MUMBAI, April 23 -- US electric vehicle (EV) maker Tesla has launched a six-seater version of its best-selling Model Y in India as it tries to attract buyers in the world's third-largest car market where it has struggled to grow sales. Tesla has sold just 350 Model Ys in India since starting deliveries in September, government data showed, with rivals including BYD, Mercedes-Benz and BMW far outselling the US company over the same period. Its imported Model Y attracts a steep 100% import tariff, a level that chief Elon Musk has often criticised, meaning Tesla's cars are priced much higher in India than in other markets. With the Model Y L, Tesla aims to tap a wider customer base as Indian buyers, especially families, increasingly turn to larger, premium vehicles equipped with touchscreen displays and sunroofs. This shift has helped propel demand for three-row SUVs in India, a segment currently dominated by Toyota Motor and Suzuki Motor. The Model Y L, which has a longer driving range of 681 km, will be priced at about Rs.62 lakh, equivalent to $66,000. That is only slightly above the $64,000 price tag on the Model Y, but still far above a market where most cars are priced below $22,000....
