Criticism of sport utility vehicles
Encyclopedia
Sport utility vehicles (SUVs), trucks, vans and other large vehicles are often criticized for a variety of environmental and safety-related reasons.
advantages over smaller vehicles. To this, critics note that SUVs is one of the vehicles more likely to roll over, and in some countries are more likely to be involved in a single-car accident and cause harm to other road users. On the other hand, overall, SUVs are safer for their driver than small cars made by the same manufacturer. However, if the analysis is relative to the cost, smaller cars are often safer.
(ESC) to prevent rollovers on flat surfaces, but 95% of rollovers are "tripped" - meaning the vehicle strikes something low, such as a curb or shallow ditch, causing it to tip over.
According to NHTSA data, SUV's and pickups are at a disadvantage in single-vehicle accidents (such as when the driver falls asleep, or loses control swerving around a deer), which comprise 43% of fatal accidents, with more than double the chance of rolling over. This risk relates closely to overall US motor vehicle fatality data, showing that SUVs and pickups generally have a higher fatality rate than cars of the same manufacturer.
The British television Fifth Gear
programme staged a 40 mph (17.9 m/s) crash between a first generation Land Rover Discovery
with a separate chassis and body, and a modern Renault Espace IV with monocoque

. The 1989-98 Discovery offered less driver/passenger protection than that in the 2003 multi-purpose vehicle with unitary construction from Renault.
writing in The New Yorker
magazine that SUVs can affect traffic safety. This height and weight, while potentially giving an advantage to occupants inside the vehicle, may pose a risk to drivers of smaller vehicles in multi-vehicle accidents, particularly side impacts. In 2003 and 2004 in the U.S., passenger cars were involved in 1.65 and 1.58 fatal crashes per 100M miles respectively, compared to 2.14 and 2.05, nearly 30% more, for light trucks (SUVs pick-ups and vans). In 2004, light trucks were involved in fatal two-vehicle crashes with passenger cars (4,765 total, 0.435 per 100M miles) at nearly 3 times the rate as passenger cars (2,422 total, 0.149 per 100M miles). In the same year, light trucks were involved in fatal two-vehicle crashes with motorcycles (869 total, 0.079 per 100M miles) at a nearly 75% greater rate than passenger cars (738 total, 0.045 per 100M miles). The same year, light trucks were involved in fatal two-vehicle crashes with large trucks at a 3.9% greater rate than passenger cars. Fatal crashes between two light trucks occurred at nearly the same (but greater) rate as fatal crashes between two passenger cars.

