The 2004 Pontiac Bonneville is a full-size sedan that marked the final generation of this iconic nameplate. Introduced in 1957, the Bonneville had been a staple of Pontiac’s lineup, representing both performance and luxury. The 2004 model year represented a significant redesign, bringing a more contemporary and aerodynamic look to the Bonneville, while retaining the traditional spacious cabin and comfortable ride. Under the hood, the 2004 Bonneville was powered by a 3.8L V6 engine producing an impressive 205 horsepower. While this engine provided adequate power for daily driving, it lacked the performance punch that characterized earlier generations of Bonnevilles.

Despite the more restrained power output, the 2004 Bonneville still offered a comfortable and refined driving experience. Features such as a spacious interior, plush seats, and a smooth-riding suspension made it an ideal choice for long road trips or daily commutes. However, the 2004 Bonneville faced stiff competition from other full-size sedans, such as the Chevrolet Impala and Ford Taurus, which offered more modern designs, improved fuel economy, and a wider range of engine options. Ultimately, the 2004 Pontiac Bonneville served as a swan song for this legendary nameplate, marking the end of an era for a car that had become synonymous with American automotive history.
