2+2 (car body style)

In car classification, 2+2 is a configuration with seating for the driver and one passenger in the front plus two smaller seats for occasional passengers (or children) in the rear.

A 2+2 has just two rear seats rather than the more common three. Reasons for this may include a car's more sporty nature, typical low roof line, wide wheel arches, and (because of being front engined with rear-wheel drive or four-wheel drive) wide central transmission tunnels, the last of these being the most pressing problem for a third (middle) seat. For example, the Porsche 911 is a rear engined, rear wheel drive, so it lacks a large transmission tunnel, but loses space in the rear due to its wheel arches, reducing the space to 2 passengers.

Space in the rear is most noticeably absent in terms of longitudinal leg-room. This is again often due to the low roof line, and other elements of body styling, in addition to large engine compartments and sometimes also large areas given over to the convertible roof in the case of a 2+2 convertible.

Many vehicles may fall into the definition, and there is no official body offering a strict definition, but cars called 2+2s must have:

and also strongly tend to have:

Many convertible, targa top and hatchback cars are strictly within this definition, but are rarely deemed 2+2s. Few cars have ever been specifically marketed as 2+2s—most often this is to distinguish them from a 2-seat open version of the same model. Prominent are the classic Jaguar E-type fixed-head coupé 2+2, the Lotus Elan 2+2, the Nissan 300ZX 2+2, the Chevrolet Monza 2+2, the 1965-66 Mustang 2+2 and the Pontiac 2+2 models, including the aerodynamic Grand Prix of NASCAR fame.
