Tesla Motors fires back at NY Times John Broder over failed Model S test drive
On Wednesday evening Tesla Motors CEO Elon Musk posted a response to John Broder's Tesla Model S review in last weekend's NY Times. That review portrayed the Model S as unable to finish a simple road trip, while Musk's response, with its detailed data, instead claims that Broder's article was very inaccurate, or worse. While Musk praises the NY Times for its reputation for honest and fair reporting, his blog post describes Broder's article as inaccurate or a fabrication and calls on the NY Times to investigate.
Broder's article was ostensibly meant to be to test the Tesla Model S on a fairly typical road trip, from Washington D.C. to Connecticut, and back. We went over the trip previously in NY Times' writer Broder makes EV rookie mistakes on failed Model S road trip. The short version of the story is that he traveled from Washington D.C. north, stopping at the Supercharger stations in Delaware and Milford Conn. along the way. These Supercharger stations were installed in December and are the first part of the Supercharger network on the East Coast. Eventually the Supercharger network is meant to allow owners of the Tesla Model S, Model X and future Tesla electric cars, to drive coast-to-coast on electricity. It would be more than interesting to see careful testing of Tesla's claims for that network.
Broder made several mistakes along his trip such as not ensuring the car was fully charged at critical parts of the trip. He ended up in a not-terribly-remote part of Connecticut (Norwich) with insufficient range to make it back to Milford. He ended up stranded on the side of the highway, and was able to take a picture of the Tesla Model S on a flatbed tow truck.
On Monday, Elon Musk took to Twitter and a CNBC interview to slam Broder's article, promising a detailed blog post. Which was not published until Wednesday afternoon. That blog post tells a story similar to the conclusions we drew in the article linked earlier ("EV rookie mistakes") but has detailed data to back up the reasoning.
That blog post makes a list of claims that run counter to what Broder claimed. Each side in this argument has made claims, the question is which side is correct and are either of them purposely fabricating evidence?
A key fact remains in all the details printed below. Broder only recharged to 73% at the Milford Supercharger station. If his intent was to travel to Boston, the route he chose was 163 miles, and a 90% recharge would have given the car a 242 miles range, and a 100% recharge would have given it a 260+ mile range. That would have ensured a comfortable arrival in Boston. In addition, Broder could have chosen a different route to Boston, that required fewer miles, and had more public J1772 charging stations to use as a backup charging solution. For some reason Broder failed to do any of that, and it isn't explained why by either himself or Tesla.
The Model S driven by Broder never completely ran out of energy. Broder claimed that his Model S locked up so badly the tow truck driver had to drag it onto the truck, and then had to spend 20 minutes at the Supercharger before the car would turn itself on sufficiently enough for the car to roll off the truck.
The final leg of Broder's trip was a 61 mile distance, but he unplugged the charging cord when the estimated range remaining was 32 miles. This is one of the rookie mistakes we mentioned earlier. What Musk claims is that his choice to unplug the charging cable was expressly against advice from the Tesla service department.
Musk claims that on the final leg of Broder's trip he drove right past several public charging stations. He had a dashboard warning him emphatically to stop and charge. He could easily have stopped at any of these charging stations to do some charging. One is at the Saybrook Inn in Saybrook, there is a car dealership also in Saybrook with a charging station, the East Haven Town Hall has one, and there is one in New London not too far off the route he took.
Broder claims that early in his trip he set the cruise control to 54 miles/hr, and at times drove as slow as 45 miles/hr on the freeway. Musk claims that the vehicle data logs show the cruise control was never set to 54 miles/hr, that he never limped along at 45 miles/hr, and instead drove at speeds between 65 miles/hr and 81 miles/hr. While we can understand the temptation to enjoy the ultra high speed and acceleration of the Model S, it's a matter of simple physics that higher speeds require more energy and if the goal is to complete a long road trip one must not lead foot it.
Broder also claimed to have turned the climate control down, but vehicle data longs show he never did so, had it set to 72 degrees and even raised it once to 74 degrees.
