  • cylinder  M  TwinPower  Turbo  engine   with 431hp and impressive 550Nm torque  across a very wide rev range.
  • Extensive  use  of lightweight materials,  including carbon-fibre, for substantial weight loss over the outgoing model.
  • Dynamic  driving  technologies include  Active M Differential, Adaptive  M  suspension  and   optional   M  Double Clutch
  • Extensive  standard equipment  and  connectivity;  wide  range of options.
  • Launches 21 June 2014 at £56,175 OTR for the M3 Saloon and £56,635 OTR for the M4 Coupé.


The launch of the new BMW M3 Saloon  and new BMW M4 Coupé heralds  the arrival of the fifth-generation of the iconic high-performance sports car from BMW M. For the first time the Coupé and Saloon models receive individual model names, in deference to the different model series that provide their basis.

Another first is the adoption of a turbocharged engine for this BMW M model: the high-revving, 3.0-litre six-cylinder in-line engine  with M TwinPower  Turbo technology has been specifically developed for this purpose, and produces a maximum output  of 431hp. Its peak torque  of 550Nm is available across a very wide rev range  starting  at just 1,850rpm, and exceeds the figure recorded by the outgoing BMW M3 by roughly 40 per cent. In spite of this, the new engine  also achieves a reduction in fuel consumption and emissions of around  25 per cent.


To maximise dynamic ability and ensure excellent efficiency, a weight loss of over 80kgs has been achieved compared to a comparably equipped predecessor model. Specific weight-saving measures include the increased use of lightweight materials: both models now feature  a carbon-fibre reinforced plastic roof.

BMW M engineers have paid particular attention to the car’s aerodynamic performance, and incorporated the latest Active M Differential amongst numerous other technical highlights. During the development process the engineers worked closely with BMW Motorsport’s professional racing drivers, with extensive  testing and set-up work carried out on the Nürburgring Nordschleife circuit.

The balance of the overall concept: high  power, low weight, driving pleasure.

The new BMW M3 Saloon and new BMW M4 Coupé are formed from a host of finely blended elements, all working in perfect harmony  to deliver outstanding performance, precision and agility on road and track.

With the new BMW M3 Saloon and M4 Coupé, the engineers sought to optimally channel  the air around  the car in the quest for ultimate performance, while also ensuring the engine,  powertrain  and brakes  receive the requisite cooling. Even when operating under  heavy loads on the racing circuit. The aggressively styled front apron, smooth under-body and the clearly defined  lip spoiler at the rear of the M3 Saloon (or integrated bootlid spoiler at the rear of the BMW M4 Coupé)  reduce lift by an equal amount at the front and rear axle, to the benefit of handling.

Albert Biermann, Head of Development at BMW M GmbH, said: “The way in which we channel the inflowing air through  the engine oil cooler creates a venturi effect, which reduces front axle lift and, in so doing, improves the steering.”

The Aero Curtain and M side gills, the latter with integrated Air Breathers minimise turbulence in the front wheel arches. These elements, together with the aerodynamically optimised side mirrors in familiar M twin-stalk style, are not only distinctive design features, they also help to reduce drag.


The new six-cylinder in-line engine: high-revving, turbocharged unit combines the  best of both worlds.

The new BMW M3 Saloon and new BMW M4 Coupé mark a return to thegenerations of this iconic sports car.

The new engine  sees a slight power upgrade over the previous V8 to 431hp, now delivered between 5,500 and 7,300rpm, with maximum revolutions set at an unusually high figure for a turbocharged engine: 7,600rpm. Peak torque  has been increased by roughly 40 per cent to 550Nm, and is maintained over a very 62mph takes  both cars just 4.3 seconds with manual transmission, or just 4.1 seconds with the optional M DCT, while the top speed is 155mph (electronically limited). The new powerplant also boasts excellent fuel economy: the combined consumption incompliant.

