While horsepower and torque have not yet been revealed, Musk says the new standard dual-motor all-wheel-drive Model 3 will hit 60 mph in 4.5 seconds and run to 140 mph. The second motor, which brings with it AWD, will cost an extra $5,000. 

The dual-motor all-electric compact sedan will have a total driving range of 310 miles, the same as the current long-range, big-battery Model 3 equipped with a single motor. According to Tesla, today's mono-motor, rear-wheel-drive model hits 60 mph in as little as 5.1 seconds.
