Tesla Boosts EV Range, Revives Cheaper Models

Tesla Inc. is reinstating lower-priced “standard range” versions of its Model S sedan and Model X crossover vehicles.

The least-expensive Model S and Model X now start at $78,000 and $83,000, respectively. Each is $10,000 less than the long-range iterations, which can travel 75-85 more miles between recharging.

Tesla also has redesigned the drivetrain used by the two models to make them about 10% more efficient. The changes hike the U.S.-rated range of high-end Model S and X vehicles, which come with two motors and big 100-kWh batteries, to 370 miles and 325 miles, respectively.

The efficiency refinements, which apply to all versions of the S and X models, involve the drive motor, vehicle lubrication, wheel bearings, cooling and gear designs. The updates also shorten acceleration times for all versions of the two models, according to the company.

The two model lines also are now been equipped to handle direct-current charging levels as great as 200 kW. The company says the update can cut charging time by as much as 50%.

Finally, S and X models are gaining an adaptive version of the company’s air suspension system. The updated design adjusts the vehicle’s ride and handling according to speed, road conditions and driving style.
