Is The Tesla Model X The Hummer Of Electric Cars?

Tesla catches fire in France

Tesla catches fire in France

Another Tesla goes up in smoke. I’ve written about some of the other incidents here and here.

When I built my electric bicycle back in 2007, I had been waiting for a battery that was less volatile than what had been available. I didn’t want to risk having a fireball under my seat. Tesla traded volatility for power density.

I think electric cars are great for all kinds of reasons, which is why I bought one in 2011. But like any car, they are not created equal, and as marketers begin the process of differentiating them to get us to buy them, that inequality will grow and diversify as it has for conventional cars. And for any fellow electric car enthusiasts out there who think electric cars are going to make a significant dent in carbon emissions in the foreseeable future, read Robert Rapier’s article on that subject. Even a strongly biased study by the UCS shows that electric cars, on average, presently produce about half of the emissions of conventional cars in a cradle-to-grave analysis. Eliminating fossil fuels instead of nuclear from our energy mix will improve that over time. CONTINUE»

Does the 2016 Chevy Volt Really “Seat Five?”

Answer …not really. More on that later.


Chevy Cruze and Volt

I was hoping to see the Chevy Bolt and Tesla Model X at the Seattle car show but the Nissan Leaf was the only all-electric car I saw on display this year. Nissan hasn’t messed with the Leaf’s look yet but the range on its SV and SL models has been improved about 22% (for a price). CONTINUE»

Update on the Tesla Model S

Has anyone else noticed how much a Tesla Model S looks like a Jaguar XF (pictured below)? One of my neighbors drives a Tesla Model S. I was following him down the street a few weeks ago and heard his tires squeak three times in two blocks. Adequate acceleration to maneuver in traffic can enhance overall safety but too much acceleration potential can be dangerous, especially in the wrong hands. Not sure I’d want that temptation.

Fast Chargers

Tesla is dead on with their promotion of fast charging stations. The ubiquitous 240 volt chargers are next to worthless simply because they take too long. A high voltage fast charger can provide a significant charge in a matter of minutes. I recently deliberately drove my Leaf beyond its range because we needed two cars to get supplies to a wedding. My plan was to stop at a charge station on the way home for a few hours to get enough charge to finish the trip. The rest of the family came home in our Prius.

Nissan Leaf Replacement Battery for $5,500


Provision of an after-market battery pack is another electric car first and an all important step for electric cars to gain greater market share. Leaf owners now have the option to upgrade to a new battery (with new, more heat resistant chemistry) when the old one wears out, or of selling their car and letting someone else put a new battery in it. An electric car with a worn out battery wouldn’t have much resale value if you couldn’t replace the battery. The existence of a reasonably priced battery replacement might stimulate sales by putting at ease any prospective customers concerned about how they would sell their electric car once its battery wore out.

Are EVs More Prone to Fires Than Gasoline Cars?

Concerns Prompted by Tesla Fires

Several vehicle fires involving Tesla’s new high-end Model S sedan have attracted a great deal of media scrutiny. Two of the three reported incidents are now under investigation by the National Highway Traffic Safety Administration (NHTSA). Yet while the company’s founder, Elon Musk, is certainly correct in indicating that gasoline vehicles are involved in the overwhelming majority of vehicle fires, including most of those resulting in fatalities, the statistical comparison he has provided in interviews got me curious enough to track down the data for myself.

How Often Do Gasoline-Powered Cars Catch Fire?

The statistic that caught my attention was that Tesla suffers an average of one fire per 6,333 cars, versus a rate of one fire per 1,350 gasoline-powered cars. I’ve been driving for four decades and have probably observed several million cars on the road in that time, yet I’ve only seen a handful that were burned-out following accidents to the extent of the recent Tesla fires. I sensed something wrong, or at least counter-intuitive about the figures cited by Tesla.

Some Thoughts on the Second Tesla Model S Fire

Like the Hummer once was, the Tesla is a status symbol (but for a different crowd). Considering its outrageous price tag, one would be hard-pressed to argue that it is a practical car for the masses. But that’s OK with me, because the Tesla is an ambassador for all electric cars through a process called “status by association” (which is what name dropping is all about). We are social primates… like it or not, status seeking is built into our genes.

