SUV

A sport utility vehicle (SUV) is a generic marketing term for a vehicle similar to a station wagon, but built on a light-truck chassis. It is usually equipped with four-wheel drive for on- or off-road ability, and with some pretension or ability to be used as an off-road vehicle. Not all Four wheel drive vehicles are termed as SUV. Some SUVs include the towing capacity of a pickup truck with the passenger-carrying space of a minivan or large sedan. Since SUVs are considered light trucks and often share the same platform with pick-up trucks, they are regulated less strictly than passenger cars under the two laws in the United States, the Energy Policy and Conservation Act for fuel economy, and the Clean Air Act for emissions.
The term is not used in all countries, and outside North America the terms "off-road vehicle", "four-wheel drive" or "four-by-four" (abbreviated to "4WD" or "4x4") or simply use of the brand name to describe the vehicle like "Jeep" or "Land Rover" are more common. However, not all SUVs have four-wheel drive capabilities. Conversely, not all four-wheel-drive passenger vehicles are SUVs. Off-road vehicle is a broad class of vehicles, built primarily for off-road use. However, this distinction is often not made by the general public and the media. Although some SUVs have off-road capabilities, they often play only a secondary role, and SUVs often do not have the ability to switch among two-wheel and four-wheel-drive high gearing and four-wheel-drive low gearing. While auto makers tout an SUV's off-road prowess with advertising and naming, the daily use of SUVs is largely on paved roads and in urban areas.
Extremely popular in the late 1990s and early 2000s, the SUV's popularity has since declined. Due to high oil prices and a declining economy since the mid-2000s, manufacturers have responded to buyers' complaints[citation needed]. The traditional truck-based SUV is gradually being supplanted by the crossover SUV, which uses an automobile platform for lighter weight and better fuel efficiency, as a response to much of the criticism of sport utility vehicles.


Popularity
SUVs became popular in the United States, Canada, and Australia in the 1990s and early 2000s. U.S. automakers could enjoy profit margins of $10,000 per SUV, while losing a few hundred dollars on a compact car. For example, the Ford Excursion could net the company $18,000, while they could not break even with the Ford Focus unless the buyer chose options, leading Detroit's big three automakers to focus on SUVs over small cars.
Small cars were sold mainly to attract young buyers with inexpensive options and to increase their fleet average fuel economies to meet federal standards. The relatively high wages of unionized auto workers in the U.S. and Canada (members of the UAW and CAW, respectively), compared to the low wages of non-union workers at non-U.S. companies like Toyota, made it unprofitable for the U.S. auto makers to build small cars. For example, the General Motors factory in Arlington, Texas where rear-wheel drive cars were built, such as the Chevrolet Caprice, Buick Roadmaster, and Cadillac Fleetwood Brougham was converted to truck and SUV production, putting an end to full-size family station wagon and overall terminating production of rear-wheel drive full-size cars. Due to the shift in the Big Three's strategy, many long-running cars like the Ford Taurus, Buick Century and Pontiac Grand Prix fell behind their Japanese competitors in features and image (relying more on fleet sales instead of retail and/or heavy incentive discounts); some were discontinued.
Buyers were drawn to SUVs' large cabins, higher ride height, and perceived safety. Full-size SUVs often offered features such as three-row seating, to effectively replace full-size station wagons and minivans. Wagons were seen as old-fashioned. Additionally, full-size SUVs have greater towing capabilities than conventional cars, and can haul trailers, travel trailers (caravans) and boats. Increased ground clearance is useful in climates with heavy snowfall. The very low oil prices of the 1990s helped to keep down running costs. The SUV's image of utility may partly explain its popularity, not least among some women, who constitute more than half of all SUV drivers. SUV was one of the most popular choices of vehicle for female drivers in the U.S.


Use in remote areas
SUVs are often driven in places such as the Australian Outback, Africa, the Middle East, Alaska, northern Canada, western United States, Iceland, South America, and parts of Asia which have limited paved roads and require a vehicle to have all-terrain handling, increased range, and storage capacity. The scarcity of spare parts and the need to carry out repairs quickly resulted in the popularity of vehicles with the bare minimum of electric and hydraulic systems, such as the basic versions of the Land Rover, Jeep Wrangler, and Toyota Land Cruiser. SUVs for urban driving have traditionally been developed from their more rugged all-terrain counterparts. For example, the Hummer H1 was developed from the HMMWV, originally developed for the military of the United States.
As many SUV owners never used the off-road capabilities of their vehicle, newer SUVs (including crossovers) now have lower ground clearance and suspension designed primarily for paved roads.
SUVs are also chosen by some buyers as they have more interior space than sedans of similar sizes. In areas with gravel roads in summer and snow and ice in winter, four-wheel drives offer a safety advanatge due to their traction advantages under these conditions.
The sport utility vehicles have also gained popularity in some areas of Mexico, specially where there is desert or in cities where drivers easily find potholes, detours, high water and rough roads. Their increasing use is also due to the fact that when traveling out of major populations, a high number of roads are dirt, washboard and mud in the rainy seasons.


