Version 0.86 introduced a new optional feature, drafting, also known as slipstreaming. When it is on, vehicles gain more speed when driving behind others, making overtaking easier. This adds a whole new dimension to racing, especially on otherwise simple tracks like oval speedways. As is customary in Turbo Sliders Unlimited, there are lots of related settings for the host to tune.
To ensure fair play, lap times achieved with the help of drafting are not eligible for leaderboards.
