    My Dad runs a race team and prepares F1 cars for private clients. Today we got the amazing opportunity to see a 2000 Benetton up close, as well as have the amazing engineering explained by Big Kev! We shows the secrets behind the how F1 suspension is so light, how the gearbox is used to mount the suspension and why the exhausts are so curly!

      Big thanks to Ridge for sending me this wallet and supporting the channel! Here’s the site if you want to check them out! > ridge.com/DRIVER61 Who want's to see more of Big Kev in future videos?

      1. Blind Freddy

        Not if you keep screwing his knowledge about

      2. Thunder_Mouse_2014

        I LOVE the segment about the exhaust system!! I credit my late Dad for my interest in motorsport and classical music, though I never had the capacity to do anything with either. SO, when I was very young (1981-ish) watching some motorsporting this or that on T.V. with him, I saw the "bowl of spaghetti" pipes on the engine. I had been under the hood of the ol' '63 Chevy handing him wrenches a lot already and knew they were exhaust pipes, but Dad's manifold didn't look like that. I asked why they look so weird and he muted the T.V., took me outside and popped the hood and explained so that my 6 year old brain could grasp the basic why of it and why his was different, etc. What he didn't do is the typical dad reply: "Cause it works better, shut up or go play outside." The video did clarify some more like engine tuning that I never really got.

      3. Burnsy

        Just give your pop the channel, he’d do more interesting things with it than milk his fathers knowledge and act like he knows as well.

      4. neeklaus

        Let's see more of that Benetton! Get it on the track :)

      5. En Fuego Entertainment

        Interesting. Torsion bars were used on early tank suspensions as well.

    2. Gabe Shaw

      Your audio quality is terrible. Invest in some better equiptment

    3. 8power0


    4. David Allison

      Great video, what is that pleasant background music?

    5. Jonki Pastramki

      The unused acrylic supposedly manage because sky additonally colour via a talented energy. standing, cut anger

    6. vicpico1

      Hi! Notice in the picture, suspension is same as concept of Volswagen suspension rod or bar used in an vintage/old beetle.. lol. Thanks for sharing.

    7. Wyatt Friedrich

      Whoever produced this needs to be fired, too much misinformation.

    8. Alain Pascal

      But, but... You did not asked your dad the million $$ question about the exhaust system ;-) If the collector is the first restriction point, why have it at all? Why not remove it and have 5 separate exhausts on each sides? No restriction at all!

    9. Phil

      Host "observes" that the exhaust headers are all different lengths. Dad explains that they are, in fact the same length which is why they look the way they do. Host then reiterates that he thinks they're all different lengths. What a dope.

    10. I diot

      The front end is almost an exactly copy of a 1962 Jaguar E type which is on torsion bars and double A arms.

    11. CDR 011

      why are rear suspensions connected with that small bars between them?

    12. Kalder

      Is it just me or are there more people wondering how many YT'ers ridge wallet has asked to promote their wallet.

    13. spiKey0svetlana

      I pretty much like any mechanical video. But title is about torsion bars and you spent maybe 20% of the time on that subject. More on exhaust and packaging. Also you could insert an animation for better understanding. I still liked the vid very much! 👍

    14. Topi Rantala

      I am confused with that car number "7" and the driver info G.Fisichella and A.Wurz it should be different number or A.Wurz should be J.Button

    15. Snow Leopard

      the quality of the welds on those headers is surreal, given that inconel is so hard to weld and prone to cracking in the process

    16. Muhhamad Raza

      Btw, explosion is not the correct terminology. It's combustion. Very different as explosion is uncontrolled and high entropy.

    17. Peter Van den Meerssche

      Because it uses Renault 4 technology?

    18. Akademia Gitary - W Szponach Gitary

      I love this series

    19. Martin Comiot

      I love Scott’s enthusiasm, a couple of cold hours trying to remove the original torsion bars from a rusty Morris Minor has killed all mine off, thank God Lord Nuffield said no to putting them on the back and hurrah for angle grinders.

    20. Karl Schuneman

      What's old is new again, Chrysler used Torsion Bars in production in the 1960's and 1970's

    21. Aladin Gohar

      I could listen to your dad talk about cars all day long

    22. Michiel Noback

      Ingenieus ontwikkeling ?? Renault 4 had al torsie-staafjes. Toe nou toch !!

    23. bigjd2k

      Could they have variable primary pipe lengths to get a wider power band?

    24. Toms short movies

      Not everything on a racing car works well on a normal car. The front suspension on a Morris Marina was a long tortion bar design.

    25. Bill

      It uses torsion bars almost identical to what VW/Porsche used during WWII, never mind ‘modern’ cars. 😂

    26. J Garbo

      A coil spring IS a torsion bar, my good man. Coil springs are NOT compressed, they are twisted. My BSc MechEng was in Suspension and Transmission design.

