Why Some Cars Are Faster Backward

Clarification: The discrepancy between the analysis and the actual power used was mostly because the analysis does not take rolling resistance into account.

About airshaper... Keep in mind their pricing. It's about $54 for a single run. Not bad, but if you're doing a lot of changes and re-running that will add up fast. If you want to use their fancy optimization system, which will run your model through a ton of times and actually alter the model to optimize flow, that's about $1080, wew. If you want a yearly sub, it's 10,800 (!!!), Woah. They also have a $325 per hour consultancy thing, where a person gets on the phone and walks you through your sim run and how best to alter the model for a re-run

there's a lot you can do to the front of the Jag that would be mostly invisible on casual glance: -small bellypan from the front bumper back to the front wheels, and air curtains inside the front fenders. (diverting air from between the two chrome sausage bumpers which could be a hidden duct) -block unused sections of the grille inside (blacked out, would be 'invisible') -naca ducts at the intersection of the front fenders and hood, just below the lights, for a high pressure relief zone. exit vents underneath. -controversially, bullet cap clear headlight covers. It would look like quad boobs, but you're a man so...moobs? and four, so moar moobs. I would say it would be sacrilege to mod a classic Jag but it feels like you might be a touch beyond being able to make that argument...

[@waveman1500]

The third car in the "aerofoil wedge" section is also an Australian designed and built car. Nissan Pintara Superhatch, built in Clayton, Victoria from 1989 to 1992. The "Superhatch" version was designed in Australia and actually exported to Japan because they didn't build a wagon version.

[@ronwalsh]

Another great video. Had a friend who was in college for aerodynamics and whatnot. He wanted to show that my MGB had worse aero numbers than his fiat spyder. Turns out the MG was cleaner going forward, and the fiat was cleaner going in reverse.l

[@mack_solo]

9:11 - this brings the memory of the Myth Busters episode where they were not allowed to name Porsche 928 so they referred to it as "this sports car" 😄 They also proved that it was NOT more areodynamic in reverse. Good show. Also the main reason wheels are not covered is servicability and assembly complexity - which why the prototypes often feature wheel covers that do not make it to the production line cars. Duesenberg Coupé Simone Midnight Ghost anyone?? 😉

[@MonoBrawI]

So how about directing some of that no longer needed air from the radiator out at a shallower angle in front of the windshield and/or to the sides behind the fenders? I suspect a lot of it used to escape downward behind the engine which could be blocked off with a sheet of metal. I think it would be really cool to improve on the Jag's aerodynamics in clever ways without hurting its looks too much.

[@pascalzarn8974]

Hi Matt. Julian Edgar has amazing videos on improving the aerodynamics on cars. One of his latest videos is about the drag from cooling and how porsche reduced that drag by forcing the air in front of the front wheels instead of just.... Out.

[@anomamos9095]

There are a couple of period correct not too ugly things you can bolt on to improve the drag coefficient possibly. First a stone/bug shield in front of the windshield , this is a small strip of plexiglass mounted just in front of the windshield at an angle to deflect anything that might damage the glass up over the roof. You see them fitted to big rigs sometimes. Second is the trunk rack that they bolted to the top of the trunk. You could design one that looks classic but works as a spoiler. Additional changes. Blocking off most of the radiator and ducting the engine bay air into places where it will improve aerodynamics.

[@petercrowl9467]

Deflect-a-Shield! Originally developed as a gimmick to sell to the rubes but later discovered to actually work at keeping bugs off your windshield.

[@TheOystei]

I wonder how much difference having the sides of the engine bay open makes. In racecars they put huge efforts into getting the air from the radiators/intercoolers out from the engine bay, not just for cooling but also for airodynamics (makes the wall less of a wall and more of a air duct).

[@alext8828]

My fluid dynamics prof used to say; "If you push fluid out of the way, something's gonna wanna fill the void. It could be the wing of a plane or the ass end of your car." He was very smart. I'm not so much.

[@BramageDained]

When a bunch of guys got together and did actual windtunnel testing of the 240/260/280z years ago, they found out the stock bodied car had a drag coefficient of .471. The real alarming bit was 367 pounds of lift on the front wheels@120mph.

[@Mastermind12358]

Bought a old 80s boxy mercedes once (W124), was very surprised to know that they were extremely aerodynamic (with the sleekest models being only 0.26 drag co) Interesting stuff.

[@robertkb64]

There’s a trick you didn’t mention for radiators - the drag is based on frontal area, While heat rejection is is a function of surface area and and fresh-air airflow - but it’s a decreasing multiple so you can have a large radiator at an angle to the incoming air and have the same heat rejection as a smaller radiator directly facing the airflow. You can see this applied in F1 cars (or the Veyron - I assume the Chiron does it too), where each car will have numerous relatively small inlets with diagonally facing radiators, reducing the frontal area of the car. This is because the heat rejection of modern radiators doesn’t scale well with increasing airspeed but scales better with increased surface area. You’ll find the same principle in PC CPU all-in-one water cooling units, where you get a dramatic increase in cooling performance with a larger radiator rather than increased fan speed. I’m sure someone has the equations for this, my expertise is in application here - I’ve never had to actually solve the math in advance for this.

