How do you make an LMP1 car from scratch?

[Music] building a car completely from scratch is one hell of an undertaking designing and manufacturing a rope cart will be tricky before over a car that's do 200 miles an hour and take corners quicker than anything but a modern f1 car we are at genetic HQ to see how they made this thing a full-blooded lmp1 car completely from scratch this is the Ginetta g60 LT p1 is being built right now but is gonna be going racing now this car can't quite keep up with the hybrid Toyota's without a bit of balance of performance but it's quicker around Silverstone than a Porsche 919 ever was so neither can't it's gonna hit serious top-end speed be safe to crash at those speeds create a shadow of downforce and also be able to race flat-out for at least 24 hours where'd you even start well I guess you start with a pencil and a bit of paper and these were the original renders for the p1 car and it's safe to say these are very different for the car ended up with but Alan you're a designer at Ginetta how do you start when your boss comes to you and says right they want to make a prototype how did you start the whole process so we start off and try and think of an idea or a direction for the sort of the visual style of the car so I've got various different starting points and it's a case really of just throwing ideas out there and seeing seeing what we like the look of and also see what you think do you need a complete understanding of the regulations or do you just go completely arty so in the initial stages you can pretty much do what you want always in the vacuum mind you always don't think well at some point this is gonna have to enjoy your car so it's a process of just starting off completely free and then honing in on on the the final design so we've gone from you could see the arty side and now we're getting stuck into the proper engineering so these are the cad models that create their own p1 car and is a very heavily regulated series so you basically start with a whole lot of regulation it's gonna be mode of hardpoints which is why these cars you could say look quite similar so ask your design engineer at Ginetta how do you create that first CAD model of a p1 car like you said we basically get the regulation templates and then we shrink-wrap our body work around those templates try and keep it as tight as possible and then maximizing their ergonomic games and that classic regulation of having a passenger seat in the car still exists for a limo doesn't it exactly yeah so if you look at our own p1 car today we have to make sure that the drive can get in and out both sides of the car with the cfd model so you're simulating a Windtunnel essentially what are you looking for in the CFD image we're just looking for a good correlation between what we think was going to happen with after if it's designed to what actually is happening in the real world so in this particular case we've got high pressure region on the rear wheel arch that we might not like because of the drug targets we've set okay so this is all air pressure yeah exactly high pressure in order to reduce the drug of the car we might want to look at modifying that shape and then develop the car further No we come to my favorite part this steel went on our model so this is a 50% scale of the real car and it's much smaller than that but I guess once you scale everything on the car don't buy that amount it's this size it was built by Williams to be simulated in the Williams wind tunnel and is literally the p1 car but smaller it has everything on it I expected it to be so much simpler than this just a kind of simple form of the rough shape of the car but it is the full car with all the aerodynamic bits on it it's got full suspension so you can measure pitch angles and everything it's got proper wheels on it so that these can spend and you can analyze the weight from the wheels and here you've got the brakes that can spin the wheel bearings all the suspension is in there back here you have all the engine and gearbox all Canada or 3d printed so that everything is there free to fully analyze the car it's incredibly cool and I want one so badly like Peter I'm slightly obsessed with this thing I've really wanted my front room but when people work at it it may seem quite an old-school way to go about things considering how far CFD has come so where is their still used for a wind tunnel model and terms of the phrase car engineering yes so obviously you see if these massively powerful and it's constantly evolving so there's lots of Technology lots of input into that so there's still limitations with it there's things that we can do with a want my model that we can't do in CFD well I guess you're finished with it so can we have it no it's it I'm having it first of Ginetta prides itself on designing everything borrow the G sixties engine in hose and the centerpiece of all of this is the carbon fiber monocoque and we've got one just the we're here it's an optimized include skeleton that really shrink traps our own the drivers and it's from where the rest of the own people and car sprites so this is where the engine attaches the twin-turbocharged v6 but that's not the only thing that makes this car fast is also all the rest of the bodywork now this is cool this is the lowest point on the car and you can see that it's been skirting along the track and hooking up the rubber from the surface I can look feet bleep off bits of rubber so we've got the thing that every lmp1 car has nowadays the shark fin we've got these side pods here we've got the face of the car the front nose here with the front lip and then the biggest die planes from canards I have ever seen on a racing car the rear wing which is the end of the shark fin on it not too big a diffuser but that's all dirt heated by the lmp1 rules and then if you come round here we've got the shark friend the rear body work for all liveried up it's the coolest Lego set in the world if you like racecar content then extranet eraser and Olympic champion Sir Chris Hoy has a new series on water trans which we think you'll be in see here's a quick clip

you like the look of that there's a link in the description below anyway back to the G 16 the car was put together of remarkably quickly and then we had access to an event that you'd never get close to in Formula One a private shake though testing everything from pit limiters to flatter accelerations the airfield tests give us a small insight into what the G 60 is capable of so I hope you guys have enjoyed seeing what goes into developing an LM p1 car Genet have been absolute legends giving us to sort of access if you liked this video don't forget to give it a thumbs up and also don't

After they're done with the wind tunnel they should bring that 50% scale model to events and let little kids sit inside.