s, also known as grille guards, brush guards and push bars to vehicles such as 4x4s and SUVs is only legal if pedestrian safe rated plastic bars and grilles are used). Bullbars are often used in Australia and parts of the United States to protect the vehicle from being disabled should it collide with wildlife.
The initial tests of the Ford Excursion
were "horrifying" in its ability to vaulting over the hood of a Ford Taurus
. The big SUV was modified to include a type of blocker bar suggested by the French transportation ministry in 1971, a kind of under-vehicle roll bar designed to keep the large Ford Excursion from rolling over cars that were hit by it. The problem is 'impact incompatibility' where the 'hard points' of the end of chassis rails of SUVs are higher than the 'hard points' of cars causing the SUV to 'override' the engine compartment and crumple zone
of the car. In order to tackle this problem Volvos first SUV/off-roader the XC90 incorporated structures below the front bumper designed to engage lower height car crumple zones, other manufacturers have followed suit.
Depending on design, drivers of some larger vehicles may themselves suffer from poor visibility to the side and the rear. Poor rearward vision has led to many "backover deaths" where vehicles have run over small children when backing out of driveways. The problem of backover deaths has become so widespread that reversing cameras are being installed on some vehicles to improve rearward vision.
While SUVs are often perceived as having inferior rearward vision compared to regular passenger cars, this is not supported by controlled testing which found poor rearward visibility was not limited to any single vehicle class. Australia's NRMA
motoring organisation found that regular passenger cars commonly provided inferior rearward vision compared to SUVs, both because of the prevalence of reversing cameras on modern SUVs and the shape of many popular passenger cars, with their high rear window lines and boots obstructing rearward vision. In NRMA testing, 2 out of 42 SUVs (5%) and 29 out of 163 (18%) regular cars had the worst rating (>15-metre blind spot). Of the vehicles that received a perfect 0-metre blind spot rating, 11 out of 42 (26%) were SUVs and 8 out of 163 (5%) were regular passenger cars. All of the 'perfect score' vehicles had OEM
reversing cameras.
, a psychological consultant to automakers, many consumers feel safer in SUVs simply because their ride height makes "[their passengers] higher and dominate and look down (sic
). That you can look down [on other people] is psychologically a very powerful notion." This and the height and weight of SUVs may lead to consumers' perception of safety.
Gladwell also noted that the SUV popularity is also a sign that people began to shift automobile safety
focus from active to passive, to the point that in the U.S. potential SUV buyers will give up extra 30 ft (9.1 m) of braking distance
because they believe they are helpless to avoid a tractor-trailer hit on any vehicle. The four-wheel drive
option available to SUVs reinforced the passive safety notion. To support Gladwell's argument, he mentioned that automotive engineer David Champion noted that in his previous driving experience with Range Rover
, his vehicle slid across a four-lane road because he did not perceive the slipping that others had experienced. Gladwell concluded that when a driver feels unsafe when driving a vehicle, it makes the vehicle safer. When a driver feels safe when driving, the vehicle becomes less safe.
Stephen Popiel, a vice-president of Millward Brown Goldfarb automotive market-research company, noted that for most automotive consumers safety has to do with the notion that they are not in complete control. Gladwell argued that many of the 'accidents' are not outside driver's control, such as drunk driving, wearing seat belt
s, driver's age and experience, so a vehicle's safety also depends on the driver itself.
released results of a study that indicated that drivers of SUVs were 11% more likely to die in an accident than people in cars. These figures were not driven by vehicle inherent safety alone but indicated perceived increased security on the part of drivers. For example, US SUV drivers were found to be less likely to wear their seatbelts. and showed a documented tendency to drive more recklessly (most sensationally perhaps, in a 1996 finding that SUV drivers were more likely to drive drunk).
Actual driver death rates are monitored by the IIHS and vary between models. These statistics do show average driver death rates in the U.S. were lower in larger vehicles from 2002–2005, and that there was significant overlap between vehicle categories.
US Driver Death Rates from 2002–2005 in recent models (per million registered vehicles)
The IIHS report states, "Pound for pound across vehicle types, cars almost always have lower death rates than pickups or SUVs." It should be noted that these rates are per million registered vehicles and do not account for driver profiles and thus do not include such factors as driver ability, age, climate, gender, miles driven per year, and traffic conditions. The NHTSA recorded occupant (driver or passenger) fatalities per 100M vehicle miles traveled at 1.16 in 2004 and 1.20 in 2003 for light trucks (SUVs, pick-ups and minivans) compared to 1.18 in 2004 and 1.21 in 2003 for passenger cars (all other vehicles).
, sometimes known as the 'SUV subsidy' allows small-business owners to deduct up to $25,000 of the cost of a vehicle with a gross vehicle weight rating
of over 6000 pounds (2,721.6 kg) from their income for income tax
calculation. Small-business owners may deduct $10,610 of the cost of a passenger automobile. This provides a slight tax incentive for businesses to purchase larger / commercial vehicles, such as SUVs, which is criticised on environmental grounds. However, the cost of both SUVs and automobiles is fully deductible over future years using normal depreciation. In previous years, this deduction reached $120,000 and was the subject of much criticism. When the vehicle is eventually sold, the difference between the sale price and depreciated value must be claimed as income and is subject to taxation.
s, and thus are subject to the less strict light truck standard under the Corporate Average Fuel Economy
(CAFE) regulations, and SUVs which exceed 8,500 pounds GVWR have been entirely exempt from CAFE standards. The CAFE requirement for light trucks is an average of 20.7 miles per US gallon, versus 27.5 miles per US gallon for passenger cars. This provides less incentive for U.S. manufacturers to produce more fuel efficient models.
As a result of their off-road design SUVs may have fuel-inefficient
features. High profile increases wind resistance
and greater mass requires heavier suspensions and larger drivetrain
s, which both contribute to increased vehicle weight. Some SUVs come with tire
s designed for off-road traction rather than low rolling resistance.
Fuel economy factors include:
Average data for vehicle types sold in the U.S.A:
Drag resistance (same drag coefficient) for SUVs may be 30% higher and the acceleration force has to be 35% larger than family sedans if we use the figures from the above table. This gives a 40% higher fuel consumption (even for parallel hybrid electric SUVs) using the given formula for the power demand.
Addressing fuel efficiency, several manufacturers now offer hybrid gas/electric models of SUVs, offering improved fuel economy over conventionally powered SUVs. With some hybrid SUV models, the added power generated from the hybrid systems is used some times to give vehicles added performance (increased power). SUVs with hybrid engines can therefore experience gas mileage similar to that of gas powered family sedans.
or Les Dégonflés
have targeted SUV dealerships and privately-owned SUVs because of concern over increased fuel usage. Acts can range from criminal damage (such as arson or deflating the vehicle's tires) to more passive attacks (such as fake 'parking tickets').
In the U.S., light trucks and SUVs are held to a less-strict pollution control standard than passenger cars. In response to the perception that a growing share of fuel consumption and emissions are attributable to these vehicles, the Environmental Protection Agency ruled that by model year 2009, emissions from all light trucks and passenger cars will be regulated equally.
However, total mileage over time must be taken into consideration when considering total emissions volume and there has been investigation in 'Dust to Dust' environmental impact; considering factors other than fuel economy.
The British national newspaper The Independent
reported on a study carried out by CNW Marketing Research
which suggested that CO2 emissions alone do not reflect the true environmental costs of a car. The newspaper reported that: "CNW moves beyond the usual CO2 emissions figures and uses a "dust-to-dust" calculation of a car's environmental impact, from its creation to its ultimate destruction. The newspaper also reported that the CNW research put the Jeep Wrangler
above the Toyota Prius
and other hybrid cars as the greenest car that could be bought in the US. However, it was noted that Toyota disputed the proportion of energy used to make a car compared with how much the vehicle uses during its life; CNW said 80% of the energy a car uses is accounted for by manufacture and 20% in use - Toyota claimed the reverse.
The report has raised controversy. When Oregon radio station KATU asked for comment on the CNW report, Professor John Heywood (with the Massachusetts Institute of Technology (MIT)) saw merit in the study saying "It raises in the rest of us some good questions" but "I can only guess at how they did the detailed arithmetic. ... The danger is a report like this will discourage the kind of thinking we want consumers to do - should I invest in this new technology, should I help this new technology?"
The Rocky Mountain Institute
alleged that even after making assumptions that would lower the environmental impact of the Hummer H3 relative to the Prius; "the Prius still has a lower impact on the environment. This indicates that the unpublished assumptions and inputs used by CNW must continue the trend of favoring the Hummer, or disfavoring the Prius. Since the researchers at Argonne Labs performed a careful survey of all recent life cycle analyses of cars, especially hybrids, our research underlines the deep divide between CNW's study and all scientifically reviewed and accepted work on the same topic.".
A report done by the Pacific Institute
alleges "serious biases and flaws" in the study published by CNW, claiming that "the report's conclusions rely on faulty methods of analysis, untenable assumptions, selective use and presentation of data, and a complete lack of peer review."
For his own part, CNW's Art Spinella says environment campaigners may be right about SUVs but hybrids are an expensive part of the automotive picture; the vehicle at the top of his environmentally friendly list is the Scion XB because it is easy to build, cheap to run and recycle and carries a cost of 49 cents a mile over its lifetime.
"I don't like the Hummer people using that as an example to justify the fact that they bought a Hummer," he said. "Just as it's not for Prius owners to necessarily believe that they're saving the entire globe, the environment for the entire world, that's not true either."
The June 2008 release of the "From Dust to Dust" study now places the Prius cost per lifetime mile fell 23.5% to $2.191 per lifetime mile while the H3 cost rose 12.5% to $2.327 per lifetime mile -although as it is still dependent upon the distance driven during the vehicle's life, is still subject to dispute.
and Hummer H2
) technically limits their use on certain roads. These laws are rarely enforced for SUVs as they are classified as passenger vehicles instead of commercial trucks. Fortunately these small rural roads are a rare occurrence for most drivers. In addition many of these rural byways are giving way to more efficient and larger two lanes which support vehicles up to medium weight trucks.
The weight of a passenger vehicle has a direct statistical contribution to its driver fatality rate according to Informed for LIFE

