McLaren T50. That fan would go well with the Falcon tail lights. All downforce at the center bottom, ahead of the rear axle line.

A drag coefficient for the car would be instructive, as without, it's very difficult to appraise the merits, or not, of these 'supercars.' Deafening silence in the Age of Information.

Culturally the T50 is British complex.
However, the OX proves he can do simple if the program calls for it.
Much to admire.
Next generation of supercars will be all electric, he said so in the video. This is his swan song for the internal combustion engine I think.
The purity of not going with electric motor assist in the front keeps the ICE concept clean.

Gordon Murray is undeniably a genius, even though sometimes his creations seem to be out of context in a world full of mediocres.

most advanced aerodynamics
This means nothing to us without the context.
Exploding 1961 Redstone missiles had pretty advanced aerodynamics.
Category-5 hurricanes have advanced aerodynamics compared to CAT-1.
A pre-rupture, 95%-blockage Aorta, has the most advanced hydrodynamics of arteries.
An Oshkosh Defense' MRAP can withstand supersonic over-pressures of improvised explosive devices. That's pretty advanced aerodynamics.

Considering the importance that the number and size of cupholders has had for so long, it's amazing that efficiency of any sort is even admitted to exist.

Within the context of automobiles, aerodynamics has a pretty consistently understood meaning.

Cup holder-miles per gallon matter.

advanced aerodynamics in this story means complex, and that also means expensive.
Still, hard to criticize as unnecessarily so given the self imposed criteria and brilliant result.

Gordon Murray's blower
The latest ROAD and TRACK Magazine's cover story is the T-50.
1) the 8.5-kW blower requires 30-horsepower.
2) that's 22.38 kilowatts.
3) for a mechanical efficiency of 37.98%.
4) we can assume 100% drive efficiency ( direct-coupled).
5) if we're charitable, we could allow the Cosworth V-12 engine a 40% thermal efficiency ( we're not talking about a gen-3 Toyota Atkinson cycle ).
6) in that case, the 30-bhp, would require 75-hp worth of Btus to power it.
7) to get 33-pounds of thrust.
8) whether or not the fan is powered momentarily off the battery, to unload the engine, the energy shortfall must ultimately be made up from the gas tank.
