Porsche Cayenne Turbo, Panamera Turbo and Turbo S recalled in Canada

Article by Christian A., on July 13, 2012

In Canada, a recall has been issued for certain 2012 Porsche Cayenne Turbo, 2011-12 Panamera Turbo and 2012 Panamera Turbo S vehicles over the discovery that the turbine in the turbocharger may have been improperly manufactured. Transport Canada announced that the defect will lead to a significantly poorer performance.

If the car continues to be used, it may result to a fracture in the turbine shaft. If this fracture occurs and the shaft is removed from its bearing, there may be oil in the exhaust system and this may result to a fire. For now, the recall covers just 24 units.

Although the National Highway Traffic Safety Administration hasn’t been involved yet, it may become an issue in the U.S. since Porsche models are imported. Nevertheless, the recall affects very few vehicles so it isn’t probable. Canadian owners of recalled vehicles can get their vehicle’s turbo assembly replaced by the dealership for free.

The totally enhanced roster of V8 power units is constructed with a stronger 4.8-liter naturally-aspirated engine, now with an output of 400 hp and 500 Nm/369 lb-ft max torque in the latest Porsche Cayenne S and a supercharged 500 hp including 700 Nm/516 lb-ft in the latest Cayenne Turbo.

Because the two strong units were improved and designed side by side, the natural-aspiration and the turbocharged engine have a lot more in common than anyone can imagine. And once more, it automatically follows that the new V8 engines showcased in the Cayenne Turbo and the Cayenne S are matched with modern innovation to cut down fuel use, like on-board network recuperation, thermal management, Auto Start Stop function and variable overrun control.

The tested light-alloy block of V8 power units is more improved by the better use of magnesium and aluminum, decreasing the weight by 7 kg or 15 lb on the valve timing cover, the camshaft adjuster, the valve cover itself, the crankdrive and various bolts.

As a sample, the new batch of V8 power units are included with the latest light camshaft adjuster for adapting valve timing via VarioCam Plus, which is built of aluminum. This does not only cut down the weight of the engine by around 1.7 kg or 3.8 lb, but it also decreases the rotating masses, providing a more agile engine response and enhancing the speed of adjustment.
