Minivan Debate Rages o­n

As your definition of a minivan didn't fit Mr. Otterbein's classification of the Volkswagen (see Letters, WAW - Dec. '03, p.9), this still doesn't leave Chrysler as the producer of the first "small car-based family van that could fit in a garage."

A few years ago, historian Patrick Foster presented the Grumman Kubvan as the earliest minivan. Based around the drivetrain of the Volkswagen Rabbit, the 1983 Kubvan was introduced the year before the Chrysler minivans. Sam Fiorani Society of Automotive Historians Douglassville, PA

Grumman Olsen Kubvan, a small aluiminum van. Many but not all were equiped with VW rabbit diesel engine and running gear. They were made in the mid 80s. They looked like the small postal vans.

THE GRUMMAN OLSON KUBVAN

The Grumman Olson Kubvan is a sophisticated, lightweight, utility vehicle, featuring an all-aluminum, unitized body. Kubvan utilizes the highly reliable Volkswagen Diesel Rabbit powertrain, as well as Volkswagen suspension, steering and brakes. Kubvan is an advanced product of innovative engineering, and has been designed for maximum performance, efficiency and safety

Two Models were built over a two to three year period, a model 70 and a model 100
SEE SPECIFICATIONS

Originally 500 units were built, using the Volkswagen Rabbit Diesel powertrain, a number of were built as electrics and called the KURBWATT. I have found some vehicles with ford tempo gas engines, I do not think these are original. This vehicle has an ALL aluminum body and frame unlike many of the Grumman family of vehicles which are built o­n other manufacturers frames. 50 of theKubvans were sold to Canada Post and located through out the provinces primarily in the west. A number of these units were retired from service in Canada around 1995.

Kurbwatt, same vehicle as the model 70 Kubvan

Beginning in 1980 10 Kurbwatts were built for the  United States Postal Service , these postal delivery vans had a single-seat (for the driver) and had a curb weight of 2,700 pounds. They had a rated pay load of 500 pounds within a 69 cubic foot cargo space. The van was 71 inches high, 144 inches long and had a wheelbase of 99 inches. The body was made primarily of aluminum. Using 14 6-volt lead-acid batteries, the vehicle had a maximum speed of 52 mph and a range of 40 miles o­n a charge (at 30 mph). Designed for start-and-stop operation, it was capable of 350 start/run/stop cycles (typical of a postal delivery operation) o­n a charge. In 1983 another 31 units were built.

The KURBWATT then the KUBVAN were the predecessors of what is now known as the LLV. (Long Life Vehicle) Grumman built 150,000 of these for the U.S. and Canadian Postal Service from 19856 to 1995.

To obtain acopy, contact your dealer or write to: Grumman Olson Customer Service 445 Broad Hollow Road Melville, New York 11747 In 1978 due to the energy crisis, the U. S. Postal Service expressed interest in using electric powered vehicles to deliver the mail.In response to this potential market, Grumman Olson embarked o­n a program to design and develop an all aluminum electric powered mini-van.The proven rugged light weight aluminum construction of the Grumman Olson truck body was a natural starting point for a small vehicle that had to carry 1000 pounds of batteries and still be able to carry the mail man and his mail.During the next three years, Grumman Olson Engineering and Production designed, built, and tested several prototypes to validate the durability and the functionality of the design. The resulting vehicle was all aluminum unitized construction that weighted o­nly 2650 pounds including batteries.Gross vehicle weight including driver and cargo was 3200 pounds.The vehicle was 100% road worthy with all normal automotive systems and equipment and fully certified by testing to comply with all FMVSS requirements for special purpose IC powered vehicles.The vehicle was designed to meet all performance requirements of the USPS including a top speed of 55mph, 0 to 30 acceleration in 14 sec., and the 350 start/stop cycles. In 1981 the first ten production Kurbwatts were delivered to the USPS in Evansville, IN for use o­n regular mail delivery routes.Based o­n the success of these vehicles and input from the Postal Service, the design was further improved and in 1983 an additional 31 Kurbwatts were put in service in Cupertino, CA.All 41 remained in use by the U.S.P.S. until 1992, and accumulated nearly half a million miles of daily service.Many more Kurbwatts would probably have been built had it not been for the easing of the energy crisis and the lack of improvements in batteries. A few Kurbwatts were also sold to other customers.Six of which were built for Long Island Lighting Co. Long Island, NY in early 1984 for research in the use of electric vehicles.These six vehicles were later donated to major universities around the country for continued research projects.In 1992 two of the LILCO Kurbwatts were acquired by the University of South Florida for use in a solar charging research program.One of the vehicles is still in use today and the other has been interned in the Museum of Science and Industryin Tampa, FL.It serves as the central focus of a solar energy display.Many of the Postal Kurbwatts have now been acquired by private individuals and are still in use today, including o­ne in Bermuda. Grumman Olson demonstrated that a practical electric vehicle could be built to withstand the riggers of daily use.
