Fastest racing car design

[DaveKillens]

why you say open wheeler? Aren't they very poor on drag?
What are the advantages of an open wheel car?

The exposed wheels of a formula car are very high drag, to the aero, they are a handicap. Remember, as a wheel spins, the top of the wheel is moving backward relative to the car motion. So an exposed wheel in a car going 100 KPH is doing 200 KPH at the top of the tire as far as the aero is concerned.
Enclosing the wheels in bodywork protects from this condition, as well offering additional downforce by proper design of the front fender.

also with a turbine if you take your air in under the car is becomes an amazind sucker car

ok, let's start with restrictions: all downforce must be created from the air-flow, not "generated" by any device, such turbine, fans...

I was just wondering about how fast could be a prototype or F1 without restricted aero...

still fast enough to make the driver black out

i belive it was cart had the problem a few years ago of drivers blakcing out in corners

Fastest race car....

Let's start by the fastest street legal car: McLaren F1. No ABS, no power steering, not even power brakes (all these to make it light), composite body, 627 hp, 1290 kg, fan-assisted diffuser. 240 mph

Fastest car with an engine you could actually buy at your car store: Nish Motorsports Streamliner small block Chevy engine. 345 mph. They are going to try again in August with a blown fuel engine, which I recommend for your efforts.

Fastest car on pistons (FIA engine world record holder, Group 1): Spirit of 76. 410 mph

Last piston car to hold the land speed record: Railton Special. Tires with threads of 0.5 mm wide (it is not a typo, the width of the lead of a pencil), 180 kg aluminium body, 3.200 kg total weight, 47.000 cc (yes, forty seven thousand), 2500 hp engine. 394 mph, 1947.



Fastest car in the world: Thrust SSC. 35.000 G's resistant wheels, no ground effect (hahahahahaha! ground effect... good one!), absolutely minimium frontal area achieved by burying the frontal wheels under the engine cover and having the steering mechanism on rear wheels, active suspension to control attitude (just one degree of nose tipping and the car would have flown), 110.000 hp total thrust engines. 763.035 mph - 1227.99 km/h

Question raised to a member of Thrust SSC team: "Now that you've gone faster than the speed of sound, what are you going to do next?"

Answer: "Well, there's always the speed of light."

First time in history a shockwave formed around a car:

It would have to be a Honda Prelude with a 4 1/2 ft. wing, a loud annoying cat back exuast, 19 inch rims so you can see the stock brakes behind them, oh yeah and paint the rear drums red.

i though that was taken over by the Vayron? or even the Kernecesecssghhhhhsshh (top gear spelling) they do 250 ish

Dauer-Porsche Le Mans is the fastest legal road car with 402 kph an 0-100 in 2.6 sec

1030 kg, 2994 cc Porsche flat 6 twin turbo, 730 bhp @ 7400 rpm, 5-speed manual RWD

I meant racing cars, no street legal cars...

I started this post because I became so annoyed about all that "hanged clothes" growing each race along the silhouette of an F1 racer: I'm talking about all that small winglets, fins, splitters and vanes that, imo, greatly disturb car appearance and give 0.01% aero gain.
Engineers however, have little to create: all aero is so regimented by FIA regulations, that they are forced to focus on the very very details, "wasting" a lot of work for a little gain in aero efficiency, that btw appears crucial to win.

I think car body should pursue a low-drag theme, with very "clean" bodywork, while downforce to be provided by unrestricted front, rear wing + undertray.

BTW: can anyone explain how moveable side skirts worked? I didn't quite realize that...

Here you can see them on Villeneuve's Ferrari. They are made like very wide and thin brush (flexible) and attached longitudinally on the left and right side of chassis. I'm not sure but I think apart from being adjustable I think skirts were also "suspened" on springs that were pushing them down to the ground because they were getting worn-off from friction (stand to be corrected).

Basically, all skirts were movable or at least flexible because you couldn’t run car with rigid skirts without huge drag due to friction (not to mention bumps and vibrations).

On the pic above they are raised because car was used to compete in acceleration vs. jet fighter so no downforce was needed.

Just thinking, lets say we are to make a raceing series as suggested in this topic. For sake of argument say they were to be used only on today's current F1 circuits. Possibly include circuits like LeMans or Laguna Seca etc into this equation.

Surely there wouldn't be ONE possible way to get the fastest cars. For example, Ground Effects and moveable wings, active suspension, multiple wheels, TC, LC, CVT, Turbo Engines could all be used.

But surely there would be different idea's or variations in how to use these. Some may want multiple wheels, others want just wider wheels? Or do you use Turbo or Supercharger? CVT or a twin clutch box (altho maybe CVT is a better choice anyway), Deisil or Petrol engine...Biofuel? Fuelcells?

Moveable wings? or none at all JUST ground effects? with ground effects you cant hae a diffuser can you (because ground effects essentially turns the whole underside into one big diffuser) so maybe a team wants moveable wings and a difuser but not ground effects.

Could you imagine just how varied the competition would be?!

You should slap in a couple of ovals, if you are talking fastest race cars. And ¿why not? one or two drag strips and maybe some dirt tracks... This way you could essentially end with four different types of cars. You know I believe cars have to adapt to tracks, so if you want different solutions, give’em different problems to solve...

On first day, God created the track.... on sixth day he created Ferrari, Peugeot, VW, Citroen, Porsche and McLaren, and then, satisfied, he took a day off. This very same day, Cadillacs, Mercedes and BMW were created by a demiurge. (I am just joking, just joking, M3_lover)

Chassis: nanofibre monocoque tub w/ engine as fully stressed memeber

Aerodynamics: Full sidepod ground effect with ajustable composite side skirts, no upper body wings (inefficient). For low speed tracks like Monoco, possibly a sucker fan (Weight penalty). Fully enclosed body.
*Either run the rear tires really wide to allow full length side skirts inside the rears, or run side skirts outside the rear tires. (it would look like the silk cut jaguar)

Suspention: Fully active suspention. ABS. Traction and launch control. Corner by corner on the fly adjustment. Huge brakes.

Tires: BIG, BALD, BEUTIFUL, and enclosed.

Engine: I would go with a turbocharged rotary running on a alcohol/nitro mix.

Trannsmisson: CVT holding engine at torque peak/hp peak rpm.

How about a March 817 with an enclosed cockpit? I'll go find a picture, but essentially a Formula 1 car with enclosed wheels.

So what are the restrictions so far? are we looking for a track car or a dragster, aand are we looking for it to be road legal
(remember sleeping policemen so adjustable rideheight would be needed to get over speedbumps)
