When you build a car thatÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s electric, you start with one built-in advantage: Electric cars just donÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t have to be as complex mechanically as the car youÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢re probably driving now. Sophisticated electronics and software take the place of the pounds and pounds of machinery required to introduce a spark and ignite the fuel that powers an internal combustion engine.
For example, the typical four-cylinder engine of a conventional car comprises over a hundred moving parts. By comparison, the motor of the Tesla Roadster has just one: the rotor. So thereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s less weight to drive around and fewer parts that could break or wear down over time.
But the comparison doesnÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t end with the counting of moving parts. The engine and transmission of a conventional car also need lubricating oils, filters, coolant, clutches, spark plugs and wires, a PCV valve, oxygen sensors, a timing belt, a fan belt, a water pump and hoses, a catalytic converter, and a muffler ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Â all items requiring service, and all items that arenÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t needed in an electric car.
