Sounds exciting !! like double-six feeling
for novice drivers,
Mazda gives them a rev limit of 7000rpm.
(787B is available a rev limit of 9000rpm.)
but..He couldn't detune his lust,so reved up to almost 7300rpm.
4 rotor
![[HD] Greatest Hollywood Car Chase of All Time - Bullitt (1968)](/img/n.gif)
The 787B is probably the most important Japanese racing car ever, because it is the only Japanese car to ever win the 24 Heures Du Mans - the Le Mans 24 hour race, which it did in 1991. This proved to the world that the Japanese can compete at the highest level of motorsports - and win (because the Le Mans in that era was arguably even more important and mad than the Formula 1). The mighty Mazda's technicians famously said after winning the race that it could easily go for another 24 hours......
::: HammerStudiosGaming ::: Hi! Did not expect to see you here!
The screams of a 4 rotor is harmony to my ears
One of the coolest Group-C, or GTP cars ever!
Having seen this car in action back in 1991 at Le Man flying through the 5 km Hunaudieres-Straight will make anyone flinch/cringe due to how load it is. The thought still sends chills down my spine!!! =)
A fantastic and amazing piece of Japanese engineering.
鳥肌がたって、次は感極まって涙が出そう・・・
I saw this very car win at Le Mans in 1991, never has one heard such an awesome noise as this car makes!!!!
Amazing video!
The 787B is by far, the best LeMans car of its age! It combined speed and engine credibility.. Very very beautiful with amazing rotary sound :)
Its amazing that such a light car can put down all that power too. Incredible.
I love the sound of the Engine and the Exhaust pipes,
its like a music to my ears...
Imagine driving this car for 24 hours in the Le Mans race with that speed and that sound ; ) It did win the le mans in 1991
love the car
that sound sends shivers down my spine...
Never forget the 787 at winning at Le Mans - you could hear it all round the track at night. I went to support the jags but came back raving rotors - Love it
Sounds better than any F1 car in my books. the ultimate rotary powered Mazda
A truly unique & amazing sound...Never gets old...Seeing the 787B roar down the track is always inspirational...Love it...MAZDA FTW! :D
It used a 4-rotor R26B Wankel engine which produced over 700 hp (522 kW). Engine speed (RPMs) were deliberately kept low for longevity under the extreme stresses incurred during a 24-hour endurance race. The 787 was reported to have a redline around 9000rpm. However, interviews with Mazdas 787 race engineers revealed that the power of the quad-rotor increased dramatically above 9000rpm. One engineer stated that the car could develop more than 930hp with a redline around 10,500rpm.
THAT SOUND! OMG, this car is going on my bucket list!
The 7-Eighty Seven is possibly the coolest race machine ever...
I cried at the birth of my first child. She was so beautiful and innocent.
But I'd swap her in a heartbeat for just one lap at full throttle in that car.
He seems to be wearing some sort of flight helmet. I doubt it would offer as much protection in the event of an accident as a proper auto sports helmet would.
This car is freakin awesome!
@nipponbaka the 700hp"mode" is actually the lowered setup. the car actually produced over 900hp, but they brought it down to 700hp to extend the engine's life ...
To expand on that for those who don't know, the 787B's were handed a HUGE advantage prior to the 1991 Le Mans race. The Mazda's (for reasons I forget) were permitted to run a full 100kg lighter than most of their opposition. During the race it's self, the Mercedes C11's had a huge lead come Sunday morning, but failed one by one handing the lead to the super reliable (and very lucky) 787B's. Don't get me wrong, I salute their success but it was handed to them on a plate..
man what a car, WHAT A CAR. one of the best race cars ever.
Great machine!
The pilot gets out of the Mazda monster like I get out of my Fiat 500, just a regular day at the office...at 200MPH that is!!!!!
First time I saw this car was on GT3, but could never buy it... got it on GT4 with some hard work... I just love it in real!!!
Ah, this is a GLORIOUS video! Let's see here. The sound we're hearing is like that of a 2.6 liter two stroke 4-cylinder, which inflates to a 5.2 liter 4-stroke. I'll bet the torque curve is as flat as a board, so it pulls from idle to rev limiter, no matter what, if only it were equipped with short gear ratios.
This car is special because every revolution an engine cylinder intakes gas and air into the chamber, explodes the gas and ejects the carbon dioxide. Unlike standard engine that uses 2 revolutions to do that.
In 1991, Mazda became the first and only Japanese car manufacturer to win the prestigous 24 Hours of Le Mans endurance race. Using the Wankel rotary engine, it was also the only non-piston engine car to ever win. All three Mazda 787B cars to enter the race finished the gruelling event in respectable 1st, 6th and 8th positions. Of a total of 46 entrants, only 12 cars officially finished the race, 4 did not make the required classification, 22 did not finish.
Wow pal!!!!!!! This is no noise bud, more respect to the rotors!
It has a lovely exhaust note.
