Dual-motor Model 3 sedans will employ an AC induction front motor (like the Model S and Model X ), and a switched reluctance, partial permanent magnet rear motor with silicon carbide inverters. "Performance drive units are lot sorted for highest sigma output & get double the burn-in," Musk said in another tweet. One of the motors is optimized for performance, while the other is for range. Additional model features will include 20-inch performance wheels, a black-and-white interior and carbon fiber spoiler. Enlarge Image Tesla CEO Elon Musk took to Twitter to talk about a new performance trim of this car, the Model 3. Tim Stevens/Roadshow What does performance cost? $78,000 including "cost of all options, wheels, paint, etc. (apart from Autopilot)," says Musk. The CEO continued, "About same as BMW M3 , but 15-percent quicker & with better handling. Will beat anything in its class on the track," he claims. ( BMW's 3.0-liter turbocharged sport sedan features 425 horsepower, a 3.9-second 0-60 mph time and starts at $66,500.) One interesting feature Musk played up on Twitter is that dual-motor Model 3 sedans will be able to drive on a single motor when needed: Tesla dual motor means there is a motor in front & a motor in rear. One is optimized for power & one for range. Car drives fine even if a motor breaks down. Helps ensure you make it to your destination & don’t get stuck on side of road in potentially unsafe conditions.
