On the Laguna Seca Raceway in California, a Tesla Model S version equipped with new ‘Plaid’ powertrain has set a new record for a four-door sedan.

According to an announcement by Tesla, the Model S with the Plaid drive was recently test driven on the race track in California, where it clocked a time of 1:36.555 to lap the raceway. The time taken by the Model S with Plaid powertrain was one second faster as compared to the earlier record for a four-door sedan.

Announcing the new record set by Model S with Plaid drive, Tesla said in a Twitter post: “We lapped Laguna Seca in 1:36.555 during advanced R&D testing of our Model S Plaid powertrain and chassis prototype.”

Tesla has not yet disclosed any details pertaining to the new Plaid drive, nor has the company revealed the modifications made to the Model S chassis. However, Tesla CEO Elon Musk has said that the automaker will “soon” publish more details about the Plaid powertrain and the chassis modifications.

Tesla has revealed that the production of the new Plaid powertrain is scheduled to commence in about one year. Tesla’s Model S, Model X, and new Roadster 2 will be outfitted with the Plaid powertrain, but not the Model 3 or the forthcoming Model Y. The cost of the Plaid powertrain, as per Tesla’s announcement, will be higher than the automaker’s current offerings, “but less than competitors.”
