- Let's have a closer look at the Lamborghini Huracan GT3 EVO2.
How did Lamborghini change the street version STO for a better GT3 car?
Why did they change to a roof scoop?
How does the shark fin work?
Let me know how you like both models in the comments below!

Could you do a video regarding the electric motor (or other electrical components) technology in high-end motorsport such as F1 with MGU-K or Formula E? Are there any exotic technologies not currently present in high-end customer cars?
The MGU-H isn't and will most likely never be in production cars.
MGU-H will be available in the next Mercedes C63 AMG with 2.0l 4 cylinder M139 engine with (supposedly) 476hp:

But since the use case between customers and track is always very different, electric components are fine tuned or even designed differently too.
That's cool, I can't wait to see it.
I thought we'd never see it since even F1 has decided it isn't worth the additional cost and complexity.
Can you do a video about gt3 technical rule,and how far the stretch between street and race car
I love the idea of homologation specials, like the M3 or Lancia Delta Integrale way back.
I don’t think it makes a lot of sense for 6 figure super cars tho. Why make a special Huracan instead of creating a new, exciting successor that incorporates all these racing features from the beginning?
Cost to create a new chassis from ground up when BoP will just hold it back. And EPA regs, STO was probably the last hurrah for the huracan before the successor replaces it just lime the amg gt blsck series or shelby gt500 or dodge demon or 765lt etc
Quite sure lexus is doing that right now :)
why only 2 min. 15 min pls
deine videos sind geil, aber für mich könnte da noch VIEL mehr über aero physik rein. ^^
ansonsten weiter so
What an amazing car.
Ok this is where the GT3 regs confuse me. I hope maybe you can answer this as i havent been able to find an answer anywhere online. So they needed to make a road legal variant of the huracan with a roof scoop and shark fin to be able to add it to the GT3 car. That makes me think of the question; how far can u go modifying a GT3. Like everyone does different front and rear bumpers and extended wheel arches. So i ask, what areas of the cars bodywork can u touch and how far can u change it. Ie: splitter design, material, length, complexity. All rules say its down to homologation but whos making the decision what can and cannot be homologated, whats the box all must work within?
The FIA GT committee (a technical group made up of most of the competing GT3 OEMs) ultimately decides if the final product made by a manufacturer fits within the intended rules of GT3 build regulations - there's no 100% hard and fast way to make a GT3 car due to the differing models used and variety. That's who makes the decision on homologation. The overall external silhouette of the car must match the reference road going car made in production level volumes - hence why the STO is the reference car for this EVO2.
Basically:
Wider fenders etc are standard most OEMs take it to the maximum width allowed (2050mm).
Base chassis - no changes to the main section (centre) and rails but race specific front and rear subframes are allowed. McLaren is unique as the car is built around a carbon tub. Effectively chassis rails, sills, floor pan, suspension turrets*, inner arches, screen pillars and bulkhead/firewall are incorporated. Any changes to these requires a waived/approval from the committee - * the Lexus RC-F GT3 has one of for its front suspension which has lay-down shocks.
No Electronic suspension trickery or AWD
Mods allowed to mount transaxle gearboxes (access, mounting frame)
Splitter and flat floors are open - depends on how the manufacturer wants the car to behave. The old Reiter Camaro GT3 had no flat floor and neither did the last generation Aston Martin Vantage V12 - they were aimed at Amateurs. There overall length dimension though for the reference car but longer = less nimble. Now all cars have flat floors
No tube-frame cars allowed - "GT3" cars that do - Ginetta, Radical etc are not given international homologation but a national one (limits their entry to the big events)
Material - most cars have CF body panels and parts - some have titanium roof (watch it flex when people do a victory stand on it). The reiter Camaro had ABS plastic panels/bumpers for cheaper operational costs.
There's a pretty standard overall set of equipment/build formula that goes into a GT3 and its configuration - but mostly its all about the car making it into a performance window set by the FIA so it can be BOP'ed easily. Most manufacturers can make a complex GT3 car but because they are customer cars - how much money is an owner prepared to throw at maintaining it with exotic parts? How easy is it for regular race mechanics to navigate? How durable will it be? How consistent? How drivable?
Of the modern GT3 cars left only the RC-F stands out because in Toyota Racing Development President Doug Wilson's words: "Lexus RC F is a dynamite sports car, but I’ll be candid and say that it’s not a GT3 car - we’ve done a bit of a Frankenstein to raise the level of performance” because it had so many concessions after failing to meet the FIA performance window twice. The rest of the GT3 field though is pretty level in terms of build quality.
