Bob Lutz Lets Loose on Future All-Electric Volt & Range Surprises


We bid farewell to Bob Lutz as the frontman for General Motors’ (s GM) Chevy Volt nearly a year ago, when he announced plans to retire at the end of 2009 (it didn’t take too long for those plans to change). But the onetime climate change denier is like a cat with nine lives, always coming back with some of the juiciest comments about the Volt and plug-in cars amid the mass of carefully controlled corporate messages.

Here’s the latest: Lutz said at the North American International Auto Show that it’d be no sweat for GM to build an all-electric version of the Volt (the upcoming model is an extended-range electric vehicle — a small gas engine kicks in when the battery runs out of juice), according to several reports out of Detroit this morning. If it’s so easy, does GM actually plan to build this all-electric vehicle? According to the AP’s story, it does. Lutz didn’t specify a date that GM might roll an all-electric model into showrooms, but he said, “Once you’ve done the Volt, pure electric is trivial. You just leave some parts out.”

But while Lutz is already looking ambitiously ahead (what else would you expect from a guy nicknamed Maximum Bob?), he also mentioned to reporters some major potholes in the Volt’s road to electric glory. First, there’s the little snag of variability in how far the Volt can go on a single charge. GM advertises a 40-mile all-electric range for the vehicle, but Lutz said he only got 28 miles worth of juice from the battery when he drove a Volt for a weekend in Detroit this winter. He explained:

“The range can vary on any given day depending on temperature, terrain, driving conditions and so forth — especially temperature…The distance you can go in an electric vehicle varies hugely with the outside temperature, including with the Volt.”

GM’s Andrew Farah, chief engineer for the Volt, noted in a recent press briefing that climate’s effect on battery performance can go both ways: “We have a very sophisticated control system in the vehicle,” he said. “Our biggest challenge is hot weather storage, where we can’t control that environment.” But if you drive the Volt mostly in urban, temperate environments, he said the battery could last “significantly longer” than the guaranteed 10 years.

Another snag Lutz raised at the auto show this week has to do with gas prices. “If the rise in gasoline prices is gradual, I think that all of us in the industry would frankly welcome that, because there is nothing more illogical than forcing fuel-saving technology when gasoline is extremely cheap,” he said, according to a report on

This is one area where Maximum Bob tends to hedge, however. Speaking about the prospect of a gas tax hike last month, he said, “We’re not advocating that but if it doesn’t happen it’s going to be very difficult for these technologies.” This week he took a slightly stronger stance, saying that while he’s not speaking for GM on this, he thinks it would be valuable to steadily raise gas taxes to much higher levels.

Nice article. However, wanted to point out that the “Extended Range Electric Vehicle” (E-REV) is simply an electric vehicle with gas powered a generator that would act as a power source to charge the battery if the battery was running low on charge. Said another way, the E-REV is actually an all-electric vehicle with a generator added on. As such, the E-REV concept is actually superior to an all-electric vehicle as it provides a way to “fill-up” if you ever run out of charge and do not have access to a electric power point. By developing the E-REV, GM addresses one of the main concerns with electric vehicles: what happens if I run out of juice while away from home?


Before anyone fails to laugh at Mark Goldes’ fantastic claims (read plea for funding), please do a quick Internet search on his name. In moments you’ll find that he’s been trolling the Internet with similar nonsense claims looking for investors (read shills) for many many years.

In about five years electric and hybrid cars will demonstrate a dramatic revolution.

See the article The Love Affair with Autos Allows a Seductive Alternative – on the website:

It provides an outline of how future cars might pay for themselves, by employing remarkable new technology that can turn them into power plants when parked.

Visualize electric cars that will need no recharge and hybrid automobiles that will use ordinary water as fuel: One gallon may prove sufficient for 1,000 miles of driving.

Of course, these statements are almost impossible to believe.

Yet, as the article indicates, this new science has begun to be validated by independent laboratory experiments.

And soon, I believe, more will be.

Until then, nobody is expected to accept these incredible breakthroughs as real.

Imagine the implications! The public will line up to buy such cars and trucks. The auto industry will come back to life.

This will change the conventional wisdom about energy.

The real challenge is to accelerate development.

Instead of five years, it could take less.

With an all out effort, perhaps much less!