The M TwinPower  Turbo technology comprises two fast-responding mono- scroll turbochargers, High-precision direct injection, VALVETRONIC variable valve timing and Double-VANOS continuously variable camshaft timing. VALVETRONIC and Double-VANOS work in tandem to seamlessly control intake valve lift. The result is a smooth and efficient power delivery, with very sharp response and reduced fuel consumption and emissions.

The six-cylinder engine  features a closed-deck crankcase design, which is very rigid and allows cylinder pressures to be increased for improved power output. And instead of liners, the cylinder bores  feature  a twin-wire arc- sprayed coating, which results  in a significant reduction in engine  weight.

A further technical  highlight is the forged, torsionally rigid crankshaft which, as well as providing increased torque-carrying capacity, is also lighter in weight. This significantly reduces rotating masses, resulting in improved throttle response and acceleration.

A sporting engine  sound, in keeping with BMW M tradition, is ensured thanks  to the lofty rev range  of the new engine  and an innovative flap arrangement in the twin-pipe exhaust system. The electrically-controlled flaps just before  the rear silencer minimise exhaust backpressure and produce a sound that is striking and unmistakable over the entire engine  speed range, as well as giving precise feedback on engine  load.

The different selectable drive modes, programmable with the MDrive Manager and activated via the iconic steering wheel ‘M’ buttons, offer drivers a choice  of preconfigured, perfectly balanced vehicle set-ups which also feature  different engine  sound profiles.


Track-readyengine oil supply system for outstanding performance

On the track, the exceptional driving dynamics of the BMW M3 Saloon and BMW M4 Coupé place extra demands on the engine  oil supply system, the design of which reflects  the extensive motorsport experience of BMW M. The low-weight magnesium oil sump,  for example, features a special cover to limit movement of the oil under  the effects of strong  lateral acceleration. Under extreme longitudinal acceleration and deceleration, an oil extraction pump  and sophisticated oil return system situated close to the turbocharger also help to maintain stable  oil circulation. Oil is therefore supplied  continuously to all engine components in all driving situations – whether in everyday motoring  or during hard driving on the track.

Sophisticated cooling concept for maximum performance

The exceptional performance potential of the BMW M3 Saloon and BMW M4 Coupé places exacting demands on temperature management, in not only the engine  but also the peripheral assemblies. In order to ensure optimum  operating temperatures across all types  of usage, BMW M engineers have developed an extremely effective cooling system.

For example, alongside the two sophisticated turbocharger units, the air intake system of the six-cylinder engine  also includes an indirect intercooler, maximising charge pressure and engine  output.  Moreover, as well as a main radiator, the cooling system also comprises a water cooler repositioned to the side for the high and low temperature water circuits, and the engine  and transmission oil (if the M Double Clutch Transmission is specified). An additional electric coolant pump  cools the turbocharger bearing mounts when the car is stationary.

Six-speedmanual gearbox with new throttle blipping function:

The standard transmission specified is a six-speed manual gearbox  with a robust double-plate clutch. This unit is considerably more compact than its predecessor and also 12kgs lighter. To increase shift comfort, the manual gearbox  uses innovative new carbon  friction linings in its synchroniser rings. The gearbox  blips the throttle on downshifts – previously a feature  reserved for the M Double Clutch Transmission – improving the smoothness of the driving experience and helping to enhance stability.


Seven-speed M Double Clutch Transmission with Drivelogic and Launch Control

The optional transmission for the new BMW M3 Saloon and M4 Coupé is the third-generation M Double Clutch Transmission (M DCT). As well as changing gear automatically, in manual mode it enables ultra-fast  gear changes with no interruption in the flow of power. The integrated Launch Control function ensures optimum  sprinting performance off the line, producing acceleration figures that would be simply unattainable with the manual gearbox. In addition, the system allows for a range  of extra features, including Stability Clutch Control, which opens the clutch when the car is understeering to bring it back into line, and also the selectable Drivelogic modes that give the BMW M3 and BMW M4 more comfortable, more economy-focused or even sportier characteristics depending on driver choice. The additional seventh gear over the manual gearbox allows longer gear ratios – and delivers the efficiency gains you would expect  as a result.

