The rear differential lock on the 997.1 Turbo "supports the driving dynamics of the controlled all-wheel system Porsche Traction Management (PTM), and offers the following advantages: higher traction on changing road surfaces and when cornering in the limit range; improved driving stability in the event of load changes when cornering in the limit range; [and] improved agility in corners in the event of high lateral acceleration in the limit range" [Service Information, 2007 Technik Introduction: 911 Turbo, 3.2].
