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.

New BMW i3-like Visio.M EV concept uses lightweight resin

It's not a new version of the BMW i3, but an updated version of a lightweight concept car from SABIC, BMW, the Technical University of Munich, Daimler and others does bear a certain resemblance to the well-designed plug-in city car. From the black "glass" in the hatch to the angled line tail lights to the up-and-down window line, you can see a sort of family resemblance (see an i3 comparison photo here). And, of course, they both have an electric powertrain. But the changes made to the new lightweight urban electric concept vehicle is more of an exercise in what's possible rather than a way to evolve the i3 and i8 into a broader i family of vehicles. Even so, what we see here is interesting, since SABIC found all sorts of new ways to take weight out of the car as part of the Visio.M (Visionary Mobility) project, which was first announced in 2012. Let's start with the window material, which as you might guess from the quotation marks above, is not made of glass but is instead SABIC's Lexan polycarbonate (PC) resin plastic. The lower weight (the PC helps shed about 29 pounds) adds two miles of range while the PC resin has better thermal conductivity compared to glass and so does even more because the HVAC system can be more efficient. According to SABIC's computational fluid dynamics analysis, an extra 9-10 miles of range, in fact. Without the battery, this concept weighs just 992 pounds. Remember, BMW already made a lot of weight-reduction measures in the i3 thanks to carbon fiber reinforced plastic, so to make the "glass" lighter would only help boost efficiencies on a production vehicle that uses a resin like this. Read more below. SABIC's LEXAN™ resin delivers weight savings and thermal efficiency for new ultra-lightweight electric car concept developed by BMW-led Visio.M Consortium Munich, October 20, 2014 Today, at the Technical University of Munich (TUM), BMW, Daimler, TUM scientists and a consortium of industry participants showcased a lightweight urban electric concept vehicle with various advances, including an all-plastic design of the car's windows. The windows are made of LEXAN resin, a polycarbonate (PC) material, and coating technologies from SABIC, a leading developer of PC glazing for automotive windows and many other thermoplastic solutions for the automotive industry.

Watch man destroy his M6 'lemon' with a sledgehammer and ax

Just to be clear, the owner of this BMW M6 isn't ready for another one. He and his friend destroyed the V10-powered coupe in anger at the entrance to the Frankfurt Motor Show in a decidedly public fashion. Bild and GT Spirit report that the owner was angry over mysterious quality and reliability issues that he claims BMW wasn't able to fix. What we have here, folks, is claimed to be a very expensive lemon.
As the story goes, owner Pourmohseni Hadi bought the 2007 M6 in 2008, and five years later, he is still complaining about mysterious vibrations, rattles and severe jolts during gear changes - the latter he says have caused passengers to become nauseous. The car was taken to several BMW repair shops in Italy and Hadi says he he has written a letter to the automaker about his issues, but the car was never fixed and the letter unanswered, he claims. What we don't know is how many miles the car has been driven and when all these problems started happening. The situation reminds us of a certain Lamborghini Gallardo from a couple years back.
While we understand Hadi's frustration, perhaps an M6 just doesn't suit his tastes. After all, we'd be lying if we said a perfectly functioning M6 of this generation wasn't bumpy over uneven surfaces and wouldn't make some passengers nauseous, with its stiffly sprung suspension and dizzying 500-horsepower V10. Anyone wanna bet his M6 was equipped with one of BMW's notoriously abrupt SMG single-clutch gearboxes?
