The styling of the 406 is heavily influenced by its predecessor, the 405, which began to be phased out from the 406's launch in September 1995, and eventually finished production in Europe in 2003, when the last estate models were discontinued. United Kingdom sales of the 406 began in February 1996.
Initially, the car was available with 1.8 L and 2.0 L petrol and 1.9 L turbodiesel engines, followed by a turbocharged 2.0 petrol, 3.0 (2946cc) V6 petrol, and 110 bhp 2.1 L turbodiesel. The diesel versions were very popular, and the 406 became one of Europe's best-selling diesel-powered cars.
The 2-door coupé was both designed and manufactured by Italian design studio Pininfarina, with choices of a 2.0 L 4-cylinder engine or a 3.0 L V6, and from 2001, a 2.2 L HDi diesel engine. On later models, a 2.2 L petrol engine was available. Total of 107,633 coupés were made.
For its final year on sale in the United Kingdom, the model was simply called the Peugeot Coupé, with the 406 branding dropped from the name. The 406 was notably successful in the United Kingdom, having broken into the country's key fleet sales market, with a high percentage of units becoming company cars and taxis.
