This 'real world'' it would demolish it in, what is this?
You've got an S3 class car costing £10k less beating an RS3. It's 2 seconds faster around the Ring than the RS3 and .3 slower around Hockenheim. That's not tyres, it's the Haldex getting out of 2nd gear bends fractionally quicker.
The previous 1M was 5 seconds and 1.3 seconds faster than the RS3 respectively.
If being faster in the rain, or launching off inner city roundabouts is important to you, then yes, it'll be faster.
