A '''gas-guzzler''', in informal language, is a vehicle that is perceived to consume a lot of [[fuel]]. |
|||
The term originally came into use in the US when congress established Gas Guzzler Tax provisions in the [[Energy Tax Act]] of 1978 to discourage the production and purchase of fuel-inefficient vehicles. The gas guzzler tax had applied only to cars (not trucks) and was collected by the [[IRS]].<ref>http://www.epa.gov/fueleconomy/guzzler/index.htm</ref> Other countries have followed suit and introduced their own version of a gas-guzzler tax such as Canada's "green levy". |
|||
== Reasons for bad fuel economy == |
|||
There are several reasons for bad fuel economy in cars, vans and trucks: |
|||
* Heavy weight: A heavy vehicle requires more [[Work (physics)|work]] to accelerate than a lighter vehicle, requiring more powerful (larger displacement or super/turbo-charged) engine with higher fuel consumption to achieve a similar [[power-to-weight ratio]]. |
|||
* Large [[drag coefficient]]: A less [[Aerodynamics|aerodynamic]] vehicle must deflect a greater volume of air when moving at the same speed than a more aerodynamic one. To overcome this [[Drag (physics)|drag]], a more powerful engine with higher fuel consumption is needed. |
|||
* High frontal area: A high cross sectional area will increase average fuel consumption. |
|||
* Higher Power: A car with an excessively powerful engine will use more fuel. |
|||
* Too small an engine. Microcar with engine below 1 litre have higher fuel consumptions than 1-2 litre engined cars in real world testing<ref>https://www.telegraph.co.uk/motoring/news/11146868/Smallest-cars-worse-for-fuel-economy.html</ref> |
|||
* Non-Daily use specialty vehicles: Some cars are not designed primarily for daily, mainstream use such as commuting but for other purposes in which impact of fuel economy is negligible. For example, a sports car designed for a limited amount of recreational use would have handling and driver satisfaction as a main focus instead of fuel economy. |
|||
== Means to decrease fuel consumption == |
|||
Then there is the reduction of vehicle weight, with a switch to [[monocoque]] construction instead of [[body on frame]] construction and an increased use of lightweight materials, [[aluminium]], [[plastic]]s and high strength [[HSLA steel]]s instead of ordinary mild [[carbon steel]]. |
|||
Gas-guzzlers are not only seeing a scale back in engine size and weight but also in the type of fuel used to power it to prevent environmental damage caused by the use of fossil fuels. The problem with these alternative fuel technologies is that they are either too expensive for widespread use and/or they are scarcely available especially in smaller countries. |
|||
[[Diesel engine|Diesel]] technology is widespread in light trucks, especially in [[Japan]] and [[Europe]]. The bad reputation of diesel fuel and the previously bad quality of the fuel, however, have led to the rarity of such vehicles in the U.S market. The excessive particle emissions of diesel engines have also been cut back with [[Diesel particulate filter|particulate filter]]s, which are offered for most modern diesel engines. |
|||
Fuel-efficient driving habits and vehicle maintenance are easy to change and can have a big impact on fuel consumption. Sudden acceleration and braking, traveling at high speeds, poorly maintained vehicles (frequency of oil changes and brand), and gasoline brands can also impact overall fuel consumption by over 25%.<ref>[http://www.fueleconomy.gov/feg/driveHabits.shtml Tips to improve your Gas Mileage<!-- Bot generated title -->]</ref><ref>[http://www.edmunds.com/reviews/list/top10/103164/article.html Top 10 Tips for Improving Your Fuel Economy<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20070916110718/http://www.edmunds.com/reviews/list/top10/103164/article.html |date=2007-09-16 }}</ref><ref>[http://www.canadiandriver.com/articles/jk/020724.htm CanadianDriver: Auto Tech - How to increase fuel economy<!-- Bot generated title -->]</ref><ref>http://www.nrcan.gc.ca/energy/efficiency/transportation/cars-light-trucks/fuel-efficient-driving-techniques/7507</ref> There are many other way to [http://www.nrcan.gc.ca/energy/efficiency/transportation/cars-light-trucks/driving/7521 reduce your fuel consumption]. |

== Gas guzzler tax == |
|||
{{Main|Gas Guzzler Tax }} |
|||
=== Basics === |
|||
The U.S government introduced the Gas Guzzler Tax as a part of the [[Energy Tax Act]]. The tax was introduced to tax the purchase of inefficient vehicles at the same time that Corporate Average Fuel Economy (CAFE) standards were introduced. The Gas Guzzler Tax applies only to vehicles classified as cars, as opposed to light trucks. Since 1991, cars with a combined fuel economy rating under {{convert|22.5|mpgus|L/100 km mpgimp|1|abbr=on}} have been subject to the tax. Light trucks, which includes virtually all sport-utility vehicles, pickup trucks and vans, are not subject to the tax. |
|||
=== Criticism === |
|||
The primary criticism of the tax is that it does not apply to light trucks. As a result, relatively few vehicles are subject to the tax. When the tax was first introduced, light trucks were viewed as primarily utilitarian work related vehicles. With the shift towards consumer uses for SUVs and pickups, as automakers discontinued the large body-on-frame [[sedans]] and [[station wagons]] long preferred by many Americans to meet the CAFE standards the original rationale for exempting trucks is considered invalid by critics of the current tax law. Many people who once drove these gas guzzlers switched to even less fuel efficient luxury four-door pickup trucks and SUVs that automakers began marketing as soon as the cars subject to the gas guzzler tax were discontinued. |
