The BMW M2 and Toyota GR Supra share a bond deeper than mere rivalry—they are siblings born of a bygone era, reincarnated in a modern world where straight-six engines still command reverence. This isn’t just a comparison of two sports coupes; it’s a duel between two philosophies of driving pleasure, each rooted in a lineage of mechanical purity. The M2, with its M Division pedigree, whispers of track-day exploits and precision engineering, while the GR Supra, co-developed with BMW, hums with a more organic, almost rebellious spirit. Yet beneath their contrasting exteriors lies a shared heartbeat: the unmistakable growl of a naturally aspirated inline-six. It’s this sonic and mechanical kinship that makes their rivalry so fascinating—and why enthusiasts can’t help but obsess over which one deserves their affection.
The straight-six engine, a relic of automotive nobility, has long been the gold standard for enthusiasts. Its inherent balance, silky smoothness, and ability to rev like a symphony make it the stuff of legend. In an age where turbos and electrification dominate, the inline-six stands as a defiant reminder of what driving once was—and what it could be again. The BMW M2 and Toyota GR Supra, despite their differences, both cling to this tradition, offering a tactile experience that modern engines often lack. But why does this particular configuration hold such an enduring fascination? Perhaps it’s the way the six cylinders dance in perfect harmony, or the way their exhaust notes resonate through the cabin, turning every drive into an event. Or maybe it’s the sheer rarity of seeing a new car equipped with such an engine in 2024. Whatever the reason, the straight-six showdown between these two icons is more than a comparison—it’s a celebration of automotive soul.
The Lineage of Legends: How the Straight-Six Became a Sacred Cow
The straight-six engine is older than most living car enthusiasts. Its origins trace back to the early 20th century, when engineers sought the perfect balance between power and refinement. Unlike V-configurations, which often suffer from vibrations, the inline-six’s layout allows for natural harmonic balance, reducing the need for complex counterweights. This inherent smoothness made it a favorite among performance and luxury brands alike. BMW, in particular, has built its reputation on the straight-six, from the legendary M10 of the 1960s to the S54 and S55 engines that powered the E46 M3 and later M2 models. The inline-six isn’t just an engine—it’s a cultural touchstone, a symbol of an era when driving was as much about sensation as it was about speed.
The Toyota GR Supra’s straight-six, while not as storied as BMW’s, carries its own weight of significance. Developed in collaboration with BMW, the B58 engine under its hood is a masterclass in modern engineering, blending old-school torque with contemporary reliability. It’s a testament to the fact that the straight-six isn’t a relic—it’s an evolution. The Supra’s engine, shared with the BMW Z4, proves that the configuration can still thrive in the 21st century, offering a blend of performance and practicality that few rivals can match. The Supra’s engine bay, with its exposed plumbing and polished components, feels like a shrine to mechanical purity, a stark contrast to the increasingly sealed-off world of modern cars.

Power and Precision: Dissecting the Engines Under the Hood
At the heart of the BMW M2 Competition lies the S55 engine, a twin-turbocharged inline-six that punches well above its weight. With 503 horsepower and 479 lb-ft of torque, it’s a brute in a compact package, capable of launching the M2 from 0-60 mph in just 3.8 seconds. The S55’s forced induction means instant throttle response, a trait that makes it feel alive at every twist of the wrist. But it’s not just about raw numbers—the S55’s character is defined by its exhaust note, a guttural growl that intensifies as the revs climb, a symphony of controlled chaos. The M2’s engine bay is a study in precision, with every component serving a purpose, from the intercooler mounted high in the engine bay to the carbon fiber driveshaft that reduces rotational mass.
The Toyota GR Supra, on the other hand, relies on the naturally aspirated B58, a 3.0-liter inline-six that prioritizes linearity over outright power. With 382 horsepower and 368 lb-ft of torque, it’s no slouch, but its true appeal lies in its rev-happy nature. The B58’s redline sits at a lofty 7,200 rpm, a figure that harks back to the days when engines were judged by their ability to scream rather than their ability to push. The Supra’s engine bay is a lesson in minimalism, with the B58’s polished intake manifold and exposed headers adding a touch of artistry to the mechanical landscape. Where the M2’s engine feels like a finely tuned weapon, the Supra’s feels like a precision instrument, each note resonating with clarity and purpose.
The differences between the two engines extend beyond their induction methods. The S55’s twin-turbo setup delivers linear power delivery, making it easier to exploit on the road or track. The B58, while lacking forced induction, offers a more immediate connection between throttle input and acceleration, a trait that rewards skilled drivers. It’s a classic case of quantity versus quality—brute force versus finesse. Yet both engines share a common trait: they are drivers’ engines, designed to reward engagement rather than simply transport. In a world where so many cars feel like appliances, the M2 and Supra stand out as reminders of what driving used to be—and what it can still be.
