Tesla News Flashbacks: 2009–2014

January 12th, 2019 | by Zachary Shahan

I was searching for some old information on the Model X on Friday and I stumbled across interesting old news that made me reflect a bit on Tesla's development. Then I stumbled across more. And then more. So I ended up deciding to put together this piece on some Tesla news flashbacks


Tesla Vehicle Ramp Cycles Getting Shorter (Charts)

January 12th, 2019 | by Zachary Shahan

Twitter user @ElonMuskScience created an interesting chart last year based on Tesla financial data and shared it with us. I thought it was fascinating and worth a long story, but we never got around to diving deeply into the topic (well, I mean, since Maarten did back in May). But the time has come. Here we go!

January 6th, 2019 | by Zachary Shahan

Nearly 2½ years ago, I wrote an article titled “22 Ways To Delay The Electric Car Revolution.” It was hugely popular and led to numerous suggestions for additional methods of delay, so I ended up turning it into a list of 50 "tips" for slowing down the electric car revolution. What has changed since then? Well, read on and see which of these approaches is still relevant


Tesla Autopilot Miles Soaring

January 5th, 2019 | by Zachary Shahan

Tesla Autopilot miles have been soaring as the company has scored insane sales growth in recent quarters. None of those Autopilot miles have been fully autonomous, of course. However, what many Tesla enthusiasts have learned — yet much of the market seems to discount or not know at all — is that Tesla vehicles with Autopilot hardware (which is all new Teslas in recent years) are learning with every tire rotation. The ones with the software enabled must be a learning a bit more, since they are processing how Autopilot thinks it should drive and where and how drivers occasionally correct it, but I'm sure the vehicles with Autopilot latent are still gathering important data


Honda Accord Sales & Civic Sales Drop 80,000 In 2018

January 5th, 2019 | by Zachary Shahan

To start, let me just put this out there: I'm not claiming Honda's car sales are collapsing solely because of the Model 3, even though Tesla Model 3 sales totaled ~140,000 in the US in 2018 and two of the top models buyers were coming from were the Honda Accord and Honda Civic. There has to be more to it than that. Right

January 4th, 2019 | by Zachary Shahan

The electric car story of the year — nay, the car story of the year — was the Tesla Model 3 taking the industry by storm. Just as we were predicting 3 or 4 years ago, Tesla's ability to ramp up production of a more affordable, more mass market model is sending chills down other automakers' spines — or it should be. I'll revise a famous old quote to explain the ongoing story in a different way

January 3rd, 2019 | by Zachary Shahan

In the month of December, Tesla sold more luxury cars than all other automakers. In fact, it accounted for approximately 30% of luxury car sales. Tesla sold more luxury sedans than BMW and Audi combined, more than Mercedes-Benz and Lexus combined. It absolutely crushed the luxury car competition

January 3rd, 2019 | by Zachary Shahan

The Tesla Model 3, adored by millions of Tesla fans from day one (March 31, 2016), was a lighting bolt in the US car market in 2018. The Model 3 has shown why any remaining Tesla critics should really stop doubting the 21st century car company out of Silicon Valley
