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).

2015 BMW Alpina B6 xDrive Gran Coupe

Alpina has been lovingly modifying BMWs for half a century, but as we learned during a tour of the company's HQ in Buchloe, Germany, Alpina has been in the wine distribution business for nearly as long. The company has an estimated million bottles on reserve in two warehouses and a beautiful wine cellar/tasting room on property in western Bavaria, just yards from where its 1,500 hand-crafted automobiles per year are produced.
What does that have to do with the new B6 Gran Coupe? Well, it may help make sense of the overall character of Alpina's automobiles, especially vis-à-vis the similarly priced, similarly powerful M Cars that BMW sells in far greater numbers. Alpinas are built by wine connoisseurs for wine connoisseurs, or wine connoisseur types; they are not rip-snortin' racecars for the road - that's M's domain. Alpinas are esoteric, rich in character and nuanced. But make no mistake: they are very, very fast.
Our brief first drive of the B6 Gran Coupe - the only 6 Series-based Alpina we'll get in the US for 2015 - took place on German autobahns and Austrian alpine roads, where the car is more at home than anywhere in the world, both literally and figuratively. With 540 horsepower and 540 pound-feet of torque on tap from its twin-turbocharged 4.4-liter V8 and xDrive all-wheel drive, the B6 is said to be able to hit 60 miles per hour in 3.7 seconds on its way to a top speed of 198 mph, a massive 43 mph faster than the M6, which is electronically limited to 155 mph. Yet even at insane speeds - we saw an indicated 190 mph on one particularly lonely stretch of Autobahn - the B6 feels more luxurious than sporty, taking the countenance of a low-slung Bentley Continental GT or an Aston Martin Rapide S, not a knife-edged supercar. It doesn't feel scintillating like a Porsche 911 GT2; rather it feels rock steady, like the 4,780-pound luxury sedan it is.

Vorsteiner BMW M4 GTRS4 shows how to do a widebody at SEMA

Part of the joy of the SEMA Show is that all of the best tuners in the world are competing to show off their wares, and the challenge often pushes the companies into some absolutely insane directions. Case in point: Vorsteiner and its ludicrous GTRS4 wide body kit with the BMW M4.
According to Auto Evolution, the kit reportedly adds 4 inches in the front to fit 10.5-inch-wide wheels and a massive 7-inches more in the rear to snug in 13.5-inch-wide wheels, but spinning around the BMW in these images makes the changes look even more extreme. Beyond just the extra room in the fenders, the lower air intakes are ready to suck in huge volumes of cool air, and there's a front splitter to keep things planted. The front and rear extensions are joined by side sills that grow the farther back they go. Finally, at the rear, the M4 gets a reworked diffuser with mesh inserts.
This is just the type of automotive craziness that makes SEMA interesting. Take a lot at it for yourself in the gallery.