Chassis and Character: How Each Car Feels Behind the Wheel
The BMW M2 Competition is a study in precision. Its chassis, derived from the larger M2 CS, is a masterclass in suspension tuning, with adaptive dampers and a rear axle steering system that make it feel like it’s on rails. The steering is direct and communicative, every input met with immediate feedback. The M2’s cabin is a cocoon of performance, with carbon fiber accents, Alcantara upholstery, and a digital cockpit that puts the driver in control. It’s a car that demands attention, rewarding those who are willing to push it to its limits. The M2 doesn’t just drive—it performs, every corner a chance to test its limits, every straight a sprint to see how quickly it can devour the tarmac.
The Toyota GR Supra, by contrast, is a more relaxed affair. Its chassis, while competent, lacks the razor-sharp focus of the M2. The steering is lighter, the suspension softer, and the overall demeanor more laid-back. It’s a car that invites you to cruise, to enjoy the journey rather than conquer it. The Supra’s cabin is a blend of modern and retro, with a retro-futuristic infotainment system and leather-appointed seats that prioritize comfort over outright sportiness. It’s a car that feels more like a grand tourer than a track weapon, a distinction that becomes clear when you push it to its limits. The Supra is at its best when you’re not trying to extract every ounce of performance—it’s a car that rewards patience, its inline-six singing a sweet melody as you glide through the countryside.
Yet for all their differences, both cars share a common trait: they are drivers’ cars in a world that increasingly prioritizes convenience. The M2’s chassis is a lesson in how to make a car feel alive, while the Supra’s is a reminder that driving doesn’t always have to be about speed. It’s about the journey, the sensation of the engine humming at 6,000 rpm as you crest a hill, the way the wind rushes past as you push the car to its limits. These are cars that demand engagement, that refuse to be treated as mere appliances. In an era where so many vehicles are designed to be autonomous, the M2 and Supra stand as defiant reminders of what driving used to be—and what it can still be.
The Great Divide: Performance, Practicality, and the Human Element
Performance is where the BMW M2 Competition truly shines. With 503 horsepower and a 0-60 mph time of 3.8 seconds, it’s a car that can embarrass supercars in the right conditions. Its twin-turbocharged engine delivers relentless power, while its chassis ensures that power is put to the ground with minimal drama. The M2 is at home on a racetrack, its adaptive dampers and rear axle steering making it a formidable opponent in the hands of an experienced driver. It’s a car that rewards skill, that feels alive in a way that few modern performance cars can match. The M2 isn’t just fast—it’s exhilarating, a car that makes you feel like you’re piloting something special every time you get behind the wheel.
The Toyota GR Supra, while no slouch in the performance department, takes a different approach. With 382 horsepower and a 0-60 mph time of 4.1 seconds, it’s slower than the M2, but it makes up for it in character. The Supra’s naturally aspirated engine is a joy to rev, its exhaust note a symphony of mechanical harmony. The Supra is a car that’s more about the journey than the destination, a vehicle that invites you to cruise, to enjoy the sensation of driving rather than simply arrive at your destination. It’s a car that feels more like a classic grand tourer than a modern performance machine, a distinction that becomes clear when you spend time behind the wheel.
Practicality is another area where the two cars diverge. The M2 is a compact coupe, but it’s still a practical car, with enough space for passengers and luggage to make it a viable daily driver. The Supra, while slightly larger, is still a two-door coupe, with limited rear space and a trunk that’s more of an afterthought than a feature. Neither car is particularly practical, but that’s part of their appeal. These are cars designed for driving, not for hauling groceries or ferrying kids to soccer practice. They are machines that exist to provide pleasure, to make every drive an event. In a world where so many cars are designed to be everything to everyone, the M2 and Supra stand out as reminders of a time when cars were built for enthusiasts, by enthusiasts.

Yet the M2 and Supra prove that the inline-six isn’t just a relic—it’s an evolution. It’s a configuration that can still deliver the performance and refinement that enthusiasts crave, a reminder that driving doesn’t have to be about raw numbers or lap times. It can be about sensation, about the way an engine sounds, about the way it feels when you push it to its limits.
There’s something deeply human about the straight-six. It’s an engine that rewards engagement, that demands attention from the driver. It’s an engine that sings, that growls, that reminds you that driving is about more than just getting from point A to point B. In a world where so many cars feel like appliances, the M2 and Supra stand out as defiant reminders of what driving used to be—and what it can still be. They are cars that make you feel alive, that remind you that the road is more than just a strip of asphalt—it’s a stage, and you’re the star.
So which one deserves your affection? The answer, of course, depends on what you value most. If you crave raw power, razor-sharp handling, and a car that feels like it was built for the racetrack, the BMW M2 Competition is the clear choice. But if you prefer a more relaxed demeanor, a naturally aspirated engine that sings at high revs, and a car that feels like a classic grand tourer, the Toyota GR Supra might just steal your heart. Either way, you win. Because in the end, the real victory is the shared experience of driving a car with a straight-six under the hood—a car that reminds you that driving is about more than just getting there. It’s about the journey.