Taking advantage of the extremely light yet impressively durable  properties of CFRP (carbon-fibre reinforced plastic), the engineers have been able to construct the driveshaft from this material.

“The impressive stiffness and low weight of the CFRP tubing allow the driveshaft to be constructed as a single-piece unit with no centre bearing. As well as a weight-saving of 40 per cent  over its predecessor, we have achieved a reduction in rotating masses and therefore improved drivetrain dynamics.” explains Albert Biermann.


The rear-wheeldrive chassis with Active M Differential

The Active M Differential makes a considerable contribution to the superb dynamics of the new BMW M3 Saloon and BMW M4 Coupé.  With further weight-savings thanks  to hollow, and hence lighter, output  shafts,  the Active M Differential uses an electronically controlled multi-plate limited-slip differential to optimise traction and directional stability. Working precisely and rapidly, the control unit links up with the DSC (Dynamic Stability Control) system and also takes  into account the position of the accelerator pedal, the rotational speed of the wheels  and the car’s yaw rate.

Every driving situation is therefore precisely analysed and an impending loss of traction on one side of the car identified at an early stage. The degree of differential lock – which may be anywhere between 0 and 100  per cent  – is adjusted as required  within a fraction of a second, enabling wheel spin to be prevented on slippery surfaces, in instances where the right and left rear wheel have widely differing friction coefficients or in tight bends and when changing direction with particular vigour.

The M Dynamic Mode – a sub-function of the Dynamic Stability Control (DSC) system – allows enthusiastic drivers to probe  the limits of the new cars while retaining an electronic safety net at all times. The system tolerates greater wheel slip and therefore easy drifting, although  DSC will still step  in if the car ventures over the limits – unless it is switched off completely.


Aluminium suspension elements ensuresharper dynamics

The core expertise of BMW M resides in developing cars that offer superb driving dynamics and real driver satisfaction, yet not at the expense of everyday usability. In order to achieve these aims with the significantly increased performance capability of the new BMW M3 Saloon and new BMW M4 Coupé, the suspension of the outgoing BMW M3 has been redesigned with painstaking attention to detail.

In the front suspension the use  of lightweight aluminium construction for components such  as control arms, wheel carriers and axle subframes saves 5kgs over a conventional steel design. Play-free ball joints and elastomer bearings developed specially for the cars ensure an optimum  and direct transfer  of forces both laterally and longitudinally, while an aluminium stiffening plate, CFRP engine strut brace  and additional bolted  joints between the axle subframe and the body structure all help to increase the rigidity of the front end.

Also lighter is the new five-link rear axle. All the control arms and wheel carriers are manufactured using forged aluminium, which reduces the unsprung masses of the wheel-locating components by around  3kgs compared with the previous model generation. The rigid connection between the rear axle subframe and the body – without the use  of elastic rubber  elements – is borrowed from motorsport and serves to further improve wheel location and therefore directional stability.

Tyre development was critical from the outset, and both cars feature  19-inch wheels as standard for the UK market, in either Ferric Grey or optionally Jet Black. These specially developed forged wheels  make a significant contribution to the reduction in the cars’ unsprung masses. BMW M engineers have taken great care to ensure all the components between the steering wheel and tyres work together harmoniously  and therefore provide maximum driving precision and lateral stability, while retaining good ride comfort.

Electric Power Steering with three settings

The electromechanical steering system in the new BMW M3 Saloon and new BMW M4 Coupé represents a new development from BMW M. The integrated M Servotronic function electronically adjusts the level of steering assistance according to the car’s speed. The system offers the driver three  settings as standard, which can be selected at the touch  of a button: COMFORT,  SPORT and SPORT+ modes allow the level of steering assistance to be adapted to suit any given situation and the driver’s personal tastes.

The Adaptive M suspension, fitted as standard for the UK market, also provides COMFORT,  SPORT and SPORT+ modes, enabling the driver to choose between a more comfortable damper setting for urban driving, for example, or a stiffer set-up for dynamic driving on country roads. A third option minimises body movements and maximises dynamic performance for use on the track.

