The latest round of Tesla’s referral program for owners was supposed to end last night, but the automaker has extended it for two more weeks – maintaining the opportunity for new buyers to get free unlimited Supercharging for Model S and Model X vehicles a little longer.

Just as a reminder, the default Supercharger access model when buying a new Tesla Model S or Model X is already the new pay-per-use model unless the buyer is being referred by an existing Tesla owner, in which case, it reverts to the old unlimited free access model.

Model 3 buyers don’t have access to a referral incentive and therefore, they directly fall under to the new pay-per-use model, which consists of paying per kWh charged from a Supercharger station or per minute of using a station in the states and provinces where Tesla can’t officially “sell” electricity due to local restrictions.

Tesla recently increased the cost of using its Supercharger stations under this model, but the company insist it ‘will never be a profit center.’

Right now, Model S and Model X buyers virtually all use referral codes and therefore, they access Supercharger stations for free.

The benefit is threatened to be taken away after each referral program round, which generally last about a quarter, but Tesla has been reintroducing it every time.

The last round officially started May 1 and it was supposed to end yesterday July 15, but Tesla updated its referral program support page last night to extend the round to July 31.

It results in Model S and Model X buyers still having two more weeks, at least depending on the next round, to get free unlimited Supercharging, and Tesla owners have two more weeks to get more referrals in order to get prizes.

Over the past few rounds, Tesla has been mostly using the same prizes but with different thresholds of eligibility per prizes.

For this round, Tesla owners with up to 5 referrals can get prizes ranging from a special black Tesla Wall Connector to a Powerwall 2.

Speaking of referral prizes, Tesla is behind on the delivery of many of them for previous rounds, but we learned that last week that the long-awaited Powerwall 2 Founders series signed by Elon Musk finally started being delivered.