    27. mikeleke0

      Nothing new here.

    28. odl21

      And a 1940’s Vincent bike has the engine as a structural member....

    29. odl21

      911s has torsion bar suspension until fairly recently

    30. Steve Kisinga

      mad respect for the content but man! the audio quality in that first part is just shit

    31. Paul S

      Oh and no way will I have a hard case wallet wearing the fabric out in my pants. that's the reason for leather wallets for 200 years. bad vid sponsorship

    32. Paul S

      title: why F1 cars don't use coil springs, then begins by showing F1 coil springs...

    33. 이승현

      좋은 정보 감사. Good 👍

    34. NickZero

      The rear is the only special setup. Its a cantalever system. The torsion bar setup is used on lots of regular consumer vehicles

    35. ACreamyMeme

      For anyone talking about this guy repeating himself about thedamn headers. It’s not always easy covering this stuff, as much as I love and have learned about cars I can say I still forget what VTEC means LOL, having this guy giving us a pretty damn good look at an f1 car and giving him shitfor repeating himself a few times is a pretty low blow. Go write up a script and do it better than he can then you can talk.

    36. Don Allen

      Torsion bars? Like Chrysler started using in the 50”s?

    37. stamps

      My 1967 Morris Minor 1000 had torsion bar suspension.

    38. Billy Tsik

      So, why not have a separate exhaust for each of the cylinder. You would end up with 10 tubes at the rear (would look VERY COOL) Why you need a collector ?

    39. Seung Yun Song

      Fascinating. Torsion spring at the front suspension is quite interesting since it reduces weight, cost, and packaging difficulty. But, how does the front suspension dampen the forces? I'd imagine there needs to be some dampening mechanism to prevent the front of the car from oscillating continuously. Would the damping due to tires and other components suffice?

    40. Claudio Campi

      Your dad is awesome

    41. Juan Colon

      whole video im like, stop touching the damn wing!! thats not a wall to be leaning on... 🤣🤣🤣 the disrespect is real

    42. Bruno Danese

      PLEASE make more videos like this

    43. Pasi Fsc

      I have 57 years old (this year 2021) car that has torsion bar front suspension.

    44. Nick H

      That would be sick to have a late 80s early 90s f1 car

    45. Gábor Miklay

      So, coil springs were replaced by torsion bars. If the 2000 Benetton's front suspension already used torsion bars, then I assume the 2009 Brawn's had torsion bars on the rear's suspension. Although, anti roll bars could still use coil spring. I think. So, no mystery if that suspension collapses.

    46. Roedor

      why not let every piston have it's own exhaust pipe? regulations? saving space?

    47. Aldas Grigaliunas

      "This car is 20 years old or so" - me thinking that looks awfully modern for something from 80s/90s!... "This is from early 2000s..." oh, now I feel old.

    48. courcheveller

      I have that F1 technology in my Renault Laguna street car.


      One of the 5 F1 cars is an F2 car 🤨>😕>🤯 This video shows that an F1 car is 4 wheels attached to an [engine attached to a tub], all connected together

    50. Mark Battista

      Your Dad has a great shop , Thanks for sharing it.

    51. Matthew Bridges

      “This is an early 2000s car”. But the tech looks like it’s from today. Insane minds.

    52. Dennis K

      All the exhaust pipes are cylindrical. The end of the exhaust pipe, though, is oblong. Does this restrict the volume of gasses existing this shape versus the cylindrical sections?

    53. Alistair Morrish

      The headers are the SAME length...listen to your Dad.

    54. patrick dean

      equal lenth exhuast

    55. patrick dean

      Oldsmobile tornados used torsion bar suspension in the front also

    56. sik59rt

      If they're using those tiny torsion bars now, does it make it difficult to select the spring rate you want ?

    57. Vortigan07

      Oh! I'd always assumed that his dad was......never mind, I imagine it's been mentioned before.

    58. Revener666

      Torsion bar springs are used on most trailers and caravans.

    59. Tetta Zwo

      There are two (rear) coils springs visible and explained...

    60. Brad Pittman

      I would say the exhaust system like that sweet as header is less about flow but more about scavenging with that collector. Just my 2 cents. Very cool vid.

    61. Snaker Stran

      My 20 plus year old Ford pickup had torsion bar front suspension. It probably wouldn't place high in F1, unless there was a lot of mud and snow on the track.

    62. Rhys Woodman

      "Tell everyone how it works dad" Proceeds to talk over his dad and tell us how it works.🤣

    63. Aaron Tate

      Kinda disapointed you didnt eplain the stressed block and gearbox casing being part of the chassis..

    64. Mad Irishman

      You don't have "explosions" in an engine. It's called deflagration. Detonation is exploding fuel charge that breaks things.

