2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

Popular Mechanics Breakthrough Awards honors GM Super Cruise, BMW i3

Our friends at Popular Mechanics have announced the winners of their 2013 Breakthrough Awards, which honor innovations and new technologies in a variety of fields, ranging from medicine to electronics to space travel. Among the winners were a pair of automakers.
The BMW i3 was named one of PM's product breakthroughs, and while the diminutive city car has a range comparable to other electrics, Popular Mechanics was impressed the i3's use of carbon-fiber-reinforced plastic, which allows the i3 to tip the scales at just 2,800 pounds. But the i3's space-age materials wouldn't have been such a smash if it were priced beyond what the general public could afford. BMW's ability to offer a vehicle with such an advanced construction for around $42,000 (nearly half the price of the Cadillac ELR and only about $7,000 more than a Chevrolet Volt or Ford Focus Electric) is wildly impressive and speaks volumes about the future of ultra-light composites in the auto industry.
The other big winner comes from General Motors, which was named an Innovator this year for its semi-autonomous Super Cruise technology that's currently being tested on a Cadillac SRX. The technology, which we've reported on before, combines adaptive cruise control and lane centering into a super system that will allow hands-free driving under certain conditions.

BMW 8 Series turns 25 [w/video]

From the very beginning, the BMW 8 Series was a head turner. It was hardly a common sight in the first place, and the angular lines and low, pointed nose made the GT look like something special on the road. It's been 25 years since the Bavarian brand's flagship coupe of the '90s debuted, and owners celebrated the anniversary in style in Germany.
The 8 Series still looks great today, but its popup headlights give away its age a little. You just don't see them anymore. It was introduced at the 1989 Frankfurt Motor Show as the 850i with a 5.0-liter V12 under the hood capable of 295 horsepower and 332 pound-feet of torque. Later, even bigger V12s would find their way in there. Production lasted until 1999, but they were rather exclusive with 30,621 built in its lifetime.
To celebrate the anniversary, several BMW clubs organized 120 examples for display at the company's headquarters in Munich. The brand took advantage of the display to show off the ultimate 8 prototype as well. The one-off special packed a 550-horsepower V12 and a body with optimized aero. That engine eventually became the basis for the one in the McLaren F1.
