(Adds comments by Waymo CEO, details on the company's business plans)
March 2 (Reuters) - Waymo, the self-driving unit of Alphabet Inc, said on Monday it had raised $2.25 billion in its first external investment round and expects to add more outside investors.
The company also disclosed its self-driving trucking business will be called Waymo Via.
Founded 11 years ago as a small project inside Google, Waymo now is widely considered the leader in developing self-driving technology. But Waymo and its principal rivals are still years away from building large-scale businesses around that technology, analysts believe.
Waymo Chief Executive Officer John Krafcik, in a media briefing late on Monday, declined to confirm whether Alphabet plans to sell or spin off Waymo, saying it was "certainly a possibility for the future."
Krafcik described the outside investment as part of "an evolutionary path that we had always imagined" that could lead to "more independence" for Waymo.
He said Alphabet would continue to join other investors in funding Waymo.
In addition to Alphabet, initial investors include auto parts supplier Magna International Inc, with which Waymo has an assembly deal; U.S. dealership chain AutoNation Inc , which services and maintains Waymo's vehicles; the Canada Pension Plan Investment Board, and three large investment firms: Silver Lake, Andreessen Horowitz and Mubadala Investment.
AutoNation said it invested $50 million as part of the initial funding round. Figures for other outside investors were not immediately available.
Waymo did not provide a valuation.
Last September, investment bank Morgan Stanley slashed its projected valuation of Waymo to $105 billion from its earlier estimate of $175 billion, saying the commercialization of self-driving vehicles and technology was taking longer than expected.
Krafcik said Waymo plans to offer a range of self-driving transportation services, from its Waymo One ride hailing business in Phoenix through the new Waymo Via logistics business that would bundle local and long-haul delivery.
He said Waymo, which has partnered with Lyft Inc, Fiat Chrysler Automobiles and Jaguar Land Rover , is considering partnerships with other automakers and transportation service providers in various markets outside North America, but did not provide details.
