Encase it in a torpedo shaped shell. Replace windscreens with videocameras and monitor iside instead.
Driving lighter weight vehicles.
At http://www.garrysmod.orgYou can download numerous drivable vehicles, I suggest getting a mod called "Vmod" which contains many vehicles to drive. IT can be found on the website or by Googling it.

Volkswagon has been a constant and solid provider for diesel vehicles for decades. But for a comprehensive comparison of diesel vehicles check out Edmunds (www.edmunds.com).
I would suggest temperature and pressure.

The last time I figured this out, I found out that bicycle with no training wheels are faster. The comparison of generating speed is this; bicycles allow you just to pedal to generate fast speed, although freestyle scooters allow to step on the ground and push forward. I suggest you use a bicycle if you are entering a racing competition.
