Car Mileage

  1. 1. Factors Affecting Car Gas Mileage<br />Cody Kustrin<br />Weston McCollum<br />
  2. 2. Purpose<br />What Factors affect car mileage and to what extent?<br />Factors Examined<br />Drive Type<br />Gas Type<br />Weight<br />
  3. 3. Data<br />122 Cars<br />70HPToyota Prius to the 285HP Chevy Suburban<br />Drive type<br />Front (1)<br />Rear (2)<br />AWD (3)<br />Gas type<br />Regular (1)<br />Premium (2)<br />Diesel (3)<br />Weight<br />2150 lb. Acura MDX to the 7270 lb. Ford Excursion<br />
  4. 4. Drive Type<br />
  5. 5. Analysis of Drive Type Regression<br />Weakly Negative Correlation, m=-0.0507<br />As drive type switches from Rear to Front MPG increases, AWD is the worse.<br />Rear wheel drive vehicles typically have more horsepower so the decrease in MPG is expected.<br />
  6. 6. Fuel Type<br />
  7. 7. Analysis of Fuel Type Regression<br />No Correlation between Fuel Type and MPG, m= 0.0136<br />Premium Fuel is more efficient, but that is almost completely offset by the higher horsepower engines in most cars requiring premium.<br />
  8. 8. Weight<br />
  9. 9. Analysis of Weight Regression<br />Strong Negative Correlation between Weight and MPG. M=-119.92<br />For every 119.92 lbs added to a vehicle it is expected to lose about 1 MPG<br />Takes more gas to pull heavier things.<br />
  10. 10. Conclusions<br />Drive Type has a moderate impact on fuel economy, front is higher than both rear and AWD.<br />Fuel Type almost no difference between gas mileage of cars using regular compared to those using premium.<br />Diesel has the best gas mileage but costs about $1 more per gallon than regular<br />
  11. 11. Conclusions Continued<br />Weight has the biggest impact on fuel economy other than horsepower. For every 120 pounds a car sheds it gains roughly 1 MPG<br />Clean out your car on a regular basis to ensure that you are getting the best gas mileage.<br />
  12. 12. Any questions?<br />
