There are cars that are fast, beautiful, and fun, but then there are some that define categories and create their own class of performance. If you admire the thrill of analog driving, the 1988 BMW E30 M3 has carved its place in history.
The late 80s was the golden age for racing, and for manufacturers to enter the FIA‘s Group A class. Because of that, manufacturers had to homologate a certain number of race cars as production models for the street. The E30 M3 was built exclusively for racing, but the M3 had to be made legal on the streets and for sale to the general public. It was never intended to be a luxury sports car, but rather a weapon on the track that happened to have a leather interior and passed emissions testing.
Form Follows Function
A simple glimpse tells you this car was never made for Sunday drives. But those aggressive lines were not drawn on a sketchpad for aesthetics, they were sculpted in a wind tunnel. In order to make the M3 competitive on the world’s most challenging circuits, the E30’s boxy design was tweaked to create more downforce and optimize handling. The prominent box flares were created to accommodate the wide racing slicks at the front and rear. But those wide flares are only a small part of the aero improvements made to the E30.
To create more downforce at the rear of the car, the C-pillar and rear window angle were both changed, requiring a custom-fitted roof extension to clear the rear window. The height of the trunk lid was increased by almost 2 inches. In addition, a massive wing was added to the rear of the car to decrease lift at higher speeds. The windshield was welded to the chassis to add more rigidity to the body structure. Aside from the hood, roof, and inner door panels, almost every exterior panel on the E30 M3 was unique to the M3. It is a true marvel of engineering that was made with the sole purpose of racing.
Powertrain: The Iconic S14 Straight-4
When you open the front-hinged hood of the M3, prepare to be surprised. Instead of finding the familiar smooth inline-six that BMW is so well known for, you are greeted with this view:
BMW M3 E30 Front Engine Compartment
Instead of using a six-cylinder engine, BMW opted for a four-cylinder. The reason for this was to reduce the car’s overall weight, but more importantly, to create a more responsive powerplant. The shorter engine allowed for a lower center of gravity and placed the engine further back in the chassis, improving the front’s turn-in response. The engine was developed by Paul Rosche and uses many familiar components from the M10 four-cylinder engine that powered the 2002.
The engine block is made of iron and was taken from the M1 supercar’s six-cylinder engine, but shortened to fit the M3’s needs. The S14 also used individual throttle bodies for quicker throttle response, which is a trait that is shared by the SAE’s modern M3s. This four-cylinder mill is an absolute joy to drive, it practically begs you to get out on track and utilize every inch of its 6,750-rpm powerband. At idle, it emits a deep, throaty mechanical clatter, but at higher RPMs it begins to sing a wailing, touring-car song that modern, heavily-muffled engines simply cannot replicate.
Chassis: From the Factory, a Weapon for the Track
Power is meaningless without control, and the E30’s lightweight powerplant was married to an equally talented chassis. The M3’s suspension was reinforced with stiffer springs, thicker anti-roll bars, and control arm bushings that were offset to induce more caster for improved response on-track. The M3’s steering is direct, communicative, and has no driver-assist technologies to mute its feel.
Every bump, every imperfection on the road is communicated to the driver with no filters or smootheners in place. This allows the M3 to reward skilled drivers with a true connection to the road. But even with such a talented chassis, the M3 will not baby you on the road. With the closest gear ratios found in a 5-speed manual, and a “dog-leg” first gear in the European-spec M3 to put second and third gears together, the E30 M3 handles corners and curves like the track-day weapon it was built to be. It is up to you to utilize every ounce of the car’s capabilities.
Ultimate Driving Machine
If we are talking about the E30 M3 and its legacy, the real superstar here is the sheer number of accolades this car has accumulated since its inception. While BMW did have to produce 5,000 M3s just to meet the homologation requirements for racing, this car was never just about the road. The E30 M3 was a racing machine, but it happened to have a production version that could be purchased at any BMW dealer. It would go on to dominate the FIA’s Group A world touring car competition.
From battling with the mighty Mercedes-Benz 190E 2.3-16 Cosworth and the turbocharged Ford Sierra RS500, the E30 M3 would see some of the most competitive racing in motorsports history. Driven by legends like Roberto Ravaglia and Johnny Cecotto, this little M3 would go on to record an unbelievable 1,436 victories in just 1,000 days. From the Deutsche Tourenwagen Meisterschaft (DTM), British Touring Car Championship, the 24 Hours of Spa, the 24 Hours of Nürburgring, and more – the E30 M3 is regarded as the most successful touring car ever. When you climb behind the wheel of an E30 M3 from 1988, you will not just be driving a beautiful car. You are getting a front-row seat to the legacy of the ultimate driving machine.
The Iconic Pilots of the E30 M3
When DTM (Deutsche Tourenwagen Meisterschaft) racing series was on its peak, BMW E30 M3 secured its place as one of the most powerful touring cars with the help of strong and skillful drivers who raced it. First, the legendary Italian driver Roberto Ravaglia won the World Touring Car Championship in 1987 and came second in DTM in 1989. As he demonstrated his outstanding driving ability, BMW released a special “Ravaglia Edition” – a rare car that was based on his racing experience.
Another famous driver who raced the BMW M3 was a Venezeulan Johnny Cecotto. He was a two-time Grand Prix motorcycle road racer winner and could beat almost everyone on the race track. His unique driving style and aggressiveness allowed him to take the second position in the 1990 DTM. As a result, BMW released his special edition called “Cecotto Edition”.
When you turn on the ignition in the M3 from 1988, you are not only experiencing a sports car from a bygone era. It’s the purest, almost naked form of motorsport that could exist, a direct descendant of the fastest cars on the track, but in the shape of an accessible roadster that offers the driver the chance to experience unadulterated driving performance. This was the BMW 1988 E30 M3.
