Every generation of the BMW M3 has incorporated a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were constructed) droptop model. The convertible grew to become more widespread on the successive generations, with the hardtop-convertible E93 being the most latest. Considering this history, there appeared very small doubt that as the M3 grew to become the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its international debut at the 2014 New York Auto Present, the 2015 BMW M4 Convertible functions, like its forbearers, every little thing that is wonderful about the hardtop variant while incorporating an unlimited amount of head room. That means the exact same 3.-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight 6 sits under its domed hood, although either a 6-velocity stick or a 7-pace M dual-clutch transmission dispatches power to the excess fat rear tires.
As for specific variations in between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a 6-pace manual guidelines the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 lbs. Feel it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal excess weight reduction from the third-generation convertible to the 4th is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.
While we are not crazy about 4,000-plus-pound auto, BMW claims that cargo area has increased as properly. Like the excess weight cost savings, even though, the added volume is negligible. There’;s 13 cubic feet of trunk room when the roof is up, an improve of .6 cubic feet and 7.8 cubic feet of space when the 3-piece leading is stowed. As is the trend with convertibles today, the roof can be lowered in twenty seconds and at speeds up to eleven miles per hour.
Revenue of the 2015 BMW M4 kick off this summer season. We’;ll have considerably more on the newest addition to BMW’;s M assortment when it debuts in a number of weeks, at the 2014 New York Automobile Present. Right up until then, you can take a search at the total gallery of photos of the M4 at the prime of the webpage. You can also scope out BMW’;s official press release by scrolling down.
Legendary top-down motoring from BMW M
Woodcliff Lake, NJ – April 3, 2014 6:00pm EDT/3:00pm PDT. . . The all-new BMW M4 Convertible arrives in US showrooms late this summer season to join the M4 Coupe and M3 Sedan. The 2015 BMW M4 Convertible is powered by the identical BMW M TwinPower Turbo 3.-liter inline-6 as its siblings. That engine produces 425 horsepower and 406 lb-ft of torque and can be mated to either a 6-pace manual or 6-speed M-DCT transmission. The new BMW M4 Convertible can make its globe debut at the 2014 New York International Car Show.
The new inline-6 M engine: High-revving, turbocharged unit combines the very best of both worlds. Like the new BMW M3 Sedan and new BMW M4 Coupe, the new M4 Convertible sees a return to an inline-6 engine, as utilised on the 2nd and third generations of this iconic open sports automobile. The new turbocharged engine combines the best of the 2 worlds – reaching a maximum 6,600 rpm, it is unusually high-revving for a turbocharged engine, resulting in linear electrical power delivery above a broad engine velocity variety and a soulful engine note, although M TwinPower Turbo technology guarantees that peak torque is on tap more than a broad rpm variety. A even more hallmark of this engine is its excellent efficiency.
The new engine sees a power upgrade over the prior V-8 to 425 hp, which is delivered in between 5,500 and 6,300 rpm. Peak torque has been enhanced by approximately 40 % to 406 lb-ft, and is maintained more than a extremely wide rev band (1,850–5,500 rpm). The sprint from zero to 60 mph takes the new BMW M4 Convertible just 4.4 seconds with the 6-speed manual. Equipped with the 7-speed M Double Clutch Transmission, this quantity falls to 4.2 seconds. Prime velocity is 155 mph (electronically limited). The BMW M TwinPower Turbo engine hits highest revs of 6,600 rpm, in retaining with the normally substantial-revving character of M engines.
The M TwinPower Turbo technological innovation comprises 2 quickly-responding mono-scroll turbochargers, Higher Precision Direct Injection, Valvetronic variable valve timing and Double- VANOS constantly variable camshaft timing. Valvetronic and Double-VANOS operate in tandem to seamlessly handle consumption valve lift. The result is smooth and productive power delivery, extremely sharp response and decreased fuel consumption and emissions.
The 6-cylinder engine characteristics a closed-deck crankcase design and style which is very rigid and enables cylinder pressures to be improved for enhanced electrical power output. And as an alternative of liners, the cylinder bores function a twin-wire arc-sprayed coating, which benefits in a substantial reduction in engine bodyw7
Engine fat is more reduced by the forged, torsionally rigid crankshaft which, as properly as saving bodyweight, also supplies elevated torque-carrying capability. This substantially lowers rotating masses, resulting in improved throttle response and acceleration.