@@Kurz_Weber ok thank u. So in theory they can go absolutely bananas with the underfloor and aero bits as long as it is within the rules u stated but no one does that for cost to design it and for people to afford it i assume
@@zombiegutkill8043 Pretty much. There a limit to space you can fit the floor aero in - for instance for Front engined cars, the transaxle gearbox limits the position of the diffuser tunnels. The Bentley GT3 (2018+) had massive tunnels sculpted around the gearbox, where as the Porsche had small one due to the engine/gearbox locations limiting the height. The other side to why OEMs dont go crazy is: Aero cars are harder for most amateur owner/drivers to extract speed from the car - and because GT3 is supposed to be customer racing based there's an issue if you make your car too aero heavy - nobody will buy it. And even if you make the aero great and the car corners fast - BoP will ensure you have no speed on the straight!
In essence - most GT3 OEMS now aim for drivability and performance consistency - reliable engine power in a multitude of atmospheric conditions, tyre wear stint life (how to maximise the prime operating window of a tyre) - things you can't BoP as they are dynamic and fluctuate.
👌👌👌
1:55 the single front Carbon bonnet of the road going STO has no benefit to the GT3 EVO2 model - which as you can see in the picture at 2:14 has a multi sectional front section (separate bonnet, front bar, wheel cowlings, splitter etc.) to minimise cost to operate for owner/racers who would find replacing the entire front very expensive after contact - this affects the cars $/km operating expense. Audi R8 LMS GT3 does this the best with a proper multi part front that requires smaller individual panels to be replaced minimising overall replacement costs.
The STO also mainly takes the roofline intake/fin cues from the Super Trofeo EVO (mk I) which debuted back in 2017 and has a central engine air intake directly under the engine cover - that car would be the first genesis of the visual and performance upgrades seen on this GT3 EVO 2 model. 1:27 the scoop intake will have cooler air but is effectively the point of access for the mandated air restrictor for BOP so it will not really have the benefits of RAM air stated as the cars overall power is still capped. I agree that the lower over all entry air temperature will help make the performance more consistent and reduce fluctuations, particularly during endurance races in hot environments such as the Bathurst 12 hour (40 degree C temps on race day).
could u do a video on indycar aero ?
They put a fake scoop on the road car so they can put the real one on the race car?
Cool
That's cheating! :)
@@docmccoy9813 ;)
@@docmccoy9813 not cheating if rules allow it
Why doesn't it have a rear wing similar to that of the Audi R8 LMS Evo2?
And also nice video!
Not an expert but the Hurracan has a different aero balance to the R8, as well as suspension geometry and engine tune. So the R8 wing might not be the optimal design for it
@@AKK5I i think he did a video of the benefits and drawbacks of the audi style wing. The gains r probabaly super small and for the extra support material to have it go around the back, up and over, and back down onto the wing is gonna add weight but thats why the wing here has cut outs to help avoid cross flow separation. Good think to think about it just because 1 car does it and just because its a new thing doesnt mean its the best way or only way to do it
Stephan Ratel is laughing. While crying.
This makes me wonder, similar to the Ferrari 296 GT3 car, could the changes be for the sake of better equipping the car for the challenges of the Le Mans 24 Hours race?
No. The Huracan GT3 was already a well developed product prior to Le Mans (ACO) announcement they will take on GT3 cars. One EVO kit for the Huracan was already released for the 2019 season and the EVO kits extend the car's homologation typically by 3-4 years - hence the new one for next year.
An exception to the EVO cycle is Mercedes AMG who have lobbied to extend the current Homologation of its one-and-done EVO kit as they don't see the value in doing a second one just to charge owner/operators to buy something for on a platform they will phase out soon.
So with BOP, how can the design of the car still give an edge over other manufacturers? More areodynamic stability? More setup choices?
Yes, and better reliability (lower intaketemps, better brake cooling etc.), better tire management, better weight distribution etc.
Wider setup window, easier/more predictable to drive, more adaptable to different driving conditions, more efficient, faster/easier repair time, extra durability + reduced service intervals, work tires easier, more aerodynamically consistent, reduced cost for parts and maintenance
One example is the air intake: BoP just tells you which restrictor to use but if the air that is going through the restrictor is 6 deg colder, you have an advantage.