@carmodifire They're on totally different classes. RB26 is undisputed king of streets, but R26B is an amazing racing engine, it's somewhere high above in the place of it's own.
greatest car sound on planet and no1 car in Gran Tourismo parts...
i just got goosebumps only because of the sound! I love it!
is it just me or does that sound send shivers up your back?
Rotary-POWER!
The 787b was an amazing car!!!
CGTV is the best tv program in japan from over 25 years
unique engine, beautiful looks and sounds, and lemans winner.. this car was my favorite on ps2. as soon i found out AutoArt made a 1/18 scale, I knew I had to pick it up!
@Astidcrisse
well, sort of. it's a lot of valve overlap that causes it. and that makes more power at high revs by using the exaust pulsation to draw more air in the cilinder. so it's not designed in on purpose, it's a by-product of the valve overlap
I cant imagine any sexier thing in the world than this car screaming loud and spitting flames during shifting.
Here is the proof that rotaries are more powerful than any piston engine. No one could ever compete against this car because of it's light weight. This is why it was ban from the Le Man's 24 hour race. It's light weight kept a distance against those pistons! Rotary for life.
What....a....sound...soundtrack of the soul :)
His helmet looks like one of a spaceship pilot. In any other car that would have been ridiculous, but in this one it makes sense.
Such an awesome car, would love to see (and hear) it again in real life!
the car was banned because the engine was deemed too reliable, only having 5 moving parts gives it advantage against its piston counterparts in endurance races. After this car finished the lemans race, the engine was disassembled and inspected. The inspectors at the track fully admitted that the R26B would have kept running for at least another 24 hours.
Best engine sound of a race car ever :')
The sound of the Furai concept is also lovely :)
Btw, those special black racers will be every 694 days for sale.
it's not due to running rich per se, it's the design of the engine. there is no actual exaust stroke or valve. the port opens directly after the power "stroke". two strokes tend to have the exact same thing
That is one of the best soundings engines ever. Awesome!
Exactly
I would definitely prefer the vroom vroom from a gas burner than the dooga dooga of a diesel beater!
hahaha This is the car that i used to win almost all my races in grand turimo 3 and 4
90º which means 4 power events for every E-Shaft rotation, that is why they sound as if they rev a helowa lot higher than they actually are.
personally I like the 20B sound a bit more, They are spaced 120º so the tone is a tad bit lower....
the 13b's having only 2 rotors, are obviously spaced 180º. giving the rough sounding, but still awesome tone....
This car is amazing, the only japanese car that winning le mans, Mazda 787b, beautifull, powerfull, legend.
Would be cool to see Mazda's improvements in rotaries duking it out against the diesels in Lemans.
@deggis4 i belive the 787B does not meet regulations anymore because the 4-rotor engine was "an unfair advantage" or so it would seem.
the 787 was powered by the 4rotor engine, and made its debute in 1990 in the 24hr's of lemans. the next year they introduced the 787B and ( it won or nearly won i cant remember)
after that i cant find anything on it, i can only asume they change the regulations cuz the car wooped ass, hell it started in 19th and at the 19th hr it was in first !
@420rogerz it was banned for a few reason weight, power, reliablity and in '91 the 787b's finished 1st , 6th & 8th. The Mazda RX-7 has won more IMSA races in its class than any other model of automobile, with its one hundredth victory on September 2, 1990. Following that, the RX-7 won its class in the IMSA 24 Hours of Daytona race ten years in a row, starting in 1982. The RX7 won the IMSA Grand Touring Under Two Liter (GTU) championship each year from 1980 through 1987, in all rotorys are king
Unbelievable!Amazing sound and speed too!
I got a panic attack from this video....But it was the best panic attack I ever had!
Simply stunning!!! The sound is amazing!!!
787b was an untamed beast!
i owuld seriously be stoked to drive the 787B
the most advanced and fast car FOR ITS TIME. I think the audi R8 or even the audi R10 would cream it in another 24 hour race. the 787b is legendary in the end, however.
Wow!
Legendary sports racing car, falls in with the Jaguar XJR9LM & the Sauber Mercs. Though this car uses alot of fuel, it won Le Mans coz it was a bit more economical than the Jags & the Mercs!!!
Awesome engine noise, it's like a mix of a bike engine & a F1 car, but still can't beat the 917K's engine noise.
my God! that is a monster, even within the supercars that engine sound strikes fear.
nicest car in the world and with the nicest sound
Great car, nice sound.
I'd like seeing them running Le Mans today. If they were allowed to.
This was my favorite Le Mans car in the GT3 series. It just sounds amazing.
You mean in the Group C series
They're more like a 1 stroke or something (no idea), because on one rotor rotation the output shaft spins three times, and there are three combustions, so it's like one combustion per rotation of the output shaft.
