The new BMW M4 Convertible

The arrival of the new BMW M4 Convertible (fuel consumption combined: 9.1–8.7 l/100 km [31–32.5 mpg imp]; CO2 emissions combined: 213–203 g/km) sees BMW M GmbH making another alluring addition to its legendary high-performance sports car line-up. The new M4 Convertible replicates the performance figures of the new BMW M3 Sedan (fuel consumption combined: 8.8–8.3 l/100 km [32.1–34.0 mpg imp]; CO2 emissions combined: 204–194 g/km) and the new BMW M4 Coupe (fuel consumption combined: 8.8–8.3 l/100 km [32.1–34.0 mpg imp]; CO2 emissions combined: 204–194 g/km), but emphasises its stylish and distinctive appearance through its individual character and places the fascination of sporty and dynamic open-top driving at centre stage. The new model finds BMW M GmbH drawing inspiration from a long tradition: BMW’s high-performance sports car for track and road is entering its fifth generation in open-top form with this new chapter in its history headed “M4 Convertible”. 

The BMW M4 Convertible shares the elegant lines of its open-top 4 Series siblings. Its design language allows it to skilfully blend a distinctive and graceful silhouette boasting finely balanced proportions when the roof is open with an exceptionally dynamic coupe line, shorn off B-pillars, with the hardtop closed. At the same time, the M4 Convertible’s styling cues – including a signature power dome for the bonnet, eye-catching exterior mirrors in twinstalk style and flared front and rear wheel arches bulging over forged lightalloy wheels with mixed tyres in 18-inch (optional 19-inch) format – all identify it clearly as a member of the BMW M3/M4 model family. 

Powering the BMW M4 Convertible is the newly developed six-cylinder in-line engine with M TwinPower Turbo technology and high-revving character already familiar from the M3 Sedan and M4 Coupe. The power unit generates maximum output of 317 kW/431 hp from its 3.0-litre displacement and serves up peak torque of 550 Newton metres (406 lb-ft) across a wide rev band. The BMW M4 Convertible therefore offers the driver not only exceptionally sporty performance attributes – the sprint from 0 to 100 km/h (62 mph) takes just 4.4 seconds (with the optional seven-speed M Double Clutch Transmission) – but also sufficient reserves of power to cruise along in relaxed but rapid style with the roof down. 

Like the BMW M3 Sedan and BMW M4 Coupe, the BMW M4 Convertible also displays a strict adherence to the intelligent lightweight construction principle. For example, the bonnet and front side panels are made from aluminium, as are many components of the high-performance chassis. Added to which, ultra-lightweight and – thanks to its hugely impressive rigidity – also extremely durable carbon-fibre-reinforced plastic (CFRP) is employed in many areas of the new M4 Convertible. The drive shaft is one example, the use of CFRP allowing it to be constructed as a single-piece unit. This makes for a significant weight saving and a reduction in rotating masses. The CFRP precision strut in the engine compartment, meanwhile, weighs only 1.5 kilograms yet offers rigidity superior to that of a comparable aluminium component. It therefore plays a key part in the car’s excellent steering response and precision. 

The three-section folding metal roof of the BMW M4 Convertible has full interior lining and represents a compelling proposition with its excellent soundproofing and winter-proof construction. The roof opens at the touch of a button in under 20 seconds – while travelling at up to 18 km/h (11 mph), if required. 

Complementing its already extensive standard specification, the new BMW M4 Convertible can also be ordered with a wealth of attractive options to further enhance its aesthetic appeal, dynamic prowess and comfort levels. And for that distinctive personal touch, the exclusive BMW Individual range of equipment offers the prospect of a unique driving experience. Special colours and materials can be fine-tuned to the driver’s wishes.


