Good stuff. What he didnt mention was the S Q4 is a couple tenths faster 0-60 than the S (!) which I find fascinating; afaik that's unheard of wrt awd German cars. It also supports Maserati's claim that the Q4 delivers 100% power to the rear in "normal" conditions.
The difference being not only the way the AWD system works as opposed to the Germans but also the weight addition with the AWD system is only 100 some odd pounds compared to the Germans.
