Tesla reduced U.S. starting prices by $10,000 on its flagship models, the Model S sedan and Model X crossover, by introducing new versions with less battery range and slower acceleration, according to the company's website.
The surprise move is the latest tactic by Tesla CEO Elon Musk to stimulate demand for the automaker's aging lineup amid slower growth for battery-electric vehicles this year in the U.S., analysts say.
According to data from Experian, Model S registrations fell 55 percent in the January-June period — compared with the first half of last year — to 6,964. Model X registrations fell 5.8 percent to 12,341 for the same period, Experian said.
The new trims are dubbed "standard range" by Tesla.
