學了一下, 柴油卡宴沒有在受影響之列.

受影響的是TDI 2liter V4 engine. 估計V6的都沒事.

"But the highly profitable sports car and SUV manufacturer has emerged unscathed, a company source told Business Insider. 

"Porsche conducts our own emissions testing and calibration," the spokesperson said. "We are not affected by VW's problem." 

In the US, the only Porsche powered by a VW Group TDI engine is the Cayenne Diesel SUV. And it's a 3.0-liter V6, while the engines affected by the scandal are 2.0-liter 4-cylinder powerplants.

The diesel Cayenne is powered by a larger 3.0 liter V6 unit that incorporates urea scrubbing technology that cleans the SUV's exhaust."
