INTRODUCTIONINTRODUCTION

Cars are immensely complicated Cars are immensely complicated machines, but they do an incredibly simple machines, but they do an incredibly simple job.job.

Most of the complex stuff in a car is Most of the complex stuff in a car is decided to turning wheel decided to turning wheel

The two basic elements that largely dictate The two basic elements that largely dictate car design today are car design today are

1. The internal combustion engine1. The internal combustion engine 2. Mechanical and hydraulic linkages 2. Mechanical and hydraulic linkages

HY-WIRE BASICSHY-WIRE BASICS

The defining characteristic of the Hy-wire The defining characteristic of the Hy-wire is that it doesn’t have either of those two is that it doesn’t have either of those two things: engine and mechanical and things: engine and mechanical and hydraulic linkageshydraulic linkages

Instead of an engine, it has a fuel cell Instead of an engine, it has a fuel cell stack stack

Instead of mechanical and hydraulic Instead of mechanical and hydraulic linkages, it has a drive by wire system linkages, it has a drive by wire system
