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.

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.

Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.
