it should be the same Diesel but without the electric, as it should be mentioned as tech. support as a feature if they have it on......    Hwever, the weight of gas/Diesel is 150kg lighter... obviously that's a no brainer to get the petrol than diesel.....    

Audi has incorporated an additional 48 Volt circuit for the electric supercharger. I assume that Porsche, considering the weight difference to the gasoline 4S, dismissed that technology. On top of that, Audi seems to have developed that technology on their own and I doubt they will pass that feature on to other Volkswagen brands that easily...
