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.

Ferrari, BMW lend expertise to Olympic bobsled, skeleton, luge

LONDON — There are plenty of reasons why the sport of bobsleigh is sometimes referred to as Formula One on ice, but few as obvious as Italy's World Cup sleds. Resplendent in Ferrari red, and with a set of team sponsor Pirelli's P-Zero tyres painted on the sides, they are even liveried to look like racing cars. Ferrari, Formula One's most glamorous and successful team, have worked with the Italian federation, whose sleds run without sponsor branding at the Olympics, since 2010 and in the run-up to next month's Pyeongchang Winter Games. Former rival BMW, title sponsor of the World Cup, has long partnered the U.S. bobsleigh team, while McLaren teamed up with Britain's bob and skeleton athletes for the 2014 Sochi Games in Russia. "There's always the link between the Formula One companies, or any motor company, and skeleton and bobsleigh," says Rachel Blackburn, the engineer who has been involved in Britain's skeleton program since 2006 and who used to work for McLaren. "There's the Ferrari sleds and the BMW sleds ... when we were at McLaren it kind of made a good story," she told Reuters by telephone from her home in Dubai. That somewhat manufactured rivalry has died down in the years since Sochi, with McLaren no longer involved and Ferrari's presence low key. But the worlds of grand prix motor racing and sliding sports still have plenty in common. Bobsled, luge and skeleton are among the fastest of Olympic sports, with bobsleds reaching speeds over 90 mph. Drivers are subjected to gut-wrenching G-forces, and crashes can be fatal. And then there is the ongoing debate about cost controls, the direction of future rules, preserving a level playing field and obsessive secrecy — all endlessly recurring themes in Formula One. 80 mph on a tea tray Blackburn said skeleton, where riders hit 80 mph on what has glibly been compared to an oversized tea-tray, sits somewhere between Americas Cup yachts and Formula One cars in terms of speed and aerodynamics. "Applied engineering is far more interesting than the pure stuff, so when its applied to something that's fun and exciting it does make it a lot easier to solve problems," she said. "There is the Americas Cup, sailing, Formula One and the high speed ice sports as well. It's the same concept.

Plug In 2014: BMW i DC Fast Charger is poised to change the EV game

It looks like it's just a blue box on a pole, but BMW's new i DC Fast Charger represents a much bigger deal than just the lowest-cost SAE Combo Charger on the market. BMW sees it as the key to getting more drivers into electric vehicles. As Robert Healey, the EV infrastructure manager for BMW of North America told us, "For [BMW], the future is clear. DC charging really is the future." "DC charging really is the future." – Robert Healey, BMW We spoke with Healey at the Plug-In 2014 conference in San Jose, CA last week about the promise of the new $6,548 DC fast charger. "The strategy is pretty simple," he said. "BMW wants to get as many DC Fast Chargers out there as possible. We're not in the charging business, we're in the EV business and to support the sales of our cars, we have identified some key areas: home charging, public charging and assistant services for EV drivers." That's why the first of the new blue boxes will be installed at the 285 i dealers in the US, many of whom already installed the cables needed for fast charging when they put in the Level 2 chargers, said BMW's Cliff Fietzek, manager of connected eMobility. Even if you haven't gotten a site ready for a DC fast charger, the installation costs for BMW's unit are lower because you don't need to pour concrete (for the wall unit) and the SAE Combo connector plug costs "significantly" less than the competing CHAdeMO plug, Fietzek said. One minor drawback to the BMW DC fast charger compared to the more expensive traditional, full-size DC fast chargers is that the 24kW BMW fast charger allows you to charge to 80 percent full in 30 minutes, while the bigger units can do the job in 20. The good news for EV drivers with SAE Combo cars (which, in the US, means the Chevy Spark EV and the VW e-Golf) is that any driver with a Combo plug car and a ChargePoint card will be able to use the BMW stations. In fact, BMW is talking with both GM and VW on where to install SAE Combo stations in the US so that there is minimal duplication of effort. In other places, BMW is working with other automakers, including Nissan, which uses a competing fast charging standard. "In Great Britain, we are installing triple chargers, the CHAdeMO, SAE Combo and the high-power, three-phase AC that can go up to 43 kW to support the Renault [EVs] and others," Fietzek said.
