While we're at it; these guys had a busy summer:
TU Delft students beat the world record for electric car acceleration | RobAid
(0-100 km/h in 2.13 seconds)

Check this movie:
Slightly off-topic as aerodynamics are not the prior point of attention here, but I hope that it can be allowed for once

Cheers, Bart (@TU Delft 1983-1988)

I agree - I like the Quest velomobile because it is a practical vehicle; with three wheels and the rider can get in and out all on their own.

The actual run up to the 200 meter timing traps is 5 miles. It does get very warm inside once all the covers are in place but not unbearably so. After the traps is a mile to allow the bike to slow down before the catch area.

Nor is it supposed to be. These bikes are made specifically to set human powered speed records although a few of the slower ones(50 to 60mph) are streetable and able to self launch and stop.

My mistake ( or is the new terminology supposed to be "my bad " )

Yes, my mistake. I saw the hole in the nose right after I posted. I was actually thinking of the HPV racers from the previous years that were devoid of this hole.

Gyronaut X-1? It was supposed to run at Bonnevile this year with a Triumph engine, but had technical difficulties. This was going to be the push car:






Wouldn't it be faster backwards? If only because it would be less likely to upset?
