Theta is General Motors' compact and mid-size crossover SUV automobile platform. The architecture debuted in 2002 with the Saturn Vue and was later used for the Chevrolet Equinox and Captiva and similar models.
The Theta uses a four wheel independent suspension. Engine choices include the Ecotec Family II 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 shares 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. The Grand Vitara front and rear suspensions are substantially different from the Theta vehicles. The 2007 Suzuki XL7 is based on the Theta platform and is built alongside the Equinox and Torrent at CAMI Automotive in Ingersoll, Ontario, Canada. It is the first non-GM branded vehicle to come off the Theta platform. Styled by Suzuki, the engineering was performed by GM engineers in the US and Canada.
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 as well.

Current Theta vehicles:
General Motors has created a premium version of Theta for luxury applications. Reports differ, but the consensus is that it is a combination of the current Theta and elements of the new Epsilon 2 architecture, with some Lambda components as well. Thus this platform is sometimes also referred to as Theta-Epsilon (TE). Theta Premium supports larger models than the standard platform.
