It’s now official: Tesla’s “D” does, in fact, stand for dual-motor, which is the Silicon Valley-based manufacturer’s idea of all-wheel drive. It not only features all the advantages of having instant torque vectoring capabilities and the inherent grip/handling benefits, but it also promises “insane” performance too.

CEO Elon Musk said that the car will have three drive modes the last of which is called just that: “insane.” Acceleration to sixty for the top-spec 691 hp P85D model is 3.2 seconds, and the top speed has also been raised to the German gentlemen’s standard of 155 mph / 250 km/h; the 85D also gets the higher top speed, while the 60D gets 5 mph / 8 km/h extra over the RWD variant.

However, all-wheel drive won’t only be available on the 85 kWh battery pack cars; a 60 kWh version is the entry level option, and it starts at $75,070 – $4,000 more than the equivalent rear-wheel drive only variant. Next up is the $85,070 non-performance 85 kWh car which is also $4,000 more expensive than the regular two-wheel drive version.

Sitting at the top of the range is the P85D which is $14,600 more expensive than the normal P85, though it offers the most significant performance boost.

As for range, both the 85D is rated at 275 miles / 440 km, which is 10 miles / 16 km more than the 85. The 60 kWh model gets an even bigger boost, as its range goes up from 208 to 225 miles / 360 km. However, the P85D does 10 miles less on a single charge than the equivalent P85.

Along with the new twin-motor setup, Tesla is also debuting an autopilot feature. It’s a semi-autonomous system that uses new hardware and relies on cameras and radar to read its surroundings. A quick demonstration of how it works is shown in the second and third videos posted below, both of which also feature an acceleration run.
