• No not always.
  • Nope. It is in case you enhance your engine to make it more powerful.
  • No not really thats why there is usualy a red line after a certain number (usualy 130) its how fast before the engine blows. Not sure if its the same on all cars.
  • GO try it from 0 to 180 then come back and let us know what happens,,,,,,lol
  • Wheeeeeeeeeeeeeeee Booooom O0ps i think i broke it lol +5
  • I should hope not. I have had a few new cars in my time and not one of them ever came near the speed the Speedometer said we could go too.
  • No. It's either there to make you think you have a fast car, or else it's a speedometer that can be fitted on a variety of cars including those that can reach 180.
  • No, but did you know that the F on the fuel guage means full but the E means Enough so keep driving
  • Depending on the car usually faster than the speedometer reads. +5
  • No. Most cars manufactured in the last 10 years (or more) are governed to limit the speed to around 115, unless they are production hotrods. On the flip side, I have a truck who's speedometer only goes to 85... GPS says something different (see upper right corner) This required heavy modification and Z rated tires to pull off. 180 would be ridiculously dangerous.
  • 1) If you drop your car from a plane in free fall, it can certainly go quicker. Also, if you are on a long, steep slope downwards, with tailwind, you would possibly be able to reach a higher speed. In normal driving conditions, it would not make much sense to reach the maximum of the speedometer display, because you could not exactly know how quick you are, so this will probably never happen. Another issue is how accurate the display of the speedometer is. 2) "I was sitting with a maruti engineer last evening and he said "yes you can reach the maximum speeds given on your speedo, all you need is a clean straight strech." " "It differs from different car eg the audi a4 can reach the end of the speedo it given a streach where as the Fabia with 220kmph is funny it can hardly reach 150kmph , they have kept the european speedomater in fabia but there they have more powerful engines ,my zen has 160kmph were as I have managed 140kmph it won't go more faster than that." "I touched 130kph on our Indigo LS (May 2004)and would have crossed 150kph if the Bike Rider would have not come across. I did not get chance to try after that event. I crossed 180kph on Indigo XL Grand DiCOR on Pune-Mumbai Expressway. In fact I wanted to try more, but was restricted by the Tyres' Speed Rating. The Speed Rating for 175/65R14 Tubeless is "T" (Which means Max. Speed allowed is 190kph). So I did not try more than 180kph (Speedo Indicated)." Source and further information: 3) "Most speedometers have tolerances of some 10% plus or minus due to wear on tires as it occurs. Additional sources of error are tire diameter variations due to temperature, pressure, vehicle load, and nominal tire size. Modern speedometers are said to be accurate within 10% but as this is legislated accuracy, this may not be entirely correct. This can make it difficult to accurately stay on the speed limits imposed; most countries allow for this known variance when using RADAR to measure speed, although levels of some 3 km/h or 3% are also used in areas of tough enforcement. This causes many arguments due to motorists complaining that they were not doing the speed as reported. " "European Union member states must also grant type approval to vehicles meeting similar EU standards. The ones covering speedometers are similar to the UNECE regulation in that they specify that: - The indicated speed must never be less than the actual speed, i.e. it should not be possible to inadvertently speed because of an incorrect speedometer reading. - The indicated speed must not be more than 110 percent of the true speed plus 4 km/h at specified test speeds. For example, at 80 km/h, the indicated speed must be no more than 92 km/h." "As of 1997, Federal standards in the United States allowed a maximum 5% error on speedometer readings (per "Auto Tutor", American Automobile Association of California magazine, Oct. 17, 1997). Aftermarket modifications, such as different tire and wheel sizes or different differential gearing, can cause speedometer inaccuracy." Source and further information:
  • Only way you'll know for sure is to try it. +5
  • NOPE not all. I have a truck that tops out at 83 ungoverned but the speedometer goes up to 100. I have a supped up Dodge that will only read up to 120 but I have had it lazared at 139 on a closed track. Depends on weather, engine, road, gears, tires, ECU settings.
  • No, and I'd advise against trying. Your tires probably aren't rated for that speed and above a speed much lower than 180 any little bump in the road can flip your car. (I saw a TV program about the German autobahn, and they showed what slight defects in the road can do to overly fast cars.)
  • No, speedometers are somewhat standardized.
  • no, only the speedo can go there, the car will catch up later.
  • For the most part no. But just in case, should I stay off the road for a while? Look for flaming asphalt? Be wary of dust clouds moving down the highway?
  • Not necessarily.
  • really high-end cars might, but most today will cut-off at 90 or 95.
  • maybe if it is bmw, or a caddy. the car might run out of fuel by the time it hits 180.
  • no nost cars 1990 or later are computer limited to 155 mph unless it's a vette ot a viper
  • CaRbOn, you mean you haven't tried this out? LOL. Nah, it doesn't work and I wonder why they bother to go that high.
