Instead of using a 3.6 liter naturally aspirated V6 engine, the Porsche Cayenne that's meant for the Chinese market will use a supercharged 3.0 liter V6 powerplant from the Audi S4. This means that finally, the analysts's prediction of China-destined cars to be better vehicles than those meant for the other parts of the world have come true.
Porsche is making this move because of a tax legislation that's related to the engine capacity of the car. If the 3.6-liter engine is used, this would put the SUV in the 3 to 4 liters category, making it get to a 40% tax level. But with the 3.0-liter engine from the S4, the Cayenne would fall under the 3 liter limit, reducing the taxes to 25%.
What this ultimately means is that the Chinese customers will receive a more advanced machine but with a higher tax reduction. They get a car that offers enhanced driveability as well as more horsepower and torque.
The supercharged 3.0 liter TFSI V6 unit delivers 333 hp between 5,500 and 7,000 rpm and a maximum torque of 324.5 lb-ft between 2,900 and 5,300 rpm. Meanwhile, the naturally aspirated 3.6 liter engine in the Cayenne has an output of 300 hp at 6,300 rpm and 295 lb-ft at 3,000 rpm.
Powering the Audi S4 Sedan and Avant is the 3.0 TFSI engine that develops max output of 245 kW (333 hp) and max torque of 440 Nm (324.53 lb-ft).
With this engine at its core, the S4 Sedan consumes an average of 8.0 liters of fuel per 100 km (29.40 US mpg) without compromising performance. In fact, the 3.0 TFSI engine allows the Audi S4 to sprint from zero to 100 km/h in just 5.0 seconds and reach an electronically limited top speed of 250 km/h.