[@RoamingAdhocrat]

This is also true of most aircraft, which is why tailslide manouevers are usually banned. The forward drag coefficient is so low that when you reduce it further, by going backwards, it actually becomes negative… and the aircraft just zips into the lithosphere before the pilot can react.

[@PixelSchnitzel]

You absolutely need to turn the interior 180° now, work out some legal (but not visibly obvious) lighting and make that car go backward full time. You can leave the steering on what is currently the "front" axle; just reverse the direction when you work out the new linkage. It'll just take a little getting used to. I'll be watching next week's episode for your road test of this. 🙂

[@Jonathan_Doe_]

You could take the air from underneath backwards jag and duct it up through the rear mount radiator. This would make the air at the back break away more smoothly by partially filling the aero vacuum the vertical surface creates.

[@eb110americana]

Adding something like a spoiler lip at the back would indeed be sacrilege on this Jag, even if it helped aero. But there is one big option that would retain the overall shape while aiding aerodynamics: Hood louvers. You'll have to run more simulations to find if placing them across the top or sides (or both) will be most effective at alleviating low pressure zones and turbulence in this area. Not only would it improve aero, it would aid airflow through the radiator, and because there is no engine in the way, a secondary surface could be built to guide air upwards an out. In side view, this surface could better approximate the sloped nose of something like a Prius, but would simply exist as ducting below the louvers, and behind the radiator, so you would never see it.

[@halnywiatr]

And here I was thinking this video was going to be about 2 stroke Saabs and Trabants driving in reverse with four gears. I was wrong.

[@eformance]

When I was young I noticed that if I stared and defocused, I could see the turbulent dust/air that cars carry with them. It only works if I relax and not focus on anything. Also, the 87-93 Mustang GT has a cd of .36-39 😁

[@Anya-Prime]

Aw I was really hoping you’d find a large enough parking lot to get the Jaaag up to speed in reverse and try to compare it to the consumption going forwards. Doesn’t need to be highway speed, but at least the motor should be capable of that. Regarding the aero design notes, I’m pretty disappointed that automakers haven’t yet taken advantage of EV packaging to make extremely cab forward designs that actually have all the right shapes in the right places. The closest is stuff like the ID.Buzz and Canoo but they have a stubby front end and a far away windshield for cargo reasons. Now I want to see a Buzz with kamm tail and some cD numbers. I’m excited to see how they can innovate when they move beyond expected shapes in car design. I guess stuff like crossover coupes and ultra efficient designs like the XL1, lightspeed one, and EQXX are a step in the right direction by why stop there? Also side note, I really liked Jason Camissa’s ELI5 explanation of the coefficient of drag - he said it’s like how much smaller an object looks to the wind. So a car twice the frontal area but half the cD of another look the same size to the wind.

[@hannahranga]

well, now Matt, here is an idea. make front wheel coverings that move with the wheels, so when you go straight you get the full benefit. at low speed, like pulling into parking space drag is not your problem. does not even have to mount directly to the suspension, maybe just put something that pushes the covers when the tire gets close, maybe springloaded? or a stepper motor with some programming? if it really makes a difference it should be totally worth it on trips. Much of the rad could be sealed off, too. no reason to invite a ton of air under the hood for no reason.

Someone did that back in the 30's with a sedan showing how it was more aerodynamic in reverse. I love the guys with those little Jap cars with 3 cylinder motor and 6" exhaust pipes with wings that look like something from a 747.

Probably 50 years before Matt popped into existence, tests were done on cars from the '20 and '30s, and it was discovered that cars were more aerodynamic going backwards. The resultant 1934 Chrysler Airflow was an abomination...styling wise.

[@TassieLorenzo]

It looks alright to me! It seems like it was mainly the front they improved on the Chrysler Airflow, the rear looks pretty conventional for a car of time, it slopes down but too steeply to avoid uncontrolled flow separation (it's neither an extended gently sloping tail, nor a Kammback which is a gently sloping tail but cut off for practicality of vehicle size).

[@Cloxxki]

If you make a roll cage ocvered by a glass dome, the dome can be made to look "black mirror" while actually offering a great view out. The rear crash structure gets an under the skin upgrade. No problem as the original bonnet will offer a huge boot in the now back.

@03:08 doesn't the air go through the radiator grill down and out? I'm uncertain if it's the worst offender there.

If it is closed off to keep water and debris out, then extending the V shape in front might help.

The best thing about the E-Type 2+2 is that it is easier to fit taller drivers comfortably into one than a E-Type FHC or OTS. This wouldn't be a problem for a reasonably sized person like yourself but those of us who were born with a little too much stature REALLY appreciate that sort of thing. That's the main reason why I purchased a Chrysler PT Cruiser instead of a Toyota Matrix.

Take the body and spin it around, built to drive backwards at highway speed with 200 miles of range so you can flash your high beams at the f150s tailgating you.