The standard new BMW M Compound brakes  boast impressive feel, outstanding stopping power and a high resistance to fade. Far lighter than conventional equivalents, they contribute to a substantial reduction in unsprung masses. Even lighter BMW M Carbon  ceramic brakes  can be specified as an option – gold callipers denote their fitment.


Lightweight engineering: shedding weight in all the  right places.

Intelligent lightweight design was a top priority in the development of the BMW M3 Saloon and BMW M4 Coupé.  The goal was to minimise kerb weight in order to give both models outstanding driving dynamics and exemplary efficiency. These measures have delivered impressive results,  with the BMW M4 Coupé (manual transmission) weighing 1,497kgs, around 80kgs lighter than a comparably equipped predecessor model – with all the benefits that reduction brings.

On the outgoing models,  the CFRP roof was confined to the Coupé version. Now, for the first time, the four-door  BMW M3 Saloon gets  this striking design and functional feature  as standard. The CFRP roof brings weight-savings of 5kgs in the case of the BMW M3 Saloon and more than 6kgs in the case of the BMW

M4 Coupé.  It also lowers the vehicle’s centre of gravity, which has a positive impact on driving dynamics.

Aluminium is used for the front wings and the bonnet, as opposed to conventional steel, and makes an important contribution to the low overall weight, while at the same time improving axle load distribution.

On the M4 Coupé, the shape of the new bootlid has been optimised for aerodynamic performance, while the use of a carbon-fibre and plastic compound saves additional weight.

The new BMW M3 Saloon and new BMW M4 Coupé also feature  a CFRP driveshaft. The high rigidity and low weight of the CFRP tube mean  that the driveshaft can be produced as a single-piece component, without a centre bearing. This achieves weight-savings of 40 per cent  over the previous model and a reduction in rotating masses, which in turn results  in more dynamic powertrain  response.

A further use  of CFRP can be found in the engine  compartment for the engine strut brace.  Weighing only 1.5kgs  it offers superior  rigidity to a comparable aluminium component, and at the same time plays a key part in the excellent steering response and precision of both vehicles. The use of carbon-fibre in these models is a reminder that BMW is a global leader in high-strength, lightweight CFRP construction, and that it was BMW who brought out the first mass-production vehicle with a body consisting entirely of this material – the innovative BMW i3.

Design: striking use of forms underlines standout performance capability.

“The superior  performance of the BMW M3 Saloon and BMW M4 Coupé should be obvious at first glance,” explains Karim Habib, Head of Design at BMW Automobiles. “Indeed, the exterior design has a visual impact that elevates the BMW M design language to a new level of expression, highlighted by a purposeful character, emotional  appeal  and dynamic verve.”

Viewed from the front, the BMW M3 Saloon and BMW M4 Coupé have a powerfully expressive ‘face’, with a modern take on the twin headlight arrangement and a distinctive double-slat kidney grille with M designation. The aggressive front apron, with its trio of large intakes, supplies cooling air to the engine  and brakes.  Among the other hallmark BMW M design features is the characteristic powerdome on the bonnet, which hints at the potential of the muscular M TwinPower  Turbo engine  and creates space for the intercooler. The twin-stalk side mirrors are another classic BMW M design feature.

The sides of both cars clearly show the hallmark BMW proportions of a long bonnet, long wheelbase, set back glasshouse and short front overhang,  further emphasised by familiar M design elements. The new M side gills perform both a stylistic and a functional role: integrated into them  are Air Breathers, which team up with the Aero Curtains in the front apron to help optimise the airflow around the wheel arches and therefore improve aerodynamics.

The dark colour of the CFRP roof (with its contoured roofline) gives both models a lower-slung and more compact appearance, as the eye perceives the roof pillars – painted in body colour – to be the uppermost point of the car. A flowing roofline then gains in momentum once  again as it heads rearwards, increasing aerodynamic downforce and giving the rear a more muscular look at the same time.