On the flip side, it could harm the image of electric cars if this latest trend of catching on fire continues, or accelerates. I’ve looked into the statistics and have concluded that, to date, a significantly smaller percentage of Tesla’s catch on fire than conventional cars. Although, that could change with time. Two spectacular fires in almost as many weeks is not a good thing. A lithium fire with exploding batteries is something to behold and makes good copy. It’s also dangerous if the driver should be incapacitated. To date, no Nissan Leaf has caught fire. 35,000 Leafs have been sold in the U.S. compared to 15,000 Tesla Model S sedans. But that might change as well.

Perspectives on the Tesla Fire


All conventional cars have the potential to catch on fire. A few years ago I ran over some bricks in the road that did $2,300 worth of damage to my car’s undercarriage and spilled gasoline all over the road. This Tesla caught fire a few weeks ago a few miles from my office. Just thought I’d share some differing perspectives I found on the subject:

From Tesla:

“… a Model S collided with a large metallic object in the middle of the road, causing significant damage to the vehicle. The car’s alert system signaled a problem and instructed the driver to pull over safely, which he did.”

From the Kent Regional Fire Authority crash report:

 ”Driver stated that he hit an object in the HOV lanes of SB 167. The car started to run poorly and he pulled off the freeway.”

Testing the Electric Car Battery Warranty Waters

Before the Chevy Volt (a plug-in hybrid) went on sale, Volt Chief Engineer Andrew Farah openly acknowledged that the extreme temperatures found in the Southwest have the potential to permanently reduce the battery pack’s capacity to store energy:

“The Volt may not be right for everyone. If you live in the Southwest, depending on how you use your car, the Volt might not be right for you.”

So what is a manufacturer to do if a given customer’s driving habits consistently exposes his or her battery pack to excessively high temperatures in a place like Tucson, or charges it five times a day, or maybe applies a blowtorch to it? As it turns out, the answer depends on what the warranty says, not so much on what the owner’s manual warns you not to do.

Electric Vehicle Charging and the Range Anxiety Myth

Bosch has just entered the EV charging market with its simple 240 volt Power Max charging station for $499.00. Considering that dishwashers, clothes dryers, and hot water heaters can cost less than that, you can bet that the price for this small, relatively simple device will eventually be a lot lower. The Ecotality Blink charging station in my garage cost about $1,200. Neither is actually a charger. They are devices that interface with the charger carried inside the car. How fast you can charge with 240 volts is ultimately limited by the charger that came with the car. The difference is that the Blink station interfaces with the internet, allowing the DOE to study my charging habits, which is fine by me because they paid for it.

The Ecotality Business Model

Ecotality is also installing Level 2 (240 volt) charging stations in business parking lots. For now, charging is free but eventually you will be charged for your, ah, charge. I don’t see this business model having a long-term future. An analogy might be a company that designed a hitching post tailored for Henry Ford’s first car design (that looked a lot like a buggy) which might have seemed like a great idea by car and saloon owners until they realized you don’t need a hitching post for a car.

Hofmeister: An Energy Plan for America

Can Oil Supplies Grow Fast Enough to Keep Prices in Check?

I, along with my editor Sam Avro, recently conducted a broad-ranging interview with John Hofmeister, former President of Shell Oil and currently the head of Citizens for Affordable Energy, a non-profit group whose aim is to promote sound U.S. energy security solutions for the nation. In the first part of this interview Mr. Hofmeister spoke of A Difficult Decade Ahead For Oil Prices and Supplies. In this installment, he sets forth his vision of a sound energy policy for America.

The Hofmeister Energy Plan

Mr. Hofmeister’s plan consists of the following elements:

  • Set a national objective in the United States to get back to the production level of the 1970s and 80s of 10 million barrels a day;
  • Reduce our imports by 5 million barrels a day by using natural gas as an alternative to the internal combustion engine oil products:
    • Use compressed natural gas for trucking to displace 2 million barrels a day of imported oil, and,
    • Convert natural gas to methanol for flex fuel engines to reduce imports by another 3 million barrels a day;
  • Continue the journey toward more higher efficiency automobiles and continue the journey to more electrified vehicles as well, both batteries and hydrogen fuel cells.
