New Buick Engine Powering New Buick Encore Around It

2016 Buick Encore
General Motors announced Monday a new trim for the 2016 Buick Encore that will use a new 1.4-liter turbocharged four, which will be the first application of a new global-engine platform. The car will go on sale this fall.
According to GM, the new mill produces 153 horsepower and 177 pound-feet of torque — an 11 percent gain in power and 20 percent gain in twist over the 1.4-liter turbocharged engine currently doing duty in the cute ute. The two engines share only similar displacements. The current mill is rated at 138 hp and 148 lb-ft of torque.
There’s also a new Encore trim called Encore Sport Touring and it has a spoiler and 18-inch wheels and body-colored door handles and back to the engine.
The aluminum block has been specifically built to reduce friction and increase cooling, GM said in a statement announcing the Buick Encore Sport Touring.
In addition to its aluminum block and heads, GM said low-friction piston rings, camshaft drive and a low-friction oil pump will boost efficiency. A steel crankshaft was used to reduce engine vibration, and steel connecting rods used with aluminum-alloy pistons with low-tension rings will cut weight without sacrificing durability.
The small engine will also use a variable-flow oiling system that matches oil supply with engine load, removing excessive oil pumping. Oil jets will help cool pistons to increase efficiency.
At the other end, the cylinder head has a water-cooled exhaust manifold integrated with its aluminum casting to speed engine warm-up, and gasket seals around the exhaust ports have been removed. GM says both measures will help efficiency and durability, as well as offer “under-hood packaging advantages.”
