The Peugeot 406, launched in 1995, represented a significant step forward for the French automaker, aiming to compete directly with established mid-size offerings from manufacturers like Ford, Vauxhall/Opel, and Volkswagen. The 406, specifically the Phase I models produced between 1995 and 1999, was a popular choice in Europe, known for its comfortable ride, stylish Pininfarina-designed exterior, and relatively affordable price point. While never officially sold in the United States, the 406 provides a compelling example of European automotive engineering of the era, prioritizing practicality and driving experience. This article details the 1.8-liter (90 horsepower) version of the 406, a common engine choice within the range.
Peugeot 406: A European Mid-Size Sedan
The Peugeot 406 was designed to replace the aging Peugeot 309 and 405 models. It was available in saloon (sedan), estate (wagon), and coupe body styles. The Phase I models, produced from 1995 to 1999, were characterized by a specific front-end design and interior appointments. The 406 aimed to offer a more refined and modern alternative to its predecessors, with a focus on comfort, safety, and a more appealing aesthetic. It quickly became a mainstay in the European D-segment, competing with vehicles like the Ford Mondeo, Opel Vectra, and Volkswagen Passat.
Engine & Performance
The 1.8-liter engine powering this variant of the Peugeot 406 is a naturally aspirated, inline four-cylinder unit, designated LFX XU7JB. It produces 90 horsepower at 5000 rpm and 147 Nm (108.42 lb-ft) of torque at 2600 rpm. While not a performance-oriented engine, it provided adequate power for everyday driving and cruising. The engine’s power-to-weight ratio is 72 horsepower per tonne, and the torque-to-weight ratio is 117.6 Nm per tonne. The engine features multi-port fuel injection and an overhead camshaft (OHC) valvetrain. The 1.8-liter engine is known for its reliability and relatively low running costs, making it a popular choice for fleet buyers and private owners alike. The engine displaces 1761 cm³ (107.46 cu. in.) and has a bore of 83 mm (3.27 in.) and a stroke of 81.4 mm (3.2 in.). It is paired with a five-speed manual transmission, driving the front wheels. Fuel economy is rated at 8.4 l/100 km (28 US mpg, 33.6 UK mpg), with combined CO2 emissions of 205 g/km.
Design & Features
The Peugeot 406 Phase I is a four-door sedan with a sleek, aerodynamic profile penned by the renowned Italian design house Pininfarina. The exterior styling was considered modern and elegant for its time, featuring a sloping roofline and integrated headlights. The interior was designed with practicality and comfort in mind, offering seating for five passengers. Standard features included power steering, ABS (Anti-lock Braking System), and a relatively spacious trunk with a minimum capacity of 430 liters (15.19 cu. ft.). Safety features, while not as comprehensive as modern vehicles, included ABS and a robust body structure. The 406’s suspension system – independent McPherson struts at the front and an independent multi-link setup at the rear – contributed to a comfortable and controlled ride. The vehicle’s dimensions are 4600 mm (181.1 in) in length, 1765 mm (69.49 in) in width, and 1396 mm (54.96 in) in height, with a wheelbase of 2700 mm (106.3 in).
