2014 BMW 4 Series drops its top, priced from $48,750*

BMW will debut its new 2014 4 Series Convertible at the Los Angeles Auto Show in November, and after seeing plenty of spy shots and, most recently, some leaked images, we now have all the official details. To no one's surprise, the 4 Series convertible is, essentially, a topless version of BMW's new-for-2014 4 Series coupe, and will be offered in the United States in the same 428i and 435i guises.
On the base end, that means the 428i Convertible arrives with the company's 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and available with either rear- or all-wheel drive. BMW says the 428i will sprint to 60 miles per hour in a respectable 6.2 seconds. For folks in need of more thrust, BMW will happily sell you a 435i Convertible, available only with rear-wheel drive, powered by a 3.0-liter, twin-turbocharged inline-six that produces 300 hp and 300 lb-ft of twist. Hitting 60 mph in the 435i will take roughly five and a half seconds with the standard eight-speed auto. Curiously, BMW did not mention anything about a six-speed manual transmission for either model, so looks like this droptop might be an auto-only affair. We've contacted BMW for confirmation, so we'll keep you posted.
Like the 3 Series Convertible it replaces, the 4 Series uses a three-piece folding hardtop configuration, and BMW says that added sound deadening reduces audible wind noise by about two decibels. Folding the automatic roof takes just 20 seconds, and can be done at speeds up to roughly 11 mph. For chilly, top-down driving (something we're big fans of), there are now three-temperature neck warmers for the front seats - just like what Mercedes-Benz offers with its AirScarf system.

Is Audi getting complacent and suffering from brain drain?

The argument is made in a Reuters article: Audi is falling behind other luxury brands, such as Mercedes-Benz and BMW, due to a lack of research-and-development spending and "brain drain," or the migration of top executives and R&D chiefs to other parts of the Volkswagen Group. Reuters notes that Audi's current R&D chief is the third in 16 months.
Audi, which contributed to 40 percent of VW Group's $11.6 billion in profit the first nine months of the year, is delivering cars at a record pace: 1.31 million were delivered from January to October 2013 versus BMW's 1.35 million. Yet Audi, Reuters reports, doesn't have a halo car akin to BMW's new electrified i3 and i8 or an answer to Mercedes' plug-in-hybrid S-Class, and the R&D spending at Audi is less than BMW and Mercedes by a fair margin. It's noted in the article, however, that Audi benefits from other R&D spending within VW Group.
Reuters mentions that BMW "trumpets its new 'i' series" and the new Mercedes CLA and GLA ranges are winning "rave reviews" as part of its argument that Audi's recent lack of technological innovation could hurt future sales. Those cars do pack tons of new technology, some of which are firsts for mainstream production cars. But last time we checked, the i3 could be causing BMW's stock to slide, the CLA isn't receiving the rave reviews that Reuters would have you believe and the GLA hasn't been reviewed yet.

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.
