I just crunched the physics of thrust for my hovercraft design. It doesn't look good. if we have 130 hp powering the 4 vertical thrusters, we can only support 250 kilograms... a 130 hp engine weighs. 12kg only... but the battery would be 50KG... that's 62 kg for the 4 vertical thrusters... if we want 130 hp for each direction the thrust the engines and power supplies would weigh 186KG max, add in a 70KG driver = 256KG = can not get off ground and we don't even have a frame yet. D: Bad news for hover car fans. 
We can, of course reduce performance... but who would want a 50 HP 200KG car than cant go up hills or accelerate more than about .15 - .25 of a G. lol it would be about the same performance as the stock '68 fiat 500 with CH tires and a 200KG Ballast XD
@LosCules24SFA I have designed a Hover car.
But prepare to be disappointed; it looks really really cool with more vents than a Saleen S7. 
But it drives like a '60s Fiat as I said. lol
Guys, I know the hovercar thing didn't really work out, but I think some of its concepts; (My side vents specifically) could fit in really well
@Nessy Do you think you could try to add a side vent into your awesome car?
zomg IDEA!

On the previous page; I use arrows to point out each of my 12 vents. XD It looked so hilarious I also posted it on the meme forum XD lol. and anyways I sketched a 2J inspired concept that I came up with after designing my hovercar.@sk8er913 where's your sketch lemme see it
this is my new concept(Active Electronic Aerodynamic Babysitter). Please add it too your cars if you think it would fit, improves cornering capability by up to a lot regardless of what tire compound you are using. Ask me if you want to know what it would do to your design, please keep the holes at a minimum of 24 inches, the bigger it is, the more effective it will be.
ex: It its powered by a 130hp electric engine and battery, it has 2 holes in the side that are both 28 inches wide. it will improve your cornering by up to 250 KG. ... If you are driving a Nascar.... that's .16 more Gs of cornering force!
But more importantly; it helps you keep it straight to avoid sliding.

I dont think PD will apprrciate a hover car tho. Why not make it like that old chapparal race car with the propellers facing backwards and all (like the redbull too). If a hovercar is in there they might need to rename it to the real flying simulator XD. Good idea tho.

No worries we're not going to make a hovercar

Just had another idea. You can tell me to stop lol
Thank you LE-Composites Evo.
These ducts underneath the car...
...direct air out from below it...
...and through this outlet.
It effectively makes the whole vehicle into one big downforce-generating wing. Not to mention that it can be exploited to provide radiator cooling, or to feed air to a turbocharger.
Doesn't have to be on this scale and in this exact configuration (the vents could be placed on top of the car before the engine, if we follow the mid-engined route), but just another design feature that shouldn't be to taxing on the efficiency.

Nice! I was thinking about having the exhaust shooting out of there but man that is too awesome. Plus it would help cool the two stroke!Just had another idea. You can tell me to stop lol

But we have to make some adjustments cause of the MR, maybe between the two sides of the engines

What about driving style? I know we won't know how it handles for sure but do we want it to be a fun, enjoyable car to drive or something that can go as fast as possible round a track? Not a race car but like a super fast track car (like fxx, zonda r) or are we going for just a fun sporty car, like say a 500 abarth? If it's already been touched upon then my bad

Most likely something similar to a Lotus Elise. Small, fun and fast.

I was thinking of a shape that was somewhere between deltawing fxx-k and elemental rp1. Powered by a 90degree v4 aluminium block with magnesium case to reduce weight positioned behind a 1 seat carbon-fiber tub. exhaust ports feed electrical generator instead of turbo, and intake is force-fed with an electric blower (like the f1 electric turbos). 1 generator sits on the rear axle which also feeds during breaking, but doesn't act as a motor for the rear axle. there are 2 sets of batteries for this car, the first, smaller battery is powered from the alternator and the exhaust gas. This battery runs the e-turbo and the cars normal electrical systems. the second battery is more of a conventional hy-kers, with the front and rear wheels charging a larger battery during breaking, with the front generators able to act as a second 100 hp motor for the front wheels, making it temporarily awd during acceleration. the overall shape of the car is almost like a motorcycle in the middle, slightly wider than the deltawing in the front, but as wide as the fxx-k in the back. bridging the wide width of the rear wheels and the extremely narrow cockpit are wings which force air from the bottom of the car into it, around the intakes/through the intercooler then out the back creating downforce. in addition to this is a large rear wing which can lower to become flush with the car. I believe that with a 1.5 liter v4 with electronically controlled boost which will exceed 50 PSI, (imagine a cross between the 919 hybrids and the rc213v honda and an f1 turbo) we can produce a 500 hp @ > 10,000 RPM. Using Carbon-Fiber, graphene+titanium and graphene+magnesium we can definitely keep the weight close to 500 kg. I've broken the weight down as follows:
Tub 60kg (Elemental RP-1 achieved this weight with a two-seater)
Hy-Kers 150kg with battery (10kg more than LaFerrari)
8 Speed Sequential 90 kg (same as ZF 8HP70)
Engine 50kg (10 kg more than the DIG-T R from the zeod rc)
Body/Misc components 150kg (Weight budget to keep under 500 kg total)

@TacoParty I don't want to hate on your design but what if the front and rear ends were the same width

@wvmgmidget I'm not against it, I just wanted to reduce drag like in the Delta. Front and back being the same width (maybe still a touch shorter in the front) would look baller and be easier to control though.

You guys have some nice ideas floating around here, just to let you know. I'll be happy as long as it's slightly driftable and quick around a track, which shouldn't be a problem with a little bit of a suspension setup.

Electronically controlled suspension in the wheels recharges during compression and spends energy during extension to keep the car firmly on the road. Bose claims that the current draw on the car is a third of running the air conditioner, and so will instead be powered by the ERS batteries. The rudders on the front of the car are controlled by small actuators, while the rear rudders are fixed to maintain stability. According to Brundle, who in part helped design the williams active suspension, active suspension would be such an advantage it could make formula racing boring, but in our VGT it'll feel right at home. That with the low-weight, the active aero rudders
and spoiler and the hybrid awd and we might have quite a beast in both the turns and in the straights.

Man you stole my idea about the suspension

- Toronto
I'm trying to incorporate as many ideas from this thread as I can. I was imagining a car that because of a steep power curve, 8 gears, light weight and active suspension can be short shifted and driven like a daily, then you step on the gas, get all the power surge from the front wheels and crazy boost pressures in the back and drive it like a formula car.

Also, because the active suspension would be able to keep the car low with much lift off or bottoming out I think it should maybe utilize more advanced ground effects, like that EVOs diffuser. We could be looking at a car on par with the 2x and the x2014 without using ridiculously complicated technologies.
