Detailed Results From Pikes Peak Indicate How Sparse Oxygen Helps EVs Beat ICE

It’s obvious that without oxygen there is no fire and internal combustion engines will not work. The higher above sea level, oxygen become more sparse and in a race to the clouds, like Pikes Peak International Hill Climb (up to 14,110 foot / 4,301 meters), this hurt ICE and in turn helps EVs a lot.

ICE is just not working in its optimum range, which explains why EVs almost won this race event last month, while at the same time in other types of races there is still some technological progress needed.

Across the 12.42-mile course, there are four sections. In the first two, the overall winner was quicker than the fastest EV by over 5 seconds and almost 4 second respectively. But in the higher two stages, everything changes, as Mitsubishi MiEV Evolution III’s driver Greg Tracy was faster by nearly 3.5 seconds and over 3 seconds.

Additionally, Hiroshi Masuoka was faster than the overall winner in second part of the race. Results for Nobuhiro Tajima probably aren’t good for comparisons because technical problems slowed down his E-RUNNER.

We have turbocharged piston engine airplanes that can develop full power at 20,000 FT and higher. I am doubting that this is an ICE handycap.

But airplanes take this issue into consideration and are designed to adapt the fuel mixture according to the altitude. I doubt any of these car ICEs do that but they might start doing it to improve performance on hill climbs like this.

Not a completely valid comparison. Different drivers will factor in how they run the course.

Spec9

Certainly that is a factor but there are 3 different EV drivers there and two of them were slower at the start and faster at the top, so it may be a valid observation.

Spec9

Another factor though is the fuel weight . . . as the ICE cars near the top, they will be lighter since they have burned up some of their fuel whereas the battery EVs will be just as heavy as at the start. But this is probably a pretty minor factor since I assume that ICE cars fuel up with just enough fuel to make the run and battery EVs use batteries that are just big enough to make the run.

Hey I breathe oxygen, along with most of you, not addressing the aliens who may or may breathe it, so quit combustion of it in ice’s.

From my understanding it is the lower pressure at higher altitudes, not less oxygen, which causes the loss of efficiency for ice.

Aircraft are travelling at much higher speeds and therefore a much greater volume of oxygen is available too them.
