2016 BMW 7 Series slims down, techs up

BMW is finally pulling the wraps off its sixth-generation 7 Series. The flagship boasts a ton of improvements for 2016, including a smattering of onboard tech and weight reduction of 190 pounds. The 7 Series uses a new internal structure called Carbon Core. Derived from the i sub-brand, Carbon Core uses a mix of carbon-fiber-reinforced plastic and ultra-high-tensile steel for the 7's major structural components. It's largely responsible for the 190-pound weight reduction, along with the aluminum doors and trunk lid. The weight savings has allowed BMW to maintain a fifty-fifty weight distribution. That new structure underpins the largest sedan BMW has ever produced. At 206.6 inches in total, the long-wheelbase-only 7 Series is over an inch longer than its predecessor. Its 124.6-inch wheelbase and 74.9-inch width, though, remain unchanged. Even with such a modest increase in size, BMW is claiming best-in-class rear legroom, at 44.4 inches – a tenth of an inch more than the current 7. Unlike the old car, though, this new 7 Series gets with the times in terms of chauffeur equipment. The front passenger seat can be slid forward and folded, allowing a lucky rear passenger to take advantage of the new pop-out footrest and optional 42.5-degree seat incline, available as part of the Rear Executive Lounge Seating Package. iDrive now adds a number of 3D sensors that respond to pre-programed hand motions. The 7 Series will debut here in the United States with two engines, both of which should be familiar to BMW consumers. There's a 320-horsepower, 3.0-liter, turbocharged six-cylinder in the nose of the 740i, and a 4.4-liter, twin-turbocharged V8 with 445 hp on tap in the 750i xDrive. 60 miles per hour arrives in a relaxed 5.4 seconds for the 740i and 4.3 seconds in the V8 model. Once again, ZF provides the eight-speed automatic transmission used with both engines. Joining the 740i and 750i is the new 740e xDrive. The plug-in-hybrid sedan is motivated by a 2.0-liter, turbocharged four-cylinder and an electric motor, and is capable of 23 miles per charge and speeds of up to 75 miles per hour in pure electric mode. Tthere's no shortage of tech on the latest 7 Series. While we're familiar with some items, like active grille shutters and BMW's Air Breather system, it's items like the gesture-control-equipped iDrive 5.0 that pique our interest. Alongside the new and standard touchscreen, iDrive now adds a number of 3D sensors that respond to pre-programed hand motions.

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.

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.
