CAR drives up H1 net earnings

But road to profits could prove tougher going as Didi gears up launch of online auto rental service

Despite posting a roaring 161 percent year-on-year profit growth in its half year financial report on Tuesday, China's biggest auto rental company CAR Inc may not in the mood to pop the Champagne and celebrate just yet over its booming business.

That's because Hong Kong-listed CAR is expected to see much fiercer competition going forward over market share as China's ride-hailing heavyweight Didi Chuxing confirmed it will launch an online car-rental service, said analysts.
