Buick Riviera Concept hits the floor in Shanghai

Here we have a concept in the true sense of the term. The Buick Riviera you see here - the name of which was last used in production back in 1999 - is said to preview Buick's future styling direction, which means we should expect to see more flowing body shapes to go along with new versions of the marque's classic waterfall grille design. Oh, and we don't believe there's a single porthole in sight.
Powered by Buick's so-called dual-mode wireless plug-in hybrid electric vehicle propulsion system (we'll stick with the W-PHEV acronym) that allows the car to be charged wirelessly just by driving atop a special charging mat on the ground, the car's powertrain is just as futuristic as its exterior shape.
Other high-tech bits include holographic projections on the windshield showing the driver what's around him, with input coming from 10 high-res cameras and 18 micro high-precision sensors. The car also sports 4G wireless connectivity so that its occupants are always connected.

2021 Buick Envision's bold design means small space gains, a few big losses

So far, every preview we've had of the 2021 Buick Envision compels us to believe that it isn't playing in the same league as the current Envision, nor is it playing the same sport. The chiseled, crisp exterior is matched by an interior that, in pictures at least, sends a genuine premium message. GM Authority got early intel on dimensions for the new crossover, the numbers showing that the only close relationship between the current and the new Envision is in size. According to GMA, the 2021 Buick will be 185.5 inches long on a wheelbase of 109.4 inches, it'll stand 74.1 inches wide without mirrors, and 64.6 inches tall. Front and rear tracks are matched at 63.3 inches. That makes the new version 1.8 inches longer than the current five-seater, with a wheelbase stretched 0.9 inches, while width is 1.7 inches wider but overall height is 2.2 inches lower. The track has been expanded by 1.3 inches front and back. The four-trim lineup will be base, Preferred, Essence and Avenir. Buick's website pegs the current Envision at the single curb weight of 3,755 pounds. GMA writes that the new car comes in at 3,685 pounds in base form, or 3,932 in top Avenir trim. Those could all represent weights for front-wheel-drive models. AWD will be optional on all but the base 2021 Envision. The price for edgier design is a tiny cut in interior room in front. In the coming crossover, front headroom shrinks 0.4 inches to 39.6 inches, front legroom shrinks by 0.5 inches, front shoulder room goes down by 0.3 inches. Front hip room gains 0.7 inches, however, Occupants in the row behind get a tiny bit more space in two dimensions, rear headroom going up 0.4 inches, rear legroom by 1.8 inches, Rear shoulder room gets shaved 0.7 inches, and those haunches on the 2021 model take a bite out of rear hip room, that spec dropping by 5.7 inches to 47.4.  Cargo room sees a slight dip, too, there being 25.2 cubic feet of space behind the second-row of seats compared to 26.9 feet available now. The gap grows with the rear seats down, the coming Envision able to swallow 52.7 cubic feet behind the front row, the current Envision managing 60 cubic feet.  When product starts showing up on dealer lots, we're to expect a 2.0-liter turbocharged four-cylinder under the hood with 230 horsepower and 258 pound-feet of torque, shifting through GM's nine-speed automatic transmission. GMA believes pricing will start around $34,000, which would be about $500 more than the current Envision.    

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.
