BMW X4 M40I 2016
BMW X4 M40I
With the introduction of the new BMW X4 M40i, the successful BMW X4 series has gained a new top model. In the Sports Activity Coupe segment (SAC), the BMW X4 M40i is setting new standards with even more keenly honed driving dynamics, a high degree of emotionalism and singular exclusivity.
Distinctive look
The exterior of the new BMW X4 M40i demonstrates clearly the high standards set by BMW M Performance automobiles. Exclusive accents of colour on the front of the vehicle and the side mirrors finished in metallic Ferric Grey as well as the exclusive 20-inch M light-alloy double-spoke wheels with the Ultra High Performance tyre mix (optional) and the sports exhaust system with valve control and Chrome Black tailpipes on both sides emphasize the unique character of the new BMW X4 M40i. In the interior too, the typical character of the BMW M is always present. The M leather steering wheel, the M gear shift lever, the sport seats and model-specific door sills provide a foretaste of imminent driving pleasure, just like the "X4 M40i" digital lettering on the instrument cluster.
Powerful and economical
A newly developed M performance TwinPower Turbo inline six-cylinder petrol engine celebrates its world premiere in the new BMW X4 M40i. This petrol engine delivers 265 kW/360 hp at between 5,800 and 6,000 rpm from its three-litre capacity, providing a maximum torque of 465 Nm (combined fuel consumption: 8.6 l/100 km; combined CO2 emissions: 199 g/km). With this high-performance engine and the advanced M Performance TwinPower Turbo technology, the BMW X4 M40i accelerates in less than five seconds to 100 km/h and can reach a top speed of 250 km/h (electronically limited).
Superior driving dynamics
The specially tuned sports chassis of the new BMW X4 M40i provides driving dynamics at an advanced level. Stronger springs and stabilizers, increased camber on the front axle, the adaptive dampers specifically tuned to M Performance specifications and the BMW xDrive four wheel drive system with its rear wheel-drive characteristics including Performance Control, ensure a neutral self-steering response as well as a reduced roll tendency and guarantee a maximum of driving pleasure.
Sporty credentials combined with everyday practicality
The new BMW X4 M40i is the latest addition to the M Performance family and illustrates once again the long-standing expertise of BMW M in the construction of exclusive sports automobiles, which traces its origins back to the year 1972. BMW Motorsport GmbH, as it was called in those days, set new standards in international automobile racing. Highlights include the spectacular mid-engine BMW M1 sports car, which excelled in the unique Procar racing series. In addition, BMW Motorsport GmbH developed the first turbo engine with which a formula 1 world championship title was won, and with the BMW M3 created the most successful racing touring vehicle in the world in Group A to date.
Expertise gained on the race track
Since 1993, this 100% subsidiary of BMW AG has been known as BMW M GmbH. The products and services from the five divisions of BMW M Automobiles and BMW M Performance Automobiles, BMW Individual, M Equipment and Packages, BMW Group Driving Experience, as well as Security, Emergency and Special-Purpose Vehicles are aimed at customers who place high demands on their automobile in terms of performance, exclusivity and individuality. The letter M is synonymous throughout the world with success in motor sport, as well as with the fascination for highperformance sports cars driven on the road.
"BMW M Performance automobiles are constructed exclusively by BMW M GmbH and are positioned between the BMW top models and our M core models. We developed them for customers who, although they place great demands on sporty handling characteristics, are unwilling to forego the practicality of their vehicle in everyday situations. The experience and expertise gained by BMW M on the race track and in the development of high-performance sports cars has also been channelled into the development of BMW M Performance automobiles. Since the introduction of this new product category in 2012, demand has steadily increased. In 2013, around 14,250 BMW M Performance models were sold. In 2014 it was 24,000 vehicles," says Frank van Meel, Chairman of the Board of Management of BMW M GmbH.
Drive units
The newly developed M Performance TwinPower Turbo in-line six-cylinder petrol engine for the new BMW X4 M40i combines high performance with exemplary fuel economy. Accordingly, the lightweight, thermodynamically optimised aluminium engine has been constructed with what is known as a closed-deck design. In this type of construction, the water jacket surrounding the cylinders is sealed at the top, which endows the crankcase with an exceptionally high degree of stiffness.
BMW M3 and M4 engine components
The drive unit powering the new BMW X4 M40i is based upon the three-litre, in-line six-cylinder engine in the BMW X4 xDrive35i. In order to fulfil the exacting dynamic demands placed upon BMW M Performance vehicles in all respects, our development engineers have optimised the drive unit using a forged steel crankshaft in addition to components from the high-performance engine fitted to the BMW M3 and BMW M4, which were introduced in 2014. This is how, among other things, pistons with an adapted top ring, crankshaft bearings and high power spark plugs found their way from the six-cylinder inline engine with M TwinPower Turbo technology to the new BMW X4 M40i.
In addition to a higher level of charging pressure and an increase in the amount of fuel injected, the engine has been fitted with an aerodynamically tuned air intake manifold as well as an exhaust system optimised both in terms of back pressure and sound characteristics in order to further increase performance. A separate oil cooler guarantees that the optimum operating temperature of this extremely powerful engine is maintained under all driving conditions.
An exhaust system with intelligent valve control
The distinctive exhaust system fitted to the new BMW X4 M40i is unmistakable with tailpipes on both sides finished in fine Chrome Black. The radical technical changes include, in addition to intelligent valve control, a back pressure-optimized double-flow exhaust system fitted beneath the floor of the vehicle, as well as resonator tuning specific to M Performance. The result is a charismatic sound, individually determined by the driver depending on driving mode and driving situation, perfectly emphasizing the car's sporty character acoustically.
