Next BMW 6 Series, M6 to take aim at Porsche

Since BMW reintroduced the 6 Series line back in 2003, the big two-door has happily sat as the brand's de facto grand tourer. That will allegedly change come 2017, as Car is reporting that Munich will put its coupe on a diet with the so-called G15 generation, allowing the 6 to go after the likes of Porsche. All three of the current 6's body styles will be carried over for 2017, with the base 640i Coupe trimming over 500 pounds of body fat, to around 3,450 pounds. Even the droptop is getting some lipo, dropping from 4,255 to around 3,750 pounds. It's unclear how much the Gran Coupe will be lightened, as it will be the only member of the 6 Series family that's growing in size. BMW will stretch the wheelbase of its fullsize, four-door coupe, which should make it decidedly more sedan like. The weight savings come thanks to a new modular architecture that promises a "more advanced material mix." That means carbon fiber, high-strength steel and aluminum elements, and even some titanium and magnesium bits. Along with xDrive all-wheel drive, Car is promising new six- and eight-cylinder engines, with the 640i's 3.0-liter, turbocharged gas engine producing 347 horsepower while the diesel mill turns out 333. The 4.4-liter V8 of the 650i will deliver 476 ponies, while the range-topping M6's twin-turbo V8 will reach the magical 600-hp figure. Of course, we can expect to hear more about the next 6 in the coming months and years. In the meantime, though, let us know what you think of Car's positing below, in Comments.

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.

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:
