Alpina B6 GT3 racer driven by autocar.co.uk

[Metti1984]

The Road Car has a 4.4 Liter supercharged V8... In the Sesson 2011 ALpina changed it to the S62B44 Engine from the the E39 M5 . But it's tuned to 530 hp

[cardude1992]

did he say it has the same engine as stock car? its a v8 moron!

[dilawer321]

Shame the road car isnt like this if it was bmw would be known for making the best road cars ever like the e30 m3

[MegaJaylen123]

that spoiler is so sexxi on that car!

[jackson3the3fishx3]

THATZ NOT A CAR THAT IS RAMBO ON 4 WHEELS

[Ouwtlawzzz]

12 civic fans

[3883624]

I want this minus the super low front spoiler so i can drive it on normal roads.

[mercracer24]

looks like the Eclipse from the Fast and the Furious lol

[erick4458]

How I can I get one of those cars?

[csbr75]

M3 GT2 looks slow close of this

[Groszka]

the noise is from no oil in gear box

[seroyer2]

Not to many supercharged race cars out there.

[carguyI3]

yeah, it's the tranny.

[TEFLONTHADON]

Look at the nurburgring times. I'll stop there before another argument starts.

[TEFLONTHADON]

But those few can't be touched by any lol.

[TEFLONTHADON]

Because there are a few that dominate this?

[raptor6400]

beautiful sound at 0.24

[TheLaneyzf]

listen to that tranny wow

[reconn08]

what is that tranny sound? is that shrill sound?  and what is tranny? transmission?

thx in anticipation :):)

[blueblue101]

@reconn08 yea it is the whine of the straight cut gears...... since many race cars dont ure helical gears

[reconn08]

big thx :)

[dewski1022]

thats not the tranny, that screaming you are hearing is the supercharger

[MickiDracing]

@dewski1022

The whining noise IS the gearbox, it makes the noise because it has straight cut gears.

[Arai4lpinestars]

My man,

Arai and alpinestars

=)

[NikkoThePinoi]

it sounds like 2 cars in one

it sounds like a muscle car next to a tuned import

[Imahappylittlewhore]

or a german car...

[dartasweideris]

well you are sadlly mistaking :)

[kornweasel]

Sounds like all hell is breaking loose when down shifting. Gotta love straight cut gears and dog'd transmissions.

[rootbeerfan6]

The announcer is like watching paint dry. Show some emotion you prat. BORING.

[venomspeak]

I wonder how the the car deal with the heat, one of the main reasons why superchargers are not used in enduro racing is due to overheating...

[bastec666]

Turbo chargers produce more heat than superchargers. Also, the centrifugal superchargers produce no heat, and have self maintained cooling, which means you get all the power you need and no bullshit. rather or not this BMW has one, I don't really know, but being a race car, it most likely does. Turbo's are used because of their high end use, superchargers gives you better low and mid range, which is used MORE when circuit/hill racing. With a turbo, you need a misfire setup to get proper use.

[venomspeak]

But the thing is with SC's, you use power to make power, wouldn't that parisitic loss of power be detrimental for race car, which basically needs to make as much HP as possible, especially if it has restrictors on the intake. Thing there is the Belt for the SC, which would or could snap in a enduro race. It doesn't seem to me that this Alpina would eat the M3 ALMS race for dinner. But, it reminds of the proposed M6 race car that was aborted.

[bastec666]

parasitic drain isn't really THAT big, maybe 20-40hp, but you also have to remember that its a BMW, they come stock with some nice horsepower and being a v6 it can get some nice power out of supercharger. also, the belts wont snap, if they did, our power steering and AC would snap as well, they last a good 60k miles if not more depending on what the belt is rated for, so its good to go. super charger is better because you get more low end which is needed when you slow down for corners.

[swingAE86]

transmission plus supercharger whine? :D

[hallin44]

Transmission is Dogbox'ed

[nickcars100]

@hallin44 semi semi automatic sequential....just that it is not a good as the others that is y u have to use the clutch on downshifts

[chopchx]

sounds lyk a plane

[Russell042]

Hate the sound of that tranny..But nice car

[an50331]

unfortunately ive seen plenty of civics with spoilers that big, lol.

[TheStallion234]

Haha yea but spoilers that big on Civics don't do anything, this one actually works

[Noobiewankenoobie]

Is this an electro-racer?

Sounds nothing like a V8...

[JayStiff]

That's the gearbox whining.

[IceAprs50]

thas the noice from the gearbox and rolling noices, probalbly supercharger too

[minimatsuiX]

what a gorgeous car

[SeigeCJ]

would be a good trackday toy!!!! :D

[jekyll1776]

Lots of racecars and Formula1 cars use Spur cut gears. Mesh gears (or w/e u wanna call them) are used in our general cars because they are quieter, Thats about it. Mesh gears do produce thrust though, so they would probably wear out prematurely in racing application.

