Thirty-five years since the original BMW M3 was unveiled to the world, Munich has now removed the wrappers from the new BMW M3 G80 and BMW M4 G82. The latest high-performance sedan and coupe sticks to the usual formula for added power and chassis upgrades, but this time, they’ve deviated a bit from the script.
Yes, as you’ve probably seen from all the shots, leaks, and trailers, the new M3 and M4 will get a massive (and still divisive) new full-height grille, just like the new Series 4. Love it or hate it, it’ll be. the only thing everyone will be talking about, but a flex of your right foot will be all it takes to put them in the dust.
This is because the cars will come with a new S58 3.0-liter biturbo inline six, derived from the X3 and X4 M. It may be the same size as the old S55 mill, but a new 3D printed cylinder head core reduces the weight. optimizing the route of the cooling ducts.
The direct injection system has also been improved and now operates at a maximum pressure of 350 bar, while a particulate filter allows it to meet the latest Euro 6d emission standards. As before, the engine features a closed deck construction with a wire arc sprayed iron cylinder wall liner, forged crankshafts, Valvetronic variable valve timing, Double Vanos variable camshaft timing, and an improved cooling system.
Overall, the new engine produces 480 hp at 6,250 rpm and 550 Nm of torque from 2,650 to 6,130 rpm, which in itself is almost 50 hp and 50 Nm more than the outgoing F80 and F82 models. Better yet, all this power is routed as standard through an honest six-speed manual gearbox, which has a new hood to harness the extra power. Zero to 100 km / h ships in 4.2 seconds.
But that’s not all, because the M3 and M4 will also be offered at launch with competition specs. This reaches 510 hp at 6,250 rpm and 650 Nm between 2,750 and 5,500 rpm, increases close to 60 hp and 100 Nm with respect to previous Competition models. Only the eight-speed automatic transmission of the M5 and M8 models is available here, and so equipped, it destroys the sprint of the century in just 3.9 seconds.
The gearbox isn’t the only thing taken out of the bigger models: starting next summer, the M3 and M4 Competition will also be available with an optional M xDrive all-wheel drive system for the first time. An electronic multi-plate clutch distributes power variably to the front and rear wheels, while the active M differential distributes torque side-to-side to each rear wheel.
As with their bigger siblings, the xDrive models deliver torque only to the rear wheels under normal driving conditions, directing power to the front if a loss of traction is detected. The system features 4WD and 4WD Sport configurations, with the latter offering a greater rear camber. Alternatively, you can switch to 2WD mode with stability control off, allowing you to engage in side action.
To handle all that performance, the chassis features numerous custom suspension and structural upgrades. The unique aluminum front subframe has been equipped with strut tower tie rods, vertical bracing and a one-piece trim panel with integrated side tie rods. The center and rear sections have also been modified with a crossbar, additional reinforcement measures at the rear and a new rigidly mounted rear subframe.
Both the M3 and M4 benefit from a lower center of gravity, a wider front track and a standard-fit adaptive M suspension. The front double-link MacPherson struts come with aluminum torsion arms and torsion arms, a forged swivel bearing, lightweight wheel bearings, and custom kinematics with large pivot and pivot angles. The five-link rear axle gets model-specific forks and struts.
Overall, BMW claims to have a high level of stability and precision, a neutral steering behavior at the limit, and a linear build-up of lateral forces. All models come with speed-sensitive variable-ratio M Servotronic steering that reduces torque on all-wheel drive models, plus a cable-brake system with two pedal feel settings.
The latter, which is said to offer better generation of brake pressure and faster and more precise stability control intervention, is linked to the new M compound brakes with six-piston front calipers and 380mm front discs. These come with blue clamps as standard and are optionally available with a black or red finish. Carbon ceramic brakes are available as an option with 400mm front discs and gold calipers.
As usual, the M3 and M4 also get a more forgiving M dynamic mode for stability control, while the traction control system is now integrated into the ECU and responds up to ten times faster. The optional M Drive Professional system adds a new M Traction Control function that provides ten different levels of intervention, along with a lap timer and “drift analyzer.” It comes standard on Competition models.
That’s a huge list of updates, so for this generation, BMW has increased the visual aggression even further for a more outgoing appearance. That controversial grille protrudes from the front fascia and features new horizontal bars with the model’s emblem. It is flanked by 4 Series trapezoidal headlights and large air intakes that feed both the brakes and radiators. The aero flics are integrated into the vertical Air Curtain inlets.
Lines emanating from the grille flow to the hood which, oddly enough, features divots that only suggest there are vents. The front and rear fenders have been significantly stretched to wrap around the stepped wheels; For the first time, the rollers have a different diameter for the front and rear.
As standard, the M3 and M4 come with 18-inch front and 19-inch rear wheels wrapped in 275/40 and 285/35 section tires respectively, while all-wheel drive models get 19-inch and 20-inch front wheels. Inch rear wheels that are optional on the other models. They are shod with 275/35 section rubber on the front and 285/30 section rubber on the back.
Elsewhere, it has diagonal gills on the front fender, wider side skirts, dual-arm side mirrors, a small spoiler on the trunk lid, and a robust rear diffuser. The custom exhaust features four huge round exhaust tips that are chrome on standard cars and black on Competition models. The front splitters, side skirts and rear diffuser are finished in high-gloss black. New paint finishes include Sao Paulo Yellow, Isle of Man Green and Toronto Red.
The interior has been adorned with M sport seats, red M buttons on the steering wheel, a red start button and an illuminated gear stick on automatic models. Buyers can specify new (and very aggressive-looking) M carbon bucket seats with integrated headrests and illuminated model badges, while the optional carbon fiber accent trim also adds some slim carbon shift paddles with red trim.
