Typical Canadians. Their country's flag is smaller than the GMC logo. I hope someone from UofT alumni relations gives them a call. If you are going for a speed record, you need something more like this: http://cdn.rsvlts.com/wp-content/uploads/2014/02/olympics-sk...

This isn't horribly safe, either. Wiping out at 85 MPH would suck . I'm curious what multi-cyclist vehicles could do, now that you suggest it. With the lightness of these vehicles, at what point would you have to add spoilers?
While I know it would suck to wipe out, I'm hoping with this thing it may be more of a "slide for 1000ft and off the flat road" type of suck than a "life altering injury" type of suck.
Sadly, the video is pretty cheesy and content-free. It's hard to recommend.
So my question is now: In terms of aerodynamics, what aren't they doing? Some commentators have noted that the shape of this bike is just about as good as it can get. The rider/engine is also not going to see any vast improvements. So rather than this become a pure athletic event, where can engineers look for improvements? Will they have to start dealing with boundary layer issues? Will the next generation of bike be…

I found out they have great Q&A videos on their YouTube channel. They answer here why golf ball dimples are unnecessary for a fin-like shape. https://www.youtube.com/watch?v=ZXpZy_A7mMk

I am a proud Canadian who lives in the USA and have a little Canadian sticker on my car. It's my little shout out to other Canadians on the road. I guess we're quietly showing our pride to others. Being loud about it is not in our nature. But I do like that luge helmet :)

Just spitballing here, I have no idea how most of this stuff works.

Golfball-like dimples are only half my question. In aircraft much work has been done on reducing boundary layer issues with suction holes that actively remove turbulent air. Some aircraft engines, the SR-71's in particular, do this to ensure 'clean' intake air.

It's not luge. When the idiot goes head-first they call it skeleton.

Would the multiplied power be offset by the multiplied weight and potential loss of aerodynamics?
Max speed has very little to do with weight as long as you have sufficient room to accelerate. Additional drag would be small if you put one rider in front of the other and both inside of a fairing. The frontal area and shape could stay the same. This is the major source of drag. There would be small amounts of additional drag from the air running along a longer fairing, but doubling the power would more than make up…
