Welcome To The Official Green Grand Prix Web Site

138.5 miles / 1.026 gallons = 135.0 mpgUS

during the Green Grand Prix on the track at Watkins Glen, NY USA. 45mph average speed, 90% tuck laying on a tank bag, three hour event. I used full on Pulse And Glide and Engine Off Coasting. Probably posted the best actual fuel economy of all the vehicles competing but won't get credit for it as the vehicles without built in computers were required to calculate the fuel usage by the total weight lost using scales. This was totally inaccurate. I did my own tank fill in town before and after to get the real numbers.

Home and back between days at Watkins Glen.

Over the road rally at Watkins Glen. Pouring rain and 45F. With observed fill ups. The guy in the Heinkel whipped us all with 124 mpg His "good" home made bullet vehicle blew the engine last week so we were spared from seeing him hit 160.
.

The event was very well organized for the 38 cars, and one bike, that were on the track and had a sea of volunteers including professional flag men and ladies who called you up to start on a dime with strict precision and waved you off, and home, with a flurry of green, white and checkered flags! Very cool. Full spotters with radio headsets. They black flagged team Lexus as the car did several laps drafting the SUV at about 10 feet. I wish they had seen the jerk in the white Insight that tried to block me from passing up the hill out of turn 2. I was already even with his driver's window when he pushed me to within 6 inches of the curb. When the horn didn't work I should have knocked on the glass to ask him to calm his road rage. Lucky for him he was on my throttle side and I didn't fee like letting go as it is a very steep hill. The Insights were the cars to stay away from as they would sometimes use heavy braking into turn 1 to regen their batteries. It was a little crowded at times but I generally had a great run. Turn 1 is no joke as you dive down 50? feet through the tight right angle. I was just shy of dragging a knee. It was one of the turns that had a speed limit of 40 and was actually pretty extreme if you mis calculated your entry speed as the team of Michigan college students did when they spun it at 50! Luckily there was no roll over and they were able to continue their run after getting it pointed the right way again. It was a beautiful day Friday. Saturday, not so much. Too bad my blue tooth audio drained my battery or I would have had more photos to share.
.
Saturday dawned overcast and cool but the rain held off for my hour commute back the the Glen for the 6:15AM mandatory observed fill up. So I was able to stay dry while we hung around the paddock for the drivers meeting before heading out for the road rally. A front moved in just as we were starting. The temps dropped into the low 40's F and a heavy mist started blowing sideways out of the West. Visibility was 100 feet at best. Not the nicest day for a 3 hour motorcycle ride. Or car ride as one guy found out when he rolled his driver's window down at a check point and it jumped off the track. By the time I got to the half way point at the top of the lake, It had changed to pouring rain. Motorcycle(s) were allowed to run a simplified route according to a map rather than using the TSD rally turn by turn instructions so I wasn't under the gun to hit any exact times. My hands were pretty cold by the 3/4 point so I went in to McDonalds to grab a burger and hot drink. This worked out well as I was the 3rd vehicle in at the end for our refill. It was really fun to hang around to watch all the other cars check in. The driver of the ultra cool factoryfive kit car liked my over boots. His pants and shoes were soaked to the knee as the car picked up an inch of water on the floor through it's leaky doors. The professional photographer shot 100's (thousand?) of photos so I hope most of this gets posted somewhere.
.
I made the mistake of mentioning when I checked in at the track that most of the competitors were here to contest their fuel economy and would probably rather not have to run a puzzling TSD rally. The team of SCCA racing enthusiasts laboriously grading and pointing the check in sheets jumped all over me and told me to go find another event. Sorry! I won't mention it again. Unfortunately, there are very few other fuel economy events anywhere and it seems that SCCA sanctioning is the only way to get this done. Maybe I will join the SCCA to try to enlighten them about hypermiling as a new form of competition. It really is a cool sport and harkens back to the days of endurance racing in the 60's where the only rules were to pass a safety inspection and you might have big block V8's running against turbo 4's or high revving V12's. Hypermiling is the new "run what you brung" competition.

Wow, that's incredible that you got that mileage out of this bike! And to think I was happy as could be when i hit 71.8mpg. LOL How low were you upshifting? I'd imagine you never let it get above about 4 grand right? Were you running a real high PSI in your tires?

Oh and I would have hunted down the POS in the insight after ya'll were done!! It's nice that some people put their gas mileage above your life.

Should have drank as much water as you could hold during your stop to offset the fuel weight loss.

"Impossible! This CBR250R actually PRODUCED gas during the run!"

Cool report. Looking forward to how you do at the CV Challenge.

There was no shifting on the track other than the start and taking off after the 3 required, 4.5 minute pit stops, so that was a non issue. Tires were 36, 36 both days. The big gain came from being engine off all the way from the beginning of the pit wall, down the entire front straight, through turn 1, to the base of the uphill at the entry to turn 2. The entire back straight is slightly up hill and was into a stiff headwind so that turned out to be a high load pulse even though the speed and rpm were fairly constant around 4,500-5,000. The glide was with the tail wind pushing me all the way down the front straight after gunning it up to 52 mph through the last turn and killing the engine at the edge of the pit wall.
.
The road course was on country roads up one side of the lake and back down the other and had very few traffic lights or stops as well. I was pulsing from 4,000 to 5,000 most of the way as traffic would allow but now wonder if this engine might have done better to just run at 4,500, 45 mph, with the lightest load possible. I need to get my MPGuino finished so I can experiment with different techniques to find the best. I hope to do even better with a tail on the bike next year. 150mpg might not even win it if my neighbor shows up with his home built bullet three wheeler.

Great job! Sounds like it got a little crazy at times - glad you survived!

Thanks for posting. Looks like fun!
