- In this short episode we look at how the SPOON motorsports hardtop for the Honda S2000 vehicle changes the aerodynamics. How does it affect the lift? the drag? the general aero forces? Find out in this episode of automotive aerodynamics!

love the explanation, especially when there are lacking videos like this for the "aftermarket" parts.
Thank you for your good information and the informative yield for this useful research 👏🏻
Very thorough explanation of your findings! I'd be extremely interested in seeing how the OEM soft top affects to drag and lift compared to common hard tops (OEM and Mugen). Many s2000 track guys ditch the soft top for hard tops to gain performance. I'm curious to know if it's worth losing that convertible feature and added cost.
It makes sense to use a hardtop for aerodynamic efficiency because a soft top like on traditional convertibles flaps and moves around at high speed which creates a lot of drag and negatively affects aerodynamics. For the same reason why the top performing sports cars and supercars are all hardtops.
It make me think about what BMW done with e30 M3, can be a nice project to compare standard e30 with M3
how about the S2000 with OEM hardtop + OEM rear wing? Would be interested to see how that compares with the Spoon hardtop
any chance you could also compare the Mugen hardtop?
What music do you use for the videos, it reminds me to the GranTurismo menus so much!
Awesome info Graham! I've been wondering what the aero looked like on the OEM hardtop since the first S2000 video. I got a burning question on the OEM hardtop--is this possibly a LEGITIMATE application for roof mounted vortex generators or a turning vane? I want to keep my OEM hardtop, but want to reduce drag as much as possible--would you expect keeping the flow attached would achieve that? Would it even be possible to keep the flow attached with the sharp rear windscreen without causing more net drag, using some aerodynamic device? In my case, I'm running a very efficient wing at a very low AoA well into clean air, so even if I was producing lift with the car body, I'd think I could cancel it out with the wing with a lesser drag hit...
+Chris Wiita This remains to be investigated, however my guess is that the rear angle is too great due to the short trunk. Vortex generators are most likely not enough to keep the flow attached and will add drag themselves, a turning vane may keep the flow attached but add more drag than it saves. To give you an idea of when these devices are useful, some STI and EVO's used them to positive benefit, but they had shallower rear ends. If you are serious about finding a solution, shoot me an email and we can talk more.
S2000s have bad under body aero, feels like a parachute in the back with the rear bumper... You'll see a lot of the with their bumper chopped on the bottom! Would love a video, just discovered your channel!
Hi there,
I'm really enjoying your videos, thanks! It's nice to be able to see what's actually going on with the airflow. Very informative.
I was wondering if you might be tempted to do a similar video with the BMW Z3 and the M coupe version.. Asking for a friend.
The Z3 obviously came as a convertible but also as a hatchback/shooting brake in the Coupe and M coupe versions. I would love to see the difference in the airflow for these two models and also if adding a slightly larger roof spoiler to the M coupe would improve, or worsen, the aerodynamics at all?
something like the AC schnitzer roof spoiler.
thanks
Does the mugen hardtop have similar advantages as the spoon hardtop?
Awesome. Thank you. Ill exactly asked for this ;)I hope you make someday an AE86 hatch with popups and without ;P
+Shadowdarknessone (with TRD wing ;) and popups open and closed )
Do a porsche or 350z in relation to wing behavior as seen with spoon hardtop..
Hi Graham, I'm curious to see how the flow characteristics in terms of drag and lift are affected to an OE hardtop with a GT wing with height of at about the roofline. I'm positive that DF is created but I'm more interested in how much more or less efficient it would be compared to the Spoon top with a wing.
hey man I see you found his channel too, he's has great aero stuff for us car nerds.
+skatebrian624 yeah man, I really like his stuff. The hydrogen blast is pretty close to wind tunnel testing. the only thing I wish he could replicate would be the flow underneath vehicles. that's where air dams and splitters and ride height should all play into effect.
Wow, great channel. I didn't see a Fiat 500 buuut if you could that would be interesting to show for me at least ;0>
Please look at the password jdm flat underbodytray diffuser. Will this help even without a wing?
Please you can look the aerodynamic from the bmw e36 LTW
Many thanks
Couldn't a 2nd gen CRX shaped hardtop be even better than the Spoon Top ?
What system are you using to simulate this data?
