维基百科原文

A dune buggy is a recreational vehicle with large wheels, and wide tires, designed for use on sand dunes or beaches. The design is usually a modified vehicle with a modified engine mounted on an open chassis.The modifications usually attempt to increase the power to weight ratioby either lightening the vehicle or increasing engine power or both.Those with an open frame chassis are called sandrails.
  A similar, more recent generation of off roadvehicle, often similar in appearance to a sand rail but designed fordifferent use, is the "off road go kart". The difference between a dunebuggy or go kart and an off road buggy or kart is sometimes nothingmore than the type of tires fitted — sand tires or all terrain tires.
  沙地车是一种配有大轮子款轮胎的休闲车辆,主要适合在沙丘地带或者沙滩行驶。沙漠车一般是用别的车子改装过来的,同样改装过的引擎装在敞开的车架上。改装要么是减轻车身重量,要么是提高引擎功率,目的都是加大功率和车重的比率。这种配有敞开车架的车子一般被称作钢管车。
同一类的越野车最新款式在外观上和沙漠车很接近,但是用途不一样,一般被称作卡丁车。沙地车,卡丁车和越野卡丁车的主要区别就是使用的轮胎不一样-也就是是沙漠胎和全地形胎的差别。
  
Design设计
Dune buggies are usually created using one of two to three different methods.
The first involves alteration of an existing vehicle, most notably the older Volkswagen Type One (Beetle, or Bug). The Beetle is preferred for a variety of reasons. Most significant is the position of the rear mounted Volkswagen engine,which with removal of bodywork transfers a high proportion of theweight to the rear driven wheels for extra traction. The engine is aircooled, simplifying engine modification, and the absence of a radiatoreliminates a source of failure. The low price; robustness of the frontsuspension; and the sizable quantity of spare parts from other VWBeetles and Type 2 buses are a further advantage. Corvairengines are also a popular way to upgrade to 6 cylinders and sometimesvehicles are fitted with turbochargers to provide as much as 180horsepower (130 kW). For example, one such conversion was a 1970 Manx 2on a 1961 VW chassis. It was fitted with a 180 hp (130 kW) turbochargedCorvair engine, with reverse rotation, mated to a VW transaxle.
The second method involves construction of avehicle frame from steel tubing formed and welded together. Theadvantage of this method is that the fabricator can change fundamentalparts of the vehicle (usually the suspension and addition of a built-inroll cage). Buggies of this type are called sandrailsbecause of the rail frame. Sandrails, as with the VW Bug, often havethe engine located behind the driver. Sizes can vary from a smallengined one seat size to 4 seat, 8+ cylinder vehicles. Sandrails canhave panels or custom shaped body coverings over the rails and tubingthat comprise the vehicle, though many are left bare.
The third is only a temporary fix. These dunebuggies represent mixes of the above two design philosophies, typicallyafter a converted vehicle sustains damage from age, hard use, oraccidents and spare parts are not available or affordable. This type ofcreation is called The Boston-Murphy style.
沙地车的制作一般采用下列方式之一。
第一种方式是对现有车型进行改造,最常见的车型是大众的甲壳虫。作为首选甲壳虫有如下几个优点:最主要的一点甲壳虫的引擎是后置后驱的,这样在把车身覆盖件拿掉以后车身重量后移,增强后轮抓地性能。风冷引擎改装起来更加容易,没有散热器会降低车子出问题的几率。价钱便宜;前悬挂动感十足;大众甲壳虫和Type 2巴士上众多可以通用的配件都是其优势。Corvair引擎也是一项常见的升级成6缸的配置,有的车上还要配涡轮增压,最后可以达到180马力的功率。比如在1961款的甲壳虫地盘上改出来的1970 Manx 2,上面装的就是一台180马力涡轮增压Corvai引擎,反转,配大众的驱动桥。
第二种方式需要用钢管焊接一个车架出来。这种从零做起的方式好处是可以把车上的一些基本的部件换掉(通常是悬架和防滚架)。这种类型的沙地车就是钢管车了,因为车架是钢管做的。钢管车和大众甲壳虫一样,通常都是后置引擎。钢管车的个头小的配小引擎只有一个座位,大的配8缸引擎4个座位。钢管车通常有定做的车身覆盖件,这样看起来更像一辆车,但是不少钢管车都是裸奔的。

