A GT, or grand touring car is a luxury automobile that's well suited to driving long distances. The most common type of GT car is a two door coupe, with either two seats or a 2+2 setup. The term comes from the Italian "gran turismo", which is itself an homage to the grand touring tradition. GT cars differ from the average two-seater sports car because they are heavier and larger, and they place more emphasis on comfort.

Most GTs have been front-engine, rear wheel drive cars, which allows for more cabin room than the rear-engine arrangement. Increased storage space, softer suspension and luxury touches add to their appeal. GT cars such as the Ferrari GTB, the Aston Martin DB9, and Mercedes' SLR McLaren cater to drivers seeking both performance and comfort, while rivaling the speed and power of more outright sports cars.

In certain professional motorsports classes, such as the FIA Grand Touring category, the GT car is strictly defined as either an open or closed car that has one door on each side and at least two seats. All GT cars must be street legal and adapted for racing. GT cars are divided into classes from the most to the least powerful: classes are GT1 and GT2.
