Tomberlin is part of the Nordic Group of Companies, a family-owned management and manufacturing business headquartered in Baraboo, Wisconsin with manufacturing operations extending throughout the United States, Mexico, and Europe and includes Flambeau and Seats Incorporated, leaders in their respective industries. The Nordic Group believes a fiscally conservative approach to business and managed growth leads to long-term sustainability. These ideals as well as our founder’s core values of; family, integrity, leadership, teamwork, knowledge and excellence permeate our organization and day-to-day decisions.

Our product line’s heritage stretches back to 1946, making Columbia the most experienced manufacturer in its field, and has been cared for by such well-known brands as Westinghouse and Harley Davidson.


American workers in Reedsburg, Wisconsin assemble each of Columbia’s products with a focus on producing vehicles with the longest life-cycle in the industry. Using the highest quality materials available, Columbia’s energy efficient vehicles will serve our customers well for years to come. We believe a product that lasts longer reduces our overall impact on the environment. With this same concern for the environment in mind, Columbia is one of a handful of vehicle manufacturers committed to exclusively building Pure Electric vehicles. As we work to reduce our overall impact on the environment, it is encouraging to know our final product is propelled by the cleanest commercially viable energy source with zero tailpipe emissions. All of Columbia’s manufacturing processes are in compliance with each applicable governing body’s most stringent requirements.

As compared to its competitors, Columbia’s vehicles include:

  • Steel frames and bodies that utilize thicker gauged steel (longer-life)
  • The most robust drive motor (better operation in hot/harsh environments)
  • The most efficient power control system (more usable range on a charge)
  • The most efficient charger (less energy used to charge vehicle)
  • Intelligent energy recovery braking (wasted energy recycled to recharge batteries)
  • Easily programmable performance characteristics (only energy actually needed is expended)

While all of Columbia’s vehicles are designed to operate as efficiently as possible in their respective environments, vehicles that will be operated on public roads meet or exceed all applicable NHTSA standards. Columbia has received the highest rating possible, a 10 out of 10, for our global warming and smog scores on the environmental performance label issued by CARB (California Air Resource Board). This is significant, as a typical internal combustion vehicle only receives a 5 out of 10 for both these ratings.
