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.

Petrolicious shows Mercedes 280SL as architecture in motion

While still an absolute beauty today, the design of the pagoda-roof W113 Mercedes-Benz SL was revolutionary when it debuted. Moving away from the soft curves of the previous SL models, the all-new generation brought an upright, angular shape that was as much architectural as automotive. In the latest video from Petrolicious, owner and architect Daniel Monti expounds on the inspiration that he gets from his 1969 280SL's fantastic styling. The roof is the most famous design feature of this generation of SL. Look at the top from the front or back, and you can see a gentle, downward arc that evokes the look of a pagoda. That one styling element is also a fabulous counterpoint to a vehicle that is largely more angular than curvaceous. Petrolicious wonderfully illustrates how some of the SL's form-follows-function design aesthetic can be found in the architect's work in this video's heaping helping of mid-century modern goodness.

Autoblog's adventures at the Nurburgring 24-Hour race [spoilers]

The brand-new Audi R8 LMS, said to share 50 percent of its components with the street-legal R8 shown off at Geneva, has won its very first race at the 2015 Nurburgring 24-Hours. The No. 28 car driven by Christopher Mies, Edward Sandstrom, Nico Muller, and Laurens Vanthoor for the Audi Sport WRT team out of Belgium finished only 40.279 seconds ahead of the No. 25 BMW Sport Team Marc VDS Z4 GT3 in second place, for the smallest winning gap since the race began in 1970. Those two cars traded the lead throughout Sunday morning and were less than a minute away from one another for the last two hours. They were part of a total 35 lead changes during the entire race – a record for the event – and both did 156 laps. Third place went to the No. 44 Falken Tire Porsche 997 GT3, one lap down. The Audis did what they always do: lurked close to the front, stayed out of trouble, then pounced when everyone else faltered. For the opening stretches the BMW Z4 teams owned it, running 1-2-3 for a while, but all of them hit trouble. When morning came and the race got over its yellow-flag fever, the No. 28 Audi was in front and stayed there. It was the third Nurburgring 24-Hour win for Audi in four years, the brand's first win only coming in 2012. Last year's winner, the Phoenix Audi team that set a race record by doing 159 laps, had both of its cars retire. One hit an oil patch about 12 hours in, spun and was hit by another car behind, taking on too much damage to continue. The other retired with engine issues. Other Notes Three cars crashed out of the race while leading, after the rains that weren't supposed to happen, happened about 90 minutes in. The No. 20 Schubert BMW Z4 led the first 50 minutes of the race, hopped a crest at Pflanzgarten, landed in a pool of water, and hit the wall on the 30th lap. Then the No. 30 Frikadelli Porsche, with a driver team that included ex-'Ring Taxi driver Sabine Schmitz, hit the No. 31 Mercedes SLS AMG GT3 on the approach to Carrousel and crashed out. Then the No. 1 Phoenix Audi, last year's winning car, took the lead but hit the wall after that oil patch near Pflanzgarten and was out of the race. Aston Martin celebrated a class win in the SP8 category with the No. 49 Vantage GT4 N430. This being the tenth anniversary of the Vantage running the Nurburgring-24, this year's car was painted in the same colors as the racecar from ten years ago.
