The proving grounds also include a new 1.3m square foot vehicle dynamics area and a modified powersports complex to support the development testing of Honda motorcycles as well as all terrain vehicles and side by side vehicles designed, developed and manufactured in America. All original and existing asphalt was recycled on site and used in the rehabilitation of the facility.

"The enhancements we have made will play an important role in advancing the performance capabilities of our products for our customers," said Jeff Conrad, senior vice president automobile division, American Honda. "HPC has long played a valuable role in the development of our products and this renovation will ensure it continues to do so."

The renovation of the 3,840 acre, warm weather testing facility provides Honda with two key US proving grounds for the development and testing of new automobile and powersports products. Honda also conducts product testing and verification at the Transportation Research Center, an automotive proving centre near one of its assembly plants in East Liberty, Ohio.
