'''Theta''' is [[General Motors]]' [[automobile platform]] for [[Compact crossover SUV|compact]]/[[mid-size crossover SUV]]s. The architecture debuted in 2002 with the [[Saturn Vue]] and was later used for the [[Chevrolet Equinox]] and [[Daewoo Winstorm|Captiva]] and similar models.

==Development==
The Theta uses a four-wheel [[independent suspension]]. Engine choices include the [[Family II engine|Family II]] [[straight-4]], [[GM Ecotec engine|Ecotec]] [[straight-4]], ''[[GM 60-Degree V6 engine#3400|3400]]'' [[V6]], and even a [[Honda]] V6, the [[GM L66 engine|L66]]. A 5-speed [[automatic transmission|automatic]] and two 5-speed [[manual transmission]]s are used.

The original [[Saturn Vue]] used a short 106.6&nbsp;in (2708&nbsp;mm) wheelbase, with a 61&nbsp;in (1549&nbsp;mm) track. The [[Chevrolet Equinox]] and [[Pontiac Torrent]] use a stretched 112.5&nbsp;in (2857&nbsp;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|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 vehicle|hybrid]] powertrain, GM's [[belt alternator starter]] (BAS) system, in 2006.

General Motors has created a premium version of Theta for [[Luxury vehicle|luxury]] applications. It mixed elements of the current Theta and the new [[GM Epsilon platform|Epsilon 2]] architecture.<ref>{{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}}</ref> Thus this platform is sometimes also referred to as '''Theta-Epsilon''' (GMT166).<ref>{{cite web|last=Lassa|first=Todd|title=Caddyshock!
