Nov 1 (Reuters) - Tesla (TSLA.O) aims to start mass production of its Cybertruck at the end of 2023, two years after the initial target for the long-awaited pickup truck Chief Executive Elon Musk unveiled in 2019, two people with knowledge of the plans told Reuters.A gradual ramp in the second half of next year to full output for the sharp-angled electric truck would mean that Tesla would not be recording revenue until early 2024 for a full-quarter of production on a new model seen as key to its growth.It would also mean a wait of another year for the estimated hundreds of thousands of potential buyers who have paid $100 to reserve a Cybertruck in one of the most highly anticipated, and closely tracked electric vehicle launches ever.It has not announced final pricing on the Cybertruck, showed the production version of the vehicle or specified how it will manage the battery supply for the new model.The launch of the Cybertruck will give Tesla an EV entrant in one of the most profitable segments of the U.S. market and a competitor to electric pickups from the likes of Ford Motor Co (F.N) and Rivian Automotive (RIVN.O), both of which have launched models in still-limited numbers."
