It’s abating to apperceive that not alike a all-around communicable can stop the adamant advance advanced of BMW’s following of power, torque, and active fun. Proving our point is today’s basal rollout of the 2021 BMW M4, antic the amazing new S58 agent attainable in two states of tune and with a best of chiral or automated transmissions. There’s alike a new M Drive Professional apartment of onboard achievement analyzers, including M Alluvion Analyzer and M Laptimer, and anon it will alike action M xDrive achievement all-wheel drive. Hey, active your own car fast about a clue is de facto amusing distancing, right?
We aboriginal sampled the new, boss S58 agent in the BMW X3 M and X4 M SUVs and in the Competition models of each. Beneath the hoods of the 2021 BMW M3 and M4 it will accomplish the above application as in those SUVs—473 horses and in the approved model, 503 in the Competition—but torque is not equivalent. The SUVs get 442 lb-ft beyond the board, admitting the abject M4 gets 406 lb-ft and the Competition archetypal makes 479. For reference, the new abject M4 beats its absolute antecedent by 48 application and the aftermost M4 Competition by 29 horses; the new M4 Competition leapfrogs alike the boss M4 GTS by 10 horsepower. BMW claims a zero-to-60-mph time of 4.1 abnormal for the basal M4 and 3.8 for the Competition.
To recap, the 3.0-liter inline-six twin-turbo S58 agent is based on BMW’s modular B58 engine, and like the S55 that powered the antecedent bearing of M beasts, it appearance two mono-scroll turbochargers, wire-arc-sprayed low-friction butt liners, and a artificial crankshaft. Perhaps the S58’s coolest new affection is a lighter, cooling-optimized butt arch featuring a 3D-printed casting amount that’s awfully added absolute than a archetypal beach core, and which facilitates bigger cooling.
Opt for the abject M4 and you get a slick, close-ratio six-speed chiral chiral with a short-throw shifter and a Gear Shift Assistant rev-matching affection advised to advance directional adherence during advancing active by preventing adventitious rear-wheel deceleration (it can additionally be switched off). Opting for the Competition amalgamation signifies you’re austere about acceleration and can’t decay time arresting the torque during shifts, so you get a paddle-shifted ZF-supplied eight-speed M Steptronic automatic. It weighs 50 pounds added than the chiral and accouterment a bit of weight forward, but teamed with the stronger S58 agent tune, this is actually the quicker, faster setup. Starting in summer 2021, Competition models will be attainable with M xDrive as aboriginal sampled on the BMW M5, which consistently biases torque to the rear axle. A Action approach sends alike beneath torque forward, and a rear-wheel-drive approach is included but requires adherence ascendancy be switched off.
As before, the M3/M4 get all-encompassing animating to ensure able rigidity, bridging the shock building to the firewall and the advanced of the vehicle, and angular abutting the advanced abeyance carrier with the agent compartment, with still added braces beneath the axial and rear of the car. New ball-jointed lower links advice widen the advanced clue by 1.5 inches over the approachable archetypal for added crabbed absorption and directional stability. New M Integrated brakes affection 15.0-inch front/14.6-inch rear discs chomped by six-piston advanced and single-piston rear calipers with a anew developed brake-pad compound. A carbon-ceramic anchor arrangement charcoal alternative and is identifiable by gold calipers and beyond 15.7-inch advanced discs (metallic dejected calipers are standard, while red and atramentous are options with the approved brakes). There are two levels of anchor feel that can be programmed, as well. Speaking of settings, the new M Drive Professional amalgamation promises 10 (!) altered levels of wheel-slip limitation. Yes, the new M4 offers alike added adjustments than anytime before, as if anyone was allurement for that.
The new M Drive Professional and M Driver’s bales are not to be confused. The M Drivers’s Amalgamation bumps the acceleration limiter from 155 to 180 mph and includes a agenda to appear a BMW disciplinarian training school. (On the 2020 model, this advantage amount $2,500.) M Drive Professional is a new amalgamation of appearance to advice enthusiasts bigger adore the abounding abeyant of their M4, including the above 10-mode M Absorption Ascendancy function. It additionally adds a Clue approach to the accepted Road and Action M modes, attainable via a continued columnist and authority of the M button, which absolutely deactivates all abundance and assurance appearance and converts all displays to appearance alone track-focused information. An M Alluvion Analyzer annal the duration, ambit covered, line, and bend of a alluvion with a appraisement apparent on the Ascendancy Display. The M Laptimer affection advance key achievement metrics of a clue session, agreement them in the apparatus array and on the alternative head-up display. This allows drivers to see how abundant quicker or slower they are activity about to their fastest lap of the accepted session. The affairs advance cardinal of laps completed, ambit covered, and the continuance of the driver’s stint.

BMW claims the new M4 enjoys greater adverse from its 4 Series ancestors than anytime before, with its fenders badly flared to burrow the added tires and clue and affiliated by advanced and potentially shin-knocking rocker panels. The advanced end is assiduously redesigned, and the atramentous acclimated for the grille inserts is a huge (and slimming) beheld improvement, although that’s not difficult to achieve. (Smaller grilles, as apparent in this illustration, absolutely would be better.) Abounding LED headlights with fiber-optic daytime active lights are standard, with adaptive Laserlight lamps attainable as an option. In aback you’ll acquisition the archetypal diffuser, 4.0-inch bankrupt tips, and a lip spoiler. A carbon-fiber roof featuring longitudinal fins to administer airflow is standard, while an alternative M Carbon exoteric amalgamation adds carbon-fiber on the advanced air intakes, rear diffuser, exoteric mirror caps, and rear spoiler.
In the cabin, the coolest new alternative affection are the electric M Carbon brazier seats, which acclimatize lower than the accepted M action seats and counterbalance 21 pounds beneath while accouterment cutouts for a multi-point harness. They allegedly amalgamate race-ready bolstering with long-distance abundance and affection an aflame archetypal badge. Naturally there are red accents and accepted Aluminum Tetragon trim, the closing of which can of advance be replaced by carbon fiber. The 12.3-inch reconfigurable apparatus array and centermost displays get M specific screens to affectation all that air-conditioned M Drive Professional stuff.
The basal M4 auto starts at $72,795—$2,650 added than the 2020 model—while the Competition archetypal starts at $75,795, aloof $900 added than in 2020. (That’s $28,300 beneath than the CS, too.) They both go on auction in Advance of 2021, with M xDrive acceptable attainable on the Competition models after that summer. A convertible is accepted to accompany the calendar in the fall, as a 2022 model. An M4 Gran Auto is apparently not in the cards, which is unfortunate, but those with a charge for added doors charge alone attending to the appropriately new 2021 M3 sedan.
