Hypermilers: Smart People or Manic Morons?

| суббота, 26 сентября 2009 г.

I have a friend who drives his Audi S5 like Wayne Gerdes drives his Honda Insight. This I found particularly strange since LG used to make a practice of driving mountain roads like a madman. Then what the hell did he want an S5 for, you may wonder. LG has owned a lot of high-performance cars over the years but now gets his kicks from watching the fuel consumption display (FCD). So, apparently, do a lot of people.

Wayne Gerdes, if you’re not aware, is probably the world champ hypermiler, and he uses techniques like going 50 mph with his right tire on the white line, drafting trucks with the engine off, coasting wherever possible, no A/C, no windows open, no braking, etc. And of course he constantly monitors his progress on the FCD.

Now we’re going to get something even better than the FCD, as Ford and Honda will be offering (in the spring) techy green gauges to give instant feedback on your driving style as well as the usual mpg information. Honda’s EcoAssist display, to be available on the Insight, can even adjust transmission and engine speeds for max efficiency. Ford’s SmartGauge, for the Fusion Hybrid, tracks coolant temperature, driving efficiency and has a vine with leaves that wilt if you drive too fast or furiously.

The case for hypermiling is pretty obvious, even with declining gas prices. You can get at least a 35% increase in fuel economy by simply practicing these techniques: recording your gas mileage, braking less, turning off the engine at long red lights, keeping your distance to counter traffic jams, and accelerating slowly, using cruise control. The idea is to keep aware of traffic and anticipate conditions. See more suggestions here.

Well, what’s wrong with this picture? If everyone drove like this, we could be off foreign oil, traffic deaths would plummet, the planet would be saved. But we don’t drive like this, as the author of the Wayne Gerdes piece found:

Two nights earlier, on a clammy 80-degree Chicago evening, I wait for Wayne at the curb at O’Hare International Airport. I first see his technique as the car he’s driving, a 2006 Honda Civic Hybrid, pulls over to pick me up. Drifts over, actually, like a jellyfish. Around Wayne is madness in motion: Drivers in four lanes are accelerating hard, weaving erratically, or grinding to a halt. To Wayne, these are the driving habits of the ignorant and the wasteful—which is to say, nearly all of us. Wayne’s car glides to a stop as if it has run out of gas. Wayne has stopped without braking.

Many, including yours truly, feel that such driving creates nothing but hazard for the rest of us, not to mention the driver. Here’s a description of how Wayne exits the freeway:

“Buckle up tight, because this is the death turn,” says Wayne. Death turn? We’re moving at 50 mph. Wayne turns off the engine. He’s bearing down on the exit, and as he turns the wheel sharply to the right, the tires squeal—which is what happens when you take a 25 mph turn going 50. Cathy, Terry’s wife, who is sitting next to me in the backseat, grabs my leg. I grab the door handle. As we come out of the 270-degree turn, Cathy says, “I hope you have upholstery cleaner.”

I guess there’s a middle way in all this, and not all hypermilers, including my friend LG, are as manic about the practice as Wayne. But I doubt that high-tech gauges are going to civilize anybody.

Hypermiling on the public roads is madness. Do you agree? Leave us a comment.

What are the best and worst cars produced by the Big 3?

| четверг, 10 сентября 2009 г.

 

Hey, it's reliable, comfortable and practical!

Hey, it's reliable, comfortable and practical!

There’s an interesting topic floating around in the blog-o-sphere regarding the best and worst cars Ford, GM and Chrysler have ever produced.

While hearing comments on Corvettes, Mustangs, Pintos and Chevettes might be mildly interesting, I think it would be WAY more interesting to hear what the best and worst cars are from the last 5 years.

I’m not just talking the ugliest or sexiest, but overall best and worst vehicles the Big 3 have produced since the 2003 model year.

Some of the best that come to my mind are the new Cadillac CTS, Chevy Malibu… heck I’ll even give props to the Caravan. Some that might be on my worst list might be the Ford Escort, Chrysler Sebring and the fifth generation Pontiac Grand Am.

I’ll wait to build an official list though until the brilliance of the CarGurus community shines through and shares their thoughts…It’ll be interesting to see what models are mentioned the most often!

What do you think are the best & worst cars introduced by the U.S.’s Big Three automakers since 2003?

The U.S. really can't complain about fuel prices

The U.S. really can't complain

I want to respond to a comment left about a recent blog.

In that blog, I said that since U.S. gas prices are going down so much, I’m second-guessing my commitment to breaking our addiction to oil. Here’s the comment I want to address:

“Feel lucky that you are not paying the prices around Britain, as you wouldn’t be able to run your car. Based on your 11 gallon car, you would have to pay approx $71 at the current price of fuel over here to fill your car. Maybe you shouldn’t complain so much about the price of fuel as you have it a lot better than most other western countries around the world, and we are all struggling too.”

OK, point taken. I understand that fuel prices in Britain are MUCH higher than in the U.S., even when U.S. prices were near $5 per gallon. We’ve been spoiled on this side of the Atlantic for years, and I’m sure those in Britian and across Europe were thrilled to watch us go into panic mode as our prices skyrocketed. Now that our prices are headed south again, I’d imagine there’s a little jealousy that their prices remain high.

To the person who wrote the comment, and to everyone in Europe: Yes, our fuel prices are lower than yours. But at least your prices have fueled a stable and even enviable auto industry, while our prices have led to the likely demise of ours. You have Porsche, Audi, Mercedes, BMW, Ferrari… should I keep going? We have Chrysler.

What do you have to say about that?

Is there such thing as an 8-speed transmission?

| вторник, 25 августа 2009 г.

 

The Genesis may be a candidate for Hyundai's new transmission

The Genesis may be a candidate for Hyundai's new 8-speed transmission

No one can argue that the best way to save fuel is to build cars that use less of it.

The first function of fuel economy is weight: the lighter the car the higher the MPG.

The second function is RPM. The more an engine revolves per minute, the lower the MPG the car achieves.

Since there’s a limit to how light a car can be, I’ve always wondered why cars didn’t have an extra gear or two for highway speeds. At 70 MPH, my 5-speed manual Suzuki SX4 gets about 25 MPG. Why not have a sixth gear so I could decrease the engine speed and achieve 30+ MPG? Sure seems like I could save a lot of gas cruising the highway at 2000 RPMs rather than 4000.

Enter Hyundai.

The Korean car company has recently announced the production of an 8-speed automatic transmission, for introduction in 2010. Designed to maximize engine torque and improve fuel efficiency, vehicles equipped with this tranny should see a dramatic improvement of highway MPG ratings.

I believe technology such as this is the immediate answer to decreasing our use of oil, and applaud Hyundai for their forward thinking.

What makes the most sense to you: efficient gas-powered cars or hybrid/alternative fuel vehicles?
