M-fographic breaks down the history of BMW performance machinery

Few characters carry the kind of clout among performance enthusiasts as the letter M. For 35 years now, that one letter has adorned over 300,000 BMWs, each tuned to deliver a higher degree of performance than the stock models on which they're based.
The M division has worked up nearly 100 different models over the past third of a century, which can leave even the most expert among Bimmer fanatics bewildered. Fortunately British auto loan service Carfinance247 has commissioned this handy infographic to make sense of it all, and you can check it out below to see what the letter M really stands for.

2015 BMW M4 Coupe

Launched out of the seat by a huge, unexpected dip in the road, yet still held largely in place by the smooth webbing of my safety belt, I clench my teeth waiting to come back to earth. A tenth of a second later, the M4 Coupe touches down and my body is slammed into the leather seat cushion. All of the air is forced out of my lungs upon landing, but the BMW's chassis, suspension and steering appear unfazed. Pleasantly surprised, I mash the accelerator to the floor in giddy pursuit of the car in front of me - an absolutely identical 2015 BMW M4 coupe.
A cavorting game of cat-and-mouse on a desolate twisty canyon in southern Portugal is an excellent way to explore the real-world driving dynamics and performance of BMW's all-new M4 Coupe. But to truly push it to the limit - without having to worry about oversize depressions in the asphalt - requires a dedicated racetrack. Graciously, my hosts have rented the famed Autódromo Internacional do Algarve racetrack, or Portimão circuit, for an afternoon of automotive debauchery.
It's hard to believe this passes for work.

BMW 6 Series Convertible gets a little work done for 2015

Truth be told, I've never really found the modern BMW 6 Series to be a particularly attractive car, in Coupe, Convertible, or sedan Gran Coupe forms. This current generation certainly looks a whole lot better than the Bangle-fied Six that came before it to my eyes, but on the whole, I find much of the car's design to be fussy and awkward. There's a new 6 Series on the way, scheduled to arrive sometime in 2017 or 2018, but to hold us over until then, BMW is freshening its current range, as evidenced by this convertible prototype our trusty spies recently caught testing.
Will the changes to the current 6 Series be an improvement? Perhaps. Up front, there are restyled headlamps and a new front bumper, and at the rear, BMW has redesigned the LED taillamps to bring them more in line with the rest of the company's offerings. Aside from those modest tweaks, we don't expect much more to change on the Big Six - the interior will likely carry over with some minor tweaks (or new colors), and it's possible the powertrains could be massaged gently for gains in either power, efficiency, or both.
Whether you think this new look is pretty or not, this freshened 6 Series will likely debut sometime next year, while BMW's engineers and designers craft the all-new version. See it from several angles in our gallery, above.
