A pre-production prototype believed to be the upcoming Porsche Cayenne Coupe has been spied again, this time during cold weather testing in Europe.
It's believed engine and transmission options will largely mirror those offered in the next-generation Porsche Cayenne which has also been spied testing in recent months, including a range of turbocharged six- and eight-cylinder petrol and diesel engines.
According to spy photographers, this test vehicle didn't make any normal engine noise, leading us to believe there could also be a plug-in hybrid variant (like the current Cayenne S E-Hybrid) and/or even a fully-electric model in the works - further highlighted by the electric warning stickers scattered around the mule's body.
Timing for the Cayenne Coupe is still unknown, but considering the wagon is expected to make its debut sometime this year, it's likely the coupe version won't be revealed until 2018, with first deliveries arriving later that year or even early-2019.