    65. Chris Garvey

      At 4:25 the son says, "If they were the same lengths they wouldn't come out, they'd all bang together." Wrong! They are all the same lengths. The pistons fire at different times and the exhaust pulses travel the same distances to arrive at the collector at different times. The pulses don't bang together. The pipes that start closer to the collector need to be curved to be the same length as from the farthest cylinder.

    66. Driving In Dreams


    67. sonicstep

      05:35, thinking of two cylinders, you'd want the gases from one cylinder leaving as tother is nearing the exit of the junction so that it pulls the newly emerging gas out.

    68. Neil Pincus

      A coil spring is just a very long torsion bar wrapped around itself. It still works by twisting. And your mixture should never explode. It burns in a very precisely controlled way.

    69. B Kopp

      Great video. Thank you. Merry Christmas to you and your family.

    70. cavagna

      “It’s loither”

    71. mikeyb byekim

      1:20 say whuuut..?? Is is is.... and and and.... funny but not bashing him

    72. Valleyboii818 Bikes

      You guys don’t even seem like you’re related like the way you guys talk to each other

    73. John Holden

      In reality the weight of the spring alone vs torsion bar is negligible. The question really is, where is the front shock or what type of apparatus is used to control jounce and rebound?

    74. Filthy Rethuglicans

      The magic happens under this cover i"m not taking off, instead, I'll draw a shitty representation. How. Fucking.Stupid.

    75. Daniel Oakfield

      I'd love to see more tech and real cars original footage like this one, and your father is a great addition to the show!!

    76. Conrad Paul

      VW beetle uses a torsion bar...

    77. M


    78. Tbest HotBowl

      Why not just, have 5 separate exit exhausts for each side? Maybe 3? Idk anything about this but seems like it could be just way lighter. Kinda like drag???

    79. Laura Gonzalez

      The cheerful ship anecdotally wave because shallot evidently curl circa a chunky postbox. victorious, proud gram

    80. Mad Rooky

      Wow, i only understood half of the technical terms in english, but i still learned a lot about the rear end of a F1 car.

    81. Mick D

      The wire in a coil spring twists EXACTLY the same as a torsion bar. Same principle, but merely wound into a coil to fit the design. This is why there are hard rubber/plastic SEATS at each end of a coil spring - it preventthje coil TWIST wearing out the metal in the arms, etc. Don't believe? Get a small coil spring and clamp the wire on one end. Now, compress it, watch the wire TWIST.

    82. 1D0N

      Next time, remove all cowling beforehand so we can see the magic. Advertisement seem to not match the channel at all. Nonetheless, some nice info here.

    83. Louis Mingham

      Wow f1 cars Technology is finally catching up to my 82 dasun truck it has torsion bars Suspension lol

    84. Timothy Martin

      Cool, I didn't know torsion bars twisted that way - there you go!

    85. Wetley Rocks

      I was of the belief that it was necccesary to keep the manifold tubes the same lenghth. As the firng oder is non-uniform, the manifold should be kept the same length so that each cylinder exhaust doesn't 'clash' with its neighbour.

    86. jlinkels

      You could not withstand the temptation to add background music although you were talking literally all the time, could you?

    87. Grissebassen

      Title: “why don’t f1 cars use coil springs?“ Literally the fist thing you see at 0:07

      1. scott walton

        this whole video was packaged in a clickbaity way. didnt even answer the question at the end about why they put the springs on the gearbox, its to keep the weight as close to center of mass as possible.

    88. Isaiah Prins

      The cool thing with f1, is that a 20 year old car is still packed with technology unlike a 20 year old American nascar

    89. DavidGP

      They ARE the same length. That's the whole point of it.

    90. gmofftarki

      So I'm still confused about the exhaust lengths. It sounded to me like your father was saying that the pipes prior to the collector needed to be the exact same length, which made sense to me since each cylinder (on one side of the bank, obviously) fires at a different time and thus the gases from that explosion would reach the collector at a different time. Meanwhile, you're saying that they're all different lengths in order to ensure that the exhaust from any given detonation reaches the collector at a unique point in time. Which way is it?

    91. Richard Black

      My old Renault 4 had torsion-bar rear suspension. There weren't many other respects in which it resembled an F1 car, though.

    92. Diego Bob

      Is the Judd v10 the original engine? Do racers of vintage F1 cars often swap out the original engines for something more serviceable with more spare parts, I'd be curious to hear your Father's insights. Also what other parts/electronics do they swap out/eliminate to make them easier and less expensive to operate.

    93. Burger Birger

      Who new that a F1 car had the same front suspension as an old Nissan Terrano😁👍

    94. solaufein

      Excellent content. Thank you.



    96. vishu sivaprasad

      Alfred? Is that you?

    97. Lozzie74

      A lot more in this video than just the torsion bar. Great stuff!

    98. trollnU

      It's a pressure pulse timing to keep every exhaust pressure pulse pushing and not interfering with the downstream flow

    99. Rem Sutton

      thanks, fascinating as always
