  • A sporty chassis specifically tuned to M Performance specifications.

Press Release Woodcliff Lake, N.J.: September 30, 2015 6:00 pm EDT /3:00 pm PDT… Today, with the introduction of the new 2016 BMW X4 M40i, the successful BMW X4 has gained a new top model. In the Sports Activity Coupe segment (SAC), the BMW X4 M40i is setting new standards with enhanced driving dynamics and best-in-segment acceleration. The new BMW X4 M40i will be available at dealers starting February 2016.

Design.

The exterior of the new BMW X4 M40i makes it stand out as a clear member of the BMW M Performance family. Exclusive Ferric Gray metallic accents on the front of the vehicle and side mirrors, as well as the exclusive 20-inch M light-alloy double-spoke wheels with optional Michelin Pilot Super Sport tires and the sport exhaust system with valve control and Black Chrome tailpipes on both sides emphasize the unique character of the new BMW X4 M40i. The M leather wrapped steering wheel, M gear shift lever, sport seats, model-specific door sills and “X4 M40i” digital lettering on the instrument cluster decorate the interior, assuring immediate recognition as a BMW M Performance model.

A world premiere – the 6 cylinder inline engine.

A newly developed M Performance TwinPower Turbo inline 6 cylinder gasoline engine celebrates its world premiere in the new BMW X4 M40i. This engine delivers 355 hp at between 5,800 and 6,000 rpm from its three-liter displacement, providing a maximum torque of 343 lb-ft. With this high-performance engine and the advanced M Performance TwinPower Turbo technology, the BMW X4 M40i delivers best-in-class acceleration, running the sprint from 0-60 mph in just 4.7 seconds.

The specially tuned sports chassis of the new BMW X4 M40i provides excellent driving dynamics at an advanced level with stronger springs and stabilizers, increased camber on the front axle, and adaptive dampers specifically tuned to M Performance specifications. The BMW xDrive all-wheel drive system has been recalibrated with more power routed to the rear wheels during normal operation. The Performance Control ensures a responsive steering with more road feedback as well confident dynamics due to a specific tuning of the steering

The newly developed M Performance TwinPower Turbo inline 6 cylinder gasoline engine for the new BMW X4 M40i combines high performance with exemplary fuel economy. Accordingly, the lightweight, thermodynamically optimized aluminium engine has been constructed with 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.

Building on heritage: The BMW TwinPower Turbo engine.
The drive unit powering the new BMW X4 M40i is based upon the three-liter, inline 6 cylinder engine in the BMW X4 xDrive35i. The chassis has been optimized using a forged steel crankshaft, pistons with a modified top ring, crankshaft bearings and high performance spark plugs in its 6 cylinder inline engine with M TwinPower Turbo technology.

In addition to a higher level of turbo boost 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 optimized both in terms of back pressure and sound characteristics in order to enhance performance. A separate oil cooler guarantees that the optimum operating temperature of this extremely powerful engine is maintained under all driving conditions. 
The distinctive exhaust system fitted to the new BMW X4 M40i is unmistakable with tailpipes on both sides finished in Black Chrome. The radical technical changes include, an 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 powerful sound, individually determined by the driver depending on driving mode and driving situation, perfectly emphasizing the car's sporty character acoustically.

M Performance TwinPower Turbo technology. 
The new M Performance TwinPower Turbo inline 6 cylinder gasoline engine also benefits from TwinScroll Turbo technology, the High Precision Injection system, the Double VANOS variable camshaft control system and VALVETRONIC, the fully variable valve control system as standard equipment.

This cutting-edge drive technology in the new BMW X4 M40i guarantees the free-revving thrilling typical of a BMW M engine and its outstanding power delivery.

The integration of the turbocharger into the exhaust manifold also makes a significant contribution to the highly efficient power optimization provided by M Performance TwinPower Turbo technology in the new 6 cylinder inline engine in the new BMW X4 M40i. As internal friction is minimized, the warm-up phase required less time.

The increased camber on the double-joint front axle and the strengthening of the wishbones result in increased steering response and more steering feedback. Stiffer springs and reinforced stabilizers on both front and rear axles also reduce roll tendency and optimize driving dynamics. These measures are most effectively supported by the M Performance specific tuning, performed on the electronically controlled damping system.Excellent driving performance. 
Technical enhancements have resulted in the most powerful M Performance gasoline engine to date. The new engine powers the new BMW X4 M40i with 355 hp at between 5,800 and 6,000 rpm. This corresponds to an increase in performance of nearly 18 percent compared to the BMW X4 xDrive35i. At the same time, these internal engine modifications have increased maximum torque by a good 14 percent to 343 lb-ft between 1,350 and 5,250 rpm. The BMW X4 M40i completes the sprint from zero to 60 mph in just 4.7 seconds before hitting its electronically limited top speed of 150 mph.

The variable sports steering, sharpened by M Performance-specific tuning, delivers heightened steering precision; the steering feel is further refined by optimized road feedback.
