Ola landed on the scene in 2011, and has since snapped up more than 125 million registered users and over 1 million drivers across 110 cities in India. Expansion was on the cards following the firm's $2 billion funding round in October, which included investment from China's Tencent and the University of California's investment arm, among others.

Despite the expansion, Uber and Ola's primary battleground remains India, where the former counts 450,000 drivers among its ranks. Ola recently announced plans to take on its rival with a fleet of electric vehicles, including cars and auto-rickshaws.