NYIAS 2014

The New York International Automobile Show became North America's first automotive exhibition in 1900. For over one hundred years it has continued to bring new and innovative ideas to stage. Every year BMW brings out their latest and greatest joy-producing machines. For this year's show the M4 Convertible joined the previously announced X4 Sports Activity Coupe to make their world debut. The 4 Series Gran Coupe, ALPINA B6 xDrive Gran Coupe, updated X3 and Concept X5 eDrive made their North American debuts. The M3 and M4 were displayed in Silverstone II and Black Sapphire Metallic instead of the originally debuted colors of Yas Marina Blue and Austin Yellow and I have to say they look equally as stunning. The 228i arrived with a Track Handling Package which includes M Adaptive Suspension, Michelin Pilot Super Sports, 18-inch light-alloy wheels, Variable Sport Steering and M Sport Brakes. Of course the best looking electric hybrid ever created, the i8 was there in Protonic Blue. The all new nineT Motorcycle was there showing the beautiful work and craftsmanship from the BMW Motorrad division as well.

The NYIAS is open to the public April 18-April 27, 2014 at the Jacob Javits Center in NYC.


John Guild's E93 M3

In the realm of sports cars, the debate between coupe and convertible owners has been going on for decades. Coupe owners argue that they prefer the weight savings and rigidity of a fixed roof, whereas convertible owners accept that added weight in exchange for a heightened driving experience, exercising all of one's senses. While both opinions have their validity, when it comes to a car as complete as the M3, there is no incorrect choice.

Now that the unofficial start to summer has begun, there's nothing like being lake side at dusk in Bergen County, New Jersey with your supercharged convertible E93 M3 like John's.  As the sun set over the lake, the paint glowed radiantly in the golden light really highlighting the pearl flake on the enlarged arches and hood bulge.  Despite all of the modifications he has done to the car, his color choice is still one of the first things people discuss when examining the car closely. Rather than going with BMW's quintessential “Alpine White”, John chose “Mineral White”.  It is a low production factory color offered on this current generation chassis in a slightly different shade of white with added metallic pearl.  Where it lacks in the crispness compared to Alpine, Mineral White has an added elegance to the car that you notice when walking around it.

John had a vision in mind of how he wanted his car to look, so he reached out to the guys at AUTOcouture Motoring to bring it to life.  He modified his car in large, but gradual steps; what started off as a drop on Racing Dynamics springs and Vossen CV3 wheels has now led to what you see here. After the wheels and suspension he did the ACM headlight mod, which blacks out the factory housing with upgraded LED angel eyes. A Vorsteiner front lip was installed and an Arkym rear diffuser was placed in the back sitting atop his new Akrapovic EVO exhaust.  In completion of the rear end, John sourced a rare Alpina deck lid spoiler.

He was content for a while, but then the mod bug bit hard. Being around ACM and seeing all of the supercharged cars they put out, John knew that was his next move. Not before long, Thomas Limatola, the shop foreman, was installing an ESS VT2-625 kit with P3 boost gauge on this convertible. With the bolt-ons, ESS tune, and supercharger, of course, John is expected to be making somewhere in the neighborhood of 560 wheel horsepower. With all of that power, it is always a rule of thumb to upgrade the braking system. It wasn't a full 3 weeks after finishing the blower that the guys received a call from John telling them that he had a set of Brembo 380mm on the way to the shop in OEM Lamborghini orange.

With everything on the car being upgraded, he felt it was time to do the same with the wheels. He liked the BBK exposure that the CV3's provided, but wanted a lighter weight wheel to improve the performance of the car. He requested BBS FI's in gloss black and 19 inches in diameter and Sal Benanti was happy to oblige. One day after the brakes were completed, the wheels were delivered and wrapped in 245/295 Michelin Pilot Super Sports.  The suspension remains the same RD setup with perfect fitment in the rear, but KW V3 coilovers are on their way in hopes of sitting the front a little more evenly with the back.

I had the pleasure of driving this car to the location for the photo shoot. The combination of the supercharger, blow off valve and Akra exhaust progressively working in union was an absolute treat with the top down. Justifiably, this car earned the attention of everyone it drove past, at least what I noticed from my peripheral. Its presence was felt and was instantly a conversation piece for each person that was walking by at the lake. The package deal of a rare-colored, 600 horsepower convertible with FI's and metallic orange Brembos is just about all that anyone could ask for on a warm summer night.

Those of you, who are on the side of the coupe owners in preferring a hard top, do yourself a favor and go drive a convertible just for the experience. If you ever find yourself in a position to drive a supercharged convertible M3, then you might just find yourself flat-out converted.
