Spy photos of the upcoming Buick Regal wagon, via the Opel Insignia

We're pretty sure Buick is working on a Regal wagon. And because the Regal is the Opel Insignia on the other side of the pond, these spy photos show us what's in store when it eventually turns into a Buick. The rakish wagon was lightly camouflaged, giving us our best look at the upcoming vehicle. The wagon shares a lot of the same design cues as the Insignia sedan that we spotted earlier. The bottom of the front end is covered in heavy camouflage, masking the wagon's grille. It's unsure to tell whether the black nostril-like pieces sitting above the grille are vents or just tape. The prototype still shares the same upright nose as the model we spotted earlier, giving the wagon a wider stance than its predecessor. The side profile of the wagon is sleeker, thanks to the extra four inches between the axles, than the current model is, with the design mimicking that of a shooting brake instead of a traditional wagon. The rear end of the wagon is also more upright with the taillights and bottom part of the fender jutting out beyond the glass. The boxy design sitting atop of the rear end doesn't match the rest of the vehicle and appears to be a part of the car's camouflage. With the tunnel-like design at the top gone, the rear end would have a more streamlined design. With the next Regal expected to continue on as a rebadged Insignia, the likelihood of a Regal Wagon in the US look good, but aren't set in stone. Late last year, Buick filed two trademarks for "Tourx" and "Regal Tourx," pointing towards a high-riding wagon with all-wheel drive. Imagine these spy shots with a taller suspension and some crossover-inspired trim pieces and you have a wagon that could take on the likes of the Subaru Outback and Audi Allroad.

Buick Avenir concept struts into Motown

We love auto show surprises, and Buick has already gifted us a sparkly package on the eve of the 2015 Detroit Auto Show. Dubbed Avenir, this four-door concept is said to signal the future of the Trishield brand by previewing a possible flagship sedan. Incorporating time-honored Buick design hallmarks like the sweep-spear profile, Ventiports, and even a subtle boattail rear-end, the four-place sedan is powered by a surprisingly real-world powertrain – namely a next-generation V6 with cylinder deactivation and stop/start, with the most interesting part of the driveline arguably being a "twin-clutch all-wheel-drive system" and a nine-speed automatic gearbox with paddle shifters. Make no mistake, this is a big car. At 204.5 inches long, it's longer than a standard-wheelbase Cadillac Escalade – a span that's emphasized by the car's long hood and waterfall grille – though it's not quite as wide. While clearly a showcar, the beautifully crafted interior looks largely produceable, including attributes like a next-generation 12-inch touchscreen infotainment system and 4G LTE wifi, but we suspect a production car would pick up a third rear seatbelt and give away some of its flowing contours that are said to have been "inspired by nature and sea waves receding on a beach." No word yet on whether there's actually a showroom future for a car like this – it could simply be an exercise designed to test the waters for a next-generation LaCrosse. After all, sedans aren't exactly popular concept fodder these days, especially as crossovers continue to eat into traditional sedan sales in many of the world's markets. However, China still loves the coddling rear seats of a proper four-door sedan (which in this case include silk and bamboo elements), and with a majority of Buick sales happening in the People's Republic, the Asian nation controls the destiny of this General Motors brand. Said another way? Anything is possible, especially with General Motors known to be working on a large flagship sedan for Cadillac already – the Avenir is reportedly based on the same Omega architecture that will underpin the forthcoming CT6. What do you think? Is this a promising direction for the resurgent Buick? Scroll through our gallery, check out the video, and then have your say in Comments.

The new Opel Insignia might be a great Buick, but it's a sad Holden Commodore

Since the first shots of the uncovered Opel Insignia hit our inboxes, we've been filled with excitement for the new sedan. It looks great, it should come to America with little to no visual changes as the Buick Regal, and we might even get a wagon version. Unfortunately, there's a lead lining to this silver cloud, and it comes to us from Down Under. You see, the Opel Insignia is also undergoing a re-badging job in Australia to become the new Holden Commodore. It's replacing the beloved rear-drive Commodore (with an optional V8 and ultra-high performance HSV variants) with a front-drive-based platform offering four- or six-cylinder engines. This is depressing news considering the Zeta-platform underpinning the Commodore VF spawned the Pontiac G8, Chevrolet SS, and fifth-generation Camaro. Knowing this was going to happen doesn't help much either. What makes it all worse is that the new Commodore doesn't have a shred of unique styling in the bodywork. That's not an exaggeration. A new grille with a Holden lion badge instead of an Opel lightning bolt badge is the only change. See for yourself in the Insignia gallery below. Not only did GM erase a unique Australian model, it didn't even allow the brand to give the car a distinct shape. It's sort of like when Ford planned to replace the Mustang with the Mazda-derived Probe. The Probe wasn't that bad for the time, but it was no Mustang. At least in that case the Mustang survived. View 12 Photos Before we get ourselves too down, we should mention that there are reasons to be hopeful for the future. For one thing, the new all-wheel-drive Commodore/Insignias will come with a version of the GKN-developed rear differential found in the Focus RS and Range Rover Evoque, which is pretty neat on its own. And Opel/Vauxhall have always had wild performance versions of the Insignia and its Vectra predecessor. The last one made 325-horsepower and had all-wheel-drive. A new one would likely produce much more, since one of the available V6s makes 308 horsepower. Then imagine all of that extra hypothetical horsepower hooked up to the all-wheel-drive system that introduced us to "drift mode." Not only that, but rear-drive Holdens may not be completely dead yet. A Belgian man announced his intention to buy an old Holden factory along with the tooling and rights for the car once it was discontinued. His plan is to continue producing the old model after Holden is done with it.
