Buick Riviera Concept debuts in China

It's nighttime in China, and Buick has just concluded an evening event the day before the first - and only - press day of the Shanghai Motor Show. The star of this evening's party was the Buick Riviera concept vehicle, a plug-in electric hybrid coupe that the automaker says gives a glimpse at its future design direction, not to mention resurrecting some nomenclature from the brand's history that includes a similarly named concept from 2007.
The shape of the Riviera is said to be inspired by water. While the traditional Buick "waterfall" grille is present, the front end gains a more aggressive note thanks to what appear to be vertical air inlets below each headlight.
As for the concept's drivetrain, Buick says it uses General Motors' new dual-mode wireless plug-in hybrid electric vehicle propulsion system, or W-PHEV for short. The keyword there is 'wireless,' as the Riviera can charge its onboard battery packs with a traditional cable or wirelessly via a "sensory recharge panel" underneath the car.

Junkyard Gem: 1997 Oldsmobile Eighty-Eight LSS Supercharged

Oldsmobile got terminated by The General in 2005, in part because the marketing suits decided that the first three letters of the marque's name made the cars undesirable to the under-75 set (never mind that 21st-century rappers continue to venerate Oldsmobiles). Not long before the demise of Olds, though, you could buy an Eighty-Eight with the supercharged L67 V6, known as the Luxury Sports Sedan or LSS. These cars are very rare today, but I spotted this '97 in a Denver self-service wrecking yard. These Eaton blowers are now so easy to find in wrecking yards that most of them go unpicked by customers. The going rate for this supercharger is about 50 bucks, because everyone who wants one already has a big hoard of the things. If you have ever wanted to drop a supercharger onto your crapcan race car's engine, now is the time. Performance was respectable for the era, with output of 240 hp and 280 lb-ft. The 3800 was the descendant of the ancient Buick V6, which debuted way back in 1962, so GM had had many decades in which to make it a dependable (though not very smooth-running) powerplant. Yes, you could still buy big ol' sedans with rear drums at the dawn of the 21st century. Did the LSS steal any sales from potential BMW or Mercedes-Benz buyers? Probably not many, though its $27,695 price tag must have looked pretty tempting when compared to that of the much slower $32,960 Lexus ES 300 in 1997. Right now is the best time to make a resolution you'll enjoy sticking with. The reviewers at Popular Mechanics were unable to break the first-year LSS.

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:
