BMW has increased the power by 48 hp over the previous M3 and M4, and by 59 hp in the new Competition models. The new S58 engine generates 473 hp at 6,250 rpm and 406 lb-ft of torque between 2,650 and 6,130 rpm. The M3 Sedan and M4 Coupe can accelerate from 0-100 km/h in 4.2 seconds with a top speed of 250 km/h or 290 km/h when the M Driver’s Package is selected. The Competition models produce 503 hp at 6,250 rpm and 479 lb-ft of torque between 2,750 and 5,500 rpm reducing 0-100 km/h sprints to just 3.9 seconds, with similar top speeds. Redline is 7,200 rpm.
The standard M Compound brakes have been newly developed for the 2021 BMW M3 and M4 and feature front six-piston fixed-caliper brakes with 380 mm discs and rear single-piston floating-calipers with 370 mm disks. The calipers are painted in blue metallic but may be ordered in black or red; all with the M logo. The optional M Carbon ceramic brakes deliver even stronger braking power with greater fade resistance, enhanced thermal stability and extremely high resistance to wear. Their gold painted calipers are complemented by front 400 mm discs and rear 380 mm disks.
For the first time, a new optional M Drive Professional is available which has been developed specifically for track driving. It is designed to help the driver to make consistent progress in pursuit of the ideal line and the perfect lap. Features include the M Drift Analyzer which records the duration, distance covered, line and angle of a drift. Other functions include the M Laptimer, which provides a comprehensive amount of performance information, shown on both the optional Head-Up display and in the instrument cluster. As well as checking their current lap time, the driver can also keep a constant eye on how much quicker or slower they are than their fastest lap of the current session. The Control Display shows the number of laps completed so far, the distance covered and the duration of the driver’s current stint. The driver can also analyze the data recorded during their track time in detail using the BMW M Laptimer app on their Apple iPhone, which they car share on social media. Among the resources available are a bird’s-eye map view of the track, a lap time comparison, data from the car’s sensors such as speed, engine revs and accelerator position, and graphics showing the lateral and longitudinal acceleration values attained.
The new M3 and M4 are the most focused M3 and M4 models ever, according to BMW. The M-specific design features differentiate the two new cars from their non-M versions more than ever. Exclusive exterior paint colours, forged M light-alloy wheels, a carbon fibre roof and the optional M Carbon exterior package emphasise both form and function of the new BMW M3 and M4.
“The design is resoundingly function-driven, pure and reduced without compromise,” says Adrian van Hooydonk, Senior Vice President BMW Group Design. “At the same time, it provides an emotionally engaging window into the vehicle character.”
The front end of the new M3 displays the most aggressive differentiation from its non-M sibling. Like the new M4, the front end is highlighted by the large and deep frameless BMW kidney grille designed to feed the massive amounts of air needed for fulfilling the cooling requirements under the most rigorous conditions. Cooling for the engine and brakes is provided by large additional intakes on either side of the kidney grille. These two-section apertures feature brake air ducts on the inside and air supply for the remote coolant radiators to the outside. At the outer edges of the front bumper, the vertical intakes for the Air Curtains with integrated, aerodynamically effective “flics” accentuate the width of the car.
The roof of both the new BMW M3 and M4 is made from carbon-fibre-reinforced plastic (CFRP). This extremely lightweight material lowers the cars’ centre of gravity, enhancing their agility. Two fins running longitudinally over the CFRP roof optimize airflow, as does the rear spoiler, which is painted in High-gloss Black. The rear diffuser is finished in black and frames the familiar exhaust system’s twin pairs of 100 mm exhaust tips. The slim, darkened rear light clusters with L-shaped LED taillights extend into the fenders, further accentuating the width of the two new models.
Canadian MSRP pricing starts at $84,300 for the M3 Sedan, $88,300 for the M3 Competition Sedan, $85,100 for the M4 Coupe and $89,100 for the M4 Competition Coupe.
