yes, that was an actual ad campaign back in the 70s when the national 55 MPH speed limit was rolled out. the basic premise was that your gas mileage suffered more, the more you exceeded 55.
I suspect i may have been accurate at the time: overdrive was only on trucks, so the average car was in top gear between 35 and 45 Mph, and so you had to give it a lot of throttle and spin the engine pretty fast to go above the speed limit.
but was it that true, then, and is it still true, now? we know from having had a professional motorhead among us that an internal combustion engine runs most efficiently at WOT with its speed limited by the load placed on it, and we know that modern transmissions have higher gears. I have maintained that engineers, if they are worth their pay, design the car to operate as efficiently as they can get it to operate, in the speed range most consistent with the speed limit; so it makes sense for them to design their (intended for the US) cars to be most efficient at 65-75 MPH, which is consistent with freeway speed limits in most of the US.
now, of course, naysayers will say "but wind resistance" - the original argument. to which I say, we are not discussing the most efficient speed at which to move a load - we are discussing the speed at which the specific drivetrain of the car moves the load.
I suspect that you will have interesting results from different classes of vehicle. - regarding points at which they suffer efficiency losses just from fuel wasted by driving in lower gears.
the test I have in mind is fairly simple: get cars with a good way to meter fuel usage, drive them on a circle track at different speeds and calculate fuel efficiency at different cruising speeds and carrying different loads. optimally, this would include a range of vehicles from economy electrics to their cargo truck.
they could also tie in tests of rates of acceleration, as measured by accelerometer. I.E. does it take more fuel to accelerate from 0-60 at .1G than at .5G?

With many of the newer cars having fuel consumption readouts that indicate miles per gallon, this should make it much easier to test. From my own personal experience, it seems that the magic number appears to be closer to 65 mph.

From my own experience owning a Cavalier CD, being it was the first mass production car in UK that had a coefficient of Drag that mattered at all in its design, I would suspect quite rightly, the CD value of a vehicle is more important than the engine.
55 is more probably an average of all cars.
But look at the square head on of a Euro-style cab-over against the long nose of a US style heavy truck.
The look at a RangeRover against a Porsche 911.
It natters what vehicle you drive, more than what speed you drive it at?.
My car is most efficient around the 65-70 mark, an early Transit Van more around the 30/40/50 mark, later transits at the greater speeds, as they did more aerodynamic work, and you can get 30 to the gallon out of one with a light loading.
I suspect all vehicles at 55 to be well and truly bust-able, but some more than others, and later vehicles with better aero, greater MPG, and then them SUV bricks, less than acceptable for modern fuel efficiency wishes.
In comparison, a 5seat SUV Landrover Disco against a modern Toyota saloon,[-insert any other favourite make ford chevvy etc...]who wins?.

Most vehicles are designed to get their best aerodynamic affected fuel efficiency somewhere in top gear doing freeway speeds. Thats the whole point of their gear ratio and aero, to get them somewhere they want to get in reasonable time without having to stop every 20 mins for a fuel stop. "Reasonable" speed is now considered legal speeds, because since the introduction of speed limits, cars gearboxes and aero have been tweaked to those speeds. Where "Most cars" is something us mortal normal people drive that have engines that are not built for say more than double the freeway/motorway speeds and are not Bugatti veyron, where 20 mins at full chatter will drain the whole tank, but at over 200 mile per hour, thats a hell of a distance you just covered in 20 mins?. Therefore, the twerps doing 25 in a 30 zone, or even worse for the Yanks, doing 25 in a 35 zone [1], are saving nothing greater than a teaspoon of fuel per wheel-banging dashboard chewing frustrated driver stuck behind them per 20 miles?... Yet they seam to "Delight" in the greater the queue of stuck traffic they cause, it "Empowers" them in some way?. I often wondered if there was some secret forum that they used to all congregate on to boast of their chaos, but even a foray into the "dark web", as much as I trawled the internet, I never found it. To illuminate the phrase I used on "Who wins", I am suggesting the best MPG would be the winner here not who gets there first. So no, this isnt a race, but the winner is those who dont need to stop as often, so a winner is the one who goes the furthest on one tank of gas. This is hyper-mileing at reasonable speeds. And therefore, stick the car on a 55 road and see who goes further at that speed, and again at your Free-way Interstate speed if higher and see who wins there, in UK, this would just be start at the bottom of the M5/M6 stretch and see how far up you can get and if to the top, Glasgow, turn around and start for home, max speed whatever is posted through roadworks or 70mph. "The winner is" who has most fuel left when you get fed up of sitting in roadworks at this time, because the M6 is a bloody nightmare, its being upgraded to 4land per side "smart motorway", as in, where smart is any given description for something that isnt, but enough of the side track, set a stretch of road that is usable and set a steady speed, see who does more MPG. Is a coefficient of drag insurmountable for a drive-train engineer?. Nothing is impossible, miracles just take a little longer and require booking in advance around here. However, cost efficient, I remember back when 4 gears was enough, then now we have 5, some have 6, and when you pay a lot, you can have 7/8/9 to pick the right gear to be in. But all that adds weight. Weight is as much your enemy as a flat front brick of a bodywork. Consider F1... now hows that for getting out there at the extreme?. They have 11 gallon tanks. Approx. I cant tell you for sure as each team differs, its now done by weight, and the soddin rules keep changing, and this is only an example so semantics aint that important?. NO Refuelling now. So up to 3 hrs full thrutch racing on one tank. My car will need a top up at 4hrs... But they are on 1600cc engines, and have a MPG of more than some luxury road cars get around town, ... as in 1.5km per litre in the metrics, I think it works out more than 5 mile per gallon?. And what is the world record for hyper-mileing?.. en.wikipedia.org/wiki/Shell_Eco-marathonThey hold that competition every year now, and its astounding how much they can do. But in "mortal" terms, unmodified road car, the current world record is set by a diesel WV passat that was averaging something like 97 Miles per [uk] gallon. [source Guinness world records...] And they also broke other world records as well, such as the world longest tailback behind them [/sarcasm...] [1] Question, in UK, we go "Round numbers", speed limits are 30/40/50/national speed limit 60 and motorway 70. Why is it that the Americans do it 25/35/45/55 etc?. |

