[...] Last weekend, we were on hand to witness French racing driver Romain Dumas and car maker Volkswagen stamp their authority on all 12.4-miles (19.99km) of the [Pikes Peak International Hill Climb] course, destroying the course's existing record and setting the first sub-eight minute time in race history. What makes the feat even more interesting around Ars is that the car in the record books is all-electric, marking perhaps the first time in major motorsport that a battery electric vehicle has beaten the internal combustion engine fair and square.

In retrospect, if any car has an advantage at Pikes Peak it's the EV. The start line is already at 9,390 feet (2,862m) above sea level; the finish line is an even higher 14,110 feet (4,300m) and much of the course is above the tree line where there's 40 percent less oxygen to breathe. Consequently, internal combustion engines will lose power—significantly—as they climb the route, even with the aid of forced induction or crafty fuel mixtures.

But electric motors don't care about partial pressures of oxygen, and these will output the same power and torque whether they're at the top of the mountain or the bottom.

    The batts were charged from diesel generators. Carbon neutral, etc, but diesel. Excusable, being in remote place.

    OTOH, VW can do electric cars if they put the effort into it. And record breaking ones, no less. As posted above, they can also do hybrids, Porsche is same group.

    Put a monkey in their board room (another in Bosch's), trained to bite anyone that says diesel. VW seems to have a focus problem, not a technical one. Other brands my require similar measures, specially German ones. If board members don't change, use them to repeat the "diesel is clean" breathing test that hit the news months ago.

    Most brands should have started seriously moving away from "only-ICE" 10 years ago (cars, vans, trucks... everything) instead of some minimal tests and releasing their first public avaliable vehicles recently, some with pretty obvious self defeating designs (BMW i3? after Mini E test? WTF! you may dislike new fat "Minis", but at least they sold). 10 years ago Prius was already ~10 years old and it looks like pretty much any European compact car or station wagon. Newest plataform shares power train with other models that can be hybrid or ICE, so no excuse about being unable to fit into "normal" designs, Toyota can.

    If they are serious, they could even start good-will projects to retrofit old cars with electric systems. Currently only a few entushiast do that at their own risk. They would make nice city cars (some German cities want to ban diesels completly), and give cars with problems in the ICE parts some extra years of life, instead of going early to the junk yard. This way they would also show they know it's not just Recycle, but also Reduce and Reuse.

      I forgot, the PML Mini QED was 2006. Non VW related, other than using a Mini as base. It was hybrid, with better range in electric mode then Mini E, and even more by using the ICE. https://www.treehugger.com/cars/electric-mini-0-60-in-4-seconds-it-has-motors-in-its-wheels.html [treehugger.com]

      VW, F- on effort.

      All shareholders of car manufactures should ask for CEOs' pay to be returned since 1998. They clearly have no vision of future, not even caring about contingency plans, and just thought only-ICE could keep on and on. If they had started their own, Telsa would be have been a blip instead of hitting the news periodically and Toyotas would not be the dominant taxi car in some cities.

    Most electric records should not be surprising. All you have to do is look at things like power density/volume and power density/mass. Electric cars existed before gas engines.

    The only reason that gasoline beat electric was convenience in the way that most people used cars...well, technically electric cars at the very beginning were more convenient than gas, but as gas became more convenient it passed a minimum threshold.

      Exactly, energy density -- that is why the electric car can climb Pikes Peak once, then needs hours of recharge. While there is regen possible on the return back down the mountain (if the onboard electronics supports it), this probably can not be used to recharge the battery straight away because of temp limits (battery is very hot after the climb, have to wait for it to cool before charging).

      The ICE Pikes Peak specials probably have a lightweight, small gas tank with only a small reserve of fuel, it's racing, why carry extra weight. But, if the engineers were asked to double (or 10x) the range for a longer event it would cost very little extra weight or packaging volume. Gasoline has an amazingly high energy/mass ratio.

      Conclusion -- Range means something very different in racing where the powerplant is at high output much of the time. This is very different than "range anxiety" for normal driving at low average power.

      Looking at it another way, I don't think that Tesla Model S has done more than one or two fast laps of a racing circuit before it slows down with battery overheating (or runs out of charge).

          He built a trailer with two big reels of electrical cable and some electric motors to reel the cable back up. In between the reels sat an Allison V12 powered electric generator which poured the juice to the cables. His 4 wheel drive electric race car had 2 pickups underneath which drew electricity from the cables which were laid down on the race track.

      No need to pay off the timekeeper. VW has great engineers. They know how to build a mechanism into the clock so that it goes slower whenever a VW is measured. :-)

      More accurate to what actually happened, when the engine computer detects its on the Pikes Peak International Hill Climb via careful pattern matching of the throttle and break pedals, the dashboard clock suddenly changes to only count 40 seconds per displayed minute.

    But electric motors don't care about partial pressures of oxygen, and these will output the same power and torque whether they're at the top of the mountain or the bottom.

    There's usually a large enough factor of safety that it doesn't matter, but 40% air pressure means 40% cooling efficiency. For commuter car, who cares, but for a race car, its an issue. Just put on 50% or so bigger heat sinks and bigger fans and it'll be OK.

    I've occasionally thought about that for extreme overclockers, you can sell some dudes multi thousand dollar liquid coolers, so why not put an overclocked PC in a pressure chamber pumped full of hydrogen gas like the power plant alternators do for cooling? Just for the pure "holy cow" overengineering effect alone, that would be pretty impressive. Sorry guys I can't log in yet, the partial pressure of O2 in my pressurized hydrogen cooling case is too high, the rig might explode...

      from "overheat/slow down" for a car, you've suggested an exploding basement!
