BMW M GmbH expanded its high-performance model line-up to include models in the mid-size Sports Activity Vehicle (SAV) and Sports Activity Coupe (SAC) segments for the first time. The BMW X3 M and BMW X4 M set the benchmark for dynamic excellence, agility and precision in their respective classes.Also new is the launch alongside the BMW X3 M and BMW X4 M of their Competition siblings. The BMW X3 M Competition and BMW X4 M Competition will capture customers' imagination with their extra power and exclusive appointments.The addition to the BMW M GmbH line-up of its first high-performance models in the mid-size Sports Activity Vehicle (SAV) and Sports Activity Coupe (SAC) segments also heralds the arrival of a newly developed sixcylinder in-line engine in two variants. The engine stands out with its familiar M high-revving character, the latest M TwinPower Turbo technology update, plus track-tested cooling and oil supply systems. It develops 353 kW/480 hp in the BMW X3 M and BMW X4 M, and an even mightier 375 kW/510 hp in the BMW X3 M Competition and BMW X4 M Competition.The standout performance characteristics of the 3.0-litre units are encapsulated by the linear power development that is such an M speciality, plus a hunger for revs quelled only by the engine's limiter. And all to the tune of an arresting soundtrack. Like the maximum output figure, peak torque of 600 Nm (442 lb-ft) also represents a new high point for a six-cylinder in-line petrol engine from BMW. The ongoing development of M TwinPower Turbo technology, coupled with the inclusion of two gasoline particulate filters and four catalytic converters, also ensures the high-performance engines can claim remarkable efficiency and exceptionally low emissions.
At the end of series development, the new BMW X3 undergoes final tuning of all chassis control and driver assistance systems at the BMW Group test centre in Miramas, southern France. The fourth generation of the Sports Activity Vehicle (SAV) in the premium mid-range vehicle segment will be presented in a few weeks' time with both highly efficient combustion engines and an advanced plug-in hybrid drive. The development and test engineers ensure that all model variants of the new BMW X3, regardless of drive concept and weight, demonstrate superior handling in every situation with an intensive tuning programme. The well-coordinated functionality of all automated driving and parking systems in the new BMW X3 also contributes to a harmonious customer experience.The new BMW X3 has already undergone extensive testing on snow and ice, in extremely hot regions and off-road on its way to series production. The SAV's suitability for everyday use and travelling was tested and refined in urban stop-and-go traffic as well as on winding country roads, highways and selected race tracks.
The in-line 6-cylinder engine in the BMW X3 M Competition and BMW X4 M Competition now features the forged lightweight crankshaft of the BMW M3 and M4 models. Its extremely torsion-resistant design enables transmission of the particularly high torque, while its low weight and reduced rotating masses also benefit the engine’s revving power. The in-line 6-cylinder engine’s racetrack-proven cooling system is designed to enable an exceptionally high level of output and includes two laterally positioned radiators in addition to the central one. There is also an additional engine oil cooler and a separate transmission oil cooler. BMW M GmbH motor racing expertise is also evident in the design of the oil supply system, which is geared towards dynamic racetrack operation. The engine’s weight-optimised oil pan has two separate chambers and an integrated suction channel. An additional suction stage enables the map-controlled oil pump to deliver lubricant from the smaller oil sump, which serves as a volume buffer. In this way, a reliable oil supply is guaranteed at all times, even during extreme longitudinal and lateral acceleration.
BMW M GmbH is refreshing the high-performance models of the Sports Activity Vehicle BMW X3 and the Sports Activity Coupé BMW X4 two years after their launch. In addition to new design features drawn from the BMW X3 and BMW X4, which have likewise been revised, along with M specific changes and a new operating concept, the new BMW X3 M Competition and the new BMW X4 M Competition also offer increased pulling power. The most powerful BMW in-line 6-cylinder petrol engine with a peak output of 375 kW/510 hp – now also used in other BMW M models – has a maximum torque which has been increased by 50 Nm to 650 Nm, enabling a 0.3-second improvement in the time required for the standard sprint from 0 to 100 km/h to 3.8 seconds. This puts the BMW X3 M Competition and the BMW X4 M Competition on a par with high-performance sports cars. The top speed is electronically cut off at 250 km/h. This limit is raised to 285 km/h in conjunction with the optional M Driver’s Package. The market launch of the new models is due to start in August 2021.
The new BMW X3 xDrive30e combines the typical qualities of a Sports Activity Vehicle with particularly efficient drive technology. The plug-in hybrid model is also characterized by agile handling and sporty driving characteristics, robust versatility, a variable interior space, premium quality and advanced networking technology. Its BMW xDrive system distributes the drive torque between the front and rear wheels at all times, even when driving purely on electric power, in order to guarantee sporty driving characteristics on the road and superior off-road performance on unpaved terrain. The drive power is generated by a 2.0 liter, 135 kW / 184 PS four-cylinder petrol engine with BMW TwinPower Turbo technology and an electric motor with an output of 80 kW / 109 PS integrated into the 8-speed Steptronic transmission. Together, the two drive units mobilize a system output of 215 kW / 292 PS. The maximum system torque of the plug-in hybrid drive is 420 Nm. The new BMW X3 xDrive30e accelerates from zero to 100 km / h in 6.1 seconds. Its top speed is 210 km / h.
