The high-performance Vue Red Line was joined in 2007 by the Green Line model. The Green Line was a [[mild hybrid]], or "assist hybrid", using GM's [[belt alternator starter]] (BAS) system.<ref>{{cite web|url= http://www.gm.com/company/gmability/adv_tech/300_hybrids/bas_050103.html |date=November 11, 2003 |accessdate=June 14, 2007 |title=GMability Advanced Technology: GM's Belt Alternator Starter |url-status=dead |archiveurl= https://web.archive.org/web/20061029110339/http://www.gm.com/company/gmability/adv_tech/300_hybrids/bas_050103.html |archivedate=October 29, 2006 }}</ref> An electric motor connected to the crankshaft via a special accessory drive belt and the Green Line included a modified automatic transmission.

The [[start-stop system]] automatically stops the engine when the vehicle halts and instantly restarts it when the brake pedal is released. The electric motor assists somewhat during initial launch, providing torque smoothing, and during heavy acceleration. A 36-volt [[nickel metal hydride battery|nickel metal hydride]] (NiMH) battery pack, located under the load floor, powers the BAS and also stores electricity from [[regenerative braking]]. The regenerative brake charging and electric motor assist functions are shown to the driver via an analog gauge on the dashboard, and real-time fuel-economy feedback is accomplished via an "eco" light that glows when the instantaneous fuel economy exceeds the published window sticker fuel economy rating.

The fuel savings are 20% up from the base vehicle's {{convert|22|mpgus|L/100 km|abbr=on}}/{{convert|27|mpgus|L/100 km|abbr=on}} city/highway EPA sticker to {{convert|27|mpgus|L/100 km|abbr=on}}/{{convert|32|mpgus|L/100 km|abbr=on}}, the highest highway fuel economy of any 2007 model SUV sold in the U.S. market.<ref>2007 model EPA Highway rating of 32 mpg{{better source needed|date=May 2024}}</ref> In Canada, according to Saturn, the Vue achieved an estimated {{convert|8.8|L/100 km|abbr=on}} city and {{convert|6.7|L/100 km|abbr=on}} highway.<ref>"Saturn Vue".

The Green Line has a {{convert|170|hp|kW|0|abbr=on|adj=on}} 2.4&nbsp;L [[GM Ecotec engine|Ecotec]] [[DOHC]]-phaser engine which replaced the standard {{convert|144|hp|kW|0|adj=on}} 2.2&nbsp;L I4 engine. The {{convert|0|-|60|mph|km/h|abbr=on}} acceleration time was improved by 1.0&nbsp;second. Pricing for the hybrid was about {{US$|2000}} more than a similarly equipped Vue, and debuted in production form on January 8, 2006, at the [[North American International Auto Show]] in [[Detroit]]. The Green Line went on sale in the third quarter of 2006.
