More stable cost inflation was also a factor in reducing prices, said a spokesperson for Tesla Germany, confirming price cuts in its top European market.
The US price cuts, announced late Thursday on its global top-sellers the Model 3 sedan and Model Y crossover SUV, were between 6% and 20%, Reuters calculations showed.
For a US buyer of the long-range Model Y, the new Tesla price combined with the US subsidy amounts to a discount of 31%.
In China, where Tesla cut prices last week by 6% to 13.5%, owners protested at delivery centres, calling for compensation.
Before the cuts, Tesla inventory in the United States, as tracked by models its website shows as immediately available, had been trending higher.
