The M2 is the only model in its segment to be offered with an inline 6-cylinder engine, which impresses not only with its balanced performance characteristics, but also its superior power. The engine is paired with either a 6-speed manual gearbox or a dynamic 8-speed M Steptronic transmission with Drivelogic. In either case, the engine’s power is fed through to the road in traditional fashion via the rear wheels.

With 453 hp at 6,250 rpm, the S58 engine in the new M2 outguns the unit in its predecessor by 48 hp. It combines the latest M TwinPower Turbo technology with the high-revving character drivers have come to expect of an M car. The engine’s peak torque of 406 lb-ft is produced between 2,650 and 5,870 rpm. Urgent response, an appetite for revs, and linear power delivery into the highest reaches of the engine speed range define the performance experience in the new BMW M2. The engine revs to a maximum 7,200 rpm.

The design principle behind the engine and its technical details reflect decades of experience amassed by BMW M GmbH in motorsport. An extremely rigid crankcase, friction-optimized cylinder bores, a crankshaft drive with high torsional rigidity, and a forged crankshaft with lightweight design enhance the efficiency, power development, and high-revving nature of the engine. The core of the cylinder head is 3D printed, enabling a weight reduction and optimized coolant duct routing.

Two mono-scroll turbochargers supply compressed air to the combustion chambers. The turbocharging system also features an indirect intercooler and an electronically controlled wastegate. Other elements of M TwinPower Turbo technology include High Precision Injection with maximum pressure of over 5,000 psi, VALVETRONIC variable valve timing and Double-VANOS fully variable camshaft timing.

The M-specific cooling system is fed fresh air through the large apertures in the front apron, and it ensures the powertrain components maintain optimal operating temperatures at all times – both in everyday use over short distances or in urban areas and during high-speed track sessions. The oil supply system is also designed to handle extreme dynamic driving situations. An oil sump with two separate chambers and an additional suction stage allows the map-controlled oil pump to keep lubricant flowing reliably even under high lateral and longitudinal acceleration loads.

The new BMW M2 comes standard with a six-speed manual gearbox, creating a performance experience in the classical mold, rooted in the heightened interaction between car and driver. The gear ratios and spread are perfectly matched to the performance characteristics of the engine. A precisely defined shift action enables rapid, easily executed gear changes, and the Gear Shift Assistant uses rev matching to ensure slip-free operation when downshifting. Gear Shift Assistant can be deactivated in the M Setup menu.

The available eight-speed M Steptronic transmission is also distinguished by ratio spacing perfectly attuned to the engine’s characteristics and also offers befittingly sporty gear shifts. The broadly spread gears aid efficiency at low engine speeds while enabling an intense rush of power from low road speeds.

The transmission’s shift characteristics can be varied using the Drivelogic button integrated into the selector lever, with a choice of three clearly distinguishable settings available in both automatic and manual mode. Besides a more comfort-oriented setup and a setting for sporty driving, drivers are also able to activate a track-optimized shift program.Choosing the manual or automatic gearbox will have only a minor effect on performance. The new M2 fitted with the 6-speed manual can accelerate from 0 to 60 mph in just 4.1 seconds, while the eight-speed M Steptronic transmission trims that time to 3.9 seconds. Top speed is electronically limited to 155 mph, or 177 mph if the optional M Driver’s Package is specified.

By sending power exclusively to the rear wheels, the new BMW M2 adheres to the traditional recipe for converting engine output into dynamic performance. When pushing hard on the track, the driver can use the linear build-up of cornering forces characteristic of M models to guide the car through corners with absolute precision.

Another contributor to the sublime dynamics of the BMW M2 is the standard Active M Differential. It can stop rotational speed compensation between the rear wheels whenever required and generate a locking effect of up to 100 percent seamlessly and variably. This optimizes traction on road surfaces offering different levels of adhesion at the left- and right- rear wheels. The differential lock ensures drive torque is not lost through slip at one or the other rear wheel but can instead be used to pull away more quickly. The Active M Differential is networked with the DSC (Dynamic Stability Control) system and adapts its locking effect precisely to the driving situation at hand, as detected by an array of sensors. Among the factors considered are drive torque, wheel speed, vehicle speed, and lateral acceleration, as well as the car’s steering angle and yaw rate. This allows the degree of lock to be adjusted very precisely and predictably for the driver. For example, when accelerating hard out of corners, drivers are given tangible feedback on the grip available at the rear wheels and can therefore apply just the right amount of throttle.

Sophisticated chassis technology originally developed for the M3 an M4 endows the new M2 with the tools required to convert the power of its straight-six engine into sublime straight-line and lateral performance, both in everyday driving and on the track. At the same time, the compact dimensions, short wheelbase, excellent longitudinal and torsional stiffness of the body and chassis mountings, and a nearly 50:50 weight distribution combine to deliver precisely controllable, fingertip handling. Add classical rear-wheel drive to the mix and the result is driving pleasure of incomparable purity.

The torsional stiffness of the front is further increased by unique links connecting the individual spring strut towers with one another and with the nose of the vehicle and the bulkhead. Vertical braces connect the stiffening elements of the engine compartment to the front axle subframe, whose supporting base has been enlarged by the addition of an attachment point at the base of the A-pillars. The M-specific aluminum front axle subframe is given extra rigidity by a single-piece aluminum shear panel with integral sill braces. The center and rear sections of the body incorporate model-specific C-pillar reinforcements and luggage compartment stiffening elements, together with a three-piece rear axle shear panel and a rear axle subframe with a rigid connection to the body.

