Default German government says no to autobahn speed limits

German Chancellor Angela Merkel has told reporters her government would not try to impose any speed limits for the unrestricted sections of the autobahn despite members of her party backing a proposal to introduce a general speed limit of 130km/h (80mph). When questioned about the proposal on German television, Merkel’s response was a straight forward “it won’t happen with me.”

Concerns over the level of carbon-dioxide emissions from cars traveling at very high-speeds has led policy makers to put an end to the traditional speed unlimited stretches of Germany’s highway. Earlier this year, EU Environment Commissioner Stavros Dimas suggested introducing a speed limit but the idea fell out of the spotlight following strong protest from many German residents, reports The Associated Press.


Merkel’s suggestion for reducing carbon emissions is to improve traffic flows and cut down on the number of traffic jams that often clog the autobahn. Something we’re sure most readers would agree is the better solution.

It will be a sad day if/when the entire autobahn gets a speed limit.

I propose mass suicide for all of those that proposed reducing the speed limits--the death of those folks would be a good reduction of CO2... .

OK, I propose that the closest you'll get to that is a politician will tell you he'll build one just to take your money and then not do it.

That's basically how that works here in the States.... where have you been at?

Well actually no, because the higher your rpm the more gas you are burning. The more gas you are burning the more CO2 you produce.

No, it primarily has to do with the fact aerodynamic drag goes up 4 times as fast as your speed.

So say it takes 20hp to overcome aerodynamic drag at 50mph. At 100mph, it takes 80hp to overcome aerodynamic drag.

Fuel consumption is fairly linear with respect to horsepower output, this means that an engine will consume about 4 times as much fuel to travel 100mph instead of 50mph.

Since aerodynamic drag is the primary friction source at high speeds, you can estimate that going 100 mph instead of 50 mpg will nearly double your fuel consumption.

Yeah but you'll spend half the time on the road!

Really, then why does my mpg from highway (80mph around here) or backroads, say 40-45mph, not change much?

Having been on the autobahn and seeing how they drive, it would be a shame to have limits.

some people here in the States have trouble driving at 40mph (posted speed limit)

if we get a highway without speed limit there will still be douchebags doing 55mph in the "fast lane"

screw that ****.

It makes zero sense that you get the same gas mileage at 40 vs. 80. I call shenanigans!

Hence requiring special license to drive on that road. I think it's a good idea, it'll screen out most of the tards on the road.

it should be spread across the entire nation too. Like normal drivers, they can drive on limited amount of roads, restricted to certain lanes and while the higher level ones can do more stuff.

I was thinking the slower you go the more C02 builds up in a single area then going faster.

At 40-45 mph, you are either lugging the engine in 5th gear, or have it in 4th. Lugging the engine or not using top gear will eliminate any fuel economy gains you pick up. In most cars, between 45-55 mph is where top fuel economy is achieved. My best mileage ever was 32 mpg when I drove a whole tank a very constant 50-60 mph. Have never matched it again, all other trips doing ~75 mph get me around 27 mpg.

I'm sure that someone with a Scangauge could easily verify this on a flat stretch of road.

Uhh.... only if by going slower you drop to a speed where your fuel economy goes back down.

These are fairly typical speed vs. fuel comsumption graphs.
x-axis = speed in km/h
y-axis = fuel consumption in liters per 100km

Last I heard the autobahn is becoming traffic-clogged anyway so the need for speed limits is a moot point.

Yeah, I was on the autobahn about a month ago, and compared to the same stretches of the road the previous year, there was a lot of construction thus a lot of slow downs. However, it still moves better than any interstate here in the U.S. The biggest problem with traffic here in the states is peoples refusal to use the number 1 lane (fast lane, left lane, what have you) for passing only. Especially here in NJ, where people will get over there and just cruise at or below the posted speed limit. Also, all the young knuckleheads who zig zag through traffic and pass on the right. Both of which are illegal in Germany. I the state police would spend less time pulling over those who know how to drive for "speeding" and instead pull over those who don't for "cruising the left lane" or "unsafe passing" traffic would move much more smoothly.

Well I think the problem is that first off, they probably make more money with speeding and reckless tickets. Secondly, cruising in the left lane and unsafe passing probably aren't big offenses unless they can be charged with some sort of reckless driving. The judge is probably going to throw those cases out anyway. The third thing is, it might take some major changes in the law, and of course nobody wants to spend time or money on that.

Finally education of our new and young drivers sucks, and once again, people just rather not waste money. They rather just sit in traffic and get in accidents

I did not say the SAME mileage, does not change much...maybe 10%, but no where near your claim of 50% less.
