Well, they made it!
Tesla Model S-driving trio Peter Soukup, Tina Thomas and Luba Roytburd successfully arrived in New York City after almost five thousand miles of driving coast-to-coast.
After starting in Portland, Oregon on December 26, the team drove down the West Coast, before cutting across Arizona, New Mexico, Texas, Louisiana, Alabama, South Carolina, and then up the East Coast.
They announced their arrival in NYC with a Tweet on Monday.
"If I can make it here, I can make it anywhere and we made it! Electric Road Trip S successfully finished in NYC, final mileage 4887!"
The team then thanked Tesla and Elon Musk for "an amazing car".
Over the course of the journey, the team made use of several different charging stations, including Tesla's own Supercharger network, for speedy charging and shorter stops.
Musk himself tweeted about the trip, suggesting that by the end of 2013, "it will be Superchargers all the way!".
Congratulations to the team for reaching their goal. With a few more rapid chargers along the way and electric car range rising all the time, we doubt it's the last such trip we'll be hearing about over the next few years...
