Electric car manufacturer Tesla has announced in a blog post today that they have been making refinements on their Model S and Model X’s drive train and suspension enabling their high-end electric cars to travel even further on a single charge.
The «Long Range» variants of the Model S and Model X are now rated for 370 Miles / 595 Kilometer (Model S) and 325 Miles / 520 Kilometer (Model X) of range on a single batter charge under the EPA cycle standard.
New electric motors for added range and power
Tesla further states they didn’t change anything about the batteries yet, with all the benefits in range coming from Tesla’s latest generation of drive unit technology, which combines an optimized permanent magnet synchronous reluctance motor, silicon carbide power electronics, and improved lubrication, cooling, bearings, and gear designs to achieve greater than 93% efficiency.
The net effect is said to be more than 10% improvement in range, with efficiency improvements in both directions as energy flows out of the battery during acceleration and back into the battery through regenerative braking. In addition to adding range, power and torque increases significantly across all Model S and Model X variants, improving 0-60 mph times for their Long Range and Standard Range models.
New Model S and Model X charge rate
Along with the new drivetrain, Tesla says it’s also bumping up the charge rate of Model S and Model X:
“Paired with the new more efficient drivetrain design, Model S and Model X are now capable of achieving 200 kW on V3 Superchargers and 145 kW on V2 Superchargers. Together, these improvements enable our customers to recharge their miles 50% faster.”
Quick reminder: When Tesla launched Supercharger V3 in February, the company announced a 250 kW charge rate for Model 3 at the new stations. As the battery used in Model 3 is different from the one used for Model S and Model X, we’re not expecting to see the same charging rates on these cars yet. A change in battery composition for Model S and X might follow next year, though, as CEO Elon Musk stated in a recent event.
