The Peugeot 406, particularly the Phase II iteration introduced in 1999, represents a significant vehicle in Peugeot’s history, embodying the brand’s commitment to comfortable and stylish mid-size transportation. While not officially sold in the United States, the 406 was a popular choice in Europe and other international markets from 1995 to 2004. Positioned as a competitor to vehicles like the Ford Mondeo and Volkswagen Passat, the 406 offered a blend of practicality, refinement, and available technology. The 2.2 HDi variant, powered by a direct-injection diesel engine, was a key model in Peugeot’s push for fuel efficiency and reduced emissions.
Peugeot 406 2.2 HDi: A Detailed Overview
The Phase II update of the 406 brought with it subtle styling revisions, improved interior materials, and crucially, the introduction of more advanced engine options, including the 2.2 HDi. This model aimed to provide a compelling alternative to gasoline-powered vehicles, offering comparable performance with significantly improved fuel economy. The 406’s design, penned by Pininfarina, was lauded for its elegant lines and aerodynamic profile, contributing to its popularity as a family sedan.
Engine & Performance
The heart of the 406 2.2 HDi is its 2.2-liter, inline-four cylinder diesel engine, designated the 4HX DW12TED4. This engine produces 133 horsepower at 4,000 rpm and a substantial 314 Nm (231.59 lb.-ft.) of torque at 2,000 rpm. The use of a turbocharger and intercooler significantly enhances performance, providing a responsive driving experience. The engine’s common rail direct injection system contributes to its efficiency and reduced noise levels compared to earlier diesel designs. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 11 seconds, while 0-60 mph is achieved in around 10.5 seconds. The 406 2.2 HDi boasts a top speed of 205 km/h (127.38 mph). The engine’s power-to-weight ratio is 10.6 kg/Hp, and its torque-to-weight ratio is 4.5 kg/Nm, indicating a good balance between power and mass. The engine displaces 2179 cm3 (132.97 cu. in.) and features a compression ratio of 18:1.
Design & Features
The Peugeot 406 Phase II is a four-door sedan with a five-seat configuration. Its body style is characterized by a flowing silhouette and a relatively low-slung profile. The interior of the 406 was designed with comfort and practicality in mind. Features included power steering, ABS (Anti-lock Braking System), and a manual five-speed transmission. The Phase II models often included upgraded interior trim and improved sound insulation. Trunk space is a respectable 430 liters (15.19 cu. ft.). Safety features, while not as comprehensive as modern vehicles, included a robust chassis and the aforementioned ABS system. The 406’s suspension system – independent McPherson struts at the front and an independent multi-link setup at the rear – provided a comfortable ride and competent handling. The vehicle’s dimensions are 4600 mm (181.1 in.) in length, 1765 mm (69.49 in.) in width, and 1400 mm (55.12 in.) in height, with a wheelbase of 2700 mm (106.3 in.).
