BMW X5 M
Now the discerning customer has the opportunity to enjoy the unique high-performance character of a BMW M car also in the segment of BMW X models: The BMW X5 M and the BMW X6 M are the first all-wheel-drive models to offer the supreme performance, dynamic driving features, athletic design, and premium quality of a typical BMW M Car.
Both models are powered by a newly developed V8 high-performance engine delivering 408 kW/555 hp at an engine speed range between of 6,000 rpm from an engine capacity of 4,395 cc. The new M TwinPower Turbo engine is indeed the world's first power unit with a common exhaust manifold encompassing both rows of cylinders and featuring Twin Scroll Twin Turbo Technology.
BMW's intelligent xDrive all-wheel-drive system is naturally geared to the specific power and performance characteristics of the BMW X5 M, just like Dynamic Performance Control also standard on both models. Interacting with the cars' special M suspension including Adaptive Drive and the newly developed Servotronic power steering, this ensures the driving behavior so characteristic of a BMW M Car, combining unique driving stability with precisely controlled steering qualities all the way to the highest level of driving dynamics.
The BMW X5 M set new standards in this segment of high-performance models in terms of acceleration, lateral dynamics, steering behavior, stopping power, and efficiency. Both models accelerate to 100 km/h from a standstill in 4.7 seconds and stand out not only through the truly impressive delivery of power by the V8 turbo engine providing maximum torque of 680 Newton-metres or 501 lb-ft in the broad speed range between 1,500 and 5, 650 rpm, but also through the likewise smooth and consistent build-up of lateral forces meeting the highest requirements and the most dynamic level of performance in bends.
Power and performance typical of BMW M is delivered by the power unit in the BMW X5 M by a new design and construction principle: The new M TwinPower Turbo with Twin Scroll Twin Turbo Technology and the exhaust manifold extending over both rows of cylinders patented by BMW offer absolutely extreme response and spontaneity, a linear build-up of engine power, and an unusually consistent torque curve.
The two turbochargers are positioned together with the catalytic converters in the V-section between the two rows of cylinders. The position of the intake and exhaust ducts provided in this way serves to reduce the length of the pipes and manifolds and increase their cross-section, with pressure losses on the exhaust side being significantly minimised in the process.
The joint flow of exhaust gas provided by the common manifold system connecting two cylinders at a time also ensures optimum gas throughput. The separation of exhaust flow is continued until the exhaust gas reaches the turbine wheel, building up ongoing pressure on the two Twin Scroll Turbochargers not impaired by any kind of counter-pressure.
With maximum charge pressure amounting to 1.5 bar, the use of Twin Scroll Twin Turbo Technology with its inter-cylinder exhaust manifold makes unique use of the turbocharging potential.
Immediate, direct response to the gas pedal and truly exceptional pulling force from the engine starting at low speeds and continuing consistently to the highest load level characterize the new M TwinPower Turbo from BMW M GmbH. The truly impressive development of power ensured in this way is accompanied by fascinating engine sound accentuating the fast-revving engine characteristics and the linear build-up of power by a supreme acoustic effect typical of a BMW M Car.
Reflecting the superior power of the engine, the V8 power unit comes with a cooling system developed specifically for the two new models. One special feature in this context is the indirect intercooling effect serving to optimise performance under particularly dynamic driving conditions.
The outstanding success of BMW's intelligent xDrive all-wheel-drive technology is based on the fact that the system not only improves traction on rough terrain, but also enhances driving dynamics on the road. Electronically controlled, variable power distribution to the front and rear axle prevents even the slightest tendency to over- or understeer right from the start, before DSC Dynamic Stability Control is even required to cut in.
Dynamic Performance Control presented for the first time in the BMW X6 and now featured also in the BMW X5 M and the BMW X6 M enhances driving stability in demanding situations. Variable distribution of drive power between the right and left rear wheel significantly improves steering precision and tracking stability at all speeds, with DSC being required to stabilise the vehicle only under high lateral acceleration.
Ultimately this offers the driver an unparalleled standard of dynamic performance, agility and traction re-defining all existing benchmarks in drivetrain and suspension technology.
