hypermiling

Hypermiling has come under fire from several sides because some hypermilers show dangerous or illegal behaviour,{{cite web|url=http://www.smh.com.au/news/national/motorists-risking-their-lives/2008/08/23/1219262622708.html |title=Motorists risking their lives to save on petrol |publisher=Smh.com.au |date=2008-08-23 |accessdate=2011-05-28}} such as tailgating larger vehicles on motorways to save fuel, cycling between accelerating and coasting in neutral, and even turning the engine off when its power is not needed.{{cite web |last=CNET|title=How To: Hypermile and get great gas mileage|website=YouTube |date=2014-11-11|url=https://www.youtube.com/watch?v=XsCt_bFvXeg |archive-url=https://ghostarchive.org/varchive/youtube/20211221/XsCt_bFvXeg |archive-date=2021-12-21 |url-status=live|access-date=2018-11-12}}{{cbignore}} For this reason, the Hypermiling Safety Foundation was established in August 2008 to promote a safety and education program that promotes legal fuel-saving techniques.

There are various techniques used by gas-powered car driving hypermilers that help increase their gas mileage.

Techniques that can be used to minimize fuel consumption while driving include:{{Cite journal |last=Momčilović |first=Vladimir |last2=Dimitrijević |first2=Branka |last3=Stokić |first3=Marko |date=25 May 2017 |title=Eco-Driving -- Potentials and Opportunities Within Green Logisitics |url=https://logic.sf.bg.ac.rs/wp-content/uploads/LOGIC_2017_ID_37.pdf |journal=LOGIC}}{{Cite web |title=What is hypermiling and how do you do it? |url=https://www.autoexpress.co.uk/car-news/104466/what-is-hypermiling-and-how-do-you-do-it |access-date=2025-05-30 |website=Auto Express |language=en}}

• Avoiding unnecessary braking and acceleration
• Maintain a lower, steady speed in the highest gear at a low RPM
• Shift up gears as early as possible
• Avoid idling
• Utilizing cruise control
• Use air conditioning and electric equipment sparingly
• Keep windows closed to reduce drag
• Choosing parking locations based on the weather (parking in the sun in cold weather to keep the car warm, or parking in the shade in warm weather to keep the car cool so the air conditioner is not needed)
• Parking "face out" to drive forwards immediately after parking
• Parking on a downwards slope to coast forward
• Anticipate driving maneuvers rather than reacting to what happens directly ahead of the car
• Practice the Driving Without Brakes (DWB) mantra, where you try and drive for as long as possible without touching the brakes

Techniques that can be used to minimize fuel consumption before driving include:

• Planning to avoid traffic congestion
• Monitoring energy efficient tires and inflation using TPMS (tire pressure monitoring system)
• Adjusting aerodynamic devices
• Avoid overfilling the fuel tank
• Keep up on proper and timely car maintenance
• Choose to drive a fuel-saving hybrid car, like a Toyota Prius
• Choose to walk or cycle instead of driving for shorter distances
• Plan a route needing the least amount of acceleration and braking

Carrying the least amount of weight possible will also aid in less fuel consumed. Things like golf clubs, tool boxes, strollers etc. can add unnecessary weight to the vehicle.{{Cite web |title=Hypermiling Techniques |url=https://www.hypermiler.co.uk/hypermiling/hypermiling-techniques |access-date=2023-11-01 |website=Hypermiler.co.uk |language=en-US}} Even wearing thin-soled shoes can aid in reducing fuel consumption; thinner soles can result in increased sensitivity to the gas pedal.

Hypermiling can also be practiced using relatively lower fuel efficiency vehicles like SUVs. An Edmunds experiment reports that hyperm­iling could add 35.4% more miles per gallon from a Land Rover LR3, which usually gets {{cvt|12|mpgus}} in the city and {{cvt|17|mpgus}} on the highway.

Drafting as a technique for hypermiling has been a subject to controversy. This involves driving close to or slipstreaming behind the car in front, potentially saving 40% of fuel. Drafting can save energy by using the car ahead to push air out of the way. This technique is subject to controversy due to the reduction in visibility and the risk of not being able to brake fast enough if the car in front stops.{{Cite web |title=Gale - Product Login |url=https://galeapps.gale.com/apps/auth?userGroupName=byuprovo&origURL=https%3A%2F%2Fgo.gale.com%2Fps%2Fretrieve.do%3FtabID%3DT004%26resultListType%3DRESULT_LIST%26searchResultsType%3DSingleTab%26retrievalId%3D95062f9e-0005-4d61-b64a-90898ab60b3e%26hitCount%3D1%26searchType%3DAdvancedSearchForm%26currentPosition%3D1%26docId%3DGALE%257CA492201442%26docType%3DBrief%2Barticle%26sort%3DRELEVANCE%26contentSegment%3DZNEW-FullText%26prodId%3DSTND%26pageNum%3D1%26contentSet%3DGALE%257CA492201442%26searchId%3DR1%26userGroupName%3Dbyuprovo%26inPS%3Dtrue&prodId=STND |access-date=2023-11-01 |website=galeapps.gale.com}}

