EPA rating is performed at lower rpms, shifting at the optimum point for fuel savings. Likely nobody who owns a sports car drives like that on a regular basis.

 

13MPG? should be more like 9.

 

22 mpg. 240 Hwy miles from SC to GA after delivery. Kept under 4k

 

I'm getting 18mpg in the city.

 

I continually get 21 mpg in a mix of city, rural, and highway, but bear in mind I'm keeping between 2k and 4.5k rpm until I hit a thousand miles. Having said that on the highway I'm continually switching gears, speeds, and RPMs as part of the break in. Speeds between 55 and 85, shifting between 4th and 6th
