This month Tesla Motors announced the Dual Motor Model S, the first consumer-ready dual electric motor car. The car gains in efficiency – at least 10 miles on a single charge – thanks to smart current allocation between the motors. It also gains the traction benefits you’d expect from all-wheel drive.

If you live where slippery conditions require all-wheel drive, an electric car may finally be an option now.

Tesla also announced hardware for every new Model S that includes ultrasonic sensors, a forward camera, and electronic braking. The software will start modestly, enabling Model S’s to make lane changes and maintain traffic-aware cruising speeds. Tesla plans to eventually upgrade the software to the point that your car rolls up to your door in the morning.
