    Nobody beats it because nobody invests in beating this record , this is unrestricted not production cars so it's about spending a bunch of money but why bother, the returns are not quite there.
    Even this car is not built for this, just their Le Mans car slightly modified.
    BTW check out the straight , they spend about a mile at top speed, they really could have used some more power to gain a couple more seconds.

    Absolutely they needed a different gear. Looks like he was topping out at 228mph. I wonder if the 2020 roadster with SpaceX package and slight mods could go sub 6min.

    It's the same for Pikes Peak!

    When watching the video, you can see which gear is used and
    hear that the pilot is constantly changing gears up and down.

    Any EV without a gear box would certainly get a definitive advantage:

    - there is no gap of time between accelerating and braking (single pedal driving?),
    - and all the torque is instantaneously available as soon as the pilot presses on the accelerator.

    Yeah to some extent but Pikes Peak is an actual race with spectators, TV broadcasts and more substantial marketing upside, mostly focused on the US.
    Pikes Peak is tougher too, the air gets thinner and the ICE engine is starving, the downforce drops so quite tricky, especially for ICE.
    Edit: This is a hybrid and I imagine that's what the boost indicator is in the video so they do use the electric motors to cover the gaps.

    @ bcampbelllds
    The air is unlikely to last long enough.
    They would need to find ways to create downforce without drag, a lot of it. They are at least 2x heavier and their tires are gonna be lower perf. Plus the Porsche has that giant shark fin that is hard to replicate with the Roadster.
    Unlikely they have anywhere close to same power per weight ratio but likely they have much lower drag so they would need to try and keep it that way.
    I suppose fans under the car and a skirt on the side could help some.
    Maybe much lower latency active aero could be achievable but nobody sells chips with nanosecond latencies. The military could use more of those and maybe robots at some point in the future. Maybe SpaceX has some expertise in this area.

    In the end it's physics , you fight drag and inertia. Maybe the racing industry has been too focused on traction and that's not the only way to solve this with EVs. Maybe you can spend energy to more actively manipulate the air to lower drag and also take better advantage of the air when cornering (not through downforce but more like a plane), Inertia is a force and any force you can create in the opposite direction is a plus and the lead issue is how to do it efficiently since max power draw is the key constraint.

    Agree on the gearing.
    The Porsche 919 Hybrid Evo is a dedicated race car that is optimized for the track including factory team support.
    The Tesla Roadster is a street car that would require tons of modifications to perform at this level on the track.
    A better comparison to the 2020 Roadster would be the Porsche 918 Hybrid street car ... see my avatar :cool:

    The Porsche 919 Hybrid Evo is a technological marvel based on Porsche’s Le Mans prototype that won the 24 Hours of Le Mans from 2015-2017, but is now freed from anyone racing series’ restrictions. That means that its hybrid powertrain now churns out 1160 horsepower, its active aerodynamics produce over 50 percent more downforce, and weight has been dropped to only 1872 pounds.

    It was surreal to watch this lap record drop in person, because it came back around far faster than you expected any car to be able to do so. Once the car was out, there really wasn’t even an opportunity for a bathroom break unless you’re capable of speed-peeing in the building they had open for this purpose, which was a short walk from the 919's tent.

    Want another unbelievable stat? Today’s top speed on the notoriously dangerous, twisty Nordschleife was 229.5 mph. Makes you wonder where we’ll be at in another 35 years.
