Data released by Tesla Motors late Wednesday night directly contradicts a damning review of the automaker’s Model S sedan by the New York Times.
The data, pulled directly from the electric sedan’s on-board computer, claims that New York Times reporter John M. Broder never ran out of energy during his extended drive of the Model S, despite his account to the contrary.
Broder’s trip in the Model S began outside of Washington D.C., up to Norwich, CT and then down to Milford, CT over the course of two days. The drive was intended as a way to evaluate Tesla’s newly installed Supercharger stations, which allow Model S owners to top up their batteries for free at solar-powered charging stations lining major thoroughfares along the east and west coasts.
According to Tesla, Broder was given explicit instructions for his drive: keep the speed at 55 mph and turn down the climate control. Broder claims to have set the cruise control at 54 mph and at one point writes he, “limped along at about 45 miles per hour.” However, the logs released by Tesla show that he drove at speeds ranging from 65 to 81 mph, and kept the interior temperature at 72 degrees, increasing it to 74 degrees at one point.
Tesla’s data claims that Broder never completely charged the Model S during three separate charging sessions, including one charge before the final leg of his trip, when Broder disconnected the charger with an indicated range of 32 miles, despite planning to drive 61 miles. Additionally, Broder claims to have charged for 58 minutes during the second leg of his trip, although Tesla’s data alleges it was only connected to the Supercharger for 47 minutes.
While driving on the highway, Broder says the Model S’ display informed him that it was about to shut the car down. “I was able to coast down an exit ramp in Branford, Conn., before the car made good on its threat,” Broder describes in his story.
According to Tesla, the Model S never shut down as was implied by Broder – he simply pulled over. Tesla claims that its “State of Charge” log shows that the battery never ran out of energy at any point during his trip.
The automaker is also questioning the length of a trip Broder made through Manhattan, reportedly giving his brother a ride in the car, as well claiming that the writer drove around in circles outside a Supercharger station for malicious reasons.
Tesla’s data dump comes five days after Broder’s report appeared on the New York Times site. Three days later, Tesla co-founder and CEO, Elon Musk, took to Twitter to refute the story, going so far as to call the New York Times‘ piece a “fake“.
The chemistry of the lithium-ion batteries in the Model S are affected by cold temperatures – especially the sub-freezing temps Broder experienced during his drive – which would reduce the overall range of Tesla’s electric sedan.
In an earlier statement released by the newspaper, the Times stood behind Broder’s portrayal of the drive, calling it “completely factual” and stating that “[a]ny suggestion that the account was ‘fake’ is, of course, flatly untrue.” Calls for a follow-up statement from the Times and Mr. Broder have gone unanswered.
