what would you do if someone rang andasked if randy pobst could lap their mclaren p1 around mazda raceway laguna sega youprobably say yes and how bout a porsche 918 spyder and ferrari laferrari joinas well that's exactly how we arrived at thisday with to the fastest most powerful production cars at oneof the world's greatest race tracks yeah two what happen to the laferrari well while mclaren was happy to send technicalsupport porsche supply of 918
ferrari refused to grant permission forhot laps and data acquisition to the owner of the laferrari we hadlined up a truly unfortunate decision the the day is noless special as the p1 and 918 represent the futureof the sports car both are completely carbon fiber from tub tobottom panels both have small displacementhigh-revving v8 pact between their passenger compartment in rear axles they both use use twin-clutch transmissions carbon ceramic brakes to and active aerodynamics and active aerodynamics
they both have around 900 horsepower but best of all both are plug inhybrids with real ev modes and now we get to find out what they'lldo it the same track on the same day with the same highlyskilled driver this the manliest thing i've done in my life an effort to level the playing field we fueled both cars at the same gas pump tire-rack supplied factory spec rolling stock the p1 got the most aggressive tires owners can get from thefactory pirelli p zero trofed r and they cameheat cycle
the michelin pilot sport cup 2 is theonly tire option for the 918 and while these were source from tirerack porsche opted against heat cycling the production car lap record here is 1 minute 30.97 seconds it will fall today but the question isby how much randy set that time last year duringbest driver's car with the pre-production 918 and its familiarity with that 918 means he'll lap this 918 first to acclimate to the radical speedthese cars generate
alright randy you know the 918 you've had the lap record in theprodution car lap record with the car here and we're gonna see if we can beat it so this compared tothe p1 their both carbon fiber tubs bothv8sthis one is naturally aspirated but butt flat plain crank like the p1 887 horsepower combined wowthat's crazy this is nuts just saying the number i'dlike blows is my mind hybrid on the rear axle of course butthe big thing about this is the front
axle is electrically powered so there's about 600 horsepower comingfrom the v8 and the rest that's all coming from the electric drivetrain big difference between the p1 is this has rearsteering too so actually gonna help you stabilize the carwith at the higher speed corners now you probably a member the last caryou drove here pretty vividly as how fast it was yeah that makes a striking impression carlosyeah thing is an animal on the straights actually handled extremely well wingworks and has some downforce
ya the big difference on this one isthis one has the optional magnesium wheels that you get on the vice ofpackage and they should lighten up the car quitea bit were on break into absolutely cuz a lotta breaking is juststopping the moment on the spinning wheels yeah pilots sport cup 2 like on the lastone this is a good tire thirty seven hundred pounds and changeso little bit heavier than the mclaren lap thats on account of the power frontaxle battery yes this is a little
like the sophistication the hybridsystem is what makes this one so interesting well the all-wheel-drive should be areal advantage especially with that kinda power going on nine hundred so so you cana beat that record be ready i'm ready man let's do it i'm heading down pit lane at mazdaraceway laguna sega i'm in a brand new porsche 918 making 887 horsepower that more
gas horse power than the carrera gt had and more electric horsepower than thepower and the original 930 turbo in one car gotta love that electric motor driving the frontwheels the gas engine driving the rear and we're exiting turn two yeah babe 9000 rpm there's instant torque response from the electric drive
listen to the 918 howl the noisesor just fabulous in turn five all stability controls are off you know i like it all natural just me and actually the 918 for me is faster that way it's like throwing off the rings and giving me all you got up into turn six this is a faster corner the all wheel drive is a big advantage for coming off a turn the power is incredible its more than any race car i've ever driven and i have been racing for 30 years people way more
the wing is working the car has good aero balance just dig out of turn ten turn eleven tight second gear just drive off with the all wheel drive i wonder what the p1 gonna be like itstwo wheel drive this is four wheel drive could be a real issue trying to get that power to the ground i've never driven it we'll see the p1
also is quite a bit lighter that's going to be the advantage lightweight verses all-wheel-drive interesting in the break zones the 918 is extremelystable with the braking power it varies a little bit in other words you hit the break hard you don't get your full g immediately late in the break zone the ceramicbrakes heat up enough regenerative system is working at full max and the breaking is increased
quick steering response and it's got a little entry oversteer see that the 918 gives the driver some options carving through six the steering is spot on i mean that porsche steering we've known and love it's here it's here in the 918 the managing configuration gives it a really quick and easy turning it's lower than normal it's still the surgeon's scalpel the drive
shocked is superb it's firm but too much porsche has found a really fine balance between the ride and the handling even on track bumps don't disturb the 918 excellent accomplishment
man i hate this car because i'm spoiled now i want everything to run like this the 918 is a extremely sophisticated extremely powerful hybrid supercar i mean we use to think hybrids were toyota prius 50 miles per gallon
but guess what how the hybrids are fastest cars on earth using the electric motors augment some fantastic race to rod power plants and now for the 918 hot lap presented bytire rack that's a new lap record at laguna secaa shockingly fast performance it beats the pre-production 918 fromlast year by 1.07 seconds but combing through thedata to find out why i will have to wait
there's another car to lap it after the 918 finally mclaren p1you haven't driven this car right yeah finally i've heard so much so like the 918 all carbon fiber also flat plank crank v8 small displacementtho 3.8 liters but twin turbo the great equalizer yes and it makesmore power to so total 900 plus horsepower they say 905 908who cares your over 900 might as well be a thousand right that number is amazing a but this is rear-driveonly yes all that powers is gonna tothe two rear tires okay that'll be interesting
