The Buick Allure was offered with 3 different engines, a 3.6 liter V6, 3.8 liter V6 or a larger 5.3 liter V8 engine. The 3.6 liter used in Buick, Cadillac, GMC, Pontiac and Saturn vehicles. As common as it sounds, the 3.8 liter V6 engine was used much more widely than the smaller 3.6 engine.

The 3.8 liter engine offered better performance and was very reliable. The largest engine offered, the 5.3 liter V8 was one of the most reliable engine GM has ever produced. It offered its customers good fuel economy, good performance and outstanding reliability. A version of this 5.3 liter engine is still being produced today.
