No matter the trim, all 2025 BMW M3s come equipped with the brand’s twin-turbo 3.0-liter inline six-cylinder engine, known to brand aficionados as the S58. However, power levels vary. In base spec, the M3 produces 473 horsepower and 406 pound-feet of torque, whereas jumping up to the Competition trim increases those figures to 503 hp and 479 lb-ft. These are all massive numbers made possible by being turbocharged, plus BMW’s Vanos variable valve timing, Valvetronic throttle body-less intake technology, and a big air-to-water intercooler bolted up just before the intake charge reaches the valvetrain.
RWD is standard, and opting for BMW’s xDrive AWD system is possible in only Competition spec—in fact, it’s its own trim: The BMW M3 Competition xDrive.
A six-speed manual transmission is the sole option for the base model, whereas Competition trims get a ZF eight-speed automatic transmission. Between all three, curb weight is right around 3,900 pounds. This may seem a bit portly, but their reported 0-60 mph times tell a different story: The base hits the mark in a reported 4.1 seconds, whereas the Competition and Competition xDrive do so in 3.8 and 3.4, respectively. Our tester, the Competition xDrive, certainly felt like it, too.
With a little courage and a heavy right foot, our AWD tester ripped off the line with reckless abandon and let out an angry howl all the way to redline. No matter the speed, we always had more than enough power on-tap, including enough to get into deep trouble while making otherwise casual passes on the highway. This powertrain means serious business. Between the 2025 M3’s power, weight, nicely insulated interior, and size, extra-legal speeds felt far lower than they actually were—talk about paying homage to German super sedans of yore, like its F80-generation predecessor, the E39 and E60 BMW M5, and so on.
When the road got twisty, particularly in the mountains above Los Angeles, the 2025 BMW M3’s driving experience was non-stop fun. Whether ripping out of corners or heavily braking on our way into them, it always felt amply athletic and capable, offering up all the confidence. We never had any fear of overheating, as part of the reason for the M3’s iconic face is due to all of the cooling going on behind it: Oil coolers, heat exchangers, a transmission cooler, and more.
Whether configured with RWD or AWD, grip was impressive while sailing through all kinds of fun corners, with nonexistent body roll when the adaptive dampers were configured to Sport, and a bit too track focused (as in, stiff) when in Sport Plus. Which brings up one of our top favorite features: Customization. We enjoyed the flexibility of diving into iDrive’s M settings and adjusting not only damper stiffness, but also throttle tuning, steering action, exhaust volume—either quiet or slightly less quiet—brake pedal sensitivity, and traction control.
Then, two M buttons atop the steering wheel’s left and right spokes allowed us to quickly toggle our favorite mix of settings. For general around-town and highway driving, we set most everything to mid-level sporty utilizing the M1 button. Compression and rebound damping were plenty comfortable for all forms of city driving, yet never hid the M3's sports-car character.
On the other hand, the M2 button was reserved for everything cranked up to ferocious and track-ready levels for optimum poise, grip, and thrills, including barely-there traction control.
With the drivetrain in RWD—that’s right, you can turn off the front wheels for classic BMW hijinks—we had a little too much fun playing with the latter. BMW’s M traction control has 10 levels of intensity, with our favorite being one notch away from fully off. If we had the sudden urge to enjoy some brief, harmless oversteer (but not risk spinning out in a haze of broken wheels and busted egos) this system was there to keep an eye on things. It made for some laughter-filled moments.
When it came to steering, handling, and braking, the M3’s fast steering ratio and very direct input made for precise front-end control, though its weight was too light for our liking at speed. Overall, this big German sedan was incredibly grippy and capable, but we could still feel its heft get slung around during rapid lateral G changes—it’s awfully tough to hide nearly two tons of steel, aluminum, and carbon fiber. Its biggest-M3-ever footprint doesn’t help it here, either. Still, the massive carbon ceramic 15.7-inch front and 15-inch rear brakes were always up to task, and the pedal had great feel and modulation in either Comfort or Sport mode.
