In a drag race pitting a Tesla Model S P85D with the Dual Motor Drive versus the former top-dog P85+, you’ll see what a difference an extra motor can make. Without spoiling too much, let’s just say that if you like speed and torque, it’s totally worth the cost of the Dual Motor upgrade.

Officially speaking, the outgoing P85+ was rated at 416 horsepower, a healthy increase over the 302 horsepower of the base 60 kWh version and enough to propel it from 0 to 60 MPH in 4.2 seconds. That’s fast by nearly anyone’s standards, but Elon Musk wanted more, and so he approved the 691 horsepower Dual Motor all-wheel drive system. The P85D matches the acceleration of the McLaren F1 with its 3.2 second sprint from 0 to 60 MPH, adding a 220 horsepower motor to the front wheels and a new 471 horsepower motor at the rear.

That grants it a total output is 691 horsepower and 689 lb-ft of torque officially, though the dyno shows it making a whole lot more. Regardless of the actual power numbers, the P85D packs enough punch to absolutely dust a Ferrari in a heads-up drag race, but how does it do against its predecessor, the P85+?

Honestly, it’s just not even close. The P85D grabs the road and just goes in a way that makes the P85+ look like an absolutely dog. And keep in mind, the P85+ is quicker and more powerful than 90% of the cars on the road, but the P85D walks away like its just another Toyota Camry. It also grants owners in Norway access to congestion-free bus lanes, an enormous perk no other supercar can apply for.

At $120,000 it ain’t cheap, but I know people who have poured twice as much money into cars that aren’t nearly as fast. Meet the new class of American muscle cars.
