While the U.S.-China trade dispute, uncertainties about the global auto market and rising costs for developing cleaner cars are common concerns for automakers, the slowdown in India's market has emerged as a new headache.

The slowing Indian economy has taken a heavy toll on Suzuki Motor Corp., which has a strong foothold in the world's fourth-largest auto market through subsidiary Maruti Suzuki India Ltd.

Suzuki's group net profit in the six months to September tumbled 41.8 percent from a year earlier to ¥79.30 billion ($730 million), with sales in India dropping 26.5 percent to 675,000 units.