Progressive technologies delivering best-level efficiency.
Energy transfer in the BMW M4 Convertible is via a normal 6-velocity guide gearbox. Available as an alternative is the 6-pace Double Clutch Transmission M-DCT, which permits the driver to alter gears not only utilizing the selector lever in the center console but also by way of the shift paddles on the steering wheel. This transmission properly combines 2 gearboxes, each and every with its own clutch. This indicates gear changes are executed with no interruption in the flow of energy – and the shift processes are consequently shorter. Drivelogic enables the driver to pick from diverse shift modes, which see the M4 Convertible adopting a notably comfort-oriented, economy-targeted or ultra-sporty technique to gear adjustments when in automated mode. The Launch Manage function also integrated into M-DCT allows optimum acceleration off the line.
The regular Lively M Differential optimizes traction at the rear axle. The electromechanical steering technique, meanwhile, represents a new growth from BMW M GmbH and is the crucial part in the website link among driver and auto. It gives the gifts of direct steering feel and exact suggestions. The integrated Servotronic perform electronically adjusts the level of steering support according to the car’;s velocity, supplying optimum steering characteristics at all speeds. 3 steering settings (COMFORT, SPORT and SPORT+) can be chosen at the touch of a button to adjust the degree of steering assistance to the situation at hand and to the driver’;s individual tastes.
The optional Adaptive M suspension likewise comes with COMFORT, SPORT and SPORT+ modes. The BMW M4 Convertible is equipped as regular with M compound brakes, but consumers can also purchase their auto with even lighter and much more efficient M carbon ceramic brakes, which boast the additional visual highlight of gold-painted calipers.
Light-weight design across the board: Shedding bodyweight in all the right locations.
As well as outstanding dynamic qualities, intelligent light-weight layout also makes it possible for the BMW M4 Convertible to claim exemplary efficiency. Its substantial fat-saving measures produce a curb bodyweight of just 4,055 lbs – about 90 pounds much less than its predecessor.
Between the key contributors here are the aluminium front fenders and hood, with light-weight aluminium building also a characteristic of the chassis. Comprehensive use is also created of a materials that is both light-weight and really stiff, and therefore sturdy: carbon-fiber- reinforced plastic (CFRP). The new BMW M4 Convertible also attributes a CFRP drive shaft. The higher rigidity and lower weight of the CFRP tube suggest that the drive shaft can be made as a single-piece element, with out a center bearing. This achieves weight cost savings of 40 % above the previous model and a reduction in rotating masses, which in flip outcomes in much more dynamic powertrain response.
The CFRP strut brace in the engine compartment is a more example of how all bodyweight- conserving measures on these automobiles have also been tailored to the improvement of driving dynamics. Weighing only 3.3 lbs, the strut brace offers superior rigidity to a comparable aluminum element and at the identical time plays a crucial component in the outstanding steering response and precision of the 2 cars.
The use of carbon is a reminder that BMW is a global leader in large-strength, light-weight CFRP construction, and that it was BMW who brought out the very first mass-manufacturing car with a physique consisting fully of this material – the progressive BMW i3.
Layout: the powerfully expressive encounter of BMW M.
Viewed from the front, the BMW M4 Convertible stands out most prominently with its powerful contours and a strongly defined 3-dimensionality, which lends it a powerfully expressive encounter. Characteristic design components depart no doubt that this auto is the function of BMW M. There is the contemporary get on the twin headlight arrangement (with optional LED technology), for instance, not to mention the distinctive twin-bar kidney grille with black painted grille bars – which reflect the layout of the characteristic BMW M double-spoke wheels and bear the M brand – and the powerfully developed front apron with its trio of massive intakes supplying cooling air to the higher-functionality engine and brakes. Between the other hallmark BMW M design functions on display is the characteristic power dome on the hood, which hints at the potential of the brawny M TwinPower Turbo engine and generates room for the intercooler. And the striking exterior mirrors, with their recommended twin-stalk mounts, optimize the aerodynamics of the new BMW M4 Convertible.
