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.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

Race recap: 2016 Belgian Grand Prix is a dozen angry laps

The calm of the Formula One summer break ended with the tumult of the Belgian Grand Prix. The first two days included unusual tire pressures and grid penalties; Mercedes-AMG Petronas' Lewis Hamilton started 21st because of a 55-place grid penalty for engine and gearbox changes, McLaren's Fernando Alonso started 22nd due to a 60-place penalty for the same offenses. The bedlam rolled right into what was effectively an 11-or 12-lap race. Mercedes driver Nico Rosberg took off from pole and the cameras barely bothered with him until he took the checkered flag 44 laps later. Red Bull's Max Verstappen bogged from second on the grid, got swallowed by Ferrari's Sebastian Vettel and Kimi Raikkonen on the way to Turn 1, then attempted to recover by sticking his Red Bull's nose between Raikkonen's sidepod and the apex at the first corner. Vettel, who didn't see Verstappen, turned into La Source leaving only enough room for Raikkonen. Three cars don't fit in a space for two cars. Vettel spun, Raikkonen and Verstappen clobbered one another and all three drivers had to pit for repairs. Force India's Nico Hulkenberg zig-zagged his way into second ahead of Red Bull's Daniel Ricciardo, Williams' Valtteri Bottas, and Sergio Perez in the second Force India. On Lap 6 Kevin Magnussen lost his Renault at Raidillon at the top of Eau Rouge and flew backward into an enormous crash. Magnussen escaped with just a cut ankle. The Safety Car paraded the field for four laps before officials red flagged the race to repair the barriers. When racing resumed on Lap 10, Rosberg led Ricciardo, Hulkenberg, Alonso, and Hamilton. Ricciardo stayed ahead of Hamilton to keep second place at the end of the race, Hamilton easily got around Alonso and Hulkenberg to lock up third. Hulkenberg – who'd given up second to Ricciardo by pitting during the Safety Car period – earned another career-best fourth position ahead of teammate Perez in fifth, followed by Vettel and Alonso on recovery drives, Bottas, Raikkonen, and Felipe Massa taking 10th in the second Williams. Rosberg reignited his Driver's Championship charge with the victory, closing to nine points of leader Hamilton. We could argue that Hamilton had an equally good day by driving from 21st to third, limiting his loss to only 10 points. About that Verstappen, though... We've seen far more experienced drivers attempt the same move Verstappen made into Turn 1 – Raikkonen on Bottas in Russia in 2015, for instance.