and Vienna
have debated banning them altogether.
where most on-road motor vehicles (except very low polluters) are subject to yearly vehicle excise duty
payments, the government is actively attempting to deter people from using high-CO2 vehicles by taxation with a high vehicle excise duty. The average family sized car would cost around £175 GBP annually (2009), whereas more polluting vehicles (including some SUVs) cost up to £440 GBP based on the CO2 g/km emissions with further increases planned in the future.
However, by selecting a pick up truck, which are similar in all other respects to SUVs, the high taxes can be offset by the reduction in VAT and company car tax each year.
since the mid-late 2000s.
In the late 1990s and early 2000s, the Big Three could enjoy profit margins of $10,000 per SUV, while losing a few hundred dollars on a compact car. Consequently, these companies focused resources and design on SUVs over small cars (compact cars were sold mainly to attract young buyers with inexpensive options and to increase their fleet average fuel economies to meet federal standards). As a result of the shift in the Big Three's strategy, many long-running compact and midsize cars like the Ford Taurus
, Buick Century
, and Pontiac Grand Prix
eventually fell behind their Japanese competition in features and image (relying more upon fleet sales instead of retail and/or heavy incentive discounts), some eventually being discontinued. Jerry White
With soaring gas prices in the mid-late 2000s, followed by a weakening economy
, SUV and light truck sales have declined significantly. The Big Three were unable to adapt as quickly as their Japanese rivals to produce small cars and crossovers to meet growing demand for fuel-efficient vehicles; the U.S. offerings were also considered less competitive than their Japanese counterparts. This was due to inflexible manufacturing facilities, the high wages of unionized workers in the United States and Canada (members of the UAW
and CAW
, respectively) compared to non-union workers such as that of Toyota, make it unprofitable to build small cars,

