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.

2014 BMW 4 Series Coupe images leak out

Because embargoes were apparently made to be broken, images of the 2014 BMW 4 Series coupe have leaked onto the Internet ahead of the car's official debut thanks to Car Design News' Facebook page. As you'll recall, the 4 Series is the replacement for the outgoing 3 Series coupe, its nomenclature falling in line with the rest of BMW's lineup, where coupes and convertibles will be set apart from their sedan counterparts by one number.
As we can see in the photos, the 4 Series takes a lot of its design cues from the 3 Series on which it is based, but there's a lot more in the way of attractive body sculpting, and this production model stays true to the original 4 Series Coupe Concept that we saw at the Detroit Auto Show earlier this year.
We don't have official details to divulge just yet, but we can discern from the photos that the range-topping coupe will be the 435i model, likely powered by BMW's turbocharged 3.0-liter inline-six from the 335i. There will no doubt be a 428i model with a 2.0-liter turbo-four underhood, and we expect BMW to offer its xDrive all-wheel-drive system on both models. Much like the 3 Series, a variety of trim levels will be on offer, including a top-spec M Sport trim that you can see painted in Estoril Blue here.

These BMW M6 GTLM racing liveries are great

This weekend we'll see a whole new crop of racing machinery line up for the start of the 24 Hours of Daytona, including the new BMW M6 GTLM. So far we've only seen it in flat black, but now the Bavarian automaker has revealed two special liveries for the two cars it will be fielding in the race this weekend. The number 25 car features a throwback livery that reinterprets BMW's classic racing stripes of red, dark blue, and light blue over white bodywork. It's designed to be reminiscent of – and even features images of – legendary racing machinery from the Roundel marque's history. Those include the 3.0 CSL that wore the same number when it took the company's first win in the US at Sebring in 1975, the M1 sports car from the early 1980s, the V12 LMR that scored BMW's only Le Mans victory to date in 1999, and the M3 GT that dominated the American Le Mans Series in 2011. The second car features a more futuristic livery, wearing the number 100 to mark the automaker's centenary and a multicolor lattice design applied with a luminescent 3D-effect reflective vinyl on a white body. They'll both be fielded by BMW Team RLL, a partnership between the manufacturer and Rahal Letterman Lanigan Racing (of Indy fame), which took a class win at Laguna Seca last year. The new M6 GTLM replaces the previous Z4 GTLM and will proliferate across racing grids in motorsport series around the world following its race debut this weekend. But it won't be the only new piece of racing kit turning a wheel in anger for the first time at Daytona; the new Ford GT and Ferrari 488 GTE will be competing in the GT Le Mans class alongside proven competition machinery. BMW Team RLL reveals 100th anniversary livery for the BMW M6 GTLM race cars in Daytona. Daytona (US), 27th January 2016. BMW Team RLL today revealed two commemorative 100th anniversary liveries for the new BMW M6 GTLM race cars, with which Bobby Rahal's (US) team will compete in the 24 Hours of Daytona (US). The race forms the first round of the 2016 IMSA WeatherTech SportsCar Championship (IWSC). The number 25 car sports a look reminiscent of the iconic BMW 3.0 CSL, which contested its first season of racing in North America back in 1975 and claimed the first victory in Daytona 40 years ago. The second BMW M6 GTLM will race with the number 100. To mark BMW's 100th anniversary this year, its livery looks to the future.
