In America, compact sport utility vehicles and sedans have average lengths of 177.2 inches and 172.3 inches, respectively. Large cars are longer by an additional 15 to 20 inches, while medium sedans and SUVs are 10 to 20 inches longer than their small counterparts.
Not only have modern cars grown in length, but also in width and weight. A 2007 survey by Edmunds.com found that, on average, compact sedan automobiles are now 2 inches longer, 2 inches wider, and 374 pounds more than they were in 1997. For medium and big cars, the pattern was the same.