Two sides of the same story.
If your vehicle is designed as a town runabout, its probably got no aerodynamics, designed to sit in traffic at less than 30 most of the time, why the need for aero.
If vehicle [x] is designed as a Rep-Mobile, mile muncher, designed to get from one city to another economically as it can but spend most of its life at highways speeds above 40/50, it will have aero, because it needs it.
In this way, I am arguing the same point as you, but differently, in that all vehicles are designed to have different Coefficient of Drag, dependant on use.
Your average motorway able distance covering car is designed to carry 4/5 people and luggage from A to Z as efficiently as possible...
The G-Wiz is designed to do short trips from A to A.5 just about faster than walking at the cost of a daily newspaper per week.
The trailer I passed carrying 8 Jags down the highway behind a cab-over flat fronted truck is as aerodynamic as a brick but will get 8 vehicles from A to Z with less fuel that driving all 8 vehicles independently, because the ton per mile per gallon of fuel has eliminated aero, as the average speed of that truck is less than aero can help... or should I say could help, modern designs are making some trucks more aerodynamic as modern technology can allow this.
I am therefore stating that on average, 55 is bunkum, because some vehicles are designed to be more efficient faster than that, and some are not designed to be at that speed or above in the first place.
This is a vehicle by vehicle test, no two vehicles will be exactly the same?. Unless its just a re-badged Toyota that has Subaru badges and parts, the Toyota/Subaru GT86 thing they use now on top gear star in a reasonably fast car.
That looks confusing...
On UK roads, look at the side streets, if they dont have speed limits posted on the corners, presume 30 limit in place, 40 where signed and side streets have the 30 limits posted, 50 on dual carriageways, 60 where posted or de-restricted, 70 only on motorways or A-road/M, 20 in highly residential areas, but you would have to pass through a 30 limit to get to a 20, most of the time, except side streets well signed of a 40 limit bypass.
How you manage with all those different limits is probably cultural difference, if you are used to that, you probably manage quite well.
And heavy goods are limited to 10mph below the posted limit above 30 mph, and have limiters to prevent anything over 55(ish)

Here in Germany, speed limits are just for safety only. There are 3 basic speed limits which don't need signs:
1. Inside a locality: 50kph (30mph). Also you are not allowed to use your high beams.
(locality limits are marked by big yellow rectangular signs with the name of the city)
2. Outside a locality: 100kph (60mph)
3. If oncoming traffic is separated by a barrier, there is no speed limit if there is no sign. You can go as fast as is safe. What is safe depends on your vehicle, road conditions and weather. Above 130kph, you have extra responsibility to prevent damage and injury.
Vehicles above 7.49 tons or with more than 2 axles (e.g. trailer) are limited to 80kph at maximum although some vehicles can have a permit for 100kph and must be marked.
It is encouraged to keep your speed below 130kph to save stress and fuel but you don't need to if there is no official speed limit. In my areas, most parts of the Autobahn are limited to 80/100/120 kph which had reduced the amount of deadly car accidents beneath 10%. The only environmental speed limits are special limits (usually 80kph) at night meant for noise reduction in residential areas. Autobahn sections without a speed limit can be heard over many miles. A car going 100kph is about twice as loud as a car going 80.
There is no exact number where something "goes click" and makes a lot of a difference. The faster you displace air, the more fuel you need to travel the same distance. The internal combustion engine has a problem, throttling it means a significant loss in efficiency. If you drive too slow, you waste gas by throttling your engine by too much. If you drive too fast, you waste gas by displacing the air too hard.
So the best efficiency you get by using a tiny engine which makes the car barely move when not throttled so you don't waste gas displacing the air nor throttling the engine. But this is impractical.
The bigger your engine, the more fuel you waste by driving too slow. But you are wasting fuel anyway by owning an engine which is big. This is the whole excuse of the existing of the Smart Car. It is highly efficient driving within city limits, stop&go and crawling the rush hour. And it is very good at doing it, it is as comfortable as any other car else. Driving between cities is totally different. The Smart is not comfortable, not that economic any more and it will wear down quickly. Exceeding 120k miles is the holy grail. But "normal" cars can't exceed this mileage either when always stuck in dense city traffic.
Personally I feel like not going anywhere at just 55 mph (e.g. pulling a trailer which restricts me to 80 kph), I think driving cross country on endless straight roads in the US would turn me insane. I feel OK going 70kph as is the usual speed limit on twisty roads. But on perfectly straight roads, I feel very uncomfortable at below 130 kph...

I was doing field service work when the 55 limit went into effect, driving about 70,000 miles per year and getting paid for my drive time. Still, the 55 limit was devastating on long distance trips. Fortunately, it wasn't enforced much after the first year or so except in locally small areas, and thanks to CB radio, tickets were relatively easy to avoid. |