I think, or something.
the problem was it ran in the 3 liter class but, its the equivilant of running to 250cc 2 stroke bike in a 250cc 4 stroke class. The engine makes more power for its size.
there's actually footage of a car based on this one in the new motorstorm game, although it's not in the copies that made it to retail so it may be dlc.
amazing real-life machine nonetheless.
yees but the Rev limit is set to the maximum fatiuge strength of the engine and its insternal components. most engines will rev till they blow all dependant on the losses through friction and werether it can reach a equilibrium with the combustion(highly unlikely though, head the 787b can hit up to 10,500rpm and pull a figure like 710hp(unofficial), they capped it at 9000 for reliability in lemans
@fergus1494 And as for the Porsche 962 has never been banned, it was the replacement for the 956 which was banned in the US series on safety grounds as the driver's feet were ahead of the front axle center line. Jochen Dauer got the 962 re-classified as a road legal GT1 car under a loophole in the new ACO regulations for the 1994 24 Hours of Le Mans.
i love the sound of this thing, BAD ASS
simply love that car
1991 LeMans winner
Mazda was forbiden to use the rotary engine 'cause it could run for 48h straight
or was forbiden cause it's damn good
26B 700hp N/A... crazy :P
Say what you will about the diesels, but I kinda dig being able to hear all the other sounds that the engine normally covers, i.e. the gearbox. I wouldn't want a whole grid of diesels, but a couple is cool. plus maybe the new engine in the R15 will sound better.
@oOranjeo I think that, from a tuner's point, the older engine would be better, but from a manufacturer's point, more technology to improve the rotary is better. Also, it gives the tuner's a better platform, once the price goes down. I found a way to somewhat solve the thermal expansion problem of the rotary engine, it should give more efficiency and power.
you gotta rep for the raw rotory power..it sounds like a mix between a 500hp muscle car and a crotch rocket/F1 indy car. and i love the colors!!!
That is a really... REALLY beautiful car!
one of the best cars EVER!!! along with audi r10 tdi....amazing sound
@randomspeedfreak No rubbish. If the rotary concept would be worth a penny all major manufacturers would use it!
engine sounds like one really loud, pissed off jack terrier....awesome!
this car is the reason why I want to swap out my 13b motor in my Mazda RX8 for a 20b motor.. yes, i know its not the same (4 rotary engines in the 787b).. but its as close as i can get to a high performance rotary :)
@Subsw00fers You have a point but it's still misleading to imply that only one type of engine was banned (what many people seem to think) because there never was a rule specially against rotaries. Every manufacturer faced the same sitaution because none of them used 3.5L NA engines in 1990. In 1991 the early adopters Jaguar and Mercedes started experimenting with ones. Mazda actually continued (sadly with only Peugeot and Toyota) to the 1992 season, using a rebadged Judd V10.
Now I am a proud male. I fight bears with my bare hands, I eat everything raw. I eat children for breakfast and chuck norris is my uncle. I even wear Old Spice. But listening to the 787b scream.... its the only time I cry.
@angryteddybear it wasnt banned. they just changed the rules.. alot of the grid also couldnt run the next year and they had been planning it long before the 787b wont its first race
You're forgetting the number of firing impulses per rev. With a 4-rotor engine, at the same RPM it will sound like a higher pitch than the RX8's 2-rotor engine because there are twice as many firing impulses for each rev.
@Subsw00fers (Continues) I think there's a difference between "being banned" and "not meeting the regulations". In racing context being banned kind of implies that something was first legal under the rulebook but then was made illegal by a specific rule change to the same rulebook, which is not the case with the 787B.
Incredible sound!
Probably my favourite Le Mans car ever.
Imagine if this came out to be in produciton, super car, would be soo good and damn expensive.
Gotta love that paint scheme!
@Amypr1ncess I understand where you come from, but the msp is flawed and theres no reason for the engine to rev out to 10 and just from a racing stand point people will swap in one of the 13b or 20b engines into their cars over the newer msp engines. But, I like the points you make and you actually understand the rotary engine unlike most people.
Impresinante. Ese coche es mi ídolo.
Gotchu!
The best Mazda 24 Le Mans
@CemetaryGatesML "Anymore" - we're talking about 20 year old events, so there there are no current regulations as the (World Sportscar) Championship ceased in 1992. Le Mans has continued and new series has been created but they're not related to the Group C regulations used between 1982-1992/93.
As I have already explained in my previously here, there was no "unfair advantage" and the regulations changes had absolutely nothing to do with Mazda. This is the point I'm trying to made.
es un buen video demuestra el poder del mazda 787b, ami parecer me gusta el video.
the best sound in the world
the sound is awesome
Correction, they produce very little low end torque, they produce a fair amount of torque at higher RPM.
man, what a sound. awesome is a down statement. Amazing car.
Oh it went down in history alright. It won le-mans and was promptly banned with many other manufacturers having a bitch about how much power the rotor made, despite its smaller capacity. It remains the only Rotary to win Le-Mans and i think (could be wrong) the first and possibly only Japanese car to win as well.
wonderful sound!
