Third 1987 Buick Regal GNX will be auctioned in January

A member of the 1987 Buick press fleet is hitting the auction block next year and it's a rarified gem: a low-mileage Regal Grand National GNX, serial No. 003 and one of just 547 models built for that year, and the last of the traditional body-on-frame, rear-wheel-drive Grand Nationals. It'll be auctioned at the Barrett-Jackson Scottsdale Auction in January. The GNX No. 003 was loaned out to publications including Autoweek, Motor Trend and Road & Track, where it racked up around 8,200 miles. "Through it all, a constant sad undertone was the understanding that 1987 was to be the final appearance of the traditional body-on-frame, rear-wheel-drive G-body (which also underpinned the best-selling Chevy Monte Carlo, Pontiac Grand Prix and Olds Cutlass)," reads a the description published on Barrett-Jackson's website. "A totally redesigned W-body Somerset Regal, with front-wheel drive and unitized body construction, was slated to replace the popular midsize Buick in 1988." So Buick opted to make "a Grand National to end all Grand Nationals" with the '87 GNX, partnering with ASC/McLaren to equip them with wheel lip flares, fender vents, 16-by-8-inch BBS rims and more aggressive tires. It left untouched the Grand National's standard Sequential Electronic Fuel Injection 3.8-liter V6 but added a larger Garrett T-3 turbocharger with a ceramic impeller, a larger intercooler, more aggressive fuel, spark and waste gate tables, and a dual exhaust system that boosted output from 235 horsepower and 330 foot-pounds of torque to 276 hp and 360 lb-ft. That was enough, Barrett-Jackson reports, to make the performance coupe quicker and faster in quarter-mile tests than the Ferrari F40 and Porsche 930 Turbo. After making the test-drive rounds in the automotive media, the car sold in 1988 as a brass hat/company official car to Fischer Buick in Troy, Mich. with approximately 8,200 miles on it. From there, it quickly sold to a local resident who drove it very little, and sold it in the spring of 1989. Since 1992, it has reportedly been kept in climate-controlled storage, totally original, unmodified and undamaged, with just 10,790 miles on the odometer today. It recently underwent a complete mechanical service and cosmetic reconditioning. You can check out the listing on Barrett-Jackson here. The first '87 GNX ever produced resides in the General Motors Heritage Collection and No. 002 is at the Sloan Museum in Flint, Mich. Interestingly, another '87 GNX, No.

2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.

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.
