower than we do by dividing how many miles we drove on a certain amount of gas.
When I compute my fuel economy the traditional way, I get 28 MPG in mixed driving, and that is on my first tank.
When I reset my fuel economy calculator in the car with the cruise on at 75 MPH, I get 33 MPG according to the car, which I trust to be accurate since there are no infinity readings or 0 readings averaged into the mix.
If you ask me, 33 MPG at 75 MPH in a 3300 lb car with the ability to do 0-60 in 8.5 seconds is pretty impressive.
The Solara is a nice piece of engineering.
