The First-Ever BMW X3M and X4M.

It's been a long time coming, but BMW's high-performance X3 and X4 models are here. Say hello to the X3 M and X4 M; each wielding some serious horsepower under the hood along with a bevy of suspension upgrades designed to put the sport in sport-utility vehicle. Or rather, sports activity vehicle as BMW prefers. Either way you cut it, these people movers can move people fast. Seriously fast.

Superior performance on every route: the BMW X3 M Automobiles accelerate pulse and driving pleasure to new heights in split seconds. Experience sports cars charged with emotion, which unite the adventurous spirit of a BMW X3 with the sporty and exclusive claim of BMW M. It is up to you: the BMW X3 M features outstanding motorsports genes and offers driving dynamics on the highest level – which are further more increased by the BMW X3 M Competition with a maximum of power and exclusivity on all roads and racetracks. The BMW X3 M40i demonstrates an extremely well-balanced interplay of performance, comfort and efficiency.

The first step in creating a proper M machine is to add power, and BMW doesn't disappoint. Under the hood of these twins is a 3.0-liter twin-turbo six, tuned to make 473 horsepower (352 kilowatts) and 442 pound-feet (600 Newton-meters) of twist. If that's not enough for your compact performance SUV needs, BMW will also offer a Competition version in both flavors that ups the ante to 503 hp (375 kW). According to the automaker, that's enough for a 0-60 mph sprint in approximately four seconds flat. Top speed is limited to 155 mph, unless you select the optional M Driver's Package which ditches the limiter. In that case, you’ll hit 174 mph flat out, or 177 in the higher-hp Competition model.

This latest incarnation of M TwinPower Turbo technology features two mono-scroll turbochargers, which supply compressed air to cylinders 1 – 3 and 4 – 6 respectively. The engine’s power output is enhanced through the use of upgraded turbo compressor wheels and a water-to-air intercooler. A flow-optimized air intake system reduces pressure losses, while an electronically controlled wastegate enhances turbo response.

The motor sport expertise amassed by BMW M GmbH also makes its presence felt in the design of the oil supply system, which is required to meet the challenges of track driving. The engine’s lightweight oil sump has two separate chambers and an integrated suction channel. An additional suction stage allows the map-controlled oil pump to draw lubricant from the smaller chamber, which steps in when extra flow is needed. This ensures a reliable supply of oil at all times, even under the most extreme lateral and longitudinal acceleration and braking forces.

The 2020 BMW X4 M is the high-performance version of BMW’s compact coupe SUV. Unveiled alongside its 2020 X3 M sibling, the X4 M arrived five years after the nameplate was introduced in 2014. A bit late to the party, but BMW finally offers a competitor for the Mercedes-AMG GLC63 Coupe. Based on the second-generation X4 that was unveiled for the 2018 model year, the X4 M shares underpinnings and technology with the X3 M. It features BMW’s brand-new S58 engine, a twin-turbo, 3.0-liter inline-six that will also power the next-generation M3 and M4 models. The X4 M is, together with the X3 M, the first M vehicle that’s available with two power ratings at the same time. The X4 M is the base model with 473 horsepower, while the X4 M Competition acts as the range-topping version with 503 horsepower.

Just like other M models, the X4 M is heavily based on the standard X4 design-wise. It features the same new headlamps that no longer run into the grille, taller kidney grille, and the reshaped engine hood seen on the second-generation crossover. Down below, there’s a new M bumper with large, deep air intakes and big intercoolers that feed air into the turbocharged engine, as well as a significantly bigger vent in the center. The latter has sharper, more angular edges and a wider middle section that extends toward the sides. Like any M model out there, the kidney grille has black painted vertical slats instead of chrome. These come standard on the X4 M, but the frame remains chromed. Go with the Competition version and the entire grille is finished in gloss black. The bumper trim is identical for a more aggressive look.

A design that radiates sheer dynamism: at the front and rear ends and inside, too, exclusive design elements and athletic proportions refer to the sporty ambitions of the BMW X4 M40i.
