2015 BMW M4 Convertible Quick Spin [w/video]

Quite a while ago, we ran a story where our editors disclosed their guilty pleasure cars. There, I admitted my love for the ultra-comfortable Acura RLX. But I have another automotive guilty pleasure, and it's the BMW M4 Convertible, and the droptop M3 that came before it, as well. Whether it's an E46, E93, or the new F83 M4 model, I just love the idea of a droptop M car. It kind of goes back to my Lexus RC F review, where I posit that most consumers buy a car like this solely for the image. To the point of this car, if you're opting for a convertible, you're boldly throwing out any pretense that you bought this car for its performance. It's a different and far grander indulgence than something like a droptop Ford Mustang, Chevrolet Camaro, or even a Corvette, and that's especially the case with the new M4, as I found out after a week at the wheel. Driving Notes Anyone that's listened to me on the Autoblog Podcast knows I've been none too kind about the state of BMW's turbocharged M cars. In effect, they're too easy to drive. In older models, the narrow power band meant you needed to always keep an eye on the tach, lest you fall into a weak zone. But because today's turbocharged M engines are so damn torquey, you can simply mash the throttle, regardless of engine speed or gear, and zoom forward. That's mostly the case here, although with a 7,500-rpm redline, the M4 at least maintains the illusion that you have to keep the revs up. Power delivery is fast and immediate, capable of catapulting the M4 towards the horizon at even half throttle. But more than the brutal power delivery, this latest M entertains with a strange but familiar singing voice. It's an almost feral, straight-six howl, particularly high in the rev range. But because of the single-scroll turbochargers and today's sound-tuning sorcery, the noise here is far richer and complex than what you'd get in a naturally aspirated M car, like the old E46. The turbos hiss and spit, and wide-open-throttle upshifts come with a cackling snap from the quad-tipped exhaust. Despite my belief that M cars' manual transmissions are generally pretty lousy these days, the M4's gearbox is far better than what you'll find in an M5. The clutch is more forgiving than in the larger sedan, too. With a broad catchpoint and a linear action, it feels natural and intuitive to work.

BMW M4 Convertible poised for Goodwood unveil

It shouldn't be a shock that BMW is working on a convertible version of the M4. Not only have we caught it testing twice, but this is an automaker that seems willing to build a vehicle for nearly every buyer's needs. Evo claims that the high-performance droptop is going to debut at this year's Goodwood Festival of Speed in England from June 26-29.
Judging from the spy shots we've seen, the M4 Convertible will consist of a retractable hard top like the 4 Series cabrio. Other than the roof, there aren't expected to be many changes from the coupe. The engine will be the same turbocharged, 3.0-liter inline six-cylinder engine, but the added weight of the roof and its mechanism may take a small bite out of performance.
We spoke to BMW USA about the rumor and were told that it has no comment at this time. After the M4 Convertible, Evo claims that BMW is working on a M4 Gran Coupe. How that would be all that different from an M3, isn't exactly clear.

BMW readying competition pack for M5, M6

According to Car and Driver, citing a report in BMW Blog, BMW will be offering performance upgrades - likely called the Competition package - for its M5 and M6 models (including the convertible and Gran Coupe versions of the M6). Both cars will continue to be offered with the normal 560-horsepower, 4.4-liter twin-turbocharged V8 engines, but this new performance pack is expected to add an additional 15 hp to the mix.
No need to worry, however - the upgrades won't simply be limited to a small boost in power. These M5 and M6 models will reportedly get new wheels, black exhaust tips, a more direct steering ratio and reworked suspension geometry which will provide better overall handling. Top speed is said to remain governed at 190 miles per hour, but that these extra improvements will shave one-tenth of a second off the cars' 0-60 times.
No pricing information has been revealed as of this writing, though we imagine it'll likely come at a substantial cost over the current starting prices of the M5 and M6 ($90,200 and $108,350, respectively).
