  • On October 9, , Tesla announced the introduction of All-Wheel Drive (AWD) versions of the Model S's.

    Model S is the safest, quickest car on the road—with industry-leading performance in all weather conditions – with Dual Motor All-Wheel Drive and ludicrous.

    Initially, only two versions were available, the 60 and the Also, the all wheel drive system in the dual-motor cars distributes available electrical horsepower to maximize torque and power in response to road grip conditions and weight transfer in the vehicle. Tesla Model S in pole position! In , Tesla began building a network of volt charging stations , called Tesla Superchargers , to facilitate long-distance travel. With a total of 25, Mitsubishi Outlander P-HEVs registered by the end of December , the plug-in hybrid is the all-time top registered plug-in electric vehicle in the Netherlands.

    Attempting to directly correlate horsepower ratings in petroleum burning vehicles to horsepower in an electric vehicle is a difficult challenge. The physics of an electric vehicle propulsion system are very different from a gasoline one.

    In an EV, electrochemical reactions in the lithium ion cells create electricity. That electricity flows through power electronics that control the voltage and current, then it flows to electromagnets in the motor that create powerful magnetic fields rotating the shaft to turn the wheels. The power required to rotate this shaft has the most correlation to traditional measures of horsepower.

    However, the chain actually begins in the electrochemical reactions that happen in the battery pack. Depending on the battery's temperature, state of charge and age, the amount of electricity extracted can vary widely. There is some confusion about our methodology for specifying "equivalent" horsepower ratings for our all-wheel drive, dual motor vehicles — the "D" versions of Model S.

    This document will hopefully answer those questions. Defining electric power in terms of horsepower is not very intuitive. Kilowatts or Megawatts are a much more useful unit. Electricity alone can't generate physical motion the way a horse or a fuel-burning engine does.

    An electric motor converts electricity into motion. Think of electric power as flowing much like fuel flows from a tank to an engine. Various situations low state of charge, cold temperatures, etc. In other cases, the potential flow of electricity may exceed the capability of the electric motor warm battery, short duration accelerations, etc. Since the battery electric horsepower rating varies it is not a precise number to use for specifying the physical capability of an EV.

    The motor shaft horsepower, when operating alone, is a more consistent rating. In fact, it is only this single or combined motor shaft horsepower rating that is legally required to be posted in the European Union. The shaft horsepower rating of the rear wheel drive single motor Model S is straightforward and roughly hp depending on the variant 60, 85 or P Also, it is generally similar, but not the same, as the battery electrical "horsepower" output.

    The difference is most obvious to drivers when the battery is at a very low SoC. In this state, the chemical reactions generate less voltage and less equivalent horsepower, even though the physical electric motor hasn't changed. The maximum torque the electric motor s are capable of is nearly unchanged as the battery horsepower changes even though the maximum shaft horsepower is reduced as the battery horsepower reduces. The torque from the two motors comes together resulting in a huge boost in acceleration, the "g's" you feel in a P85D.

    This is why Insane Mode is so delightful. The vehicle takes off slightly faster than 1g of acceleration delivering the amazing 3. This acceleration was verified by Motor Trend using a base vehicle and medium weight driver. It should be noted that a larger occupant and additional options that increase weight will reduce the acceleration.

    Also, the Motor Trend standard excludes the first 28 cm of rollout. Including this rollout adds approximately 0. One additional note is that, while gasoline cars get worse with altitude, electric cars actually get faster. All cars experience reduced air resistance, but gasoline cars become increasingly oxygen-deprived the higher they go. The Motor Trend test was done at approximately sea level, so the Model S will outperform a combustion car of the same nominal acceleration as altitude increases.
