As you may know already Porsche finally introduced the Cayenne Diesel in the United States but it appears that the European customers will be one step ahead of us. Why? Because Porsche will introduce the Cayenne S Diesel in Europe and this model will be powered by a V8 engine, instead of the standard 3.0 TDI V6 engine found on most of the Audi models.
Currently, Audi vehicles are powered by a 4.2-liter V8 diesel engine delivering makes 346 hp and 590 lb-ft of torque, but the Cayenne S Diesel will get a refreshed V8 diesel engine. For those who don’t know, the V6 diesel engine found on the Cayenne Diesel delivers 240 hp and 406 lb-ft of torque.
The bad news is that the new Cayenne S Diesel powered by the new V8 will not be available in the United States (at least for the moment) because building it to comply with U.S. emissions and crash standards would cost Porsche millions of dollars.
Still, the financial part is not the big problem because Porsche sales are seeing a record… the problem is that the diesel-powered cars are not quite popular in the United States. [source: Caranddriver]
