As our impressions show, the RS5 will get the full Quattro treatment. The glorious high-revving 4.2-litre V8 that powers the RS4 gets plumbed into the RS5’s nose, complete with two small and highly responsive turbochargers that will take peak power up to the 450bhp. That’s not a great deal more than the S5’s 354bhp, but the RS5 searing pace will come from its phenomenal blower-enhanced torque – expect at least 500lb ft of twist action to plateau across the rev range.
