Adds context from paragraph 4
BEIJING, Nov 4 (Reuters) - Tesla's TSLA.O China-made electric vehicle sales fell 9.9% to 61,497 units in October from a year earlier, reversing a 2.8% increase in September, data from the China Passenger Car Association showed on Tuesday.
Sales of the U.S. automaker's Model 3 and Model Y vehicles made at its Shanghai "gigafactory", including exports to Europe, India and other markets, dropped 32.3% from September.
Its biggest Chinese rival, BYD 002594.SZ, 1211.HK, posted a 12% drop in global vehicle sales last month, a second consecutive month of decline and the steepest fall in nearly two years amid hyper-competition in the home market.
Tesla has not yet announced the availability on the Chinese market of the lower-cost versions of its best-selling Model Y SUVs and Model 3 sedans, which were unveiled last month.
In spite of the swift European roll-out of the new cars, which opt out of some premium features, Tesla sales resumed falling in a number of countries there, pointing to continued struggles on a continent that has been crowded with budget EVs.
By comparison, BYD has seen robust sales growth in Europe even while its growth on home turf hit a speed bump.
Tesla is also set to showcase its Cybercab in Shanghai from Wednesday. It remains unknown if Tesla has planned the robotaxi's roll-out on Chinese roads where local firms such as Baidu 9888.HK, Pony.ai PONY.O and WeRide WRD.O have been testing their robotaxis in various cities.
