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.

Next Opel Insignia to adopt sleeker looks

The very first set of spy photos of the next-generation Opel Insignia have dropped, giving us a look at the more svelte, aggressive, and stylish look of the popular sedan. As a reminder, the Insignia is sold here in the United States as the Buick Regal. There's only so much we can discern from these photos, thanks to the very heavy camouflage. But we can get a look at the new Audi A7-like roofline, which our spies citing similarities to the Opel Monza concept car from the 2013 Frankfurt Motor Show. The Monza link fits with our previous reports, which claimed the gullwinged wagon would serve as a prime source of inspiration for both the Insignia and US-market Regal. Aside from the significantly redesigned sheetmetal, Opel is also increasing the size of its flagship sedan, adding nearly four inches between the axles. According to our spies, the goal is to build a vehicle comparable in size to the Skoda Superb, a roughly Volkswagen Passat-sized sedan based on the VW Group's MQB platform. What's most interesting for US customers, though, is the body style shown here. Like the aforementioned A7, the next Insignia will be offered as a five-door model, rather than a traditional sedan. The five-door hatch would later be joined by a traditional wagon. It's unclear whether the US market Buick will take a similar route, or whether General Motors will demand a four-door variant exclusive to North America. Check out the spy photos above, and keep an eye open for more on the next Insignia/Regal. Don't plan on seeing it at an auto show any time soon, though. It's not slated to debut until the 2017 Frankfurt Motor Show.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.