The flanks: lower-slung silhouette and dynamic lines.
The profile of the M4 Convertible extends the dynamic impression created by its front finish. The hallmark BMW proportions of a prolonged hood, extended wheelbase, set-back glasshouse and brief front overhang are lent further emphasis by familiar M design and style elements.
Those dynamics-accentuating particulars contain likewise newly designed M gills, which carry out the 2 a stylistic and a functional function. Integrated into them are Air Breathers, which staff up with the Air Curtains in the front apron to support optimize the airflow around the wheel arches and consequently improve aerodynamics.
The interior layout: flawless ergonomics in a sporting ambience.
Climbing into the BMW M4 Convertible, drivers will be greeted by an interior architecture complete with unimpeachable ergonomics and clear driver emphasis. In trying to keep with its character, however, the interior fulfils an even more sharply defined sporting quick. To this finish, the host of standard BMW M equipment specifics includes M door sill finishers, an M driver’;s footrest, M gearshift lever, M-style circular instruments with white graphics, M leather steering wheel with chrome trim, colour contrast stitching and electroplated-appear shift paddles (if the M-DCT gearbox is specified).
The front seats also represent an evocative expression of BMW M’;s motor sport genes. Taking visual inspiration from the bucket seats fitted in racing vehicles, the seats function a complete- dimension single-piece back panel. This signifies the construction of the seats is really flat, although the higher, width-adjustable side bolsters and lower-set seat surface allow an excellent seating place and offer exceptional support. Regardless of their undeniably sporty design and style, the BMW M sports activities seats are equipped with comfort-enhancing functions like electric adjustment and heating. On the seat surface, the stitching, upholstery segmentation and perforation lend the seats a slim-fitting feel. Illuminated for the initial time, the BMW M brand on the seat backrests adds a new and unique highlight.
Interior with exquisite resources and motor sport ambience.
The BMW M4 Convertible stands out with an interior that is unique and practical in equal measure. For illustration, the M Sport leather multifunction steering wheel is standard, as are bucket-design M sports seats. New to this generation of Convertible are the offered 3-temperature neck warmers that permit for cozy open-air driving at large speeds and minimal temperatures.
Drivers of the BMW M4 Convertible can look forward to piloting their car from behind a double-spoke M leather steering wheel. The M logo, chrome trim and shade contrast stitching are central components of the cabin’;s racing ambience. The M4 Convertible comes regular with a 6-pace guide gearbox, although the 6-speed M Double Clutch Transmission is obtainable as an option. M-DCT allows the driver to change gears using either the selector lever on the center console or the shift paddles mounted on the steering wheel.
3-piece retractable hardtop. Type and function.
The BMW M4 Convertible delivers excellent each day driving qualities and a dynamic style, with the leading up or down. These seemingly contradictory qualities were presently mixed in the BMW M3 Convertible, the predecessor that set standards for premium mid-dimension convertibles. The hardtop of the BMW M4 Convertible characteristics a variety of design and style enhancements that reduce noise amounts for a much quieter interior ambience. The sound-absorbing headliner also minimizes wind noise by up to 2 dB in comparison to the predecessor model.
When the top is up, the luggage compartment has a volume of 13. cu. ft. (370 liters) – that is .6 cu. ft. (twenty liters) more than offered in the BMW M3 Convertible. All trunk volumes are based mostly on ECE measures. Even bulky objects can be transported with the BMW M4 Convertible. A flat and level storage spot can be utilized when the backrest of the rear bench seat is folded down. The load-via characteristic, which is standard in the US, can make even far more room available: Both a broad opening amongst the rear passenger compartment and the trunk, or a smaller opening, for skis for instance, when 4 people are seated in the motor vehicle. All it requires is the push of a button to transform a dynamic coupe into an stylish, athletic convertible in a mere twenty seconds. The best can also be lowered when the vehicle is travelling at speeds of up to 18 km/h (approx. 11 mph).