Rollover
A high center of gravity makes a vehicle more prone to rollover accidents than lower vehicles, especially if the vehicle leaves the road or in emergency maneuvers. Figures from the US National Highway Traffic Safety Administration show that most passenger cars have about a 10% chance of rollover while SUVs have between 14% and 23% (varying from a low of 14% for the AWD Ford Edge to a high of 23% for the FWD Ford Escape). Many modern SUVs are equipped with electronic stability controlElectronic stability control

Construction
Heavier SUVs are typically built with a truck-style chassis with separate body, while some newer, lighter or cross-over models are more similar to car construction, which are typically built with a monocoque unitary construction (where the body actually forms the structure of the car). Separate chassis style designs have typically a higher center of gravity than a vehicle of unibody construction.The British television Fifth Gear

Larger vehicles can create visibility problems for other drivers by obscuring their view of traffic lights, signs, and other vehicles on the road, plus the road itself.Depending on design, drivers of some larger vehicles may themselves suffer from poor visibility to the side and the rear. Poor rearward vision has led to many "backover deaths" where vehicles have run over small children when backing out of driveways.

Wide bodies in narrow lanes
The wider bodies of larger vehicles means they occupy a greater percentage of road lanes, leaving less room for error and for other road users. This is particularly noticeable on the narrow roads sometimes found in dense urban areas or rural areas in Europe. Wider vehicles may also have difficulty fitting in some parking spaces and encroach further into traffic lanes when parked alongside of the road.Psychology

The marketing techniques used to sell SUVs have been under criticism. Advertisers and manufacturers alike have been assailed for greenwashing. Critics have cited SUV commercials that show the product being driven through a wilderness area, even though relatively few SUVs are ever driven off-road.Tax benefits

In previous years, this deduction reached $120,000 and was the subject of much criticism. When the vehicle is eventually sold, the difference between the sale price and depreciated value must be claimed as income and is subject to taxation.
Fuel economy
The recent popularity of SUVs is sometimes given as one reason the U.S. population has begun to consume more gasoline than in previous years. SUVs are generally more wasteful of fuel than passenger vehicles or minivans with the same number of seats. Additionally, SUVs up to 8,500 pounds GVWR are classified by the U.S. government as light truckLight truck

(CAFE) regulations, and SUVs which exceed 8,500 pounds GVWR have been entirely exempt from CAFE standards. The CAFE requirement for light trucks is an average of 20.7 miles per US gallon, versus 27.5 miles per US gallon for passenger cars. This provides less incentive for U.S. manufacturers to produce more fuel efficient models.
As a result of their off-road design SUVs may have fuel-inefficient

