Ok, so just what is a Grass Slide? Well, its when you slide on the grass sideways while keeping your speed up. It's a pretty cool technique.

Note that it will only work on the grass in Trackmania 2 Stadium, Trackmania Nations Forever, or in the Stadium environment in Trackmania United.

I'm sure you do donuts (burnouts) when you're waiting for the last few seconds of the race to count down. It's basically the same idea for a Grass Slide. You simply hold down your accelerator while turning the direction you want, while holding the brake. This works best if you can get some time in the air to turn your vehicle 60-90 degrees in either direction before you land. It's also possible to do it by just driving straight onto the grass, but it doesn't work as well.

I've made a short video to show you how its done.

This technique will come in handy when you're playing on some LOL servers. You will probably come across tracks that require you to take hairpin turns on the grass to get to the finish.

I hope this short guide helps, and any questions, comments, suggestions etc are appriciated :)

Enjoy sliding!