The range of electric cars is limited. To get the most out of the battery, drivers sometimes use hypermiling techniques.[https://www.treehugger.com/cars/you-can-get-over-range-anxiety-oscar-helps.html What's Electric Vehicle Hypermiling?] Some aim to set a record for most mileage from a single charge. For example, a Tesla Model 3 ran more than 1000 km with one battery charge. The average speed was 38 km/h and the whole drive took around 30 hours. The tester used the autopilot of Tesla Model 3, running the car unmanned. The test car did not drive on a public road.[https://electrek.co/2018/07/16/tesla-model-3-autopilot-unmanned-hypermiling-record/ Tesla Model 3 unmanned on Autopilot travels 1,000 km on a single charge in new hypermiling record]

There have been several aircraft hypermiling competitions held throughout the years, such the FuelVenture and CAFE challenges.{{Cite web |url=http://www.cafefoundation.org/ |title=CAFE Foundation Website |access-date=2019-06-05 |archive-date=2022-04-26 |archive-url=https://web.archive.org/web/20220426033658/http://www.cafefoundation.org/ |url-status=dead }} Klaus Savier won the 2009 Fuelventure 400 in a VariEze aircraft which got {{cvt|45|mpgus}} at {{cvt|207|mph}} with a modified Continental O-200 engine upgraded with a computerized fuel injection and ignition system by Light Speed Engineering.[http://www.lightspeed-aero.com/ Light Speed Engineering] By slowing to extend range, mileage approaches {{cvt|100|mpgus}}.{{cite magazine |last=Wired|title=45MPG at 207MPH|magazine=Wired |date=2009-11-02|url=https://www.wired.com/2009/11/45mpg-at-207mph/|access-date=2019-06-03}}

In World War II the famed pilot Charles Lindbergh consulted with pilots of the Army Air Corps and the Marine Corps and introduced engine-leaning techniques which greatly improved fuel consumption at cruise speeds and enabled aircraft to fly longer-range missions.

On June 2008 at the Michigan International Speedway, Dale Earnhardt Jr. won the Lifelock 400 and shared information about coasting (a hypermiling technique) behind the pace car during the caution flag.

In August 2017, the official Tesla club in Italy, Tesla Owners Club Italia, had five people drive 29 hours in Southern Italty to drive a Tesla Model S 100D a total of {{cvt|1078|km}} on a single charge.{{Cite web |last=Liptak |first=Andrew |date=2017-08-06 |title=Italian Tesla drivers set distance record after driving Model S 670 miles on a single charge |url=https://www.theverge.com/2017/8/6/16104628/tesla-drivers-italy-distance-record-model-s |access-date=2025-05-30 |website=The Verge |language=en-US}}

In May 2018, two Colorado residents drove 32 consecutive hours to drive their Tesla Model 3 {{cvt|606.2|miles}} on a single charge. It beat a previous record of 560 miles from a Tesla Model S P100D, but it fell slightly short of a 670-mile run in a Model S by an Italian team last August.{{Cite web |last=Hawkins |first=Andrew J. |date=2018-05-29 |title=Tesla Model 3 drives 606 miles on a single charge in hypermiling record |url=https://www.theverge.com/2018/5/29/17405906/tesla-model-3-hypermilling-driving-record |access-date=2025-05-30 |website=The Verge |language=en-US}}

In 2018, Frenchman Pierre Desjardins set a record covering {{cvt|351|miles}} of the Périphérique ring road in Paris on a single charge in a 40kWh Renault Zoe, which had an official WLTP range of just {{cvt|186|miles}}, and ended up with a fuel efficiency of 7.9 miles per kilowatt hour.

In 2022, a team from the armed-forces charity Mission Motorsport drove two stock 52kWh Renault Zoe cars, with an official range of 245 miles, at Thruxton Circuit in Hampshire to break the previous Renault Zoe EV hypermiling record. They maintained a speed of 19-23 mph, and followed racing lines that offered the path of least resistance. The first car finished at 424.7 miles, while the second car finished at 475.4 miles, which was 230.4 miles more than the Zoe’s WLTP range and ended up at 9.14 miles per kilowatt hour.

As of 2022, hypermiling may be considered a popular pastime, where there are MPG marathon events and hypermilers share their success in maximizing fuel efficiencies.
