The DMAX V6 engine initially developed an output of 177 hp at 4,400  rpm , with torque of 350 Nm at 1,800  rpm . Subsequently, from 2006, this engine was slightly revised, developing 180 hp of maximum power at 4,000  rpm and 400 Nm of torque at 1,800  rpm with  turbocharger and intercooler . This engine was fitted to models of different brands, but somehow linked together. These models are:

• Renault Vel Satis
• Renault Espace IV
• Saab 9-5
• Opel Vauxhall Vectra
• Opel Vauxhall Signum
