We have a winner for Tesla’s Next Gen Roadster. Model S owner and host of Teslanomics, Ben Sullins, has referred over 50 Model S and X sales in Tesla’s latest referral program, giving him the opportunity to “buy” a Founder’s Series next generation Roadster at a 100% discount. Simply put, it’s free.

Referral program participants that gifted 5 or more Model S and X buyers with $1,000 discounts and free Supercharging first got wind of a Next Gen Roadster in July, after receiving a notification in their Tesla app that a new Secret Level had been unlocked.

“You’ve unlocked the first secret level. Refer 5 more friends for the ability to purchase a Founder’s Series next gen Roadster at a 10% discount. Unlock new levels with every 5 referrals for an additional 2% off per referral and amazing adventures that money can’t buy.” read the description for Secret Level 1 in the app’s “Loot Box”.

In addition to winning a Maximum Plaid Tesla that could possibly achieve 0-60 mph in 2 seconds or less, Ben also won the rare opportunity to drive The Boring Company’s electric tunneling machine. If you’re not eating sour grapes at this point, take note that the Tesla-focused data geek also won an invite to Tesla’s upcoming Semi truck unveiling event.

But before you take that bite, pause for a second and realize that Ben’s achievement is quite remarkable. Within a matter of months, his YouTube channel has seen unprecedented growth and popularity within the Tesla community, likely because of his talent to turn data-driven content into something digestible and entertaining to watch. Ben also brought us the Model 3 monthly payment estimator among other widely used Model 3-focused tools within the community, further increasing his popularity within a segment that was starving for all things Model 3 related. But arguably Ben’s most notable achievement was his ability to convert the Teslanomics fandom into 55 referred sales or over $5,000,000 in revenue for Tesla in a matter of months.

When we asked Ben for confirmation of his referrals, he not surprisingly plotted the data and sent us the following chart.

Ben also pointed us to some interesting data that’s listed on Tesla’s leaderboard. Based on the 55 referral sales that he made, he’s helped offset 47,275 lbs of CO2 from being emitted and 4,498 gallons of gasoline from being burned.

Los Angeles, San Jose and San Diego currently rank as the top 3 cities in the U.S., respectively, that saved the most CO2 by Tesla owners. The U.S. leads China by roughly four times the amount of carbon emissions saved by Tesla drivers.
