2015 BMW X3 arrives with tweaked styling, diesel option

The luxury crossover market has been a huge success for BMW, having sold over a million X3 models worldwide since the CUV first went on sale in 2003, not to mention all of the momentum its had with the larger X5. At the Chicago Auto Show, BMW is unveiling the refreshed 2015 X3, featuring an improved design, a new diesel engine option, and a rear-wheel drive variant.
The X3 is getting some handsome upgrades to the exterior. The twin, circular headlights now extend to touch the slightly widened, chrome kidney grille, to bring the styling in line with the 3 Series and 4 Series. (LED headlights are now optional, as well.) The front bumper gets reshaped brake cooling ducts, and the rear bumper gets a touch of additional metal trim at the bottom. BMW has also added standard LED turn signals in the side mirrors.
BMW has enhanced the interior with added chrome trim, high-gloss black trim around the center console, sliding covers for the cup holders and new interior upholstery designs. The X3 is also getting a major boost in optional technology - there's a new Parking Assistant, as well as an Active Driving Assistant with adaptive cruise control, Lane Departure Warning, Frontal Collision Warning, Pedestrian Warning, and City Collision Mitigation.

Forza Motorsport profiles courageous paralyzed racer

It's easy to look at racing video games as just a time waster or a hobby. In reality, though, they're often powerful tools for aspiring racers to learn tracks, race craft and how to set up a car in an easily accessible, risk-free environment. We aren't just talking about proper computer-based sims, like iRacing. Console-based racers like Forza Motorsport and Gran Turismo provide a test bed for racers of all sorts.
For Mario Bonfante, Jr., a former motorcycle racer that was involved in a brutal accident that left him in a wheelchair with only limited use of his arms, Forza is a bit more. It allows him to perfect the setup of his personal racecar, a heavily modified E46 BMW M3, complete with hand controls.

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.
