Not sure about this one.. what is the point of a Panamera minus rear leg room? Make it a two door, offer a cabriolet - then it works.

 

I love my PS4 but it is a big @$$ car. An E class competitor, if it has even just decent adult room for 2 in the back and a hump in the middle for a kid, would probably be lighter than the panamera, as it is smaller, and even easier to toss about. Given the right engine, that could really be fun and a good M5 fighter with porsche's road handling prowess. It probably would not have as much road presence as the panamera though
