2017 BMW Alpina B7 xDrive is an M7 by any other name

Have you been waiting for BMW to release a more potent version of the new 7 Series? Try 600 horsepower on for size and forget all about the famous M badge. The new flagship performance sedan from Munich is the 2017 BMW Alpina B7 xDrive. Alpina is Bimmer's tuner of choice, and it designs customized features to integrate precisely with the factory build. The B7's 4.4-liter twin-turbocharged V8 is massaged to deliver a nice, round 600 horsepower, and a torque figure nearly as impressive at 590 pound-feet available from just 3,000 rpm. All that muscle is channeled through an eight-speed automatic to all four wheels (as you might have guessed from the new xDrive handle). The result is an Autobahn-blitzing 0-60 time quoted at just 3.6 seconds – 0.8 seconds quicker than its predecessor – and a top speed estimated at 193 miles per hour. Those would have been considered supercar figures not that long ago, but are delivered here in a luxury sedan as big as they come. They also stand up pretty well to the forced-induction eight-cylinder competition in the Audi S8 Plus, Jaguar XJR, Maserati Quattroporte GTS, and Mercedes-AMG S63. The Audi produces a bit more power but less torque, the Mercedes does the opposite, and the Jaguar and Maserati are left in the dust. Only the S8 Plus dares claim a quicker 0-60 time, and even then it's only said to be a tenth quicker. (The Mercedes-AMG S65 boasts much higher output from its V12, but without an all-wheel drive system capable of handling all its muscle, it's a fair bit slower off the line.) Keeping all that momentum under control is an air suspension with adaptive dampers, active roll bars, and four-wheel steering. It's all mounted to 20-inch wheels wearing Michelin Pilot Super Sport rubber and packing oversized brakes measuring 15.5 inches at the front (with four-piston fixed calipers) and 14.5 inches (with floating calipers) at the back. Of course it also benefits from all the advancements that the Bavarian automaker developed for the latest 7 Series, but takes things a step further with a specific aero kit and an interior decked out in even more upscale leather and trim. The finished product may not wear an M7 badge as so many have called for from BMW's flagship sedan series over the years. But the Alpina name carries a cachet all its own and has for the past 50 years now – which is a few years longer than BMW M GmbH has been around.

Top Gear drag races the BMW i8 and M4 to decide the future

The BMW M4 and i8 represent two every different expressions of the performance car. The M4 relies on its turbocharged six-cylinder combustion engine to spin the rear wheels. Conversely, the i8 packs a turbo three-cylinder and electric motors for its cutting-edge all-wheel drive system. Top Gear is the latest publication to put the pair together to find out which ethos is quicker. We saw Germany's Auto Bild hold a similar race last year, and the i8 scored a clear victory there. We don't want to spoil the winner of Top Gear's attempt, but we can tease that this sprint ends in a photo finish. Pick your favorite, and then watch the video to see which performance coupe takes the checkered flag. Related Video:

Why are all US-bound BMW i3 EVs with range extenders stuck at port?

The first BMW i3 EVs have been delivered in the US, but in a quirk of the rules, none of them have been the range-extended versions. Long-time BMW electric vehicle driver Tom Moloughney discovered this fact the hard way. His i3 REx has been sitting at a New Jersey port for over a week and he's getting impatient. The problem is something Moloughney calls a "Monroney Hold." So, instead of sitting there fuming, Moloughney did a bit of research and discovered that the problem is something he calls a "Monroney Hold." He says that "the EPA certification has not been completed so BMW doesn't have a Monroney label (window sticker) to post in the window before the car leaves the port, which is required by law. The range extender option changes (shortens) the car's electric range, and also requires an official MPG rating so BMW couldn't use the same Monroney label as they did for the all electric i3." You can read more on his website, but it turns out that the story isn't so simple. For one thing, the EPA testing has been finished. Washington State representative Chad Magendaz told Moloughney that he asked the EPA for an official statement and got the following from Linc Wehrly, Director of the Light-Duty Vehicle Center Compliance Division: "EPA tested the i3 REx and provided the results of that testing to BMW on May 13th. EPA is not aware of anything that would prevent BMW from importing the vehicles since May 13th." Then there's the official word from BMW. Spokesman Dave Buchko told AutoblogGreen that: We are moving as quickly as possible to release the first BMW i3 Range-Extender models to BMW i Centers. Receipt of test data from the EPA is one step, but not the final step, in the process of receiving certification from the EPA. Rules do not permit the release of vehicles for sale until EPA labels are finalized, produced and affixed to any vehicle. Barring any unforeseen delays, we expect that to happen by the end of this week. We have never certified a vehicle like this before. We are taking every precaution to make sure that everything is done in a timely, but more importantly correct manner. In that Monroney labels cannot be produced until the EPA certification process is complete, the characterization [of a "Monroney Hold"] is not technically incorrect, but there is more to it than that, as is often true in life. On a lighter note, BMW donated a loaded i3 to Brad Pitt's Make It Right charity foundation as a fundraiser. Read about that below.
