What's a Chevrolet Volt?

Chevrolet introduced a concept car called the Volt at the 2007 Detroit Auto Show. If you're not a car geek, you may not be familiar with the fact that concept cars are often wildly impractical futurist visions of what a company might do if the laws of physics were repealed... you may have noticed that we still don't have the flying cars promised to us in the '50s, never mind the nuclear reactors in the trunk to power our cars for decades on a single refueling. The Volt Concept was racy-looking, impractically-packaged (for a mainstream consumer car) and described as a series hybrid, specifically GM's E-Flex Extended-Range Electric Vehicle (EREV) system.



If you take a moment to look at that picture, it becomes apparent that the design compromises outward visibility, and if you're seen video or stills of people near the concept, it's not packaged well to be comfortable for 4 people. Never mind the fact that the concept car has a golf-cart powertrain to let it move under its own power, it wouldn't be a practical everyday car even if it had the final production E-Flex powertrain.

Now, a couple of weeks ago GM started leaking pictures of what is to be a production version of the car. Last week that had an official reveal of the production look of the car. The fact that there is to be a production version at all speaks of the upheaval at SUV Central ...er... GM Headquarters over the state of the car market today. Americans have realized that it's not really necessary for one person driving to their white-collar job to drive a vehicle that weighs 6000 lb and has seating for 8, and they've abruptly stopped borrowing against their houses to buy one, so there are Tahoes and Suburbans languishing on dealer lots everywhere.

In a shocking break with recent tradition, GM is planning to offer to the public a vehicle that's more efficient than the current Toyota Prius. A vehicle that will let you drive about 40 miles per day without needing any gasoline at all, and if you need to drive farther than that before you have a chance to plug in and charge it for a few hours, the "extended range" part of the powertrain kicks in and the car will take you as far as you want as long as there are gas stations every 300 miles or so. This is a game-changing powertrain, even if it's not an atomic car. The car that will be produced, as usual, is very much toned down from the show car that has to look good on a turntable but doesn't have to be a good car to drive.



It won't be out for a while (GM is saying late 2010) and there's conflicting info about what it will cost, what tax incentives will be in place at the time, etc. Bob Lutz, Vice Chairman of GM, wanders around with random quotes rattling out of his head and generally contradicts official statements, engineers in interviews and whatever he said last month. He was on Colbert last week and didn't really help the car any, but his interview will be largely forgotten by the time the car's in dealer showrooms.



I am amazed at the number of people who are up in arms over the fact that the production model doesn't look just like the concept car. They stupidly throw out epithets not supported by facts like "Electric Malibu!" and "Hybrid Cavalier" and "bait and switch" and claim they don't want one because it doesn't look exactly like the concept that most of them have ONLY SEEN IN PICTURES. It's a different size and platform than the Malibu (it's slightly smaller than a new Malibu) and obviously has nothing to do with the Cavalier that has been out of production for years. It's larger than the concept and has much more passenger and cargo space, and has significantly less aerodynamic drag, but the mouth-breathing hordes are screaming that GM is cheating them by producing a practical car instead of giving them the show car they got all excited about.

I've posted many times in several threads on this topic that GM needs this car to be a success, and the Camry is a much bigger success than the Solstice, or even the Miata. Bland sells. In the case of the Camry, bland sells like free nickel beer. Once GM proves the technology and turns its finances around, it can be used in many other vehicles and they can produce shorter-range, less-efficient cars for the form-over-function types, but any fool can see that people buying family cars buy lots of 4-cylinder Camrys and Accords and Fusions and Malibus because they make sense, not because they make them horny.

I also included a "tinfoil hat" tag because there's a cadre of people following the Volt's development who claim that we should all be driving around in an EV1 and GM and the oil companies want us to be dependent on oil forever and the Volt isn't nearly as good as the EV1 and GM killed the electric car and on and ON. They can't see that this 4-seater car with decent cargo room, a production-ready chassis and essentially UNLIMITED range is better for most consumers (even with its more limited all-electric range) than a hand-built extremely lightweight 2-seater experiment that was never made available to drivers in harsh climates and required a long charging cycle with a non-standard inductive charging paddle when it reached the end of its range in 80 miles or so.

Should you buy a new mower now?

So, how long will that "perfectly good" lawn mower you've been thinking of replacing for the past 3 summers last you? I've been thinking about that more in the last month or so, because my 12-year-old lawn mower "has issues" but I'm a notorious cheapskate. My first power mower (the same one with "issues") was the cheapest rear-bagger I could find, back when the cheap mowers were under $100 on sale. In recent years, the weird little spring-loaded carburetor can't keep a consistent RPM, but it runs well enough to mow the lawn without stalling (it just sounds like a prop from a 3 Stooges film.) If I buy something new, I'd like it to have a Honda engine and keep it until I'm a grumpy old man paying the neighbor kids to mow the lawn, and you can't get a mower with a Honda engine for $100.

So now I'm torn between spending more than I want for a proven product now, or probably spending WAY more than I want for new tech in a few years. EPA regulations will require cleaner engines on walk-behind mowers in 2011 (the regs tighten for 25+ horsepower equipment in 2010.) So, what do I really need?

For Texas, I have a fairly small lot. I'm not into the big house thing, quality space and location means more to me than square footage. So, electric is an option. I'm not sure what I think of that... the overall technology isn't new (one of my crazy aunts had an electric mower in the early '70s) but some of the new ones are battery-powered. Green tendencies tell me this is a good idea... lower emissions (both total and of course in my neighborhood), quieter, theoretically fewer problems. I've read lots of poor reviews, and don't really know where to find "reliable" lawn equipment reviews. Cords that get in the way, batteries that wear out... but no gas required. The cheap electric string trimmer I bought 15 years ago still works fine, as does the electric blower I bought a year or two after that.

I could buy a new gasoline mower in the next couple of seasons. Now my inner cheapskate is arguing with my inner environmentalist... it would probably run cleaner than my old one but not as clean as one with a catalytic converter after 2011, but it would cost less and if the first few years of lawn equipment with catalytic converters suck as much as the first decade of cars that had them, waiting for a "clean" gas mower might not be a good option.

I have to wonder if I'm subconsciously not deciding because doing nothing is the cheapest option....