yes and as you can see just by lookingat it here it's quite a bit lower and the wings quite a bit taller sowhat's really aggressive super-low if the 918 has the reallyinteresting stuff going on the front axle this is a really interesting stuff goingon with the suspension it doesn't have any roll bars this doesn't have a locking differentialokay it's all controlled hydraulically throughcomputers which do all kinds a math and just ride height to account for all thatstuff was actually in race mode
words two inches lower than the normalright height its i'm slam i shocked at how low it is this is the cruiser mode this is ahard park mode you couldn't drive through city streets like this i guess so see that wing chai wing sittingback there it looks like two wings it is i thinkthere are two elements in that thing and its active so it's gonna adjust toslowing down during braking to move around you'll see the rear view mirrors do allkinds of things and their claiming like
1300 pounds of and how the downforce at like 150 mph it looks like a radical piece i'm not surprised this is 300 pounds or so lighter than918 and a little bit more powerful so i'mcurious to see what you can do with it the p1 is going to be interesting because that's a lot of power through two tires in and open differential that they controlthrough breaks yeah very interesting stuff i'll seeyou can do with it heading out on the track in a mclaren p1
torque i love that sound when i pop off the gas ihear the turbo pop mclaren's gotta couple of turbos pushing it to a v8 flat plain crank it cooks that power feels so good it'sgoing to be hard to go back to a normal car look at that thing ok that run was from 90 to 130 just like that time it amazing car
the acceleration rates are just mind blowing it's a whole another category of car and it climbs this hill up into the way of the cork screw like no othercar i've ever driven here it doesn't feel like a hill amazing it's like a rocket launch straight up acceleration the p1 feels stronger thanthe 918 but not coming off a corner see the two-wheel-drive that can knock you sidewaysat this kind of power
918 digs off with all wheel drive this mclaren is a wilder car than the porsche 918 it takes everything those pirellis have to give but sometimes it's just too much for two wheels to handle and you know what that makes us be want a real driver car you got to be careful with that gas pedal
like spider-man with great power comesgreat responsibility you got to roll it in there you go keep it hooked up breaking a strong but there's a lot of avs intervention the porsche has smoother breaking down atturn two takes a lot of steering the mclaren is stable on the way in is very firm i can feel the front end bouncing a little bit even on a race track like mazda
raceway it is very slow it is stiff very race car like mclaren feels light at the rear sterling accurate of course but youneed a lot of it you need a lot of steering input to get the car into a corner and it's well damped the reflexes are quick cat like like a race car
yeah like i said this mclaren is it driver's car ripping the gears i hit the drs button it drops the wing down top for top speeds on the straights thats a pretty cool featureit's reminiscent of formula one mclaren feels better on the straights i'll tell you that in race mode it is on the ground low ho ho good aero dynamics for a street car
strong rear wing very powerful porsche has a big advantage coming offthe jump because of it's all wheel drive the mclaren is more stable under way in the corner than 918 the 918 is more stable on the way outof a corner than the mclaren the mclaren has a very race feel that is credible satisfying porsche is a bit little refined it's more a all around car
listen to the wheel spin we're digging for traction in the 918 you just drive off the corners in the mclaren your on the edge of traction all the time mclaren fells quicker and fastercorners it's got ton of down force the 918 feels quicker in the slower corners where the all wheel drive is a big advantage and i am frankly not sure which one is gonna turn a quickertime at mazda raceway laguna
seca and now the p1 hot lap presented bytire rack the p1 is radically fast we hear wheel spinevery single time randy flies over turn one he loves the car but is it faster thanthe 918 the mclaren people are surprised theporsche people are surprised everyone surprised the mclaren peoplechange tire pressures an engineer says the pirelli take 4 or 5adjustments before they settle the p1 goes out for more laps and comesin for more adjustments
we install another set of trofeo r after that more laps more pressurechanges the p1 goes no faster then it's 130.71 lap set on the first set of tires the p1 incredible power to weight ratio showed up on all the straights it did a 155.5 miles an hour over turnone which has to be a record for a car onstreet tires the 918 gain an advantage in major braking zones especially in toturn two the corkscrew
and turn 11 the data shows the 918 entering break zones consistently laterand harder than the p1 which is something randy notice from theseat of his pants what aided the 918 most was its ability to power out ofthe low-speed corners harder while the 918 accelerated out randyhad to work to p1 hard for traction despite the work he love the experience holy macro wow that now that's areally different personality from that love it but man you gonna be onit you're using right here in there in the rears are right on the edge of their grip and pulling gears
it's a driver's car yeah this hot lap battle was always goingto end with a winner and that car is the porsche 918 it's cleverelectric assisted all-wheel-drive system and low speed cornering proficiencygave it the advantage it's an incredible performance from anincredible car while there's undoubtedly some disappointment walking this maclaren remains just as wonderfulit's still the quickest accelerating car we've ever tested and faster than any other production carever lapd here
randy enjoy driving or two there may bean eighth tenth of a second gap between the 918 the p1 but there's a three second gap to thenext fastest car at this track and focusing too much on the smallenough time that separates the 918 in the p1 almost as a disservice to theiraccomplishments here we have two plug in hybrid streetcars with ev modeson street tires posting lap times that would qualify the mid pack at most sports car races here they jumped
far ahead of other normal fast cars atthis track seemingly leapfrogging a few years ago ourdevelopment technological improvements mclaren and porsche have leapt farahead into the future blazing a trail for everyone else tofollow
