OK, now for the results by class. The length of today's course was verified by two GPS units at 107.5 miles. These results were calculated from that distance.
Gas Class
1. Chang Ho Kim - 1989 Honda CRX - 95.98 mpg
2. Will Meredith 1998 - Honda Civic EX - 61.43 mpg
3. Mike Kamm - 1993 Nissan Sentra SE-R - 60.73 mpg
4. Richard Vedder - 2000 Ford ZX2 S/R - 51.20 mpg
5. Jeffrey Dungen - 1992 Toyota Levin GT-Apex - 50.95 mpg
6. Robert Kerly - 1998 Mercury Tracer - 41.51 mpg
7. Ernie Yue - 2001 Ford Focus - 40.88 mpg
8. Dan Wren - 1986 BMW 325ES - 40.41
9. Steve McKelvie - 2003 Mercedes-Benz SLK230 - 39.96 mpg
10. Tom Compoli - 1981 VW Rabbit - 34.90
Diesels and Hybrids
1. Robert Smalls - 2000 Honda Insight - 86.73 mpg [See note below]
2. Martin Deschenes - 2000 VW Jetta TDI - 74.65 mpg
3. Hobbit - 2004 Toyota Prius - 63.9 mpg [See note below]
Historic Class
1. Bruce Turk - 1958 Saab 93B - 36.32 mpg [See note below]
Notes:
This was Bruce Turk's first economy run event ever. He basically cruised the entire course at between 40-45 mph with his little 2-stroke pwered Saab. Original fuel economy numbers for the day on that car were 29-31 mpg. Bruce was happy with his 36.32 mpg. However, with his tank topped fully from this event, he drove the 114 miles back to his home at a [GPS calculated] average speed of 59.8 mph. He filled up again and checked his mileage. He was very surprised at what he found. He achieved 45.6 mpg! To me it makes sense, as we all know that all 2 cycle engines definitely have a sweet spot. Unfortunately for Bruce, he didn't learn what it was until after the event!
As we have learned from holding these events, there are times when the usual top up refill calculation process can sometimes be unreliable and/or inaccurate. Ben Jones' CRX had this problem in Economy Run III. In that case we revert back to what the in car mpg display unit says, and then subtract 2% [the usual error with facory units]. With that said, Robert Smalls' Insight had an unreasonably low mpg outcome at 63.61 mpg. His factory in car unit showed 88.5 mpg. This is a large discrepancy, so we discussed during the awards and all agreed we should revert back to his display figure, minus 2%.
With their rubber fuel tank bladders, the Prius' don't fill properly either. So Hobbit's initial reading of 55.41 has also been corrected to 63.90 in the same fashion as Robert's.