The redesigned windblock is standard in the US. The windblock is now smaller, lighter and simpler to use, plus it is a lot more successful than earlier variants. When it is not needed, the windblock can be stored behind the rear seat to save room, which is also a new function. The BMW M4 Convertible also has lots of room in the trunk, even when the retractable hardtop is lowered. The new convertible provides wider accessibility to the luggage compartment, and an electro-hydraulic loading support program raises and positions the folded hardtop in the trunk as essential to guarantee greatest utilization of the 6.8 cu. ft. (220 liters) of storage space accessible.
The loading help feature makes sure that there is usually ample access to the trunk no matter whether the leading is up or down. 2 storage compartments on the proper and left of the main luggage spot are also offered for stowing little things when the retractable top is up.

The optional Head-Up Show comes with additional, M-certain functions this kind of as a gear show, rev counter and Optimum Shift Indicator.
Hall of Fame: Open-prime performance for above a quarter century
The new BMW M4 Convertible builds on 26 many years of tradition. A Convertible has lined up alongside its 2-door Coupe sibling as a firm fixture of the BMW M3 in all 4 generations.
First generation: the racing auto with the soft-best.
The launch of the 1st BMW M3 in 1986 served mainly to satisfy the homologation specifications for what was then the German Touring Auto Championship (DTM). In purchase to get its place on the grid for this prestigious race series, BMW had to come up with a series- created edition of the competitors car and construct 5,000 examples of it for sale inside of a 12 months. The road-spec BMW M3 was developed with the demands of motor sport quite considerably at center stage and there were no ideas initially for an open-prime edition. Nevertheless, soon after all around 2 many years of resistance, BMW sooner or later gave in to important customer demand, and the BMW M3 Convertible was unveiled in 1988. It was primarily based on the 4-seater BMW 3 Series Convertible and powered by a 4-cylinder engine at first producing 193 hp. In 1990, output was enhanced to 215 hp, enabling the open-leading M3 to accelerate to a top velocity of 148 mph – generating it the world’;s quickest 4-seater series-made convertible at the time. The 1st generation BMW M3 Convertible was not supplied in the US.
Second generation: new advances in safety technological innovation.
The powers that be in BMW’;s motor sport department – now rechristened M GmbH – had planned an additional Convertible edition of the second-generation BMW M3 (launched in 1992 globally and in 1994 in the US) from the outset. Primarily based on the second generation 3 Series Convertible, the BMW M3 Convertible was launched in 1994 with a raft of modern security technological innovation on board. For instance, the rollover bars of the normal rollover protection program – positioned behind the rear seat head restraints – would spring up in an instantaneous if the car was in danger of turning in excess of, teaming up with the ultra-rigid windscreen frame to defend the passenger compartment. In the US, the second-generation M3 Convertible was powered initially by a 240-hp 3.-liter inline-6 that was later enlarged to 3.2-liters.
Third generation: shining an even brighter spotlight on the car’;s sporting character.
In spring 2001, nearly precisely a 12 months following the starting gun had been fired on the third generation of the BMW M3, M GmbH unveiled the Convertible variant to join its Coupe stablemate in the line-up. It was identical to the M3 Coupe up to the A-pillar, but a striking beltline gave the open-top model an even broader, a lot more powerful visual appeal. The BMW M3 Convertible for that reason lower a more muscular, broader, a lot more hunkered-down figure than any BMW M3 before it. And it had the bite to back up the bark hallmark M attributes such as a 333 hp high-revving naturally-aspirated engine, superbly tuned M suspension, a variable M differential lock and M large-overall performance brakes enshrined the
BMW M3 Convertible as an elite athlete.
4th generation: giving the sporting character an even sharper edge.
Significantly less than a year on from the debut of the 4th-generation BMW M3 Coupe and the 4- door Sedan that followed a small later on, BMW stirred the fires of anticipation amongst open-air driving lovers with the launch of the BMW M3 Convertible in spring 2008. A 4.-liter 8-cylinder engine making 414 hp – and sustaining close to 85 % of its 295 lb-ft peak torque across a rev range of 6,500 rpm – gave drivers of the drop-best 4-seater an impressive armoury with which to sate their appetite for sporty, dynamic corner-chasing and relaxed cruising alike.
