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.

Opel to electrify all model lines by 2024, speeding PSA transition

What do you see in the Opel logo? That's right, a lightning bolt. As the German automaker dramatically restructures its future plans, electric cars are in the core of Opel's survival. With attempts to stop leaking money, Opel is speeding up its secession from GM technology, launching nine new models by 2020 with the aim to complete transition to PSA hardware by 2024, leaving only two Opel platforms. This is all part of Opel's freshly announced PACE turnaround plan, which is crucial for the company's survival, according to CEO Michael Lohscheller. "PACE will unleash our full potential. This plan is paramount for the company, to protect our employees against headwinds and turn Opel/Vauxhall into a sustainable, profitable, electrified, and global company," says Lohscheller. Competitiveness will be improved by reducing per-car costs by 700 euros, and by cutting marketing costs by 10 percent. Regarding Vauxhall's future, the statement still includes the British brand. When the Opel sale agreement was reached between PSA and GM in March, the plan was to start implementing PSA technology in 2019, completing the transition in eight years, as Automotive News says. The new business plan is noticeably faster. By 2020, with full access to PSA's electric tech, Opel would have a fully electric next-generation Corsa hatchback and a PHEV version of the Grandland X SUV, which is already based on Peugeot's 3008 model. Currently, there are nine Opel platforms and 10 engine families. By 2024 there should be two platforms and four powertrains; the number of diesel engines in use remains to be seen, and all product lines would include an electrified model. There would be an SUV and a midsize vehicle based on PSA's EMP2 architecture, with the former built in Eisenach — formerly known as the town that built East German Wartburg cars before its Opel era — and the latter built in Russelsheim, where Opel HQ is located. The Russelsheim hub will become PSA's global "competence center," where all Opel/Vauxhall vehicles would be engineered — not Paris. Plans include avoiding any factory closures or personnel layoffs. The PACE statement also mentions Opel's entrance to all of 20 new export markets, with a specific mention of China and Brazil, countries which have traditionally seen Opels sold as Chevrolets. Will the United States be included in that export plan?

Best car infotainment systems: From UConnect to MBUX, these are our favorites

Declaring one infotainment system the best over any other is an inherently subjective matter. You can look at quantitative testing for things like input response time and various screen load times, but ask a room full of people that have tried all car infotainment systems what their favorite is, and you’re likely to get a lot of different responses. For the most part, the various infotainment systems available all share a similar purpose. They aim to help the driver get where they're going with navigation, play their favorite tunes via all sorts of media playback options and allow folks to stay connected with others via phone connectivity. Of course, most go way beyond the basics these days and offer features like streaming services, in-car performance data and much more. Unique features are aplenty when you start diving through menus, but how they go about their most important tasks vary widely. Some of our editors prefer systems that are exclusively touch-based and chock full of boundary-pushing features. Others may prefer a back-to-basics non-touch system that is navigable via a scroll wheel. You can compare it to the phone operating system wars. Just like some prefer Android phones over iPhones, we all have our own opinions for what makes up the best infotainment interface. All that said, our combined experience tells us that a number of infotainment systems are at least better than the rest. WeÂ’ve narrowed it down to five total systems in their own subcategories that stand out to us. Read on below to see our picks, and feel free to make your own arguments in the comments. Best infotainment overall: UConnect 5, various Stellantis products Ram 1500 Uconnect Infotainment System Review If thereÂ’s one infotainment system that all of us agree is excellent, itÂ’s UConnect. It has numerous qualities that make it great, but above all else, UConnect is simple and straightforward to use. Ease of operation is one of the most (if not the single most) vital parts of any infotainment system interface. If youÂ’re expected to be able to tap away on a touchscreen while driving and still pay attention to the road, a complex infotainment system is going to remove your attention from the number one task at hand: driving. UConnect uses a simple interface that puts all of your key functions in a clearly-represented row on the bottom of the screen. Tap any of them, and it instantly pulls up that menu.
