2014 BMW Z4 offers minor refinements with a majorly orange wrapper

The redesigned BMW Z4 was rolled out onto the show floor at the Detroit Auto Show, with the example in question being an sDrive35is variant, with the just-less-than-screaming Hyper Orange Package. The exclusive colorway includes the metallic orange paintjob, as well as trim-specific seats, stitching and accents for the interior. More importantly, the 35is driveline means that you'll find a high-output version of the turbocharged 3.0-liter N54 engine, here outputting 335 horsepower and 332 pound-feet of torque, and a 7-speed DCT gearbox.
Two slightly less ferociously powered versions of the Z4 will be available for the new model year, too (both familiar). The Z4 sDrive35i is good for 300 hp and 300 lb-ft, while the still-potent sDrive28i features a 2.0-liter turbo four-cylinder making 240 hp and 260 lb-ft.

BMW to finally put i8 Spyder into production

The BMW i8 Spyder might finally see production. The vehicle debuted in concept form over three years ago, but despite the coupe version having long since arrived in showrooms, the convertible has been nowhere to be seen. According to the latest reports from Germany, however, that's about to change. According to Automotive News, the company's new chief executive Harald Krueger told German publication Handelsblatt that we'll soon see the BMW i8 Spyder in production form. The prospect of open-air motoring under prodigious amounts of electric power sounds enticing, however we'll have to wait and see just what sort of roof mechanism the production model incorporates. The concept had removable roof panels, however the manufacturer tends to favor automatic roof setups – hardtops in the Z4 and 4 Series, or soft tops in the 2 Series and 6 Series. Around the same time, BMW could introduce a power upgrade in the form of a larger internal combustion engine and a higher-capacity battery to go with it. A 2.0-liter turbo four is tipped to slot in where the current three-pot sits, bringing output up to a solid 450 hp – and with a longer range to boot. If those upgrades to arrive – with or independent of the open-roof version – expect them to be implemented on the coupe as well as the roadster.

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.