Function用途
Initially dune buggies were designed fornavigating desert or beaches (hence the word "dune"). However, dunebuggies have become more diversified in terms of the terrain they canhandle and are being built for more generic off road tasks, such asCORR / SCORE indoor track racing. Some are even built for and used ason-road vehicles. Typically the function is determined before the buggyis created in order to maximize the comfort or abilities of the vehicle.
Although dune buggies can be bought (as a kit),many drivers make their own. This is done by separately buying chassis,engine, tires, steering wheel, and axles. Some builders make their ownchassis, which creates a special, customized vehicle.
A 1961 or later Volkswagen sedan is the preferred donor to create a Dune Buggy. The VWType 2, Type 3 and Type 4 do not make good donor cars, however theengine, transaxle, wheels, and instruments can be used from thesemodels.
  Other parts that can be salvaged from a donor VWfor use in a Dune Buggy include the front axle and suspension, frame,pedal assembly, shock absorbers, seats, battery, fuel tank (1961 orlater), steering column, brakes, instruments and switches, windshieldwiper, horn and emergency flasher unit.
沙地车最初的用途是在沙漠里或者沙滩上开的(因此英文名称才有沙地这个单词)。但是沙地车逐渐演化,针对不同的地形逐渐分化出不同的车型,用途也不再那么专业了,比如CORR和SCORE场地赛等,有些车子甚至也可以在公路上行驶。一般做法是动手之前先确定车子的用途,这样在做的时候就可以针对性的提高车子的舒适性或者是车子的性能。
尽管沙地车市面上有的买,不少人还是喜欢自己做。他们先买来车架,引擎,轮胎,方向盘和驱动轴等。有些资深玩家干脆自己做车架,做出来的车子就是非常独特的限量版了。

Driverless buggy

Some driverless cars have also been made based on a buggy.
一些无人驾驶的车子也是在沙地车的基础上做出来的。

Military buggies军用沙地车
看起来非常威猛的LSV

Because of the obvious advantages a buggy canafford on some terrain, they are also used by the military. The buggiesbuilt for the US military used to be called Desert Patrol Vehicles (DPV) or Fast Attack Vehicles (FAV), yet have changed name to Light Strike Vehicles. They are used by US Navy Seals, SAS, ... The LSVs are built by Chenowth Racing Products Inc.,a San Diego based company. As with most military material, they are notsold outside the government. The newest version is the ALSV or AdvancedLight Strike Vehicle [1]
沙地车在一些地形具有明显的优势,因此颇受军方的青睐。美国大兵定制的沙地车一般被称为沙漠巡航车或者快攻车,后来统一改为闪电战车。这种车的主要用户为美国海豹部队和SAS等...闪电战车在圣地亚哥的一家名为Chenowth工厂生产。和大多数军品一样这些战车不对私人销售。最新款是增强型闪电战车。

Tube framed buggies钢管车
Over time Buggies have been altered to allow maximum recreational use. They are now available in varying sizes.
The most common form of non-racing buggy consistsof a 'tube frame' which is simple to construct and sturdy. If the framebends or breaks it is simple to fix. Steel tubing is preferred to"pipe" as pipe is rolled and welded, tubing is mandrel drawn, making itstronger and with consistent wall thickness.
Engine size varies depending on the suspension,frame strength and performance needs. Engine size has varied from 50 ccfor small light buggies to 7+ liter engines designed for professionalracing. Dune buggies use both automatic or manual transmissions,sometimes based on application and engine power, but often based simplyon personal choice.
慢慢的沙地车逐渐转变成休闲用车,市面上各种型号都买得到。
最常见的非比赛型的沙地车以简单牢固的钢管车架为框架。如果车架弯了或者断了修起来也简单。车架最好用无缝管而不是焊管,因为焊管是钢板卷起来再焊接的,无缝管一般是抽心拔出来的,相对更结实壁厚更均匀。
悬架不同,车架强度不同,需要的性能不一样装的引擎大小也不一样。引擎从轻量级沙地车的50cc到赛车上用的7升以上的都有。沙地车根据用途和引擎的马力会选择自动档或者手动档变速箱,但是选择变速箱没有什么特别的说法,就看个人的喜好了。

Fiberglass dune buggies玻璃钢沙地车
非常小巧秀气的Meyers Manx

Dune buggies with glass-reinforced plastic(fiberglass) bodies come in many shapes and sizes. Many companiesworldwide have attempted to copy the original fiberglass dune buggy,the "Meyers Manx" built by Bruce Meyers. They can be seen on TV shows such as Wonderbug and Speed Buggy. These types of dune buggies are known as "clones".
用玻璃钢作为车身的沙地车外观和车型也很丰富。世界各地有不少公司都在仿制正版的玻璃钢沙地车,Bruce Meyers做的Meyers Manx,在一些电视节目上比如WonderbugSpeed Buggy都能看到。这种仿制出来的沙地车只能被称作克隆。

Humbug



老款Corvette



Mini-T

Model T


Cheetah

Kitcars are a variant that use the dune buggy philosophy of substitutingsignificant amounts of a car with custom parts to resemble production,modified, or prototypecars. For instance: American Fiberglass Product’s “Humbug” has similarfeatures to a classic Corvette, Berry’s “Mini-T” was a nod to the Ford Model T, or BMB Automotive’s “Surviver” is a scaled down version of the Lamborghini Cheetah.

拼装车也是借用沙地车的一个变种,就像做沙地车一样,拼装车也是把车子上原装的部件换成自己订制的,外观则仿制现有的量产车,改装车或者是概念车。比如美国玻璃钢制品共产生产的Humbug就和老款的Corvette相似。Berry的Mini-T和福特的Model T有一腿车业的Surviver就是兰博基尼Cheetah的瘦身版。