- High cross-sectional area causing very high drag losses especially when driven at high speed where stands for the power, for the cross-sectional area of the vehicle, for the density of the air and for the relative velocity of the air (incl. wind).
- High rolling resistance due to all-terrain tires (even worse if low pressure is needed offroad) and high vehicle mass driving the rolling resistance where stands for the rolling resistance factor and for the vehicle mass.
Average data for vehicle types sold in the U.S.A:
Type | Width | Height | Curb weight | Combined fuel economy | |||||
---|---|---|---|---|---|---|---|---|---|
in | cm | in | cm | lb | kg | mpg (US) | l/100 km | mpg (imp) | |
SUVs | 70.5 | 187 | 69.7 | 180 | 4442 | 1924 | 19.19 | 12.26 | 23.05 |
Minivans | 75.9 | 193 | 67.2 | 178 | 4075 | 1939 | 20.36 | 11.55 | 24.45 |
Family sedans | 70.3 | 179 | 57.3 | 146 | 3144 | 1426 | 26.94 | 8.731 | 32.35 |
Drag resistance (same drag coefficient) for SUVs may be 30% higher and the acceleration force has to be 35% larger than family sedans if we use the figures from the above table. This gives a 40% higher fuel consumption (even for parallel hybrid electric SUVs) using the given formula for the power demand.
Addressing fuel efficiency, several manufacturers now offer hybrid gas/electric models of SUVs, offering improved fuel economy over conventionally powered SUVs. With some hybrid SUV models, the added power generated from the hybrid systems is used some times to give vehicles added performance (increased power). SUVs with hybrid engines can therefore experience gas mileage similar to that of gas powered family sedans.
Pollution
Because some SUVs can use more fuel (mile for mile) than cars with the same engine type, it is sometimes suggested that they generate higher volumes of pollutants (particularly carbon dioxide) into the atmosphere. Various eco-sabotage groups, such as the Earth Liberation FrontEarth Liberation Front

have targeted SUV dealerships and privately-owned SUVs because of concern over increased fuel usage. Acts can range from criminal damage (such as arson or deflating the vehicle's tires) to more passive attacks (such as fake 'parking tickets').
In the U.S., light trucks and SUVs are held to a less-strict pollution control standard than passenger cars. In response to the perception that a growing share of fuel consumption and emissions are attributable to these vehicles, the Environmental Protection Agency ruled that by model year 2009, emissions from all light trucks and passenger cars will be regulated equally.
However, total mileage over time must be taken into consideration when considering total emissions volume and there has been investigation in 'Dust to Dust' environmental impact; considering factors other than fuel economy.

However, it was noted that Toyota disputed the proportion of energy used to make a car compared with how much the vehicle uses during its life; CNW said 80% of the energy a car uses is accounted for by manufacture and 20% in use - Toyota claimed the reverse.
The report has raised controversy.

alleges "serious biases and flaws" in the study published by CNW, claiming that "the report's conclusions rely on faulty methods of analysis, untenable assumptions, selective use and presentation of data, and a complete lack of peer review."
For his own part, CNW's Art Spinella says environment campaigners may be right about SUVs but hybrids are an expensive part of the automotive picture; the vehicle at the top of his environmentally friendly list is the Scion XB because it is easy to build, cheap to run and recycle and carries a cost of 49 cents a mile over its lifetime.
"I don't like the Hummer people using that as an example to justify the fact that they bought a Hummer," he said. "Just as it's not for Prius owners to necessarily believe that they're saving the entire globe, the environment for the entire world, that's not true either."
The June 2008 release of the "From Dust to Dust" study now places the Prius cost per lifetime mile fell 23.5% to $2.191 per lifetime mile while the H3 cost rose 12.5% to $2.327 per lifetime mile -although as it is still dependent upon the distance driven during the vehicle's life, is still subject to dispute.

Size
The length and especially width of large SUVs is controversial in urban areas. In areas with limited parking spaces, large SUV drivers have been criticized for parking in stalls marked for compact cars or that are too narrow for the width of larger vehicles. Critics have stated that this causes problems such as the loss of use of the adjacent space, reduced accessibility into the entry of an adjacent vehicle, blockage of driveway space, and damage inflicted, by the door, to adjacent vehicles.

The average family sized car would cost around £175 GBP annually (2009), whereas more polluting vehicles (including some SUVs) cost up to £440 GBP based on the CO2 g/km emissions with further increases planned in the future.
However, by selecting a pick up truck, which are similar in all other respects to SUVs, the high taxes can be offset by the reduction in VAT and company car tax each year.

In the late 1990s and early 2000s, the Big Three could enjoy profit margins of $10,000 per SUV, while losing a few hundred dollars on a compact car. Consequently, these companies focused resources and design on SUVs over small cars (compact cars were sold mainly to attract young buyers with inexpensive options and to increase their fleet average fuel economies to meet federal standards). As a result of the shift in the Big Three's strategy, many long-running compact and midsize cars like the Ford Taurus
