The Diesel Hot Rod Association, Inc. (DHRA) was formed to promote and advance automotive sports that involve the use of diesel (compression ignition) engines. Two examples of such sports include drag racing and sled pulling. The DHRA is a diesel motorsports sanctioning body. We are an NHRA-approved alternate sanctioning organization. We work with both NHRA and the SFI Foundation when developing our rules to ensure, as much as is reasonably possible, the safety of our competitors, fans and sponsors.
