    Faster than an F1 car: Porsche is breaking records with the 919 Hybrid
    It no longer races, but Porsche's tribute tour for the race car is
    serious business.
    JONATHAN M. GITLIN - 4/9/2018, 10:51 AM

    For a few glorious years, the "P1" prototype class in the World
    Endurance Championship (WEC) was the coolest thing in racing. Audi,
    Toyota, and Porsche built all-wheel drive hybrid racecars, each with
    more than 1,000 horsepower, each capable of running flat-out for 24
    hours or longer over distances it would take an F1 car an entire season
    of races to rack up. But Audi and then Porsche both withdrew from the
    sport, their highly successful—but very expensive—racing programs casualties of Dieselgate. Porsche pulled out at the end of 2017 after
    winning almost everything there was to win with its 919 Hybrid. But
    before the company puts the cars into the museum, it has some unfinished business, proving just how insanely fast the 919 Hybrid really is.


    Porsche is taking the 919 Hybrid on tour, but the plan is to do more
    than just show it off to the fans—it's going for records. The first of
    these has already fallen. On Sunday, April 9, Neel Jani set a new track
    record at Spa-Francorchamps in Belgium, home to that country's annual F1
    race. Jani lapped the 4.4-mile (7km) track in 1 minute 41.770 seconds,
    12 seconds faster than the 919 Hybrid's previous best time at the track.

    Let's put that in more context. In last year's Belgian Grand Prix, Lewis Hamilton set a new lap record at Spa during qualifying with a lap time
    of 1:42.553—0.783 seconds slower. To make this new feat even more
    impressive, Porsche set that time in weather barely warm enough for the
    tires to switch on—the ambient temperature was just 12 degrees Celsius
    (53.6 degrees Fahrenheit) compared to 17 degrees Celsius (62.6 degrees Fahrenheit) for the F1 event that took place in August.

    The powertrain of the car—now called the 919 Evo—was mechanically the
    same as raced in 2017. It's a 2.0L turbocharged gasoline V4 engine
    driving the rear wheels, coupled to a motor-generator unit (MGU) at the
    front axle and a second energy recovery unit that harvested electricity
    from the exhaust. Both energy recovery systems charged a lithium-ion
    battery, and that energy was used by the MGU to drive the front wheels.

    But the technical regulations of the WEC imposed some limits on the cars
    in order to keep performance within a range the organizers considered acceptable. Among other things, this included a fuel flow
    restriction—1.784kg of fuel (2.464L or 0.6 US gallons) a lap. What's
    more, the hybrid systems were limited in the amount of energy they could
    deploy each lap. In 2017, this was just 6.37MJ.

    This is how fast it really goes
    Now that the 919 Evo isn't racing, Porsche doesn't have to abide by any
    of those restrictions. It's still running the same race fuel, but new
    engine management software has bumped power on the internal combustion
    engine from 500hp (373kW) to 720hp (537kW). And with 8.48MJ now coming
    out of the battery, the hybrid system is 10-percent stronger at 440hp
    (328kW).

    Porsche's aerodynamicists have also been given a free hand. There's a
    new front diffuser and a much bigger rear wing. And both are active,
    which means they can change profile to minimize drag on the straights
    and maximize downforce in the turns (two tweaks that are good for lap
    time). Porsche says the 919 Evo has 53-percent more downforce and is
    66-percent more aerodynamically efficient compared to the bodywork it
    used in the Six Hours of Spa-Francorchamps in 2017.

    Other changes to the 919 Evo included stronger suspension wishbones and
    new power steering to cope with the higher cornering loads, a new
    brake-by-wire system that added some more yaw control, 86lbs (39kg) of
    weight reduction (total overall weight: 1,871lbs or 849kg), and new tire compounds courtesy of Michelin that maximized grip.

