- Special thanks go out to Bodrodz crew, Ed Desmond and Ron Zito for helping make this run possible. Doug Anderson at the wheel. Car doesn't roll off until 4:30 in the video. Run was made mid afternoon. Road was a little busier than we wanted. Just had to wait our turn for a gap to present itself so wouldn't catch anyone on the way down. The car had yet to have the 4" gaps sealed on the belly pan and aero windscreen installed. I did use brake on the run because of traffic and shut the run down early. This car will go faster. Some more testing on some slower hills and we'll be back later this fall.
4:27 is when he starts moving
I like the Atomic Splinter best of all Gravity Cars ever seen. Well done Bodrodz crew!
How doesn't this video have millions of views?
Glad you installed brakes
Mr FAST, congratulations !
Like to see an edit with more camera angles.Just a matter of time before a proper track is built for the gravity gran Prix!
Epic, awesome job guys
Overtaking would be an interesting proposition.
4 wheel disc they are a must
holy hell that looks like fun!
Congratulations! I guess it's the soapbox world record. In street luge it's 97.8 mph = 157.4 Km/h in Les Eboulements ( Canada ). In this same road which do you think would be faster?
Mozzman, I believe you might be wrong about the dynamics on that gravity car vesrus a streetluge. While a luge has a smaller frontal area, it's hardly 'tidy' (although Hickey's 'Eagle' sleds were kinda slick), and the overall form on the gravity car is similar to a 1970's Le Mans racecar. The added mass of bigger [and likely a tad faster] wheels, more framework, and the bodywork may weigh in here too. As for steering without leaning into the airflow, and braking without burning up Vans shoes, that also adds up to more speed. It also means, that despite the awkward first push, this rig is safer than a sled.
I've been streetluging since 1978, btw, and still have my 2nd and 3rd sleds, one of which is still in use 33 years on. I have Roger Hickey to thank for this dreadful addiction, but it's better than street-drugs, for sure!
I'd love to know what the gradient of that road is!! Mt. Washington and, Rt. 118 in N.H. are epic, as are Ascutney Mountain Rd., and Rt. 9 (East of Wilmington, heading West) in Vermont, and a few spots in the upstate N.Y. area. Ascutney has a 22% grade at it's steepest, making it damn quick in boost, but Rt. 9 was way over 80 mph (how fast, we don't know, Dan rode away from the chase vehicle, which was doing 80).
I know Rt.100A, going down to Rt. 100 from the Coolidge homestead had me at 78 or so (I, also, lost my chase car at 80, but it was a diesel Rabbit,it couldn't go any faster! even downhill,). That cost me not only a new pair of Vans, but burned my feet trying to stop. Yup, would love wheel actuated brakes on my luges; would've saved my knees a lot of cartelidge over the years!
P.S.R.
Perhaps you mean the Chaparral 2J.
No, Chaparrals had air ducts, pulling air under to create downforce. I was thinking more along the lines of a Lola T70.
Speaking of airflow, three of my sled designs we built in '99 had curved fiberglass seatpans nestled in chromoly frame tubing. The idea was to use the curvature of the seatpan as a ground-effects airfoil (inverted wing-ish) and we used brake-bent sheet steel to mount the rear truck(s) the was folded such that it was a diffuser of that airflow. We noted these got more stable above 60 mph, and were darn tough to draft off of. Dan Pulling probably has the only that's still usable.
Personally I think the body is robbing you of close to 10-15 Mph. Wicked run though nice and smooth,
Awesome!
Are you going to post a video of your new speed record in Canada?
Just watch our crazy brit, Guy Martin. He is a motorbike racer, especially known for the Isle of Man TT.
He has also done a tv show "Speed with Guy Martin" where he has attempted and broken several world records.
He saw this video and thought 'I could beat that'.......and he did.
His new world record for a 'Gravity Racer' / soapbox racer now stand at 85.612 MPH set in France.
You should watch the show.
In the show he was well impressed with your design, engineering. He called it ' A work of art'.
Where in NC is this? I'm near Hot Springs NC.
Record good job
Sweeeeeet as fellas. Do you guys have a facebook page i can follow?
good brakes.
Why is it not shaped like a velomobile? A standard velomobile can reach over 100km/h downhill and perhaps 60-70 on the flat depending on the rider. The record breaking velomobiles can hit twice that on the flat. and I'm sure they would be faster than this downhill.
That's why we're building two completely different cars with composite bodies. Will have a lower drag coefficient than any velomobile.
Streetluge would definitely be faster. G car just punches to big a hole in the air plus rolling resistance, and being an open cockpit, with that kind of drag it would make it tough even to make it to 95 mph. Would definitely love to run that road.
RIP Headphone users.
4 fucking minutes of doing nothing, go to 4:30 to see the car actually move
Impressive! But dangerous.
how is this even legal to drive on an open road?
Herrdesrings it's not legal but it's fast.
Either the driver needs to lose weight, or move up the steering rack… no clearance in this design!
Thumbs down.
