2014 BMW M6 Gran Coupe is ready for your favorite roads

We've known about the ins and outs of the lovely BMW M6 Gran Coupe for a while now, but that doesn't mean we weren't happy to see the thing in the metal for the first time, here in Detroit.
The M-tuned Gran Coupe utilizes the same 4.4-liter forced-induction V8 that powers both the BMW M6 and the M5, with an output of 560 horsepower and 500 pound-feet of torque. The fast four-door brings up 60 miles per hour in just 4.1-seconds - the same sprint time as the M6 coupe and a few tenths quicker than the M5 - and up to a limited top speed of 155 mph.
We love those performance figures - this is one new Bimmer that we're amped to get some seat time in - though we're not super crazy about the selection of chrome wheels on this particular show car. Tells us what you think about the hotted up Gran Coupe in comments, below.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

BMW 2 Series Active Tourer corners surprisingly flat on 'Ring

With seven seats and front-wheel drive, you might not expect the upcoming long-wheelbase version of the BMW 2 Series Active Tourer to live up to the Ultimate Driving Machine reputation that BMW has fostered over the years. But the latest spy clip from the Nürburgring suggests otherwise.
The Bavarian automaker has apparently been testing its new people mover on the Nordschleife, getting it ready to join the growing 2 Series family. And though it's wearing heavy camouflage, we can clearly see from the video below that it's cornering impressively flat - which bodes well for those who'll need to transport their expanding family but aren't prepared to give up on handling.
