With an eye on the 2014 Sochi Olympics, BMW of North America and the U.S. Bobsled and Skeleton Federation have been working for more than a year on the development of a new two-man bobsled.
The deal is being announced Wednesday.
A prototype has been delivered already, and testing is ongoing to make the sled as fast as possible.
Some U.S. drivers, including reigning Olympic and world champion Steven Holcomb, tested the prototype on the 2002 Olympic track in Park City, Utah earlier this year.
BMW says it is bringing lighter material, along with "optimized aerodynamics and chassis dynamics" to the sled-design process.
