I was given an RS5 to sample a while ago in preparation for the launch of Wide Open Throttle. I've owned a number of Audis in the past, a 2012 A6 3.0T currently. My brother has an R8 V10 that I have the spare key to, as well, hah. Unfortunately, he lives about 20 miles from me, so access to the car isn't immediate.

Anyway, see below:

I definitely got a huge kick out of the car. I prefer to an E92 M3, to be honest and that's not bias speaking: I used to have an E92 335i Coupe and drive my brother's M6 quite often - I love both. I explain my preference over the BMW in the review.

Speaking of M6, he's taking delivery of his 2013 in February. We'll be piecing a review of that as soon as we pick it up.
