Fast Brassless Survival Car/Chassis

As the name suggests, this is a semi-fast brassless "car" (really just a chassis) that goes at ~7.3 m/s and ~14.5 m/s when the chain gearshift is active. It uses three engines, Four LARGE wheels, Can go up a block and a half, And has rope connectors on the sides so you can get it right side up if it manages to flip upside down. Finally there is a picture of the redstone link frequency but you can change that to your liking.
