Brief description: General

The turbo on the Saab 9-5 belongs to a new turbo family, the Garrett 17 (GT 17).

The V6t Ecopower is the first car engine in the world with asymmetric turbocharging which means that the turbo is driven by the exhaust gases from only three cylinders (2---4---6). However, the turbo supercharges all the cylinders. The asymmetric turbocharging was designed to combine the supercharged engine's superior torque, low fuel consumption, and environmental advantages, with the softer running and dampened noise of the V6 engine.

The asymmetric turbocharging means that the engine develops its maximum torque of 310 Nm already at 2100 rpm. This means that the engine runs very quietly and it is more comfortable to drive the car because high engine speeds are not needed to achieve the best performance.
