You’ve seen pictures of the Chevy Volt — that thing has been unavoidable for nearly two years now. And it’s always shown in that distinctive space-age silver with a slight greenish sheen. It turns out that paint color is nameless, and Chevy wants you to come up with something clever.

The prize, should your clever paint name win, is to test drive a pre-production Chevy Volt in Los Angeles. Use your coffee breaks to come up with good ideas, then submit them by November 4. Three finalists will be announced on November 16, and the good people of the Internets will vote for the winner, who will be announced on December 1.

The first thing to note about the Nissan Altima Hybrid is that it makes use of the Toyota hybrid system. Nissan is working on its own proprietary hybrid system, but in order to enter the HEV market ASAP, they leased the technology from Toyota and dropped it into the Altima, giving the car an EPA mileage rating of 35 city, 33 highway. Not too shabby for a four-door sedan.

But not too smooth, either. The Altima hybrid has a keyless, push-button start. It only takes a second to turn the car on, and a green “ready” light lets the driver know the electric motor is good to go. A few seconds later, though, whether you need it or not, the gasoline engine kicks in — very noticeably. The first time it happened, I wondered if I had done something wrong.

Since the hybrid system was thrown into the Nissan Altima almost on a whim, the gauges lack the depth of fuel economy information seen in other hybrids. The center gauge does display “EV Mode” when the car is running under electric power only, which makes for a fun mpg challenge for the driver. The key is to stay in EV Mode for as long as possible, or to get EV Mode to kick in while driving around. I found that with careful pedal work, I could do most of my Christmas shopping on electric power. That was cool.

The Nissan Altima Hybrid gets good marks for its safety — five-star ratings for front and side crashes — and its low carbon footprint. But the integration of the hybrid system into the existing Altima leaves a lot to be desired, especially at a base price of $25,070. I assume the Nissan hybrid system of the future will work more seamlessly in its own cars.

When I got back to the States after my vacation in diesel-clogged Buenos Aires, I had a Ford Escape Hybrid waiting for me to test drive. I don’t think I’ve even been so happy to see a low-emissions vehicle in my life.

Before we get to the mpg, a note on space: The Escape fit all of our suitcases, camera bags, backpacks, and whatever else in the back seat and cargo area, with plenty of space for a regular-sized driver (me) and a six-foot-plus passenger. It was far less crammed than the airline seats we had just happily left, and we had satellite radio.

When the Escape is started, the gasoline engine comes on, so there is an audible cue to let the driver know when to stop turning the key. In case that’s still too quiet for you, there’s the little green car-shaped light with a double-ended arrow under it in the dashboard to let you know the vehicle is ready to go. (This comes in handy when stopped at very long red lights and the gas engine drops out. The electric motor is silent, but ready to do your bidding at the green light.)

The home screen of the display has a little map, radio information, and an mpg meter. For more detailed mileage information, you can call up the HEV screen, which shows a diagram of the engine, electric motor, the battery, and the front wheels. A green outline shows which elements are in play at any time, and the status, i.e., “Idle with Charging,” is spelled out at the bottom of the screen.

The Escape doesn’t have the pep of the Mini I tested a few weeks ago, but I did take it on a variety of roads — surface streets, interstates, and state roads. No matter what I did, I couldn’t get my average fuel economy to budge from 30 mpg. Wait — I did get it to 29.9 mpg while I was passing a string of trucks. This is less than the EPA combined rating of 32 mpg, but still good for an SUV. The EPA also gives it an 8 out of 10 emissions rating.

That kind of mileage and low emissions come at a price, though: the Ford Escape Hybrid starts at $29,305. Hybrids are still hard to find on the lot, as they are expensive to build and popular to buy, so price breaks and dealer incentives are going to be equally as scarce for the Escape hybrid. But if you can find and afford it, the Ford Escape hybrid is a great SUV.

In my capacity as an automotive journalist, I have driven the Mini Cooper before. Several times, as a matter of fact. But when the red 2008 Mini with black stripes was delivered on Friday, I had a mission in mind. I was going to put its EPA fuel economy estimates to the test.

The Mini Cooper in my possession for a few days had a standard 1.6-liter, 16-valve, 4-cylinder engine that could turn out 118 hp. It may not sound like much, but in a car this small, it’s enough. It also had a six-speed manual transmission, which would help in the mpg department. The test car did have sport suspension and 16-inch wheels, rather than the regular 15-inchers, but I didn’t think that would affect the fuel economy much. The EPA estimated 28 mpg in the city and 37 mpg on the highway.

The morning the Mini Cooper appeared in my driveway, I was already late for lunch. I grabbed the keys, reset the mpg counter, threw the car in reverse, and tore off in the direction of the restaurant where I would meet a few friends. I did not drive responsibly. Safety was, as always, my priority, but speed came in a close second. I was surprised, on reaching the restaurant a few miles away, that I had still averaged over 32 mpg, even driving like a jerk.

Over the next few days, I drove in a much more sane way around Portland. Lots of in-town driving, some freeway, some stop-and-go traffic at 5:30. It never dipped below 30 mpg. As you can see, after five days of normal driving, I averaged 33.7 mpg. This is above the EPA’s combined rating for the Mini Cooper of 32 mpg.

I have to give the car back, and it’ll be a while before I get another. BMW, which owns the Mini brand, is pulling back on its press loaners for now. In the meantime, we can all look forward to those precious few electric Mini E models coming to the States for real-world testing.
