GM statement on magnesium manifold

Doug Duchardt
NASCAR Group Manager, GM Racing

"We are very disappointed in the penalties by NASCAR against Hendrick Motorsports and Jeff Gordon.

"We supplied these magnesium intake manifolds to our teams in the clear belief that they are allowed under the rules. They are identical in shape and dimensions to the comparable aluminum manifold, produce no increase in horsepower and NASCAR has, on many occasions, permitted changes in materials of components where not explicitly prohibited by the rules. There is no mention of materials in the rule on intake manifolds.

"There has never been any intent by GM Racing to provide these parts to teams secretly or to secure an unfair advantage by doing so. NASCAR technical officials have been aware of the use of this manifold for some time. Moreover, on multiple occasions, engines using these manifolds have been inspected by NASCAR and pronounced satisfactory.

"We pride ourselves on having open, constructive communications with NASCAR officials on all matters, especially technical ones. Our track record over the years is proof enough of that. We followed the same process as before and believed that the submission of a new part to NASCAR for approval was not necessary.

"It is deeply regrettable that this situation has occurred."
