$Tesla (TSLA.US)$ is enticing potential Model S and Model X buyers in the United States and Canada with an offer of 10,000 free Supercharger miles (or 10,000 kilometers in Canada).

The promotion is valid for customers who accept delivery of their new vehicle between March 25 and March 31, according to Tesmanian. The free charging miles are valid for two years from the delivery date and are non-transferable to a new owner in the event of resale.

End-of-quarter deliveries are a crucial metric for Tesla, with investors closely monitoring these numbers. To ensure strong delivery rates, Tesla is motivating customers to take delivery as quickly as possible. The free Supercharger miles serve as an attractive incentive to expedite the delivery process.

Although Tesla has periodically offered free Supercharging miles to boost sales in the past, the current offer of 10,000 miles is more generous than past incentives. While 10,000 free Supercharger miles may seem like a substantial amount, the value of the offer is roughly $500, as vehicle efficiency and Supercharger prices vary by market.

With recent price reductions in the U.S. and the introduction of new federal tax credits for electric vehicles (although Tesla may lose some of those), this latest incentive could stimulate demand and contribute to a stronger sales figures for Tesla.
