Theta is General Motors' automobile platform for compact/mid-size crossover SUVs. The architecture debuted in 2002 with the Saturn Vue and was later used for the Chevrolet Equinox and Captiva and similar models.

Development

The Theta uses a four-wheel independent suspension. Engine choices include the Family II straight-4, Ecotec straight-4, 3400 V6, and even a Honda V6, the L66. A 5-speed automatic and two 5-speed manual transmissions are used.

The original Saturn Vue used a short 106.6 in (2708 mm) wheelbase, with a 61 in (1549 mm) track. The Chevrolet Equinox and Pontiac Torrent use a stretched 112.5 in (2857 mm) wheelbase, but share much with the Saturn.

The Suzuki Grand Vitara, although similar in size and appearance to a Saturn Vue, was developed by Suzuki using some Theta components, but should not be considered a Theta derivative.

Engineering for the Opel Antara and Chevrolet Captiva was performed in large part in Korea by GM Daewoo Auto & Technology, and by Opel in Germany.

Hybrids

The Saturn Vue was one of the first of General Motors' vehicles to be offered with a hybrid powertrain, GM's belt alternator starter (BAS) system, in 2006.

General Motors has created a premium version of Theta for luxury applications. It mixed elements of the current Theta and the new Epsilon 2 architecture.{{cite web|last=Davis|first=Matt|title=Saab 9-4X|url=http://www.autoexpress.co.uk/carreviews/firstdrives/267388/saab_94x.html|work=Auto Express|access-date=20 February 2012|date=April 2011}} Thus this platform is sometimes also referred to as Theta-Epsilon (GMT166).{{cite web|last=Lassa|first=Todd|title=Caddyshock!
