LOS ANGELES - Drivers of Tesla Motors' new range-topping version of the Model S sedan, the all-wheel-drive P85D, will get to choose from three drive settings: normal, sport and insane. Choose "insane," and the all-electric P85D will vault from 0 to 60 mph in 3.2 seconds, Tesla says, quicker than a Porsche Panamera Turbo S or an Audi RS7.
