CNET News - Tesla's new AWD Model D features dual motors

2014-10-10
let's release the tight okay we here we have the the chassis and that the drivetrain of the dual motor model s I've still got that the front drive unit the rear drive unit and the thing that makes this unique and special and sort of better than or wheel drive in the past is because you can dynamically shift the power from front to rear at the millisecond level so you can very quickly adjust torque more than is is possible really with the mechanically linked system so all all wheel drive systems out there are just mechanically linked with with the shaft so it's like the cooler being sort of analog whereas this is this is a digital system with all-wheel drive systems out there the that you get less mileage it's less efficient to have to have an all-wheel drive system but in the case of the model is because we're able to have two drive units where we can shift the power from from front to rear and and constantly be at the optimal efficiency point for for each motor we're actually able to overcome the penalty of the increased mass of the motor but this is this literally everything improves about the car with dual motor this there's no there's no sort of technical drawback in this case but this this car is is nuts it's like it's like taking off from a carrier deck it's just bananas it's like having your own personal roller coaster they just use it anytime so that I mean it's really mind-blowing fact that the target that we had for performance was to try to meet one of the greatest at the port the acceleration were the greatest super cause of all time which is the McLaren f1 and so we were able to actually achieve a 3.2 seconds 0 to 60 yeah it's mad okay in fact just just you know what we're going to have an option to be in the option selection you'll be able to choose three settings which is normal sport and insane it will actually say insane it's true
