Porsche's mezger engine legacy: a 500-horsepower return to racing roots

Porsche isn't just known for its iconic supercars; they've consistently demonstrated an unmatched ability to design competitive engines. The M97/74, recently reintroduced, is a potent example of that expertise.

A ghost from the past – and a future for the road

Rumors swirled for nearly a decade: Maserati desperately needed a manual supercar. But the real story centered on Porsche, and a surprising collaboration. Ferdinand Piech, one of the company’s founding fathers, partnered with his old friend, Hans Mezger – a name synonymous with Porsche’s engineering prowess – to develop a six-cylinder boxer engine intended for both street and track applications. The challenge? Cost control. Piech understood immediately that a simple, efficient design was paramount, foregoing excessive complexity.

The core of the design remained remarkably similar to Porsche’s existing architecture, largely retaining the original boxy shape. Modifications included the addition of water cooling, a critical step for sustained performance. Mezger’s influence is undeniable; he’s been integral to Porsche’s boxer engine development for decades, even currently collaborating with Singer and playing a key role in the early 911 Turbos. This new iteration, the M30 – famously powering the legendary BMW 3.0 CSL ‘Batmobile’ – offered a breathtaking 0-60 mph sprint in a blistering 7.3 seconds; the M97/74 aspires to similar levels of dynamism, though with a different approach.

The M97/74, produced between 2015 and 2016, delivered a formidable 500 horsepower at 8,250 rpm, though its true potential remained largely untapped. It served as a direct successor to the near-discontinued V10 found in the Carrera GT, offering a compelling alternative. But the M97/74 wasn't just a replacement; it represented a return to Porsche's racing heritage. The engine climbed to a dizzying 9,000 rpm, producing a staggering 620 CV and 700 Nm of torque. It’s a testament to Mezger’s enduring legacy and Porsche’s commitment to delivering visceral, high-performance driving experiences. This engine’s return is more than just a technical achievement; it’s a nod to the past and a signal of Porsche’s future.”n
