The design of the BMW M3, unlike the standard model, has changed significantly. Changes were made to the side of the car, the arches were widened to widen the track, a spoiler was added to the front bumper, the rear bumper and side skirts were changed (which improved the buoyancy force and achieved better directional stability), the trunk lid was aerodynamically improved, and the rear window was aerodynamically reasons became flat. In addition, the windshield of the M3 coupe was glued, thanks to which the aerodynamic value was - 0.33 Cx.
Technically, the M3 coupe had special front and rear brake calipers and rotors, as well as a special brake master cylinder design.
The gearbox for the sports version was installed 5-speed manual.
The interior of the coupe included an on-board computer, air conditioning, radio, heated front seats (the control of which was installed on the center console between the handbrake and gear levers) and leather upholstery.
Power windows, power sunroof, headlight washer were installed as an option.
Since 1988, the option of Electronic Damper Control (EDC) has been added.
The EDC controller was located on the right side of the center console, and included three modes:
- K - Comfort
- N - Normal
- S-Sport
Engines
The first M3 model became available from March 1986, it was a 200-horsepower version of the European specification without a catalyst, and in May of the same year a 197-horsepower model equipped with an S14B23 engine with a catalyst joined the M3 lineup (the same power unit was installed in 1988 of the year).
In February 1987, a European 200-horsepower modification was released with a catalyst and a power of 192 hp. (motor S14B20).
In 1988, the first M3 was added to the lineup with a 220-horsepower engine without a catalyst.
Since April 1989, a 217-horsepower version with an M3 catalytic converter of European specification is available, as well as equipped with an S14B23 EVO2 engine.
Since December, a 235-horsepower catalytic converter has been available (S14B23 EVO3 engine).
Between 1987 and 1989, the . This modification of the M3 caused the contestation of several national championships and individual world rally championships. The M3 Prodrive was equipped with a six-speed manual transmission and a 295 hp engine. The most notable success was winning the Tour de Corse in 1987 with Bernard Begin.

Based on the M3 Coupe, two versions of the "Art Car" were created -
What do you think of the BMW M3 E30? That this is an old, "cushioned" and probably not too expensive car? In that case, I dare to suggest that you are quite far from the world of cars. First M3 is the DTM champion and the fastest four-seater convertible of its day. It's an outstanding car and you'll soon see why.
They say that Eberheim Künheim (Chairman of the Board of Directors of BMW), turning to Paul Roche (Technical Director of BMW) for help in creating a sports engine for a new three-ruble note in the bodyand had no idea that their new sports car would be so successful. It was originally planned to produce only 5,000 cars. That is how much was needed for the homologation and admission of their sports car to the Group A rally tracks. The required number was produced in only one year - 1987, and in total, from 1986 to 1991, almost 18,000 Emok were produced, including even more extreme modifications -evolutionandSport evolution. 
Paul Roche started his job at BMW when he was 23 years old. It was he who created the mighty turbo engine for Nelson Piquet's formula car, and this undoubtedly helped the latter become a champion in 1983. Roche became famous for the subtle, very accurate calculation of the camshafts, for which he received the nickname: - Paul-Kulachek.
as a basis, 
Roche took a six-cylinder central engine ,
gutted it and inserted the insides into a four-cylinder engine blockM10.Roche believed,
that since it makes a very high-speed engine, it is better to make it four, and not six-cylinder, because the long crankshaft of the in-line "six" at super high speeds is more prone to creating vibrations than the short crankshaft of the four. Later, the motor was namedS14B23became pridebmw, because he could withstand over 10,000 revolutions per minute without any problems.
By the way, the number 14 appeared in the name of this engine is not at all accidental. 
The fact is that thanks to the excellent skill of Paul Roche, as well as the existing developments, it took only 14 days to build a new motor, and the digital index follows from this. The numbers following the beech"B",as always in the case of BMW, indicate the size of the engine.
The price of the new BMW M3 E30 was 60,000 marks. This is despite the fact that the most expensive three-ruble note in the back of a convertible cost 45,000. Even more than the original cost, the price of this car is amazing today.
