Buick Electra-L, Electra-LT concepts lead the Wildcat to production

Buick loves the Beijing Motor Show, and why shouldn't it? Working with its local partner, SAIC, the brand seems to saves up so much mojo for April in Asia and shows up with stunning designs. Here are another two takes on the brand's latest sheet metal philosophy, penned by the SAIC-GM Pan Asia Technical Automotive Center and riding on GM's Ulitum platform, the Electra-L sedan and Electra-LT wagon concepts. The Electra-L could be seen as a production version of the Wildcat EV concept from 2022 (not the Wildcat from 1985) that launched Buick's new design language. All the major forms and curves are there, so too the turbine-style wheels, but the fastback roof's been stretched to create adequate headroom for a quartet. The edges of the front fascia have been redrawn to be less aggressive and form a canvas for illuminated ornamentation. The four-door stretches 198.3 inches long on a 118.1-inch wheelbase, meaning less than an inch difference in both dimensions between the Buick and the new BMW i5. Power comes from a single motor on the rear axle making 342 horsepower. A battery of unknown capacity is claimed to be good for a 435-mile range under China's CLTC test loop. The light-sensing glass roof hovers over a rectilinear instrument panel with a floating main display and a retractable 7-inch screen for the front passenger, four pressure-sensitive "zero-gravity" seats wrapped in an eco-friendly fabric, and rear quarters with a small inductive cooktop for enjoying tea in the custom tea set.  SAIC and Buick had less to say about the Electra-LT. Looking like the Allroad version of the Electra-L, it's got fender extensions framing the "titanium metal armor" wheel design, an air suspension that can lift the body by 1.6 inches, and that roof box to broadcast its light adventure credentials. Fitted with the same basic interior layout as the sedan, the wagon might add a third row; the description says its "eConnect smart cabin system supports 7-screen interaction." We're not sure if something got left out of the powertrain description, though, as the Electra-LT said to be powered by a 342-hp motor on the rear axle while also possessing "independent four-wheel drive."    Two years ago, Buick said it would introduce five all-new EVs in China by 2025. The sedan is rumored to be headed to the Chinese market next year, a production version perhaps ready by the time of the 2025 Auto Shanghai.

2017 Buick LaCrosse an evolution of sharp Avenir concept

After years as a bloated, uninspiring, but comfortable near-premium sedan, Buick has taken the wraps off a leaner, lither, far more stylish LaCrosse. The third-generation model has just made its debut at the 2015 Los Angeles Motor Show. While there's a lot to talk about, let's first address the new, Avenir-inspired sheetmetal. The fascia is basically the concept car smoothed over into production form, featuring the same winged trishield. In place of the chrome-trimmed waterfall, the LaCrosse gets a blacked-out, recessed grille with a chrome surround. It looks good in photos but it's better in person, adding a real sense of complexity and depth to the front end. The headlights and lower fascia, meanwhile, adhere closely to the concept. The same cannot be said of the LaCrosse's tail. While the taillight lighting pattern is similar, the overall shape of the lighting element is radically different, refining the design featured on the back of the Regal. Also gone, sadly, is the Avenir's boattail rear deck. Instead, the LaCrosse gets a small rear deck that curves up into a pleasant duckbill spoiler. The rest of the tail is pleasantly restrained. Perhaps the weakest point is the profile, where Buick has instituted a "split-spear" design, featuring a strong shoulder line above the rear wheel well, which sits below an even stronger character line that curves down and towards the front of the car. It strikes us as just a little too much, like the Impala. Underneath that sheetmetal, Buick has managed to trim nearly 300 pounds of body fat, nearly half of which came from the vehicle's actual structure. That 300 lbs, according to Buick's engineers, is equivalent to a Kenmore side-by-side refrigerator, in case you needed a helpful comparison. Despite the weight savings, Buick has upped the torsional rigidity for this new model by 15 percent. The LaCrosse's cabin features a strong, cockpit-like design, with a high, floating-bridge center console. This is possible due to Buick's adaption of the Electronic Precision Shift system, introduced earlier this month on the new Cadillac XT5. Despite the new-fangled console design, Buick's retained the wraparound cabin style introduced on the second-gen model. Based on a quick crawl around the interior, space is great in front, although ingress in back is somewhat difficult due to the roofline. You're probably wondering why we haven't said anything about the mechanicals just yet.

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.
