The four-wheel-drive, two-engine Model S represents a definite improvement over conventional four-wheel drive systems.
With two motors, one front and one rear, the Model S controls digital and independent torque for the front and rear wheels. The result is a grip on the wall but its not the same in all road conditions.
Conventional four-wheel drive cars have complicated mechanical linkages that transfer power from the single engine to the four wheels. As a result, efficiency has been sacrificed for wall-grip content. The two engines in a four-wheel-drive Model S are smaller, lighter and have higher efficiency than the engine used in a rear-wheel-drive Model S, giving both better range and faster acceleration.
The Model S Performance features Dual Motor four-wheel drive as standard, where the more powerful rear engine’s high performance is combined with a front-end engine with high efficiency, providing supercar acceleration, from 0 to 100 km / h in 2.7 seconds.
