The real big issue is that the air will be so disrupted by these 2 areas it will never have a chance to smooth out and take advantage of any aerodynamic enhancements made to the rear of your car. It's pretty much a brick.
Very true. If you are serious about aero, Google "1969 Dodge Charger Daytona" and look at what they did to the nose.
The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.
