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.

A weird end to a weird F1 season | 2016 Abu Dhabi Grand Prix recap

The 2016 Formula 1 season ended with a bang that came from a direction no one expected. Lewis Hamilton put his Mercedes-AMG Petronas on pole position and then got away clean to start the race. Teammate Nico Rosberg did the next best thing, lining up in second and following right behind Hamilton for most of the race. Other than Rosberg's wicked pass on Red Bull's Max Verstappen to retake second place on Lap 20, things stayed all quiet at the front. Come Lap 32 of the 55-lap race, however, observers began to wonder why Hamilton was driving so slow. The Brit, working every trick he could think of to win the Driver's World Championship instead of just the race, dogged it out front trying to push Rosberg back into the chasing mix of Red Bulls and Ferraris. Over the next 15 laps Hamilton's race engineer repeatedly radioed ideal lap times. Hamilton only occasionally hit the times until finally saying, "I suggest you let us race." When the one-stopping Sebastian Vettel blasted his Ferrari from sixth to third, nosing up to Rosberg's gearbox, Mercedes team honcho Paddy Lowe got on the radio to instruct Hamilton to go faster. Hamilton replied that if he wasn't going to win the championship he didn't care about winning the race. Hamilton repeatedly zoomed through the first sector to keep everyone behind, then clogged up the works through Sectors 2 and 3. The problem with his plan was that the Red Bulls in fourth and fifth couldn't get close enough to threaten the trio at the front; even if Vettel had got by Rosberg, Rosberg would still win the Championship with a third-place finish. As it happened, Rosberg finished second behind the disconsolate Hamilton. Vettel took third, followed by Red Bull drivers Verstappen and Daniel Ricciardo, then the second Ferrari piloted by Kimi Raikkonen in sixth. Nico Hulkenberg took seventh, beating Force India teammate Sergio Perez for the last time as an intra-team rivalry. Felipe Massa closed his F1 career with ninth place in a Williams chassis that he got to take home as a gift from the team. Fernando Alonso scored the final point for McLaren, a touch of sweet for the team after the bitterness of Jenson Button retiring on Lap 12 with suspension damage. Rosberg's second place earned him 385 points for the season, enough to take the World Driver's Championship from Hamilton by just five points. Some have put the title down to Rosberg's consistency, others to his car's reliability.

Recharge Wrap-up: KillaJoule hits 270 mph; Mercedes B-Class ED gets PlugShare

The Mercedes-Benz B-Class Electric Drive will get its own version of the PlugShare charging-station locator app. Developed by Recargo with the help of Daimler, the vehicle-specific app will be integrated into the car's navigation system. The system maps the location of nearby charging stations from various networks. So far, Mercedes-Benz doesn't offer a universal pay service for the various charging networks, like those offered by BMW and Nissan. Read more at Green Car Reports. HyperSolar uses solar energy to make hydrogen from water. Without using electrolyzers, HyperSolar uses a photochemical process to separate and capture the hydrogen in the water, which can then be used for clean energy, such as automotive fuel cells. The solar devices are submerged in water inside a container, and sunlight powers the device to free the hydrogen. HyperSolar claims that its process is more efficient and cost effective than other methods used to produce hydrogen from water. See some demonstrations in the videos below and learn more at HyperSolar's website. Eva Hakansson drove the KillaJoule electric motorcycle to a top speed of 270.224 miles per hour. After a computer model showed a possibility of about 270 mph, the team took the motorcycle with sidecar out to the salt flats for Mike Cook's Shootout. Everything went smoothly, and Hakansson easily surpassed speeds of the 249.1-mph world record she set a few weeks ago. The team is calling it quits for the season, but will make some tweaks to the KillaJoule in hopes of getting 300 mph out of the red bullet next year.
