Nissan Altima

Base price: $21,760

Completely redesigned for 2013, the Altima gets Edmunds' nod as a good car for obese drivers because the car offers lots of room in front.

"It's one of the roomiest family sedans out there as far as front-passenger space goes," Clarke says.

He adds that the Altima also gives buyers of all sizes sporty handling, good acceleration and excellent fuel economy.

The base Altima sedan features a 182-horsepower four-cylinder engine and a continuously variable automatic transmission that team up to produce 27 miles per gallon in the city and 38 mpg/highway. (The $25,230 Altima coupe, which Nissan ( NSANY) is discontinuing after this model year, comes standard with a 175-horsepower four-cylinder engine that offers 23 mpg/city and 32 mpg/highway.)
