The German automotive industry is renowned for its engineering excellence, particularly in the field of high-performance engines. Here’s a look back at five engines that have made their mark on the history of sports cars made in Germany and continue to influence the sector today.
The legendary 4-cylinder of the BMW M3 E30: the birth of an icon
The BMW M3 E30 revolutionized the sports sedan segment in the 1980s with its 2.3-liter 4-cylinder engine derived from Formula 2. Initially developing 200 hp at 6,750 rpm, this 16-valve naturally aspirated unit was a true concentration of technology for the time.
Paired with a 5-speed manual gearbox and a limited-slip differential, it propelled the M3 from 0 to 100 km/h in just 7 seconds, for a top speed of 235 km/h. Impressive figures that made this model an absolute benchmark in terms of performance and road handling.
Over the course of the evolutions, the displacement was increased to 2.5 liters to reach 238 hp on the Evo III version. This engine is today considered one of the best 4-cylinders ever produced, helping to make the M3 E30 a real collector's item whose price continues to rise.
The Mercedes OM615 engine: the embodiment of German reliability
While German sports cars shine with their performance, the German manufacturers' reputation for reliability has been built on more modest but indestructible engines. Mercedes' OM615 4-cylinder diesel is the perfect example.
Launched in the mid-70s on the legendary Mercedes W123, this 2.4-litre naturally aspirated engine developed 75 hp. Modest performance, but a robustness that made its reputation. Designed to last for several decades, it still equips many taxis in some countries today, proof of its exceptional longevity.
Its simple design and easy maintenance have made it a popular engine among professionals. Despite the evolution of anti-pollution standards, it remains a benchmark in terms of reliability and contributes to Mercedes' reputation for excellence in this field.
The Mercedes 190E 2.5-16 Evolution II's 4-cylinder Cosworth: the answer to the M3
In response to the success of the BMW M3, Mercedes responded with its own sports saloon: the 190E 2.5-16 Evolution II. Its 2.5-litre 4-cylinder engine, developed in collaboration with Cosworth, was a true technological gem.
Equipped with a specific cylinder head and an optimized injection system, this block delivered 235 hp at 7200 rpm. Its ability to climb in the revs made it a formidable competitor for the BMW engine, while retaining the reliability dear to Mercedes.
This engine allowed the star brand to shine in competition, particularly in DTM, while offering exceptional sensations on the road. It remains today considered one of the best 4-cylinders in history, combining performance and intoxicating sound.
The flat-4 turbo of the Porsche 718 Boxster and Cayman: the modern evolution
While the iconic engines mentioned above are a thing of the past, German manufacturers continue to innovate in the field of high-performance 4-cylinder engines. The 2.0-liter turbocharged flat-4 in the Porsche 718 is a perfect illustration of this.
Developing 300 hp and 380 Nm of torque (350 hp and 420 Nm on the S version), this rear-mounted mid-engine offers performance worthy of the best 6-cylinders. Capable of propelling the Boxster from 0 to 100 km/h in 4.7 seconds (4.2 s for the S version), it combines efficiency and sensations.
Although criticized by some purists for its less flattering sound than the naturally aspirated flat-6 it replaces, this engine demonstrates the ability of German engineers to adapt to new standards while preserving the driving pleasure dear to the brand.
The 4-cylinder plug-in hybrid of the Mercedes-AMG C 63 SE Performance: the future of German sports cars
Changing regulations are forcing manufacturers to rethink their engines. The Mercedes-AMG C 63 SE Performance is a perfect illustration of this trend with its 2.0-litre 4-cylinder plug-in hybrid.
Developed with technologies from Formula 1, this block is the most powerful 4-cylinder series engine in the world. Combined with an electric turbocharger, it delivers 476 hp and 545 Nm. Coupled with a 204 hp electric motor, the cumulative power reaches 680 hp and 1020 Nm of torque.
These stratospheric figures allow the saloon to go from 0 to 100 km/h in 3.4 seconds and reach a top speed of 280 km/h. A brilliant demonstration of the potential of modern 4-cylinder engines, capable of competing with the best V8s while reducing consumption and emissions.
In conclusion, the history of German 4-cylinder engines is rich in innovations that have shaped the automotive industry. From legendary naturally aspirated engines to high-performance plug-in hybrids, these engines demonstrate the ability of German manufacturers to push the boundaries of technology while preserving the values of performance and reliability that have made their reputation.
