BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

BMW 6 Series Convertible gets a little work done for 2015

Truth be told, I've never really found the modern BMW 6 Series to be a particularly attractive car, in Coupe, Convertible, or sedan Gran Coupe forms. This current generation certainly looks a whole lot better than the Bangle-fied Six that came before it to my eyes, but on the whole, I find much of the car's design to be fussy and awkward. There's a new 6 Series on the way, scheduled to arrive sometime in 2017 or 2018, but to hold us over until then, BMW is freshening its current range, as evidenced by this convertible prototype our trusty spies recently caught testing.
Will the changes to the current 6 Series be an improvement? Perhaps. Up front, there are restyled headlamps and a new front bumper, and at the rear, BMW has redesigned the LED taillamps to bring them more in line with the rest of the company's offerings. Aside from those modest tweaks, we don't expect much more to change on the Big Six - the interior will likely carry over with some minor tweaks (or new colors), and it's possible the powertrains could be massaged gently for gains in either power, efficiency, or both.
Whether you think this new look is pretty or not, this freshened 6 Series will likely debut sometime next year, while BMW's engineers and designers craft the all-new version. See it from several angles in our gallery, above.

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.
