Customers can purchase the additional Track Package if they want their Tesla Model S Plaid to accelerate.
Owners of German Tesla Model S Plaid, however, also receive an additional bonus.
The Track Pack unlocks a top speed of 200 miles per hour (322 km per hour).
Steven Peeters, the first customer in Europe to get the Track Package installed on his Tesla Model S Plaid, was travelling across Germany.
He was interested in finding out if the Tesla's stated top speed of 200 mph was true.
After the exertion, the Model S Plaid's speedometer registered 328 kilometres per hour.
The automobile seemed to have some power left over at that speed because it was still accelerating strongly at the top of the range.
Steven said that it could go even faster.
