One of the most amazing things about the Tesla Model S P85D—aside from the face-melting acceleration of its dual motors and 864 lb.-ft. of rear-wheel, zero-RPM torque—is the car's ability to receive over-the-air software updates. Whenever Tesla's engineers find an improvement, they send a magical brainwave through the ether to your car, the same way your smartphone gets updated. No trip to the dealer required.Tesla founder and formerly gawky McLaren F1 owner Elon Musk took to Twitter today to reveal that the latest update: an algorithm tweak that makes the silent screamer P85D even faster. Tesla P85D 0 to 60mph acceleration will improve by ~0.1 sec soon via over-the-air software update to inverter algorithm — Elon Musk (@elonmusk) January 29, 2015 P85 acceleration will also improve, but not quite as much — Elon Musk (@elonmusk) January 29, 2015 But lest we think that the dual motors in the P85D are just there for scaring the daylights out of unsuspecting passengers, Musk tweeted to inform us that there's a pragmatic reason for the design: Tesla dual motor cars are also all-wheel drive. Main goal of dual motor was actually insane traction on snow. Insane speed was a side effect — Elon Musk (@elonmusk) January 29, 2015 Either way, it's pretty insane. And it makes the sizzlingly quick P85D a capable winter car: Video made by owner of a P85D going up a 14% grade on snow passing a whole bunch of stuck SUVs https://t.co/LC9AHx0fuC — Elon Musk (@elonmusk) January 29, 2015 So to recap: If you own an all-electric, seven-passenger, all-wheel-drive performance sedan that accelerates as quickly as a McLaren F1, in the coming days it will magically become even faster without you having to do a damned thing. We live in the future and it is amazing.
