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 working on S-Class EV in accelerated green car lineup?

With Mercedes-Benz bringing out coupe and plug-in hybrid versions of its S-Class sedan, the German automaker just may follow through with a battery-electric variant as well. That's what the company's Uwe Ernstberger told the folks at Top Gear during the Geneva Motor Show. And while he noted the company still needs to work in a larger-than-usual battery pack and was less than specific with details, he did envision an all-electric S-Class "in the future." Of course, rumors started bubbling about an EV S-Class as far back as 2011, so we'll see. Christian Bokich, department manager for product and technology communications for Mercedes-Benz USA, would not confirm anything about an electric S-Class, but he did give AutoblogGreen an official rundown of MB's upcoming green cars in the US, starting with the launch of the all-electric B-Class ED in July of this year in the ZEV states (launch details for other states are TBA, he said). An S-Class plug-in hybrid is coming in the first half of 2015, followed by a C-Class PHEV closer towards the end of that year in the USA. There is also a C-Class four-cylinder BlueTEC coming at some point in 2016. Until we get more concrete information about the possible S-Class EV, let's review what we know about the PHEV. Last September, Mercedes-Benz started showing off the plug-in hybrid S-Class, saying that it could go as far as 19 miles on electric power alone and had a preliminary fuel efficiency rating of more than 78 miles per gallon, using the more lenient European driving cycle. Earlier this week, Mercedes showed off its S-Class Coupe. That model's US version will have a twin-turbocharged V8 that kicks in 449 horsepower, a few more than the presumptive S-Class EV will have. Ernstberger also said Mercedes would join the ranks of automakers offering autonomous driving systems and mentioned the S-Class as being at the "top of the movement." He held his tongue when asked about the possibility of an S-Class cabriolet.

Lewis Hamilton wins British GP, slashes Vettel's lead to 1 point

SILVERSTONE, England - Lewis Hamilton won his home British Grand Prix for the fourth year in a row on Sunday, while a penultimate-lap puncture slashed Sebastian Vettel's championship lead to a single point. The Briton's drive from pole to flag on an overcast afternoon was lonely, uneventful and dominant - in complete contrast to his Ferrari rival's afternoon - with Mercedes teammate Valtteri Bottas finishing 14 seconds behind to secure the one-two. "The support has been incredible this weekend. I am so proud I could do this for you all," said Hamilton, who threw himself into the fans for some crowd surfing after the podium celebrations. "The team were faultless this weekend, Valtteri did an incredible job as well, so it's the perfect weekend for us." Far behind in his wake, as Hamilton cruised to a 57th career win and soaked up the applause from an army of flag-waving fans, came sudden drama. Vettel, who had battled on worn tires but looked like securing the final podium position until the blowout, finished seventh after an emergency pit stop with a shower of sparks from the wheel rim. "There was no sign of that happening," said Vettel over the team radio. "There were vibrations but I had it for 20 laps and it didn't get massively worse. The tires didn't look great but they never look great." The German's Finnish teammate Kimi Raikkonen, who had been second before also being hit with a late puncture that sent Bottas and Vettel ahead of him, took third. At the halfway stage of the 20-race season, Vettel has 177 points to Hamilton's 176 with Bottas on 154. Hungary, a circuit where the Briton has won five times before, is next up. Hamilton became only the third driver, after his late compatriot Jim Clark and Frenchman Alain Prost, to win the British Grand Prix five times and the first to take four successive victories at Silverstone. Clark won four in a row in the 1960s, but one was at Aintree and another at Brands Hatch. Red Bull's Max Verstappen finished fourth, ending a run of retirements, with Australian teammate Daniel Ricciardo fifth after fighting through the field. Germany's Nico Hulkenberg was sixth for Renault and Force India pairing Esteban Ocon and Sergio Perez were eighth and ninth with Brazilian Felipe Massa securing the final point for Williams. Jolyon Palmer's miserable run continued, with Britain's only other driver on the grid failing to make the start after his Renault broke down on the formation lap with a brake failure.
