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.

Two rare Alpina BMWs given the Petrolicious treatment

Alpina is getting more and more ink because of because of that rolling cannonade known as the B7 and its closer ties with BMW. The company's tuning business dates to 1962 when Burkard Bovensiepen began fiddling with Weber carburetors, then his company began racing in 1968 and was eventually certified as an automaker in 1983.
Two of its rarer specimens from those early years have gotten a glance from the folks at Petrolicious: the E24 B10 and E24 B7S. Based on the BMW 6 Series, the Alpina versions made one of the most special coupes from the Eighties even more so. According to the video, there were only 44 B10s made, and the turbocharged, 333-horsepower B7S - this was in a luxury coupe in 1982, mind you - saw only 33 examples produced.
You won't be sorry to find out more about them - and see how they run - in the Petrolicious video below.

2014 BMW 4 Series

Because Four Is Greater Than Three
Say what you will about the name 4 Series, there is a method to BMW's madness. On one hand, it's easy enough to just buy into the logic that odd numbers are reserved for sedans and wagons, and that even numbers are reserved for coupes and convertibles. On the other hand, consider the idea that the higher numbers are used to separate the more dynamic, more engaging vehicles that use the same platform. It's that sort of separation that differentiates the 6 Series so nicely from its 5 Series roots, after all. And if we're being cynical, it also allows BMW to charge a bit more money for its lower-volume offerings.
So with the new two-door version of the 3 Series, BMW has gone the route of strengthening the dynamic virtues of its F30 chassis to create a car that's more removed from its sedan kin than one might think. And after spending some time with the new 4 Series on the roads around Lisbon, Portugal, as well as the famous Circuito do Estoril racetrack, it's increasingly clear that calling this car a 3 Series Coupe simply wouldn't be fair.
