Buick introduced the all-new 2013 Encore at the Detroit Auto Show. Encore, a luxury small crossover powered by an Ecotec 1.4L turbo four-cylinder/six-speed automatic powertrain, will compete with vehicles such as the BMW X1 and Audi Q3.

The engine generates an estimated 140 hp (103 kW) and 148 lb-ft of torque (200 N·m) between 1,850 rpm and 4,900 rpm. The wide rpm range for the maximum torque—a specific trait of turbocharged engines—helps it deliver a better driving experience and performance.
The 1.4L’s turbocharger is integrated within the exhaust manifold for reduced weight and greater packaging flexibility. A reinforced crankshaft and forged connecting rods deliver additional strength to support the engine’s pressurized power and torque over a wide rpm band.
Several of the engine’s features contribute to the Encore’s overall fuel efficiency, including:
- A high-efficiency alternator;
- Regulated voltage control;
- Electronically controlled returnless fuel system; and
- Deceleration fuel cut-off.
They complement other vehicle-wide systems and components that also help improve efficiency, including low-rolling-resistance tires, a column-mounted, variable-effort electric power steering system, neutral idle feature and optimized aerodynamics.
A Hydra-Matic 6T40 six-speed automatic transmission backs the Ecotec 1.4L turbo engine. It is part of a family of six-speed front and all-wheel drive transaxles developed for small cars and crossovers. It has a unique design, with the planetary gearsets positioned on the same axis as the engine crankshaft centerline, making the entire powertrain unit shorter fore-to-aft. This design enables a shorter overall vehicle length, increased interior space, enhanced safety crush zones and lower weight.
The Hydra-Matic 6T40 offers a “steep” first gear and a “tall” overdrive top gear to achieve a wide ratio spread of 6.14:1. This allows the Encore to achieve robust acceleration, as well as fuel efficiency and lower engine noise at highway cruising speeds. A neutral-gear disengagement feature helps enhance smoothness and efficiency.
The new Encore is built on a global small-crossover platform and engineered with a “one-tire” philosophy. Everything is optimized around a single 18-inch tire specification, designed for more precise suspension tuning, driving refinement, quietness and a feeling of control.
The Buick Encore will begin arriving at US Buick dealerships in the first quarter of 2013.
