Tesla Inc.’s long-awaited debut in India has so far produced disappointing results, and the company’s weak bookings have raised new concerns about its prospects for international expansion.

Since starting sales in mid-July, the Elon Musk-led electric vehicle manufacturer has received orders for just over 600 vehicles, which is less than what the business had anticipated, according to people familiar with the situation. During the first part of the year, Tesla delivered about that many cars per four hours worldwide.

According to various news reports, Tesla now intends to send 350 to 500 cars to India this year, with the first batch expected to arrive from Shanghai in early September. Reports further stated that deliveries will initially only be made to the cities of Mumbai, Delhi, Pune, and Gurugram. The size of the cargo depends on both Tesla’s capacity to deliver outside of the four places where it now has a physical presence and the complete amount of money it has received for the cars.

According to a previous report, the company’s initial goal was to use its whole 2,500-car yearly allotment this year.

In order to enter India’s fledgling EV market, the company was relying on its strong brand and its CEO’s once-friendly relationship with Donald Trump. However, Musk’s public outburst with the US president, deteriorating bilateral relations, high local import taxes, and the harsh realities of a price-sensitive market have all turned that equation upside down.
