Is a tornado faster than a car?

In terms of wind speed, Yes.

A tornado is usually rotating at about over 70 mph, but wind speeds can exceed 300 mph, though tornadoes this strong are extremely rare. But even then 20% of tornadoes have winds in excess of 110 mph.

In terms of forwards speed generally not. The average tornado travels at 35 mph, the fastest recorded traveled at 73mph. However, these speeds are still fast and the path of a tornado is difficult or impossible to predict, making it unwise to attempt to outrun a tornado.