BMW M3 E30 –that's great rarity. The price of a car in a well-maintained condition can be over 50,000$. Today we can say unequivocally - Emka in the backE30among fans is valued much more than a more recent .
- About appearance:
Appearance M3speaks for itself. Look at those "inflated" fenders and wing. Is it possible to see this on a regular troika? looking at the photobmw m3 e30,note the "lip" under the bumper. This element also plays a very significant role in aerodynamics.M3.The drag coefficient of the sports trio is only 0.33. Already from the factory, Emka was equipped with fifteen discsbbs,front through which it was possible to see brake discs with a diameter of 280mm. Curb weight of Emka in the backE30 equals 1200kg.
- In the cabin:
If you are ever lucky enough to be in the cabin of the BMW M3 
in the thirtieth body, pay attention - in what order the driver changes gears. The first gear is turned on here - “toward itself”, - as the second is usually turned on. The second takes the place of the third, and the third, respectively, instead of the fourth. This is done in order to make it more convenient to switch between second and third, because it is in these gears that most of the shifts are made during racing races, the first speed is switched on only once - at the beginning of the race.
It is also interesting that glass modificationSport Evolutionwere thinner than base glassM3.This is one of the measures to reduce the weight of the car.
- SpecificationsBMW M3 E30
Yes, BMW M3 E engine30 confidently withstood 10,000 revolutions,
but on ordinary - civilian engines there was a cut-off at 6,750 rpm. The atmospheric "four" was equipped with a four-throttle intake and produced 195hp. This despite the fact that catalysts were built into the exhaust system, which, although they reduced the level of harmful emissions, had a negative effect on power. However, this is a 2.3-liter "four" pushes Emka forward with such force that it accelerates 100 km per hour in just 6.7 seconds, and the maximum speed of such a car is 235 km per hour. 
Agree, even by the standards of modern sports cars - these are very good characteristics.
Version evolutionreceived a modified exhaust and an increased compression ratio, which together made it possible to increase power to 215hp. The torque of such a machine is 250N.M.
Engine of the most extreme versionSport Evolutionwas increased in volume to 2.5l. Power then increased to 238l.s. Such a car is gaining a hundred in 6.4 seconds, and on the highway it can accelerate to 248 km per hour.
Interestingly, during the tests, the Emka's exhaust system heated up so much that in some places it expanded in diameter by as much as several centimeters, which led to damage to either the exhaust system itself or its fasteners. After the work done on the elimination of this nuance, Emki dashed off 150,000 km during tests on the Italian trackNardo,no further issues were noted with the release.
Already in those years, Emka was equipped with adjustable shock absorbers with three settings:Sport, Normal, Comfort.

Presentations of new "emok" worth attending at least for the sake of communication with their creators. This time it's Albert Biermann, Vice President of BMW M and head of all M developers. Briefly intercepting the air, he excitedly talks about the extraordinary machine. Engineers are passionate people, but usually restrained in their assessments, and Biermann did not skimp.
- We have the best electric power steering in the world: ZF completes components for "emok" parts with the smallest tolerances ...
He is like Santa Claus at a children's party, only without a beard and in polo with M-symbols. Whatever the word is a gift. We listen with open mouths and are amazed at the amount of work that has gone into the new M3/M4 family.
Albert Biermann came to the M department three times in his 31-year career at BMW. The first time was in 1985 to work on the Group A BMW M3 E30. M5 E39 and M3 E46. Then he switched back to sports and built the M3 GTR, the 320i for the ETCC and WTCC series, and a BMW Formula car. And after the successful completion of the second-generation X5 project, which Biermann also led, he was made the chief designer of the entire BMW M division. It does not take long to figure out to whom the X5M and X6M owe their existence ...
BMW M3 is the high-tech sports version of the BMW 3 Series compact cars from BMW M GmbH.
The M3 models are based on the E30, E36, E46, E90/E92/E93 and F80 3 Series.