    According to Stephen Mitas, chief race engineer for the 919 Hybrid,
    letting the car off the leash was a dream come true:

    Having developed, improved and raced the car for four years, the guys
    had a very close relationship to it. We all knew, no matter how
    successful the 919 Hybrid was, it could never show its full abilities.
    Actually even the Evo version doesn’t fully exploit the technical
    potential. This time we were not limited by regulations but resources.
    It is a very satisfying feeling that what we’ve done to the car was
    enough to crack the Formula One record.

    If you want one last chance to see the 919 drive in anger, Porsche will
    be bringing it to the Nürburgring (including a demo lap on the fearsome Nordschleife) on May 12, then the Goodwood Festival of Speed (July 12 to
    15) and the Festival of Porsche at Brands Hatch (September 2), both in
    the UK. The final outing will be at the Porsche Rennsport Reunion at
    Laguna Seca in California (September 27 to 30).

    So long, and thanks for all the laps.

    Porsche
    Toyota also took the cuffs off
    There are still quite a few opportunities to see the last of the P1
    hybrids race, however. Audi and Porsche might have pulled out, but
    Toyota Gazoo Racing is still taking part in the WEC's "Super Season,"
    which gets underway next month at Spa and continues all the way through
    until the 2019 24 Hours of Le Mans. The US round will be a 1,000-mile or eight-hour race on March 15 at Sebring in Florida, the day before IMSA's 12-hour race takes place.

    This past weekend, the teams of the WEC took part in their annual
    preseason test at Paul Ricard in France. And there, too, we got a
    glimpse of the raw speed of an unleashed factory hybrid racer. On the
    first day of the test, the Toyota TS050s were blisteringly quick, with
    Mike Conway setting an overall fastest lap of 1:32.662. That was five
    seconds faster than the non-hybrid, privateer P1 cars that make up the
    rest of the class for the Super Season and four seconds faster than the
    last time hybrid P1 cars tested at Paul Ricard.

    For a day or so there was much consternation over the speed
    differential, until Toyota explained the real reason: on Friday the cars weren't bound by fuel flow or energy limits, and the team turned
    everything to 11 to stress-test a new cooling system. Unlike the 919
    Evo, Toyota was running with homologated bodywork and on its regular
    tire compounds.

    SPLIT OPINION
    I LOVE that they are going to blow away F1 records. But a little sad
    that it's not with bodywork or the engine how the cars raced. It shows
    the technical potential with non-standard aero, but the claim that the
    car crushed the F1 record kind of has an asterisk.

    It's technically correct, but by the same token, if F1 cars weren't
    bound by their own restrictions, they could be a lot faster, as well.
    It's not the most meaningful comparison, agreed.

    Given the restrictions on F1 cars, it isn't terribly surprising that
    it's faster than an F1. I mean, F1 cars from decades ago are faster than
    the ones today and there's only so much you can do with 2.4 liters.

    Today's F1 cars are the fastest of all time on most tracks, at least in qualifying (they aren't that fast in the race because of the onerous reliability and fuel use requirements that force teams to clamp down on
    engine power). Their top speed isn't the highest ever because of how
    draggy they are, but the sheer amount of downforce makes up for that.

    That said, I'm really hoping the next-gen engines in 2021 will be a
    couple hundred HP more powerful. I think racing is at its best when the
    power to downforce ratio is maximized.

    On the one hand, the car should be difficult to drive. It used to take
    cast iron ... attachments ... to take Eau Rouge/Radillon flat.

    On the other hand, when the cars are so aero-dependent that they can't
    follow closely, the racing suffers.

    But, we all knew that.

    The fact that the LMP1 Porsche was heavily modified to a point that it
    was no longer an LMP1 car should be mentioned earlier in the article.

    Also, the record was set outside of the race - Hamilton’s 2017 car would
    be even faster - much faster if it was run outside of a Grand Prix race weekend. Mind, F1 temas were limited to 3 power units last season so
    they couldn’t run on full power - they need to last.

    Essentially, we’re comparing a rule-compliant car time setting a lap
    time under race conditions against a one-off attempt by a car designed
    to break record.

    And still.... the time difference is fractional.

