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.

Buick Enclave gets continental makeover with Tuscan trim

Buick is trying to lend an air of Italian elegance to the Enclave with its newly announced Tuscan Edition that's available on the crossover for the 2016 model year. Named after the famously hilly and fertile region of Italy, the package brings some bronze accents to the CUV. As the very specific trademark filing for the Tuscan suggests, the special edition adds bronze trim to the uprights in the grille, and the metallic color finds its way into the embellishments on the 20-inch chrome wheels, too. Buyers also get to choose from three shades when ordering the package: White Frost Tricoat, Dark Chocolate Metallic and Ebony Twilight Metallic. Beyond those trim upgrades, the Tuscan Edition is just like any other Enclave. The package can only be ordered on the Leather and Premium trims, and all of their features are still available including a power moonroof, park assist, HID headlights and many luxury features inside. As with the rest of the range, power comes from a 3.6-liter V6 with 288 horsepower and 270 pound-feet of torque that routes through a six-speed automatic. There's also a choice of front- or all-wheel drive. The Italian-inspired CUV makes its debut at the New York Auto Show in just a few days and brings its bronzer to dealers this summer. Buick Introduces 2016 Enclave Tuscan Edition Bronze accents distinguish crossover that ignited brand's renaissance 2015-03-26 DETROIT – Buick today introduced the 2016 Enclave Tuscan Edition – a more distinctive expression of the popular crossover, highlighted by a bronze-tone grille and 20-inch chrome-clad wheels with bronze accents. The Enclave sparked Buick's renaissance eight years ago and continues to fuel its momentum, with 2015 sales building on record sales of 62,300 in 2014. "Buick's quality, refinement and style continues to attract more customers and this modern resurgence started with Enclave," said Duncan Aldred, vice president of Buick. "It was a pioneer for three-row luxury crossovers and remains one of the segment's most popular. The new Tuscan Edition celebrates Enclave's achievement and rewards owners with a higher level of distinction." The 2016 Buick Enclave Tuscan will be on display at the New York International Auto Show and goes on sale this summer on the Leather (1SL) and Premium (1SN) trims. It is offered in three premium exterior colors: White Frost Tricoat, Dark Chocolate Metallic and Ebony Twilight Metallic.

GM recalling 1.4 million older vehicles for oil leak fire risk

General Motors is recalling 1,411,332 older vehicles with its 3.8-liter V6 yet again due to a fire risk. Specifically, there are 1,283,340 of them in the US, and the affected models are the: 1997-2004 Pontiac Grand Prix 2000-2004 Chevrolet Impala 1998-1999 Chevrolet Lumina 1998-2004 Chevrolet Monte Carlo 1998-1999 Oldsmobile Intrigue 1997- 2004 Buick Regal The fault with these vehicles is that oil can drip onto the hot exhaust manifold during hard braking, which can potentially cause of fire. In the last six years, there have 19 reported minor injuries from this problem but no crashes or fatalities, according to the company. Spokesperson Alan Adler also told Autoblog: "GM has reports of 1,345 fires in vehicles that were repaired under two previous recalls for this issue." At this time, GM is still developing a remedy for the problem. According to Adler, the company advised owners to park these vehicles outside for the previous recalls. "The cars can be safely driven. In cases where a customer reported an engine fire while driving, smoke was reported, which would be an indication of a malfunction," he said. This is GM's fourth recall for this problem since 2008, according to The Detroit News. At one point it was believed that aging valve cover gaskets allowed the oil to leak out and drip onto the manifold. A campaign in 2009 covered nearly 1.5 million of these models through the 2003 model year for the same issue. At the time, dealers installed new spark plug wire retainers as a fix.
