just read the article today in the Sport Auto.
tester/author was Anja Wassertheurer. She is a very fast driver - participating also at the 24h at Nürburgring.
I was totally shocked/surprised by this article.
I expected the RS5 to take a slight win over M3. But it was completely the other way round.
There was not ONE point where the RS5 could shine.
RS5: Heavy as hell, very bad steering
High speed driving comfort on the Autobahn was way better in the M3 with the EDC
Fuel consumption lower with M3
DCT/Motor characteristic of M3 better
Handling (slalom) M3 much faster
Hockenheim race track: M3 1,1s faster
Frankly speaking and reading a bit between the lines: It was a slating review by the sport auto magazine. And just for your info. Sport Auto is the benchmark of all german car magazines for sport car enthusiasts.
