GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

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.
