Tesla announced Wednesday that its Model S "Plaid" development car lapped WeatherTech Raceway Laguna Seca near Monterey, California, in 1 minute, 36.55 seconds this week.

That set a track record for four-door sedans—a claim from Tesla—and it proved that its flagship model can complete a hot lap at the famous circuit.  

This is more than simply a performance milestone for Tesla, which received a healthy dose of criticism regarding the ability of its high-performance Model S sedan to deliver sustained performance on a race track in the fallout surrounding Porsche's high-profile effort to set the fastest lap time for a four-door electric sedan at Germany's Nürburgring.

It also confirms that development of a high-performance Model S is well underway. Dubbed "Plaid," in yet another reference to "Spaceballs," which which also inspired Tesla's "Ludicrous Mode" acceleration program, the new model seems poised to defend the nameplate's status as a world-class super sedan.

Musk confirmed Wednesday in a tweet that the new "Plaid" powertrain will be a three-motor system.

It will be an option for the Model S, Model X and Roadster, but not the smaller Model 3 or Y, and Musk promised that each will be less expensive than its respective competitors (we would assume he means the Porsche Taycan) with production starting in mid-to-late 2020.

Tesla's new development vehicle was also spotted running the Nürburgring, making good on Tesla CEO Elon Musk's promise that the Model S would make an appearance there this week.
