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 unveils GLC350e 4Matic PHEV

Mercedes-Benz intends to introduce at least 10 plug-in hybrid models to the market by 2017, and the the Mercedes GLC350e 4Matic is the latest one to show its electrified face. It's also the second crossover from the company to offer a PHEV version following the GLE550e 4Matic. Mercedes isn't releasing all of the details about the plug-in GLC yet, but it combines an internal combustion engine making 208 horsepower and a 114 hp electric motor with a seven-speed gearbox. Total torque is 413 pound-feet. The combo is enough to get the all-wheel drive crossover to 62 miles per hour in a purported 5.9 seconds and a claimed top speed of 146 mph. Fuel economy in the European cycle is estimated at the equivalent of about 90 miles per gallon, and there's a 21-mile pure electric range for zero-emissions cruising. Based around the newly introduced GLC-Class, buyers can still order a plethora of luxurious amenities, but the plug-in powertrain also comes with a few tweaks to help drivers maximize fuel economy. There's a haptic accelerator with a resistance point to indicate the switch between electric and combustion power. In addition, the hybrid system can anticipate the road ahead through radar and GPS to manage things as efficiently as possible. One of the GLC hybrid's biggest advantages when it arrives is the small field of competitors. Neither BMW nor Audi currently have a compact luxury crossover of this size with a hybrid option in the US. That really only leaves the Mercedes to take on the Lexus NX300h with total system output of 194 hp, and that's not even a plug-in. The GLC350e 4Matic isn't part of the new model's initial launch lineup in the US. It should be coming along later, though. Key topic: Energy efficiency - Economy on four wheels A revised all-wheel-drive powertrain, the outstanding aerodynamics and the intelligent lightweight design are the primary reasons for the high energy efficiency of all the new GLC models. The conventional diesel and petrol models boast significant reductions of up to 19 percent in both fuel consumption and CO2 emissions in comparison to the previous generation, while at the same time improving performance.

Lewis Hamilton accepts Vettel's apology, has 'utmost respect'

SPIELBERG, Austria - Triple world champion Lewis Hamilton said he still had "the utmost respect" for Formula One title rival Sebastian Vettel after accepting a public apology from the Ferrari driver on Thursday. Speaking to reporters at a crowded Austrian Grand Prix news conference, the two men addressed a "road rage" controversy that has dominated the headlines since the June 25 race in Azerbaijan. "I still have the utmost respect for him as a driver and will continue to race him hard through the rest of the season," declared Hamilton, who said at the time that Vettel had "disgraced himself" by driving into him in Baku. He said Vettel called him on the Monday after the race and then texted an apology, which he accepted. The championship leader had driven into the back of Hamilton's Mercedes while both were following the safety car in first and second places, waiting for it to return to the pits. Vettel then pulled alongside, gesticulating angrily, before banging wheels. The German, a four times world champion, later accused Hamilton of "brake-testing" him by slowing suddenly. The car's telemetry subsequently showed that was not the case and Hamilton said the accusation was one he particularly wanted correcting. Vettel was handed a 10-second stop-and-go penalty, and finished fourth. He was then summoned to a hearing in Paris last Monday where the governing body declared the matter closed. Initially reluctant to dwell on the matter, saying he did not want to "pump this up more than it is already", the Ferrari driver on Thursday repeated the written apology. "It was the wrong move to drive alongside him and hit his tyres," he said. "I don't think there was any bad intention (by Hamilton). I don't think he actually brake-tested me. I was upset and over-reacted. I am not proud of the moment." Hamilton, 14 points behind Vettel after eight races, missed out on victory in Baku after a headrest worked loose and he had to pit. He finished fifth. Before Baku, the two world champions had made much of their mutual respect and the budding "bromance" seemed to be back on. "It's nice to hear that we are able to move forward," Vettel said. "I think the respect we have for each other on and off track helps us in this regard." Reporting by Alan Baldwin Related Video:
