What engine does the Buick Envision use?
2 Answers
Buick Envision adopts the new 1.5T Ecotec engine (20T). Here are the relevant details: 1. The new 1.5T Ecotec engine (20T) features mainstream engine technologies such as direct injection, turbocharging, and integrated exhaust manifold. 2. With a maximum power of 169Ps (124kW), it can rival many mainstream 1.8T engines. Meanwhile, it delivers a maximum torque of 250N·m within the range of 1700-4400rpm, making it well-suited for urban driving conditions. 3. Like other small-displacement turbocharged engines, the Buick Envision's engine employs a small-size, low-inertia turbocharger, and the addition of an electronic bypass valve enhances turbo responsiveness. 4. The centrally positioned fuel injector ensures more uniform fuel distribution within the combustion chamber, improving combustion efficiency.
The Buick Enclave primarily uses turbocharged engines, with the most common being a 2.0T four-cylinder engine delivering around 260 horsepower and 350 Nm of torque. Paired with a 9-speed automatic transmission, it offers ample power, making highway overtaking effortless. However, specifics vary by model year—newer Enclave Plus or Plus eHybrid models may feature a 1.5T or e-hybrid system, prioritizing fuel efficiency with daily driving consumption around 8L/100km. Personally, I find the engine tuning well-balanced, with early turbo engagement ensuring responsive starts. Routine maintenance should adhere to recommended oil specs, with service intervals every 10,000 km to prevent carbon buildup. Technologically, it employs direct injection and start-stop for performance and eco-friendliness. Buick’s powertrains emphasize efficiency and reliability, offering a sportier feel compared to Japanese counterparts.
