Elon Musk Publishes Logs Of John Broder’s Drive With The Tesla Model S

A few years ago, popular automotive show Top Gear made Tesla Motors look bad.  They made it look like the car ran out of energy and pushed it back to the garage.  After that experience, Tesla Motors CEO Elon Musk ensured that the company carefully logs drives.  Top Gear had written a script before they even received the car — Tesla Motors found a copy of the script on a  tablet while the car was being “tested.”  John Broder of the New York Times wrote a scathing review of the Model S and so Musk published the logs of Broder’s drive.  Below are some of the facts as published on the Tesla Motors blog:

  • As the State of Charge log shows, the Model S battery never ran out of energy at any time, including when Broder called the flatbed truck.
  • The final leg of his trip was 61 miles and yet he disconnected the charge cable when the range display stated 32 miles. He did so expressly against the advice of Tesla personnel and in obvious violation of common sense.
  • In his article, Broder claims that “the car fell short of its projected range on the final leg.” Then he bizarrely states that the screen showed “Est. remaining range: 32 miles” and the car traveled “51 miles,” contradicting his own statement (see images below). The car actually did an admirable job exceeding its projected range. Had he not insisted on doing a nonstop 61-mile trip while staring at a screen that estimated half that range, all would have been well. He constructed a no-win scenario for any vehicle, electric or gasoline.
  • On that leg, he drove right past a public charge station while the car repeatedly warned him that it was very low on range.
  • Cruise control was never set to 54 mph as claimed in the article, nor did he limp along at 45 mph. Broder in fact drove at speeds from 65 mph to 81 mph for a majority of the trip and at an average cabin temperature setting of 72 F.
  • At the point in time that he claims to have turned the temperature down, he in fact turned the temperature up to 74 F.
  • The charge time on his second stop was 47 mins, going from -5 miles (reserve power) to 209 miles of Ideal or 185 miles of EPA Rated Range, not 58 mins as stated in the graphic attached to his article. Had Broder not deliberately turned off the Supercharger at 47 mins and actually spent 58 mins Supercharging, it would have been virtually impossible to run out of energy for the remainder of his stated journey.
  • For his first recharge, he charged the car to 90%. During the second Supercharge, despite almost running out of energy on the prior leg, he deliberately stopped charging at 72%. On the third leg, where he claimed the car ran out of energy, he stopped charging at 28%. Despite narrowly making each leg, he charged less and less each time. Why would anyone do that?
  • The above helps explain a unique peculiarity at the end of the second leg of Broder’s trip. When he first reached our Milford, Connecticut Supercharger, having driven the car hard and after taking an unplanned detour through downtown Manhattan to give his brother a ride, the display said “0 miles remaining.” Instead of plugging in the car, he drove in circles for over half a mile in a tiny, 100-space parking lot. When the Model S valiantly refused to die, he eventually plugged it in. On the later legs, it is clear Broder was determined not to be foiled again.

The car was given to Tesla in order to focus on future advancements in their Supercharger technology. Last year Broder published an article about how he believed that electric cars are “the victim of hyped expectations, technological flops, high costs and a hostile political climate.”
