GM recalling 1.5M cars in China for faulty bracket

General Motors and its Chinese partners have announced their second recall in the People's Republic this year, following a 2,653-unit recall of the Cadillac SRX earlier this year. This latest recall affects nearly 1.5 million cars built between 2006 and 2012. It's not explicitly stated, but as there's no movement from the US NHTSA, we suspect that the cars in question were all Chinese-built rather than imports.
The vast majority of the affected vehicles are Buick Excelles (pictured), with 1.2 million units being recalled over a faulty bracket that's meant to secure the fuel pump. The Excelles in question were built between 2006 and 2012, while an additional 250,000 Chevrolet Sail superminis, built between April 2009 and October 2011, are being recalled for a similar reason.
According to the PRC's Administration for Quality Supervision, Inspection and Quarantine, the faulty bracket could crack and potentially cause a fuel leak.

2018 Buick Regal GS : The 310-hp American hot hatch

Buick has spent the last decade shredding its perception as the low-level luxury vehicle for geriatrics, but the brand hasn't always been associated with that crowd. In fact, ask some enthusiasts and you'll hear about the GM 3800 series engines, IndyCar racing, and the mythical GS and GNX. In that high-octane theme, GM pulled back the curtain on the all-new, all-wheel drive, 310-horsepower 2018 Buick Regal GS Wednesday morning in Milford, MI. The GS is basically a sport-tuned version of the all-new Buick Regal. We've seen the standard and high-riding wagon variants, but this is our first look at what's likely to be the enthusiast pick. The Regal GS uses the five-door sportback bodystyle from the standard car (though a GS version of the TourX would be awesome), swiped from GM's soon-to-be former German division, Opel. While a number of automakers are downsizing engines, Buick is soldiering on with its tried and true naturally aspirated 3.6-liter V6, in this guise making 310 horsepower and 282 lb-ft of torque. Power is sent to all four wheels through a nine-speed automatic. The all-wheel drive system uses a twin-clutch setup and has been tuned specifically for the GS. The Regal GS makes more power than both the Acura TLX A-Spec (290 horsepower) and the Lexus IS350 F-Sport (306 horsepower). The V6 features both cylinder deactivation and auto stop/start for better fuel economy. The fully independent suspension uses the second-gen Continuous Damping Control (CDC), capable of 500 adjustments per second. Selectable modes allow the driver to tailor the car to fit the situation. Large Brembo front brakes are surrounded by standard 19-inch wheels and tires. The exterior gets a few styling changes like a sporty front and rear fascias, a small rear spoiler, and plenty of GS badges. Inside, the Regal GS gets unique sport seats with integrated headrests and adjustable lumbar and thigh bolsters. They even come standard with heating, ventilation, and massaging functions. The driver faces a GS badged flat-bottom steering wheel and GS-specific pedals. A full-color heads-up display is optional. Available safety features include front pedestrian braking, lane keep assist with lane departure warnings, forward collision alert, automatic emergency braking, and adaptive cruise control. The real key for the success of the Regal GS could be pricing.

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.