The suspension on the new BMW M2 has M-specific kinematic and elastokinematic properties, which combine with the large castor and kingpin angles and the lowered roll center to produce both dynamic handling and carefully calibrated comfort-focused attributes. The M-specific version of the double-joint spring strut front axle comprises aluminum wishbones with ball joints, an aluminum torque arm with newly developed mounting, a forged swivel bearing with a unique spring strut clamp, and lightweight wheel bearings with very high camber stability. The five-link rear axle with M-specific upgrades provides the ideal basis for direct, high-precision response in highly dynamic driving situations with its wide track and rigid mounting.

The M Servotronic steering facilitates accurate turn-in when powering through bends on the one hand and effortless parking and maneuvering on the other. It does so by combining the benefits of speed-sensitive power assistance and a variable steering ratio. There is a choice of two settings for steering response in the M Setup menu. Comfort mode combines a light steering feel with precise feedback. And in the Sport setting the steering becomes much more communicative while also increasing steering effort – for maximum precision when exploring the outer reaches of the car’s dynamic abilities.

The standard Adaptive M Suspension features electronically controlled dampers designed to maximize road contact and traction in all driving situations. The dampers are controlled with the help of sensors that constantly monitor body movements, the condition of the road, and steering adjustments. Electromagnetically controlled valves generate fully variable damping forces for each individual wheel, as required and with split-second speed. The basic damper characteristics can be altered as desired by selecting one of the three settings in the M Setup menu.

The M Compound brakes on the new BMW M2 – six-piston, fixed-caliper brakes with 15-inch discs at the front, and single-piston, floating-caliper brakes with 14.6-inch discs at the rear – deliver outstanding stopping power. The calipers are painted in Blue metallic as standard, with a Red finish available as an option.

The integrated braking system erases speed with great precision. This system brings together the brake activation, brake booster, and braking control functions within a compact module. The required brake pressure is triggered quickly and precisely using an electric actuator. Here, the integrated braking system is fitted in an M-specific version that offers the driver two pedal feel settings, allowing them to choose between more comfort-oriented or very direct execution of brake pedal inputs in the M Setup menu.

New to the BMW M2 are M light-alloy wheels with a larger diameter at the rear axle than at the front. This results in more effective transmission of lateral control forces at the driven wheels, making it possible to extract even more from the M2’s dynamic handling potential. The new BMW M2 comes with 19-inch light-alloy wheels at the front and 20-inch wheels at the rear fitted with tires measuring 275/35 ZR19 and 285/30 ZR20 at the front and rear respectively.

The inclusion of the integrated braking system enables the DSC (Dynamic Stability Control) system to act with even greater precision. Its range of functions includes M Dynamic Mode, which allows extra wheel slip to enhance an already sporty driving experience. The wheel slip limitation function has been integrated into the engine management on the new BMW M2. This eliminates the long signal paths to the DSC control unit, meaning that the corrective inputs are applied up to ten times faster than in conventional systems and with exceptional precision. Because the near-actuator wheel slip limitation function manages any loss of traction, especially when accelerating hard or taking corners at speed, the DSC system has to intervene far less frequently to maintain composed and assured handling with selective applications of the brakes at individual wheels.

The M Traction Control system, part of the standard M Drive Professional, allows drivers to specify one of 10 stages of DSC intervention. During outings on the track, drivers can carefully reduce the extent of control system intervention in order to configure a setup for controlled drifts that is precisely tailored to both track surface conditions and their personal preferences.

When it comes to functionality, ergonomics, and comfort, the standard equipment features in the new BMW M2 follow the lead of its powertrain and chassis technology by placing the emphasis squarely on focused driving pleasure. The M2’s cockpit, with its driver-centric design, features M-specific displays, controls, and configurations, as well as the advanced BMW Curved Display. A focused selection of options is available for enhancing driving comfort or adding visual flourishes to both the exterior and interior, allowing owners to personalize their new BMW M2 in just the way they want.

The 2023 M2 features newly designed M Sport seats with more pronounced side bolsters. They are upholstered in Vernasca leather with perforated surfaces and can be ordered in either Black or Cognac. Their integral head restraints feature an illuminated M logo. The M Sport seats likewise come with electrical adjustment, including for the height of the head restraints.

Optional for the first time on the M2 are the track-ready M Carbon bucket seat – part of the optional Carbon Package. Fully electric and heated, they feature integral head restraints and illuminated M2 badges just above the backrest. The use of carbon fiber-reinforced plastic (CFRP) in the structural elements of the seat bottom and backrest together with the cut-outs in the side bolsters and below the head restraints saves about 24 pounds over the standard M Sport seats.

Customers wishing to inject more sporting style into the cabin of the new BMW M2 can opt for M interior trim in Aluminum Rhombicle anthracite in place of the standard Black high-gloss. If the optional Carbon Fiber trim is specified, the shift paddles (on automatic transmission-equipped vehicles) and trim on the M leather steering wheel will be finished in carbon fiber along with the trim on the dashboard and center console.

There are two roof variants for the new BMW M2: an electrically operated glass slide/tilt moonroof offering a glass surface now larger by nearly 20 percent compared with the outgoing model is standard equipment. A weight-reducing M Carbon roof panel is optional and deletes the moonroof.

Choosing the optional Shadowline Package adds the M Shadowline lights and finishes the tips of the tailpipes in black. Also available is the Carbon Package, which bundles the aforementioned M Carbon roof, M Carbon bucket seats in Black Full Merino leather with striking contour lines finished in the BMW M tricolors around the backrests and headrests of the front seats, and carbon fiber interior trim.
