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-AMG previews new C63 Coupe ahead of August 19 reveal

Mercedes has been spending the month of July preparing us all of the debut of the new AMG-fettled C-Class coupe. It dropped an enigmatic teaser video on us at the beginning of the month, followed by a handful of teaser images, and another video after that. Now it's released another batch of images to give us a taste of what to expect. These prototype pictured is still heavily camouflaged, so there's little more to tell from them than we already saw from the spy shots we brought you back in April. We can see the front end a bit better, bearing what looks like the same lower air dam as the C63 sedan, but everything save for the front part of the greenhouse is covered up in the swirly stuff. While the photos posted on the Mercedes-Benz Facebook page refer to this as the C63 Coupe, the AMG post references the Mercedes-AMG C-Class Coupe. Either way, we're expecting it to pack the same 4.0-liter twin-turbo V8 as the sedan (as well as the AMG GT), likely to be made available once again in 469- and 503-horsepower states of tune. Affalterbach has also posted a countdown timer on its website, with 23 days left to go until the new muscle coupe makes its debut. So mark your calendars for August 19, and watch this space for more as the German automaker is sure to keep trickling out more photos, videos, and information between now and then. Related Video:

'The best Lewis' Hamilton faces resurgent Ferrari in F1

SHANGHAI (Reuters) - Lewis Hamilton has raised his game but whether the Mercedes driver can deny Ferrari a second successive win of the season in China this weekend remains to be seen. On paper, the triple world champion is still the man to beat -- the most successful driver by far in Shanghai with four wins to date. "Lewis is the best Lewis that I've seen in the last four years, both on and off the track," said Mercedes team boss Toto Wolff after the Briton started on pole and finished second to Ferrari's Sebastian Vettel in the Australian season-opener. "He has become a pillar of this team and he proved that in Melbourne." But Vettel is leading the championship, the first time a non-Mercedes driver has done that since he took his fourth title with Red Bull in 2013, and once-dominant Mercedes have a fight on their hands. Mercedes, who have taken both the drivers and constructors' titles for the last three years, have won four of the last five races in China. As Melbourne showed, however, past form may count for little in a season of sweeping rule change. "If you think you are going to cruise to victory in the future, based on a track record of success, you'll be proven wrong very quickly," said Wolff. "Australia was a weekend full of lessons, now we go to China ready and excited for another battle." Ferrari have not started a season with consecutive wins since 2004 at the peak of the Michael Schumacher era, the Italian team taking 15 victories from 18 races that season. Vettel's win in Australia ended a victory drought for Ferrari stretching back to September 2015, and drew rare praise from company chairman Sergio Marchionne, but they must now prove they can be genuine contenders. "You really have to go step by step," said Vettel. "It's good to know that we have a great car but it's just the beginning: new regulations, new generations of cars so there will be a lot of progress." The cars this year are longer and wider, sporting fatter tires and more swept-back bodywork as part of a rules shake-up aimed at making them faster, more spectacular to watch and harder to drive. But overtaking has also become more difficult, with Australia raising concern about the lack of real moves. The long straights and wide sweeps of the Shanghai circuit saw 128 passes last year, more than at any other track, and should provide a more definitive verdict.