At the rear, there  are greater differences in the two models. The BMW M3 Saloon is fitted with a lip spoiler to reduce lift, while the tailgate of the BMW M4 Coupé features an integrated rear spoiler and is made from a carbon-fibre compound.

Both models feature  prominently flared rear wheel arches, which, in combination with the wide track, give the cars a very purposeful stance. The high-gloss pair of twin exhaust tailpipes are framed by the sculptural  rear apron with its integrated diffuser.


Interior design: flawless ergonomics in a sporting ambience.

Inside, drivers will be greeted by the interior architecture prioritising unimpeachable ergonomics and a clear driver focus. However, the emphasis has naturally been put on an even more sporting ambience. There  are a host of traditional BMW M equipment details, including M door sill finishers, M gearshift  lever, M design circular instruments with white graphics,  M leather steering wheel (with M logo, chrome trim and iconic triple-colour contrast stitching) and metallic shift paddles (if the M DCT gearbox  is specified). The BMW Individual headlining is finished in Anthracite.

The bespoke front seats take inspiration from the bucket seats fitted in racing cars, and feature  a full-size single-piece back panel. This means the construction of the seats is very flat, while the high, width-adjustable side bolsters and low-set seat  surface allow an ideal seating position and provide excellent support.
Despite this, these BMW M seats also include electric adjustment and heating as standard. On the seat  surface,  the stitching, upholstery segmentation and perforation lend the seats a slim-fitting feel, whilst the BMW M logo on the seat is illuminated for the first time.

Like the front seats, the distinctively contoured backrests of the rear seats also offer exceptional lateral support: they are made from a lightweight composite material and can be folded in a 60:40 split. This gives the BMW M3 and BMW M4 a level of everyday usability that is well beyond the norm for high- performance sports cars.

Equipment: extensive standard equipment joined by a host of options that  enhance dynamics and comfort.

The new BMW M3 Saloon and new BMW M4 Coupé possess an extensive list of standard equipment, which reflects  their performance-oriented character but also their excellent everyday usability. The UK specification has been enhanced substantially from the predecessor model with a number of additions; these

include technical features such  as Adaptive M suspension, 19-inch M light alloy wheels and front and rear PDC; comfort items such  as the heated and electric BMW M seats and exterior-folding mirrors; aesthetic features such  as High-gloss Shadowline exterior trim and finally the full BMW Professional Media package with upgraded Bluetooth system.

In addition, customers can choose from a broad range  of optional equipment to give the cars either an additional sporting edge, or boost comfort levels further still. For those buyers  wishing to personalise their cars yet further, the wide- reaching spectrum of BMW Individual – including BMW Individual paint finishes, BMW Individual Merino leather and BMW Individual interior trim elements – will be available later in 2014.

Further options for comprehensive driver information

For track drivers BMW M has developed a free BMW M Laptimer app, which allows owners  to analyse  their personal driving style. Once  their smartphone is hooked up to the car – via USB cable or the car’s snap-in adapter – customers can operate the BMW M Laptimer app easily using the iDrive Touch  Controller. The app then records speed, longitudinal and lateral acceleration, engine  revs, the gear engaged, steering angle, accelerator position and fuel consumption. The data can subsequently be analysed via graphic displays on the customer’s smartphone, including the driver’s reactions. Another feature  allows two recordings on the same circuit to be compared corner-by-corner: the readings can be either the driver’s own or data shared via email.

Naturally, the BMW M3 Saloon and BMW M4 Coupé are also available with the wide variety of driver assistance systems and mobility services introduced under the BMW ConnectedDrive banner,  some of which will already be familiar from the BMW 3 Series and BMW 4 Series. Among the highlights are the latest- generation of the Professional Navigation system, offering extra capability, sharper graphics and 3D elements for the map display; Driving Assistant Plus, which warns the driver of a looming collision with a pedestrian; Adaptive full LED headlights with an intelligent anti-dazzle High-beam Assistant and a further developed version of Active Cruise Control with Stop  & Go function.

The optional M Head-up Display comes with additional, M-specific functions such  as a gear display, rev counter and Optimum Shift Indicator.
