Perfect Runs reward players for smooth driving in the Asphalt series. You can perform a Perfect Run by not touching walls, wrecking, or being knocked down for 20 seconds. Knocking down other racers, traffic, or obliterating obstacles will not affect your Perfect Run. After twenty seconds, you will be rewarded with a small nitro bonus (25% of your nitro bar). Touching the sides of ramps and falling out of the map also will not affect your Perfect Run.
One can sometimes exploit the nitro bonus gained in Perfect Runs by precisely timing a deliberate bump into a wall so that the perfect run is reset, and after 20 seconds (assuming the player goes flawless after that) the nitro boost is awarded along with the Perfect Run. This technique is mostly used to gain nitro in long stretches with little nitro such as Tokyo tunnel part.
Though not initially obvious, Perfect Runs are not awarded if one simply drives slowly but perfectly.
- In Asphalt 8's Career mode, there are more than 40 races that have Perfect Run bonus stars to be recieved, making it one of the most common type of bonus stars.
