Versions
The 405 range included three petrol engines and two diesel engines, all four cylinders, in a variety of states of tune and specification. The range was tailored to suit different export markets. The 1.6 litre saloon featured a low drag co efficient of, with other models varying up to. The 1.4 litre (1,360 cc) engine was fitted with a four-speed manual gearbox. It produces 70 hp-metric at 5,600 rpm.
The 1.6 litre (1,580 cc) engine was fitted with a five speed manual gearbox and produced 92 hp at 6,000 rpm. The 1.9 litre (1,905 cc) engine was available with a five speed manual gearbox, with an option of an automatic in the lower powered version.
The eight valve version of the 1905 cc engine was available in two levels of tune; 110 hp-metric or 125 hp-metric, with numbers varying somewhat depending on the year and the market. A 16-valve version was available with the Mi16 model and this produced 160 hp-metric at 6,500 rpm and could reach a top speed of 220 km/h.[11] The catalyzed version produces 148 hp-metric with a top speed of 214 km/h.
In 1992, the range was facelifted. While the changes were deep, including a modified bottom plate and chassis structure, the design was almost indistinguishable from the pre-facelift model.
The windscreens became bonded; all of these changes increased torsional rigidity considerably while still allowing a deeper opening for the bootlid of the sedan.[12] The taillights were also redesigned and the trim piece between them removed, all in the image of the bigger 605. The interior was also redone, with an all new dashboard and door trim, inheriting many detail parts as well as the overall appearance from the 605.[12]
In April 1993, the T16 was introduced to celebrate the successes of the competition model, with a 2.0 litre 16 valve turbocharged XU10J4TE engine with water cooled chargecooler, constant four wheel drive with 53/47% power distribution and self regulating hydraulic rear axle. It was never built in a right hand drive model.
The T16 produced 200 hp-metric at 1.1 bar (normal boost) or 220 hp-metric at 1.3 bar (overboost) which lasts for 45 seconds. 1,061 examples were built,[13] with ten of these being delivered for use by the National Gendarmerie.[14] The diesel engine options included a 1.9 litre (1,905 cc) unit producing 70 hp-metric at 4,600 rpm or a turbocharged 1.8 litre (1,769 cc) unit producing 90 hp-metric.
