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.

Alpina B4 coupe will be your subtle M4

We're big fans of Alpina here at Autoblog - the BMW tuner has created some seriously delicious products in the past, and recently tuned the diesel-powered 3 Series wagon to create the D3 Bi-Turbo. What we like most about Alpina is how the cars only look subtly more aggressive than stock, yet they pack a real wallop under the hood.
Take this B4 Coupe, recently spotted testing at the Nürburgring. It looks pretty tame compared to the normal 435i, the only visual additions being the Alpina-standard 21-spoke wheels, modified front lip and rear wing spoiler. But under the hood, Alpina is reportedly working on a tuned, twin-turbo straight-six that produces something like 410 horsepower. That means the B4 should be good for a 0-62 time of 4.2 seconds, with a top speed around 190 mph. Rear-wheel drive will be standard, though our spies suggest that Alpina could also use all-wheel drive here in the B4.
We have no doubt that the next BMW M4 will be super hot, but for those seeking a bit more stealth and exclusivity, this Alpina B4 certainly looks the business. Check it out in our gallery above.

BMW X4 order guide sneaks onto the web

Much like we gave you an early look at the ordering guide for the BMW M3 and M4 (you can now configure those two, as well), yet another list of BMW options has leaked out. This time, the upcoming X4 is the target. We told you last month that prices for the X3-sized, X6-shaped vehicle started at $45,625, and now, we can confirm everything else for the newest Bimmer.
Only two trim lines will be available when the X4 arrives - M Sport and xLine. The former starts at $2,300 for the xDrive28i model and $1,900 for the xDrive35i, and includes as standard, 19-inch wheels (or optional 20s for $950), sport seats, an M steering wheel, a more aggressive body kit, a black headliner and the option of brushed aluminum interior trim. The xLine is $1,500 for the 28i and $1,000 for the 35i, and is made up exclusively of 19-inch Y-spoke wheels and dark copper interior trim.
Metallic colors dominate the pallet, with just a pair of gloss options available alongside the $550 metal-flake colors. BMW offers a pair of SensaTec leatherette options, along side a wide variety of $1,450 leather trims.