[mhd86]

2:35 the car poops lol

[xSkullbusterx]

all u need is that flappy padle gearbox bu ferrari. Engages cl changes gear and disengages cl in less than 2/10 of a sec

[Janeshcw]

you can do more with a clutch - thats why race cars normally have a manually operated clutch.

[corotor12345]

last time i checked, the enzo's gearbox was a double clutch. if i'm right (maybe not but i'll explain anyways), then the enzo's gearbox does not disengage the clutch, shift and reengage. it simply engages one clutch while it disengages another. because 1st, 3rd and 5th are all connected to one clutch... and R, 2nd, 4th and 6th are hooked up to the other one. you need just to let go of one and clasp the next to shift gears.

[Karl21836]

you have to clutch when downshift?

Is this usual?

I´ve only heard of that 2 times before

[dgoretoy]

ofcourse u have to clutch while downshifting. the only time u dont use clutch is when ur going into neutral

[corotor12345]

it's counter intuitive that you have to use clutch when down shifting and not on the oposite event. but it really does have a reason: when you shift up using paddle shifters in a crash box, two things happen; the ECU cuts the throttle for a breaf moment, instantaneously eliminating load on the gears; and the hydraulic lever actuates the shift. it needs not using clutch because there's spare space for the selector teah to engage. downshifting on the other hand: (need extra space...)

[corotor12345]

ok so as i was saying: downshifting on the other hand demands that you use a clutch. because, unlike the engine, you can't really cut the torque the wheels are transmiting to the gearbox through the drivetrain. so if you don't use a clutch, the dog selectors cannot engage smoothly and you get that ((KKRRRR!!!)) that damages the gearbox. also, if they did engage, the fast over-revving of the engine would stress them uneccesarily. so we use a clutch to downshift on crash boxes.

[louisxiv42]

sounds like an airplane.

noticed the dash board looked stock.

[tranceme24]

alpina love

[fobos101]

it sounds like a bloody rocket is about to take off xD. after listening to that car you can tell it is defiantly a super charge because of that high pitched hiss as the air rushes in in.

[CurtMattack]

No that high pitched noise isn't from a supercharger it's from the straight cut gears the car has.

[iiredeye]

Nice one mate, i knew if I read enough comments on youtube I would find someone who knew what they were talking about.

[youlance29]

ZR1 IS KING!!!

[iiredeye]

@youlance29 Mate out of all the tens of millions of people commenting on youtube videos. You without doubt have to be the most boring, you have never to my knowledge posted anything either informative, or funny, or even slightly amusing, you are either very backward, or you just like annoying everyone so you can attract some attention to yourself because you have no friends or social life...either way I actually feel sorry for you. Good luck to you

[corotor12345]

no modern supercar uses spur gears.

[ftpaddict]

I'm pretty sure no modern car uses spur gears (with the possible exception of reverse gear)

[corotor12345]

yeah i know no modern car in general. but especially not race cars. and he said "straight cut" gears. and that means spurs. and we all know that spurs are very noise and can't handle much torque. thats why we use helical gears. also, the noise is NOT from the dog gears as some have said, even though this is a crash box. the noise is a mix of the supercharger pitch, the synchro's (it needs synchros, crash or not) and yeah, the helical gears sound too, just not as much as spurs.

[theundeadx]

i agree..

[MrMicTest]

dang man look how low that car is, and i bet that race car got a super stiff suspension, coz when it breaks it doesnt even transfer weight to the front. =]

[trxslashdriver]

since the weight doesn't transfer you would probably have to slow down a lot to turn.

[geeoffchin]

i love jet engine sound

[245thegreat]

look forward to the day graphics for games are as good as this

[ipodkiller6]

the supercharger sounds good though! lol

[04mustangsvtcobra]

that isint the supercharger. its the dogbox type of transmission that makes that whiney sound

[TigerSupercatE1]

listen to 1:05 and he says 'being supercharged'!

[04mustangsvtcobra]

well if it is supercharged, which it seems it is now that youve mentioned that little bit that i didnt notice, its pretty damn quiet. maybe its just droned out by the transmission. do you know what kind of supercharger it has? im thinking its a centrifugal supercharger of some sort

[player1vladimir]

it has a supercharger.

To be more precise its a radial supercharger (Nautilus-type compressor).

[ipodkiller6]

eh i don't like it

[zenom88]

me too

[NismoZtuneR34]

wow, that's a wicked gear change!

[alvisrepax]

Why is that guy having Force Feedback wheel as i do ? lol

[jo05dk]

Gotta love the HD quality:-)

It's always a little sad when a none-racing driver tests a racer. What happened? The other boys bussy with something else?

Nice car:-)

[tacosRdelicioso]

7th :)

[FordMustangGTR91]

nice car

[PATTYZ102]

So sweet

[XenoRacing]

I couldnt understand alot of what he said because of his accent =/

[starbury210]

it sounds almost like a jet from the inside lol

[danodien]

i agree

[TKMSeznam12]

Beautiful machine!
