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.

The next-generation wearable will be your car

This year's CES has had a heavy emphasis on the class of device known as the "wearable" – think about the Apple Watch, or Fitbit, if that's helpful. These devices usually piggyback off of a smartphone's hardware or some other data connection and utilize various onboard sensors and feedback devices to interact with the wearer. In the case of the Fitbit, it's health tracking through sensors that monitor your pulse and movement; for the Apple Watch and similar devices, it's all that and some more. Manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality. As evidenced by Volvo's newly announced tie-up with the Microsoft Band 2 fitness tracking wearable, car manufacturers are starting to explore how wearable devices will help drivers. The On Call app brings voice commands, spoken into the Band 2, into the mix. It'll allow you to pass an address from your smartphone's agenda right to your Volvo's nav system, or to preheat your car. Eventually, Volvo would like your car to learn things about your routines, and communicate back to you – or even, improvise to help you wake up earlier to avoid that traffic that might make you late. Do you need to buy a device, like the $249 Band 2, and always wear it to have these sorts of interactions with your car? Despite the emphasis on wearables, CES 2016 has also given us a glimmer of a vehicle future that cuts out the wearable middleman entirely. Take Audi's new Fit Driver project. The goal is to reduce driver stress levels, prevent driver fatigue, and provide a relaxing interior environment by adjusting cabin elements like seat massage, climate control, and even the interior lighting. While it focuses on a wearable device to monitor heart rate and skin temperature, the Audi itself will use on-board sensors to examine driving style and breathing rate as well as external conditions – the weather, traffic, that sort of thing. Could the seats measure skin temperature? Could the seatbelt measure heart rate? Seems like Audi might not need the wearable at all – the car's already doing most of the work. Whether there's a device on a driver's wrist or not, manufacturers seem to be developing a consensus that vehicles should be taking on some of a wearable's functionality.

Recharge Wrap-up: Renault e.dams wins Formula E Marrakesh ePrix, S. Korean Tesla store opens this month

Renault e.dams has won the 2016 Formula E Marrakesh ePrix. The win at the season's second round gives the team a strong lead with 74 points. ABT Schaeffler Audi Sport and Mahindra Racing are tied in second place with 36 points. Renault e.dams driver Sebastien Buemi took first place in the race, with teammate Nico Prost finishing fourth. "We know we have an efficient car and we had to take advantage of that after we started further back on the grid than we wanted," says Buemi. "I was able to extract everything I needed from the car and it shows the team is working really well, so it's been a very positive start to the season."

Of the 12 companies providing public charging networks and services, Navigant has named The New Motion, ChargePoint, and EV-Box as "leaders" in the field based on market share, breadth of products, and market adaptability. Following that group of three are a group of "contenders," including Chargemaster, Fortum, Innology SE, Greenlots, Clever A/S, EVgo, POD Point, and SemaConnect. Trailing those is Car Charging Group in the "challengers" category. Read more at Green Car Congress. BMW has entered the second phase of its ChargeForward program to study advanced EV charging. In partnership with Pacific Gas and Electric Company, BMW is inviting i3 and i8 owners in the San Francisco Bay Area to apply to participate in the second phase of the smart charging project, which aims to test technology that optimizes charging for the benefit of the electric grid. "By managing charging when a BMW i or iPerformance vehicle is plugged in – wherever the vehicle is plugged in – BMW can ensure that vehicles are efficiently charged to meet driver's communicated mobility needs while helping the grid reach greater levels of efficiency and sustainability," says BMW's Manager of Connected eMobility, Cliff Fietzek.
