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.

BMW i3 called 'most revolutionary car' since Ford Model T

The Ultimate Driving Machine, or at least one of them, may also be the Ultimate Engineering Success. Consultant Munro & Associates, which specializes in automotive tear-down analysis, pretty much said as much when taking an under-the-skin look at the BMW i3 plug-in. In short, the firm liked what it saw. Presenting at Detroit's Plastic's in Automotive conference this week, Munro CEO Sandy Munro called BMW's first mast-produced plug-in model the most revolutionary car "since Henry Ford's Model T." The car earned big points for its substantial uses of materials that are both lightweight (key for any plug-in's range) and recyclable. BMW has touted these advantages all along. In late 2013, the German automaker went as far as saying its use of carbon fiber reinforced plastic (CFRP) would reduce customer costs related to both repair and insurance. The i3 went on sale in the US last May and, by the end of the year, moved more than 6,000 units here. It sold almost 17,800 The i3 last November also was named the Green Car of the Year at the Los Angeles Auto Show, beating out models such as the compressed-natural-gas-powered Chevrolet Impala B-Fuel and the Audi A3 TDI diesel. Munro made news earlier this week when it offered a free i3 for anyone who bought the master- or OEM-level version of the report, though the report isn't cheap and that offered disappeared once Munro made his presentation. Check out Munro & Associates' press release below. Munro Discusses Groundbreaking Technology Finds from BMW i3 Teardown at Plastics in Automotive Conference; Offers New BMW i3 for Purchasers of Master-level Report DETROIT, Jan. 14, 2015 /PRNewswire/ -- During today's Plastics in Automotive Conference in Detroit, Sandy Munro, CEO of Munro & Associates, Inc., discussed – for the first time publicly – his consulting firm's findings from its extensive deep-dive teardown, costing and benchmark study of the BMW i3 urban electric car. During his presentation, "Deconstructing the BMW i3: Groundbreaking Technology and the Composite Car," Munro discussed the carbon fiber life module, polymer components, recyclability and safety of what he considers to be "the most revolutionary car in terms of creative engineering and manufacturing since Henry Ford's Model T." During the presentation, Munro focused on four crucial aspects of the BMW i3: the manufacturing of its carbon fiber life module; its polymer components; recyclability; and safety.

X1, 3 Series power BMW back into global luxury autos sales lead

BMW managed to eke ahead of Audi for the global luxury sales crown in February. According to Bloomberg, BMW saw deliveries swell by 7 percent in February, besting the 3.2 percent jump enjoyed by Audi and giving BMW a 407-unit delivery lead over its rival last month. Mercedes-Benz, meanwhile, continued to falter, with the brand selling some 37,229 fewer machines than BMW, whose factories are running at full capacity to keep up with demand. Models like the X1 (shown above) enjoyed a sales increase of 40 percent in February while the company's bread-and-butter 3 Series jumped by 26 percent.
Mercedes-Benz hopes to stem its continued market share loss with the addition of the entry-level CLA sedan to its portfolio in April. The company is set to roll out an updated version of its cash-cow E-Class at the same time, and a new-generation S-Class will follow along shortly thereafter. Meanwhile, the company is increasing production to meet demand for its A and B-Class models.
