- While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly speeds above 55 miles per hour. Just slowing down from 65 mph to 55 mph can increase your miles per gallon by as much as 15 percent. According to the U.S. Department of Energy (DOE), as a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.21 per gallon for gas (at $3.00 per gallon). So, the Fuel Economy Benefit of driving slower is between 7 and 23 percent. The equivalent gasoline savings is $0.21 to $0.71 per gallon. Let's take two hypothetical drivers, Bill and Bob.

- On average, a truck traveling at 65 mph instead of 75 mph will experience up to 27-percent improvement in fuel consumption. As a rule of thumb, for every one mile per hour increase in speed, there is a corresponding 0.14 mile-per-gallon (mpg) fuel consumption penalty, says Kedzie.

Speed Kills MPG MPG For Speed .com. Unfortunately, it's true. Your car's gas mileage decreases once it gets past its optimal speed. For most cars, this is around 55-60 mph. This means that every time you go over this speed, you're essentially wasting gas and money - and creating unnecessary greenhouse gases.

Speed limits in the United States Highway speed limits can range from an urban low of 35 mph (56 km/h) to a rural high of 85 mph (137 km/h). Speed limits are typically posted in increments of five miles per hour (8 km/h). Some states have lower limits for trucks and at night, and occasionally there are minimum speed limits.

Speed Speed limits have traditionally been the responsibility of the states. In the mid-1970s, however, Congress established a national maximum speed limit by withholding highway funds from states that maintained speed limits greater than 55 mph. The requirement was loosened for rural interstates in 1987 and completely repealed in 1995.

- Rural and City Drivinq. In cities, towns, and villages the maximum speed is 50 km/h, unless otherwise posted. Outside cities and villages the maximum speed is 100 km/h. The speed limits vary on post but never exceed 50 km/h or 15 km/h if passing troops. Seatbelts are required for all occupants. Children four years old or younger who do not exceed 50 lbs must use a U.S. or GE.

- When you see the yellow speed signs under curve signs, that's the maximum rated safe speed for that particular stretch. IOW, when you see a curve sign with a 45mph sign directly under it, you'll be able to safely make the curve under normal driving conditions as long as you are going 45 mph or less.

Speed limit The speed limit is commonly set at or below the 85th percentile operating speed (being the speed which no more than 15% of traffic is exceeding) and in the US is typically set 8 to 12 mph (13 to 19 km/h) below that speed.

Speed Maximum Speed Limit. The maximum speed limit on most California highways is 65 mph. You may drive 70 mph where posted. Unless otherwise posted, the maximum speed limit is 55 mph on two-lane undivided highways and for vehicles towing trailers. Other speed limit signs are posted for the type of roads and traffic in each area. All speed limits are based on ideal driving conditions. Construction zones usually have reduced speed zones.

- Discussion in 'Fuel Economy' started by Sol, Jan 25, 2009. Sol Member. I'm driving a Nissan Latio(Singapore version of the versa) with 4AT. I've been looking for the specific speed at which torque converter lockup occurs, but with no success. The Versa manual states 86-94km/h, but I'm not sure if that's for Versa only, or it applies to Latio as well. I'm a bit reluctant to go above 90km/h too(speeds here aren't as crazy as in the States.)

Speed limits Speed limits. You must not drive faster than the speed limit for the type of road and your type of vehicle. The speed limit is the absolute maximum - it doesn’t mean it’s safe to drive at this speed in all conditions. A speed limit of 30 miles per hour (mph) or 48 kilometres per hour (km/h) usually applies, unless you see signs showing otherwise.

Diesel Economics & Fuel EconomyUpdated March 26, 2013 Speed is more critical on a diesel than a gas engine. On the highway, in the 50-75 mph range, the fuel economy will go down about 3 mpg for each 10 mph increase in speed. A gasoline engine will lose about 1-1/2 mpg for each 10 mph increase in speed.

Top 5 Fuel Efficient Trucks That Still Get the Job Done Fuel Economy: 20 mpg city/23 mpg highway. We recommend the gas/electric Silverado Hybrid for fuel-conscious folks who plan to do a lot of driving in the city, because that's where it shines. Twenty mpg in urban driving is quite simply unheard of for a full-size truck, especially one with 332 hp (379 hp with electric assist) and 367 lb-ft of torque. On the downside, the complicated transmission is sometimes slow to respond, and the price is high.

Sydney The Texas State Transportation code § 545.352 defines lawful for speeds for various types of roads. Inside a city or town, 30 miles per hour is assumed to be a safe and lawful speed, unless you are driving in an alleyway. Then, the speed limit is 25 miles per hour. Once you get onto a numbered highway and away from urban and residential areas, the speed limit jumps to 70 miles per hour. On an unnumbered highway outside of an urban district, the speed limit is usually 60 miles per hour.

A Simple Explanation of Tire Speed Rating Speeding through the years. When the speed rating system was developed, the Unlimited V category of over 210 km/h (130 mph) was the top speed rating possible. As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety.

Canada Speed Limits in Kilometers and Miles per Hour 40 – 50 kph. 25 - 30 mph. School zones. 30 - 50 kph. 20 - 30 mph. Speed limits in Canada are measured in kilometers per hour (km / h) and usually marked by signs on the side of the road. When the speed limit is not marked, drivers should keep to the provincially set speed limits which fall within the limits as outlined in the Speed Limits in Canada Table (above). Check at the Canada border or rental car office for local speed limits and other road regulations. Also read our Driving in Canada Guide.
