  • Tesla has delivered the ultimate fan car – a revamped version of its original Roadster, with crazy fast acceleration of 0 to 60 mph in just

    The Tesla Roadster Is Not the "Fastest Car in the World" The problem is, the Tesla Model S PD isn't particularly fast. Like all other.

    Tesla is a well-known manufacturer of electric vehicles. The company's founder is not Ilon Mask, as many believe. Mask is one of Tesla's main sponsors and her public face. The company has an interesting principle of work - they do not hide their designs and patents. All of them are available for use and application.

    As noted, the specs for the Model S indicate top speed is software limited, but sometime, somebody, is going to want to find out how fast this.

    Saleen will probably be providing answers to Model S top speed and acceleration possibilities. With that said, the manufacturers could have easily just spec'd out high performance tires. George with SacEV 22 October I am nearly sure the Model S is software limited, not rpm limited. That's in part why battery-powered electric cars had a reputation for being less peppy than an equivalent gasoline car, Duoba said.

    This article was updated on Aug. Blink and you'll miss it: The head-snapping acceleration of the new supercharged Model S raises a question: Just how did engineers at Tesla get the electric, seven-seat family sedan to go so fast?

    Neither was built for the masses and neither is currently being produced. The fastest custom-built race car, the Grimsel , can reach the same speed as the Tesla in about 1. Tesla confirms that the secret sauce behind this record-breaking time is the new battery. In general, a battery's energy density predicts how much energy it can release meaning how far the car drives before recharging, while the power density the energy density delivered per second determines how fast energy can go in and out of the battery.

    That, in turn, governs how fast a car can accelerate, said Jordi Cabana, a chemist at the University of Illinois at Chicago, who studies battery chemistry.

    The new Tesla battery helps quickly achieve these lightning-fast speeds by increasing the latter, Cabana said. Though exact details haven't been released, the Model S likely uses a lithium-ion battery where one layer, called the cathode, is made of a blend of nickel, manganese and cobalt oxide NMC , Cabana said.

    When charged, lithium ions from the cathode are driven through an electrolyte solution into the anode, which is made of stacks of graphite. Lithium-ion batteries that overheat can sometimes produce a runaway chain reaction and catch fire ; to prevent that, manufacturers encase individual cells containing both a cathode and anode in protective shells.

    The Tesla Model S battery likely has thousands of these cells, Cabana said. Tesla's home battery uses similar technology. The new battery may have crammed more cells into the same space of the older Tesla S battery pack, Cabana said. Historically, batteries that could produce enough power for fast acceleration or enough energy for long-range driving were typically quite expensive. That's in part why battery-powered electric cars had a reputation for being less peppy than an equivalent gasoline car, Duoba said.

    However, a study in the journal Nature found that the cost of electric batteries has been plummeting, paving the way for cheaper, speedier, longer-range vehicles. For one, engines have myriad tiny parts that must spin, push, open and close to produce internal combustion at the right times, Duoba said.

    It has to take air in and squeeze it," Duoba told Live Science. All those little effects add up. In contrast, gasoline-powered cars cannot achieve peak torque at either a very low or very high rpm. Engines are optimized to run best with certain combinations of air flow, temperature and rotational speed.

    That means the torque in gas-powered engines peaks around 4, rpm, and that a graph of torque versus rpm looks like a domed hat, Chambon said. The dome-shaped torque graph also has another implication: At low speeds, the torque needed to propel the car doesn't match the torque produced by the engine. As a result, manufacturers place a gearbox between the engine and the wheels, which matches engine speed to that needed to rotate the wheels at a certain torque, Chambon said.
