How Rear Wheel Steering Works

What is rear wheel steering? How does four wheel steering work? Rear wheel steering operates very similarly to the front wheel steering. It can be controlled electronically or hydraulically, among other methods, and is used differently depending on speed. At high speeds, all four wheels will turn the same direction. At lower speeds, the rear wheels will turn opposite of the front wheels, allowing for greater maneuverability and faster cornering response.

How Hydrogen Cars Work - Hydrogen Fuel Cells

How do hydrogen cars work? What are hydrogen fuel cells? How do hydrogen fuel cells work? How does the Toyota Mirai work? This video looks at how hydrogen (H2) can be used to power a vehicle. An onboard storage tanke send the hydrogen to the fuel cell stack, where the electrons are separated from the hydrogen via a platinum catalyst, and the energy is then used to propel the car. The electrons return to the fuel cell where they then combine with positively charged hydrogen atoms and oxygen atoms to form H2O, and the reaction is complete. The water then flows out the exhaust pipe, with no harmful emissions.
