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.

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

Opel Cascada close to getting green light for US

For a company with a long tradition of grand touring convertibles, it's almost unseemly that General Motors doesn't offer a properly relaxed four-seat convertible in North America. There's the Chevrolet Camaro, of course, but it's not big on rear-seat space and it doesn't offer that sort of serene demeanor that many open-air buyers crave. We're thinking of something more refined and, dare we say, elegant. Something a bit closer to the Opel Cascada.
The General's front-wheel drive convertible went on sale in Europe this year, and while it seemed like a natural fit for its Buick brand in America, it's never been sold here. That may be about to change, however. Back in June, CEO Dan Akerson hinted he'd like to see the Cascada available in the US, and now there's word from Edmunds that importation "could happen soon." That's according to an unnamed insider at the company.
