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.

2014 BMW 4 Series Convertible [w/video]

Here it is, the fifth generation of BMW's 3 Series Convertible - only this one begins with a "4," having been rechristened as a droptop version of the new 4 Series Coupe. With thirty years of work on this same recipe and having gotten it so right for much of that time, the Munich compact premium convertible has been a WYSIWYG affair for decades: once you saw its sedan paradigm, you knew what it was going to look like in roofless two-door form, and what you saw is exactly what you got.
It is ridiculous to think that BMW would choose this new model and its new nomenclature to muck things up. The new car has, though, gotten larger and roomier, and even though it's now part of the racier coupe division within the company's compact line, it has gotten more, shall we say, mature. Driving even further away from the days when handsomely tipped bartenders could work their way into one, The Ultimate Tanning Machine had shed even more elan, going instead for elegance and an attitude befitting its $49,675 starting price (including $925 for destination).
It strikes a few odd notes, but what it does best, it still does better than anything else out there in its price range.

BMW Concept Roadster has two fewer wheels than we were expecting

The annual Concorso d'Eleganza Villa d'Este on the shores of Lake Como is an opportunity for some of the most beautiful vehicles in the world to descend on one of the poshest places on earth each year. Unsurprisingly, the event is also increasingly the chance for automakers to debut exclusive concepts to some of the wealthiest auto enthusiasts in the world. In the last few years, BMW has become the masters of this annual unveiling with automotive concepts like the Gran Lusso Coupé, BMW Zagato Coupe and motorcycles like the the gorgeous Concept 90, not to mention the just-revealed Mini Superleggera Vision. But this year the Bavarian automaker has been somewhat tricky.
What would you first think when you heard of the BMW Concept Roadster? A lithe, two-seat convertible? Nope. This roadster is a cut-down, minimalist motorcycle with an ultra-modern design. As opposed to the retro looks of the Concept 90, this naked bike looks like it could fit in a BMW showroom tomorrow and not seem out of place.
The Concept Roadster packs the brand's classic two-cylinder boxer engine displacing 1,170 cubic centimeters and producing 123 horsepower and 92 pound-feet of torque. That power is routed to the rear wheel via a cardan drive, essentially a driveshaft, with a single-sided swing arm rear suspension. It's all nestled in a tubular spaceframe.
