Tesla Roadster is a fully electric sports car, and is the first car to be produced by electric car firm Tesla Motors. Tesla claims prototypes have been able to accelerate from 0-60 mph (100 km/h) in under 4 seconds, and reach a top speed of over 130 mph (210 km/h).
With Power Electronics Module (PEM), Most of the subsystems in the Tesla Roadster are completely electronic and under direct software control. But unlike all other cars, these systems are not a hodge-podge of independent systems — instead, they are designed as an integrated system, the way complex network and computer systems are designed today.
