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.

2016 Mercedes-Benz GLC250 First Drive [w/video]

There's nothing wrong with the Mercedes-Benz GLK other than old age, having first sold here in 2009. But with creased, off-road themed styling, a naturally aspirated V6, and a smallish interior, it's out of step with the company's growing line of sport utility vehicles. Even its name is a harsh-sounding outlier. Enter the 2016 GLC. Mercedes calls this model the second generation of the GLK, but it's closer to a total reboot. The new look follows the smooth design of contemporary Benzes. The spotlight engine is now a spunky turbocharged four cylinder, and yes, the GLC is bigger inside and out. As for the name change, that's part of the latest badge realignment, and the "C" indicates the GLC's position as the crossover counterpart to the C-Class sedan. Now firmly integrated into the Mercedes SUV family, the GLC takes a seat at the table between the entry-level GLA and the larger GLE. The GLC's fresh appearance has all of the tenets of modern Mercedes design. We've come to the Alsace region of France to sample this familiar yet evolved utility vehicle. Driving along route A35, we're immediately struck by the turbo four-cylinder's prowess. It's strong from launches when we mash the gas, returns a subtle but pleasing exhaust note, and it's more than capable of picking off slower moving traffic as we dash through the French countryside. We're driving the European-spec GLC250 model, which has the same 2.0-liter engine Americans will get in the GLC300, though the Euro model has 30 fewer horsepower. The US version will be rated at 241 hp and 273 pound feet of torque, the same output as the C300 sedan. The turbo has big shoes to fill, as it gives up 61 hp to the 302-hp V6 used in the GLK. Mercedes is banking consumers won't miss this raw power, as the GLC's inline-four offers the same amount of torque as the GLK's V6, but much sooner in the rev band. Even in its detuned European state, the I4 demonstrates the kind of urgency that Americans prefer for their grocery-getting people haulers. It's paired with a nine-speed automatic transmission, upgraded from the GLK's seven-speed. There are paddle shifters, though most Americans won't have reason to use them. Sometimes we grab them and lay on the throttle just for fun, and the GLC responds with bursts of speed. Even in its detuned European state, the I4 demonstrates the kind of urgency that Americans prefer for their grocery-getting people haulers.

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.
