A stock Tesla Model S P85D was recently tested by Drag Times on a dynamometer and delivered 864 pounds-feet of peak torque which helps explain why it can be quicker to 50 mph than a Lamborghini Aventador.

Tesla rates the new all-wheel-drive car with pricing that starts just shy of $106,000 at 471 horsepower to the rear wheels, and the front motor drives the front wheels with 221 horsepower for 691 horsepower total.

After successive runs the car consistently was able to hit 864 pounds-feet total right off the line with its “instant torque,” but as Drag Times’ dyno chart showed, the peak was not sustained.

“It should be noted that while the torque falls of pretty quick on the dyno and it’s noticeable when driving on the street,” said Drag Times. “Tesla states that the full potential of the P85D has not been fully released yet and that future software updates will provide even more power at higher speeds.”

The excerpt from a Tesla communication explains further:

The P85D top speed is currently electronically-limited to 130 mph. In the coming months, we will be able to upgrade the car free of charge to enable a 155 mph top speed. This free update will be available for the lifetime of the car (not limited to the first owner). Additionally, an over-the-air firmware upgrade to the power electronics will improve P85D performance at high speed above what anyone outside Tesla has experienced to date. In other words, the car will be better than you experienced. This free upgrade will be rolled out in the next few months, once full validation is complete.


Drag Times has also posted street videos of the Model S P85D starting from zero and rolling on against a P85, and the results are pretty dramatic.

Expect to see actual times drag runs on a proper drag strip soon. Sunday January 18 is the date for Drag Times Street Car Drags event, which was partly why it had the P85D now.

“[W]e’ll have 12 Tesla Model S cars racing themselves and other exotic cars down the drag strip at Palm Beach International Raceway,” wrote Drag Times. “Since the Florida weather provided us with pouring rain all day and the track was closed, performance testing wasn’t quite an option, although as you’ll see later, we did some launches in the rain and the Tesla did amazing.”