    But if the point of F1 racing isn't to design prototypes that go as fast
    as completely possible (within some safety and maybe size or toxic fumes constraints) then what is the point of it?

    It is, ostensibly. But then the richest manufacturers just wreck
    everyone else, and it gets too dangerous, so they do things to limit
    speeds and manufacture regulations to limit cost and force competitors
    to be more similar so the races are closer and more interesting to watch.

    It’s like, NASCAR was technically supposed to be about racing stock
    cars—as in, normal street cars. But after so many rules and changes to
    make them uniform for more interesting visual spectacle, they are less
    like street cars than this LMP1 prototype is.

    F1 is the quickest FIA sanctioned series. If you try to build car that
    isn't bound to any restrictions, sure you can go faster. For such a
    respected company like Porsche I would have been surprised if their cars weren't the quickest.

    I never understood the insistence of race organizers to neuter their

    the car can consume per lap or what shape the front hood has to be.

    Races would be a hell of a lot more exciting if you did away with all

    Real world is a bit more complicated. You don't want cars to go so quick
    that drivers aren't able to control them. You also don't want to end up
    with boring races when you know the obvious that cars that are quickest
    in qualifying are quickest in race, because that's boring. You want to
    make it possible to overtake You also want to have series that is
    affordable. Then add politics within F1 to the mix and you end up with
    heavily compromised rules.

    I've never really understood that particular argument. I'd think that

    just how far they can push their machine in given conditions. I can see

    I don't think you can really design a course where a mistake would risk
    death. Formula 1 is too good for that and safety has to come above all
    else. There's always a risk, but I'd prefer if the risk were a
    spectacular crash rather than one of death. I still remember the TV
    images watching early in the morning when Senna had his fatal crash.
    Don't want to relive that or Suzuka 2015.

    If you have cars so fast and powerful that only the best three or so
    race car drivers on the planet can control them you won't have much of a
    race.

    Also, you will not be able to rein in race engineers or drivers with
    some nice words.
    If car and driver made it last race week the engineers will push a
    little further this week. After all, it worked last time so how is a
    tiny little improvement going to hurt this time? Same goes for the drivers.
    You need hard rules or you're going to have a bunch of dead drivers on
    your hand.

    What F1 needs, more than anything else IMO, is a set of aerodynamic
    rules that allow longer close following and more overtaking when pulling
    out from a draft. Their tires still get wrecked from low down force
    understeer when following closely for any period of time.

    The DRS flap and zones were an attempt to increase passing but it does
    not tie directly to drafting and is not helpful enough on all tracks.

    My first reaction is: they have probably done it with some sort of a
    cheating device.

    They would have to reduce the front wing, allow ground effects, and let
    them re-add the diffuser.

    That should reduce the front grip making the cars corner slower (most
    passing happens in the breaking zone) and reduce the loss of downforce
    from turbulent air going over the wings (since the car can generate more downforce from the ground effects). Beyond that you'd have to look at
    changing the rear wing design so that it leaves a larger hole in the air
    giving the following car a bigger draft.

    Do you know how downforce vs dirty air compares with F1 cars and the WEC
    cars? Is there a lot more passing in WEC? I don't watch F1 anymore but
    it used to be that you couldn't drive more than a few laps close enough
    to pass, waiting for a mistake, because the dirty air would cause your
    car to slide around and wreck your tires.

    I am also a non-racing person. But one thing that I find interesting is
    that these artificial limits could really push the creativity envelope
    for the teams involved. You can't just toss the biggest engine in there,
    but rather have to have a more efficient one. Or more reliable one. Or
    do something creative with the aerodynamics that don't violate the rules
    but still give you an edge.

    I like the idea of that being a potential outcome. But as I mentioned, I
    don't follow motorsports at all so I don't know if this really comes to
    pass or not, but if so it would be an amazing plus side to all of the restrictions.

    You know, F1 cars could be faster without the f1 restrictions also..

    As Fangio said quite a while ago (paraphrased): the point of F1 is to
    win races in the slowest possible time.
