BMW spied testing new Alpina B7

Just last month BMW released the 2016 7 Series, ushering in a new era for the Bavarian automaker's flagship luxury sedan. And fans of big European performance sedans know what that means: Yes, a V12 model to follow, and maybe an M Performance variant at some point in the future. But before that, we're getting a new Alpina B7. Spied leaving BMW's test center at the Nurburgring, this camouflaged prototype for the new B7 appears to be wearing Alpina's signature low-key visual enhancements. Those include a subtle aero kit and upgraded rolling stock. Though we're only looking at it from the outside, you can expect the interior to feature some similarly discreet upgrades as well. The bigger question is what Alpina will have done to the new 7 underneath the bodywork. The outgoing B7 packed a 4.4-liter twin-turbo V8 with 540 horsepower and nearly as much torque, netting a 0-60 time quoted at 4.3 seconds and an autobahn-crunching top speed of 194 miles per hour. Hardly a slouch, then, but the new Alpina B7 is tipped to pack 600 horsepower or more, which ought to give the high-powered, high-speed, and high-end likes of the Mercedes-AMG S63, Audi S8, Maserati Quattroporte, and Jaguar XJR a run for their considerable money. We smell a battle heating up amidst all that burning rubber and sumptuous leather.

Next BMW 4 Series convertible may ditch folding hardtop

In 2007 the E93 BMW 3 Series convertible switched from a fabric roof to a folding hardtop, but reports out of Germany and BMW say that the next-generation 4 Series convertible will go back to a fabric roof. AutoBild disclosed that nugget last month, now BMW Blog says a BMW source told their sister German publication BimmerToday that it's official and "a decision has already been made." The official car of pro tennis clubs around the world, the droptop 4 Series isn't due in dealers until 2020 or 2021 so one would think there remains some leeway about the top. However, teams of designers are working on the new car right now, so it's entirely possible that a design course is fixed. From the time that the model made the switch, fabric roofs have got so good that there is barely, if any, penalty for using them. It's supposed the change is being made to save weight and free up space. The next 4 Series range is aiming for a lot more sportiness, so on top of its CLAR (cluster architecture) body, it's expected to get active steering, adjustable dampers and anti-roll bars, bigger brakes, and brake-based torque vectoring. Detail improvements like reduced-friction wheel bearings, and faster torque transfer for its all-wheel-drive system are on the long list of upgrades. So too are aluminum and carbon fiber wheels, which will likely be developments based on the carbon wheels BMW showed off last year. Driver assistance options will be legion, with remote-controlled parking, semi-autonomous driving up to 40 mph, and hands-free overtaking perhaps among them.

BMW broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.
Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.
The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.