Luxury SUV
Numerous luxury vehicles in the form of SUVs and pickup trucks are being produced. Luxury SUV is principally a marketing term to sell fancier vehicles which may have higher performance, comfort, technology, or brand image. The term lacks both measurability and verifiability, and it is applied to a broad range of SUV sizes and types.
Nevertheless, the marketing category was created in 1966 with Kaiser Jeep's luxurious Super Wagoneer. It was the first SUV to offer a V8 engine, automatic transmission, and luxury car trim and equipment in a serious off-road model. It came with bucket seating, air conditioning, sun roof, and even a vinyl roof. Land Rover followed suit in 1970 by releasing the Range Rover. The trend continued with other competitors adding comfort features to their rudimentary and truck-based models.
The production of luxury models increased in the late 1990s as they generated higher profit margins than ordinary automobiles did. For some auto makers, luxury SUVs were the first SUV models they produced. Some of these models are not traditional SUVs based on light truck as they are classified as crossovers.
Luxury SUVs are proving to be popular in India[citation needed] where the road infrastructure is often poor even in big cities. The expensive luxury cars have low ground clearance which results in the scraping of the car in broken sections of roads and speed breakers. Models like the Audi Q7 and BMW X5 often sell more than the sibling models. Another example is the Volvo XC90, which has sold almost twice their other model offered in India, the S80.
The luxury SUV class encompasses both smaller 5 passenger SUVs and larger 7 passenger SUVs. All of them provide luxurious amenities and cutting edge technology. These features can be found not only in the inside of the cabin but also in the outside. People who look for a luxury vehicle that offers more cargo capacity than a sedan can prefer a luxury SUV class. This is also a vehicle aimed for those who prefer an SUV with a little more style.
Luxury SUVs typically offer the most expected safety features including side airbags, ABS and traction control, and many of them also come with electronic stability control, crash resistant door pillars, dynamic head restraints and back-up sensing systems.
The U.S. News and World Report Rankings and Reviews ranks premium midsize SUVs and crossovers based on an in-depth analysis by its editors of published auto ratings, reviews and test drives. Ranking is based on the score on performance, exterior, interior, safety, and reliability obtained by the vehicles. Currently the 2010 Acura MDX appears in the first place followed by the 2010 Lexus RX 350.


Designs
Although designs vary, SUVs have historically been mid-size passenger vehicles with a body-on-frame chassis similar to that found on light trucks. Early SUVs were mostly two door models, and were available with removable tops. However, with market and regulatory forces pushing the SUV market towards four doors, by 1999 all full-size two door SUVs were gone from the market. As of 2011, only the Jeep Wrangler remains as a two door SUV, although Jeep also offers a four door variant. Since the mid 90s, the two door SUV market was cannabalized by the four door SUV. Two door SUVs were mostly carry-over models, and they were not viewed as viable enough to redesign at the end of their design cycle. They generally were not promoted heavily during this time, leading to even hardcore off-roaders purchasing four door models. The 2-door SUV would return to impact for the 2010s with the release of the Range Rover Evoque and the Nissan Murano convertible, although both vehicles are still considered unibody.
Most SUVs are designed with an engine compartment, a combined passenger and cargo compartment, and no dedicated trunk such as in a station wagon body. Most mid-size and full-size SUVs have three rows of seats with a cargo area directly behind the last row of seats.
SUVs are known for high ground clearance, upright, boxy body, and high H-point. This can make them more likely to roll over due to their high center of gravity. Bodies of SUVs have recently become more aerodynamic, but the sheer size and weight keeps their fuel economy poor.


History
Early SUVs were descendants from commercial and military vehicles such as the World War II Jeep and Land Rover. SUVs have been popular for many years with rural buyers due to their off-road capabilities.
The earliest examples of longer-wheelbase wagon-type SUVs were the Chevrolet Carryall Suburban (1935), GAZ-61 (1938), Willys Jeep Wagon (1948), Pobeda M-72 (GAZ-M20/1955), which Russian references credit as possibly being the first modern SUV, International Harvester Travelall (1953), Land Rover Series II 109 (1958), and the International Harvester Scout 80 (1961). These were followed by the more 'modern' Jeep Wagoneer (1963), International Harvester Scout II (1971), Ford Bronco (1966), Toyota Land Cruiser FJ-55 (1968), the Chevrolet Blazer / GMC Jimmy (1969), and the Land Rover Range Rover (1970).
According to the transportation curator at the Henry Ford Museum, Robert Casey, the Jeep Cherokee (XJ) was the first true sport utility vehicle in the modern understanding of the term. Marketed to urban families as a substitute for a traditional car, the Chrerokee had four-wheel drive in a more manageable size (compared to the full-size Wagoneer), as well as a plush interior resembling a station wagon. With the introduction of more luxurious models and a much more powerful 4-liter engine, sales of the Cherokee increased even higher as the price of gasoline fell, and the term "sport utility vehicle" began to be used in the national press for the first time.
