Rideshare firm Lyft and General Motors have announced the expansion of their 'Express Drive' short-term vehicle access programme to California and Colorado, to include the 2017 Chevrolet Bolt EV.

Launching in San Francisco in the summer of 2016 and in Los Angeles later this year, Express Drive's California members will have access to vehicles from the largest electric vehicle fleet in ridesharing, including the 2017 Chevrolet Bolt EV (available late 2016) and the extended-range electric 2016 Chevrolet Volt. Express Drive will also launch operations in Denver by the autumn of 2016.

In San Francisco, Los Angeles and Denver combined, over 130,000 people who applied to become Lyft drivers but didn't have qualifying cars will now have the opportunity to drive on the platform.

The expansion follows launches in Chicago, Boston, Washington D.C. and Baltimore.

"Expanding Express Drive provides opportunities to hundreds of thousands of new potential Lyft drivers and continues to make car ownership optional for both drivers and passengers" said John Zimmer, Lyft's president and co-founder. "We are also excited to be adding electric vehicles to Express Drive, which is an important milestone for Lyft and the industry."

GM President Dan Ammann said: "We are very pleased with the success of Express Drive and how quickly the team implemented the program since our alliance was announced earlier this year. The Chevrolet Bolt EV and Volt are a perfect fit for ridesharing offering very low operating costs and a wide range of connectivity features for both drivers and passengers."

Lyft claims to be the fastest growing rideshare company in the US.

In January GM said it will invest $500 million in Lyft's latest funding round to "help the company continue the rapid growth of its successful ridesharing service". The two companies also announced a long-term strategic alliance to create an integrated network of on-demand autonomous vehicles in the US.
