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 rethinks all-wheel-drive M cars

BMW M hasn't been able to decide whether it wants to jump on the all-wheel-drive bandwagon or not (with the exceptions of the X5 M and the X6 M, which are based on AWD architecture). That might be changing though, since M's president Friedrich Nitschke recently realized that 70 to 80 percent of Mercedes-Benz E63 AMGs are ordered with all-wheel drive. Earlier this year, Nitschke said that there were no new AWD M models planned, so this comes as somewhat of a surprise.
"On our cars we are thinking of all-wheel drive, but it won't come before we get the successor of the M5 and M6," Nitschke said in a Motoring report. "That's the timing and it's not practical to react in the current life cycles."

Rinspeed issues its Budii call for Geneva [w/video]

Of all the concepts prepared every year for the Geneva Motor Show, those made by Rinspeed are typically the most outlandish and forward-thinking. And this is the latest from Frank Rinderknecht and company. Though Rinspeed's been known to build entirely original vehicles from the ground up, it tends to base its creations on production models: Following the Tesla-based XchangE from last year, the Smart-based Dock+Go of 2012, the Fiat-based E2 from 2009 and the Lotus-based sQuba in 2007, the new Budii concept is based on the BMW i3. That means, of course, that it's powered by electricity, but the technology demonstrator is focused more on autonomous driving tech. The Budii incorporates a periscopic camera and laser scanner to map the terrain and the road ahead from above, and a drive-by-wire steering system that allows the steering wheel on an articulated column to be passed between driver and passenger or tucked out of the way to let the electronics take over. Once unburdened of the task of driving, the occupants can enjoy the proliferation of touchscreens, the "wellness shower" (whatever that is) installed in the headliner, the automatic watch-winder on the steering column and the interior accoutrements furnished by Mansory. The whole thing rides on a lowered suspension with 19-inch Borbet alloys, with a rainbow Knight Rider-style grille in the nose. But to appreciate the full scope of the consortium of suppliers that collaborated with Rinspeed to bring the Budii to life, you'll want to delve into the press release after the video below and scope out the dozens of high-resolution images in the slideshow above. 2015 Geneva Motor Show: Rinspeed "Budii" redefines human-machine interaction Reach out to robots The vision of autonomous driving will soon become reality and will fundamentally change the interaction of man and automobiles. While the research centers of the automotive industry are still feverishly working on the technical solutions, progressive thinkers such as the Swiss idea factory Rinspeed are already giving concrete thought to how automated private transport will transform the car and the man-machine system. Besides fundamental conceptual changes, this will also have to involve issues of ethics and society. In the past, the robots in the factories of this world merely assembled cars for people.
