Examples
The first generation of American vans were the 1960s compact vans which were patterned in size after the Volkswagen Bus. The Corvair based entry even aped the rear mounted air cooled engine design. The Ford Falcon had a flat nose with engine mounted between and behind the front seats. The Dodge A100 had a similar layout and could accommodate a V-8. Chevrolet also switched to this layout. The Ford, Dodge and Corvair vans were also produced as pickup trucks.
The standard or full size vans appeared with Ford's innovation of moving the engine forward under a short hood and using pickup truck components and taillights. The engine cockpit housing is often called a dog house. Over time, they evolved longer noses and sleeker shapes. The Dodge Sportsman added a plug to the rear of a long wheelbase to create the 15 passenger van. They have been sold as both cargo and passenger models to the general public and as cutaway van chassisversions for second stage manufacturers to make box vans, ambulances, campers and other vehicles. Second stage manufacturers also modify the original manufacturer's body to createcustom vans for the general public.
In the 1970s, songs like "Chevy Van" and nicknames like "sin bin" became part of the culture as owners transformed them into rolling bedrooms and lounges. Conversion vans became a large market with plusher accommodations than factory seats.
Dodge ended production of their full-size vans in June of 2002 (as 2003 models), and replaced it with the Dodge Sprinter, which is based on a narrower, more fuel efficient European design pattern with a 150 hp (110 kW) diesel turbo I5. Typical versions of the Sprinter are taller than other unmodified vans (tall enough to stand in), with a more slanted (aerodynamic) profile in front. They have been adopted primarily for delivery and lightweight Class-C van cab motorhome applications.
[edit]Usage
In urban areas of the United States full-size vans have been used as commuter vans since 1971, when Dodge introduced a van that could transport up to 15 passengers. Commuter vans are used as an alternative to carpooling and other ride sharing arrangements.
Many mobile businesses use a van to carry almost their entire business to various places where they work. For instance, there are those who come to homes or places of business to perform services or to install or repair appliances.
Vans are also used to shuttle people and their luggage between hotels and airports, to transport commuters between parking lots and their places of work, and along established routes as minibuses.
Vans are also used to transport elderly and mobility-impaired worshipers to and from church services or to transport youth groups for outings to amusement parks, picnics, and visiting other churches.
[edit]Step Van
Another type of van, peculiar to North America, is the step van, so called because of the ease with which one can step in and out of it. Widely used by delivery services, courier companies and the parcel division of US Mail and Canada Post, they are often seen driven with the door open, especially in big cities.
[edit]Rollover safety
Recently, the larger passenger versions have appeared in news stories for having a tendency to roll over, particularly in the case of inexperienced operators. The van body is taller than the cab and bed of the pickup that uses the same style frame and powertrain resulting in the basic van having a higher center of gravity than a similarly loaded pickup from which it is derived. The suspension is also higher because of the extreme weight capacity of 15 passengers of between 150 lb (68 kg) and 200 lb (91 kg) each which may be over one ton of passengers alone. The seats in the passenger version raise the load, passengers, above the floor, further raising the center of gravity (and often shifting it rearward). The bench seats allow passengers to slide if safety beltsare not used. In the United States it is common for only the front seat passengers to use their safety belts, perhaps because belted passengers feel they can still lean and shift a large amount. However, the NHTSA, cited below, has determined that belted passengers are about 4 times more likely to survive in rollover crashes.
Safety can be greatly improved by understanding the unique characteristics of 12- & 15-passenger vans and by following a special set of guidelines developed for drivers, according to the U.S. National Highway Traffic Safety Administration (NHTSA). A summary of this information is available at Reducing The Risk of Rollover Crashes in 15-Passenger Vans.Among other things, this document advises that carrying 10 or fewer passengers (preferably towards the front of the van) greatly reduces the risk of rollover crashes, and it suggests that repeated operation by the same drivers tends to increase their ability to handle these vehicles more safely over time. Car rental companies have also started adding stickers to warn renters about the difference in handling while compared to standard cars. Items should not be added to a roof rack of an already top-heavy vehicle.
