2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

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.

BMW's plans for next plug-in i model, due after 2020

BMW entered the fight in the green car ring with gusto thanks to the one-two punch of the i3 and the i8. However, it seems that there could be a wait ahead before the German's i sub-brand is ready to land another strike at the market. "We are still in the strategic research phase where we brainstorm," Klaus Frohlich, BMW Group development boss, said to Automotive News Europe about the future vehicle. He indicated the next new model to bear the i prefix wouldn't arrive until after 2020. Frohlich also underscored that the sub-brand's products wouldn't be based on a standard BMW product. The German brand was at one point rumored to have a model called either the i5 or i7 on the way that would have added a plug-in hybrid drivetrain to the 5 Series. Frohlich's statement would seem to invalidate that possibility. Although, there's nothing stopping the vehicle from carrying regular BMW branding in the vein of the X5 xDrive40e PHEV. The current i-badged models won't just stagnate on the market in the meantime, though. "We have a minimum 20 percent battery density improvement every three years, thus over the i3 and i8's life cycle, we will offer more performance, more range or a combination of the two," Frohlich said to Automotive News Europe. Sadly, current owners won't be able to upgrade to the improved parts, though. Rumors about a third i sub-brand model go back years with much of the talk swirling around the i5. In addition to the speculation about a 5-Series-based version, there was also supposed to be a stretched variant of the i3 with that name, possibly even with a hydrogen fuel cell version. Although, BMW claimed the vehicle was purely "hypothetical." Related Video:
