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.

Mercedes-Benz V-ision e Concept ups the plug-in hybrid van game

The various V-Class vehicles from Mercedes-Benz don't get a lot of press around here, but when the German automaker brings something as unusual as the Concept V-ision E (yes, there's a dash in the name) to the Geneva Motor Show, we're happy to make an exception. The standard powertrain V-Class was first unveiled in Geneva last year and it returns in 2015 as a decidedly Daimleresque take on a plug-in hybrid van with a whole heap of cool new technology under the hood. C'mon, you know you want a luxury plug-in hybrid van. Well, if you think you don't want a van like that, listen to the specs and maybe you'll change your mind. It's got an all-electric range of up to 31 miles (if you're going no faster than 50 mile per hour), roughly 78 miles per gallon equivalent (based on the stated fuel economy of 3.0 liters burned per 100 kilometers) and a top speed of 128 mph. That should be plenty to get the basketball team to the tournament on time and in style. The powertrain has a total system output of 333 horsepower thanks to a four-cylinder engine and a 90-kW electric motor. If those numbers sound vaguely familiar, that's because Mercedes said it's "the same advanced drive system" as what's found in the Mercedes-Benz C 350 e, even though some of the performance figures differ. Stylistically, Mercedes has pulled no punches, adding two sun roofs, a real wood floor, nappa leather and executive seats along with something shiny and silver called "designo titanium alubeam" paint. In short, this is an everything-and-the-kitchen-sink approach to PHEV design, and we like it. It's just a concept, though, so don't go asking to buy one just yet. Instead take a better look in the gallery above and dream of going to the auto show prom in a van like this. V-Class concept car with a PLUG-IN HYBRID drive: Mercedes-Benz Concept V-ision e - Higher Performance at Lower CO2 Emissions Stuttgart, Mar 03, 2015 At the Geneva International Motor Show the Concept V-ision e from Mercedes-Benz presents a preview of the great variety of development potential offered by the V-Class. The concept vehicle combines environmentally friendly performance with the lightness of modern luxury. The most advanced PLUG-IN HYBRID technology available ensures extremely powerful propulsion in the model, as the highly efficient drive-system duo consisting of a gasoline engine and an electric motor delivers total system output of 245 kW (333 hp) and system torque of up to 600 Nm.

Brabus spools up new 850 6.0 Biturbo Coupe

With a 5.5-liter twin-turbo V8 cranking out 577 horsepower and 664 pound-feet of torque, the Mercedes-Benz S63 AMG Coupe is not the first vehicle we'd figure was in need of an upgrade. But the folks over at Brabus have evidently felt otherwise, bringing the 850 6.0 Biturbo Coupe to the Geneva Motor Show this year. Now the name might be slightly misleading, but not by much: the revving heart of this beast has been bored out to 5.9 liters and its output raised to 838 horsepower (by our standards). The modified engine also includes new turbochargers, breathing apparati and a remapped ECU to produce an even more prodigious 1,069 pound-feet of torque – although to keep the whole thing from going up in flames, Brabus has limited that last figure to 848 lb-ft. The top speed has been limited to "only" 217 miles per hour to keep the tires from melting, but it'll reach 62 mph from a standstill in just 3.5 seconds. That makes this bahn-stormer blisteringly fast, though the seven-speed automatic transmission and all-wheel drive system have been left largely unchanged. Naturally that's not the end of the story, as the Brabus 850 6.0 Biturbo Coupe also features a full new carbon-fiber aero kit, wheel options ranging from 18 inches to 22, a completely refitted interior and oh, so much more. Chances are you'll never see one sitting still, so you'll want to scope it out in the slideshow of live images from the floor of the Geneva Palexpo for a closer look. Related Video:
