Tesla reveals 691-hp AWD Model S with autopilot, its most powerful model yet

As predicted, Tesla unveiled a new version of the Model S sedan tonight, featuring an additional motor up front to make it a 691-horsepower all-wheel-drive rocket — and one of the fastest sedans on the planet.

Tesla says the new Model S P85D can hit 60 mph in 3.2 seconds — just slightly slower than the 2015 Dodge Charger Hellcat — and has a range of 275 miles on a full charge, 10 more than before, thanks to being able to recapture more energy from the front wheels.

"This car is nuts," said Tesla co-founder and CEO Elon Musk, addressing a massive throng of Tesla owners at Hawthorne Municipal Aiport in Los Angeles, Calif. "It's like having your own roller coaster."
