BMW Vision Gran Turismo takes M235i Racing to the virtual extreme [w/videos]

Late last year, Mercedes-AMG worked up a concept car called the Vision Gran Turismo. It presented it at the Los Angeles Auto Show, but that wasn't the point: the point was that it would feature in Gran Turismo 6 on the PlayStation 3. It wasn't the first concept created specifically for the popular driving simulator - following similar projects by Citroën and Red Bull Racing - and as we reported just a month later, it wouldn't be the last. What we have here is the next.
Looking like an even more extreme version of the M235i Racing, the BMW Vision Gran Turismo concept builds on "the tradition of the successful BMW touring cars of the 1970s" in a heart-pumping, if unfortunately strictly virtual form. It's got more extreme aero than the aforementioned M235i Racing and a striking take on the M division's signature light blue, dark blue and red stripe over white livery.
Underneath the digital bonnet sits the same 3.0-liter inline six as the M235i, but pumping out a prodigious (if theoretical) 549 horsepower - far more than the 333 hp in the actual Racing version or the 320 hp in the roadgoing model. Of course BMW has given it an ideal 50:50 front-rear weight distribution and a curb weight of 2,600 lbs - nearly a thousand pounds less than the roadgoing M235i.

2015 BMW 4 Series convertibles recalled to fix airbag programming woes

A problem with the airbags on the 4 Series convertible has promoted BMW and the National Highway Traffic Safety Administration to issue a recall for some 2,000 vehicles across the United States. The issue, according to the notice below, relates to the driver's side front airbag, whose timing for deployment may be off. And if the airbag doesn't deploy at the right time in the event of a crash, that's more likely to result in an injury. As a result, BMW of North America is calling in 2,067 vehicles – specifically the 428i, 428i xDrive, 435i and 435i xDrive convertibles of the 2015 model year and manufactured between October 22, 2014, and February 27, 2015. Those units will simply need to have the software in the airbag control module reset, and will begin undertaking that process in April.Related Video: Report Receipt Date: MAR 13, 2015 NHTSA Campaign Number: 15V148000 Component(s): AIR BAGS Potential Number of Units Affected: 2,067 Manufacturer: BMW of North America, LLC SUMMARY: BMW of North America, LLC (BMW) is recalling certain model year 2015 428i Convertible, 428i xDrive Convertible, 435i Convertible, and 435i xDrive Convertible vehicles manufactured October 22, 2014, to February 27, 2015. Due to a programming error, the driver's front air bag deployment timing may be incorrect. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection." CONSEQUENCE: If the driver's front air bag deployment timing is incorrect, there is an increased risk of personal injury in the event of a vehicle crash. REMEDY: BMW will notify owners, and dealers will reprogram the air bag control module with corrected software version, free of charge. The recall is expected to begin in April 2015. Owners may contact BMW customer service at 1-800-525-7417. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

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.