Key differences from the "standard" 3 Series include a more powerful engine, improved suspension, more aggressive and aerodynamic bodywork, and multiple "M"/Motorsport line-up accents both in the interior and exterior.
E30
Based on the 1986 BMW 3 Series E30, the first model introduced had a 2.3 L inline-four S14B23 engine.
The engine design was based on previous BMW developments. Performed in many touring racing series, with considerable success.
The first version for public roads had 195 hp. with. (143 kW). The Evolution models had 2.3L engines, but a modified exhaust system, increased compression, and minor tweaks increased the output to 215 hp. with. (160 kW).
Later, the Sport Evolution model received 2.5 liter engines, which increased power to 238 hp. with. (175 kW).
786 convertibles were also produced, with a capacity of 215 hp. with. (160 kW) - it was the world's fastest four-seater convertible.
Differences from the standard BMW 3 Series
The M3 was equipped with an improved, reinforced and more aerodynamic body.
The BMW M3 was distinguished by swollen wings, a spoiler and a front lip - no analogues were made for standard models.
Also, the BMW M3 E30 featured a more gentle tilt of the rear windshield to improve the aerodynamic properties of the body.
Also, the front windshield was glued in to increase the rigidity of the body. The glazing was thinner.
In addition, the car received a stiffer and lower suspension with Bilstein B6 struts. The M3 is longer and wider than the standard BMW E30.
Also on the M3 were branded BBS wheels, on which wide low-profile tires were pulled.
1991 BMW M3 E30
2.3 l / 215 hp
Mileage - 90,000 km
The legendary car M3 E30, the record holder for the number of awards in motorsport. A real masterpiece of the automotive industry, the British characterize in one word - a diamond! In great condition. The mileage in Russia is no more than 10 thousand km. In the mid-90s, it was purchased in Germany, expensive, because it was in perfect condition even by the standards of Germany, it was immediately imported into Russia, cleared by customs, and stood in the garage. All customs and repair history is available. Served exclusively in Motorhome. Immediately upon arrival, all pipes, rubber bands, radiator, pump, suspension, etc. were replaced by new, equally original ones. In mind hypertrophied perfectionism. And, of course, Bilstein's favorite shock absorbers. Steering wheel replaced by MOMO, native did not like. The original color - black, was repainted during the WRC hobby, in vain, of course, but that's it. Analogues (in terms of condition, equipment, mileage) in Germany cost from 80 thousand euros. Over 300 thousand euros are given for a new car of the EVO series.

As promised today I present to your attention the BMW M3 e30 V10!!
I want to introduce you to my M3 E30. The story begins with how in the fall of 2008 I was with my friend and noticed a dusty E30 m3 body in the corner of the garage. As it turned out, since 1998, this m3 has been stationary due to a knocking engine. After a 2-week discussion with my girlfriend, I still took the body and began to completely rebuild it.
It did not take much time to disassemble, since the previous owner did almost all the work. For 10 years of idle time, the car had practically no rust, and only in some places I found small corrosion zones.
Each bolt; each clamp was brand new. In the beginning I rebuilt my S38 turbo engine. But after the first test run, I still changed my mind ... too much turbo lag, no.. it should not be! 10 minutes drive made me realize that this is unfortunately not a suitable base for getting high. It became clear that I want to return to strong atmotoram again. 5 years of turbo driving was enough.
In the end, I settled on the S85 motor from the M5 E60. The data speaks for itself, 507 hp with a cutoff of 8250 rpm and this infernal sound, it's hard to describe in words!
The goal was to build an m3 v10 with servo steering, BKV (honestly, I don’t know what it is) and what is important, original and comfortable motor control. This machine differs from 2 other m3 e30 v10 cruising in the network. (1 Swedish which Gustav had at the races, I don’t know the second one).
The car is equipped with KW suspension with custom springs and H / R sports stabilizers.
Brakes: Front 345mm discs from M3 e46 csl 6-piston from Porsche. Behind 325mm csl discs with 4-piston mechanism from Porsche.
I won’t bother you with text anymore .. we look and get high!
