Cruising Sydney's best tunnels in the Audi R8 RWS

A 5.0-litre V10. A stonking 397kW. The sprint from 0-100km/h in 3.7 seconds. And it’s 50kg lighter than its quattro AWD big brother making it more nimble and agile. This is the rear wheel drive Audi R8 RWS. Unfortunately there are a distinct lack of Alps and snow capped peaks in the suburbs surrounding Sydney but there is something that the harbour city is certainly not lacking in. Tunnels.
