One of the problems with MPG
is that there are no common parameters.
The quarter-mile is the quarter-mile regardless of vehicle.
The pulling sled is set by the first puller and then stays constant.
Many parameters affect MPG
: Weight, air temp and humidity, filling technique, altitude, hills, speed, and road conditions.
What we lack is a agreed set of conditions. Geting everyone's conditions is Mission: Impossible, unless it is one in a single situation in a single time period.
This is why a MPG
Road Run is the only really fair way to sort everyone out.
Here is my suggestion (stealing a lot from the bold Mobil Economy runs of the 50s and 60s.)
Pick a set course. The course needs to be at least 800 miles long. The longer the better. That averages out differences in filling techniques. The course should have varied terrain and roads - a mix of urban/suburban, two-land roads, Interstates, and maybe some dirt roads. The route is pre-run to do two things: Filter out construction zones and fix the overall mileage. the route should begin and end at roughly the same altitude to zero out the net effects of hills. Speed? To me there is only one fair speed: the posted limit minus two MPH. There would have to be a penalty for driving excessively below the limit.
Trucks would be ballasted to an agreed weight. Probably the GVWR
of the lightest truck. Maybe you have different weight classes to accommodate smaller trucks and even Class Eights if they want.
A suggestion for a route: Sea-to-Shining Sea. Savannah to San Diego, Miami-to-Seattle (probably a bit long), NYC-to Frisco.
Yup. I'm talking a minimum of a week. Still shorter than a DHRA season. The prize: Unmitigated bragging rights - priceless.
The details are not set in stone. Whaddya think?
