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.

Recharge Wrap-up: Nissan and Endesa launch V2G project; BMW denies Apple will use i3

Nissan and Endesa will work together to deliver a mass-market vehicle-to-grid (V2G) system. The technology would allow users to charge their vehicle during off-peak hours, and sell energy back to the grid during periods of high demand. The two companies are looking to launch V2G technology in Europe, as well as exploring second-life projects using retired EV batteries for stationary energy storage. V2G allows users to lower the cost of ownership of their EV, and also helps stabilize the grid, particularly in countries that use a large amount of renewable energy. Endesa will demonstrate its V2G technology system in Madrid on March 12. Read more from Nissan. BMW denies reports that Apple will build a car based on the i3. German magazine Auto Motor und Sport said that such a deal was in the works, and that the Apple car could be sold by Apple and serviced by BMW. "We are in regular talks with companies from the IT and telecommunications sector, including Apple, concerning topics like connected vehicles," says BMW. "Developing or building a car is not a topic of these discussions." Anonymous sources say that Apple could have a car available for production in 2020. Read more at Automotive News Europe. BluepointLondon will take over the management of 60 EV charging stations from Transport for London. The 60 chargers are in the boroughs of Southwark and Sutton, and Bluepoint expects to take over management of charging infrastructure in other London boroughs as well. "A better maintained and more extensive charging infrastructure will mean more drivers are able to use electric vehicles and join the early-adopters who are already helping London reach lower emissions level," says BluepointLondon Director Christophe Arnaud. "We are very excited to be playing our part." BluepointLondon aims to manage 6,000 charging points in London by 2018. Read more in the press release below. Efficient Drivetrains, Inc. (EDI) offers plug-in hybrid conversions for GM light-duty trucks. The PHEV drivetrain offers all the performance of the original model, but reduces consumption and emissions by as much as 80 percent. It offers 30 to 40 miles of all-electric range plus enough energy to act as an idle-free power supply for tools and the like without depleting range. The EDI drivetrain can even be used to charge other EVs. Says EDI's Charlie Travis, "The light duty truck class is an important and high-volume vehicle category for fleet owners.
