Designed by Murat Günak on PSA’s PF2 platform, the 307 launched in 2001 with a taller glasshouse and roofline than most C-segment rivals, aimed at outright cabin space rather than a sporting stance.[1] Build quality and reliability drew criticism in its early years (it sat at the bottom of the ADAC’s German breakdown statistics for cars of its age in 2009), though Peugeot’s June 2005 facelift is credited with improving both. A diesel-electric hybrid prototype, claimed to return 83 mpg, was announced in 2006 but never reached production before the 307 itself was replaced.
Three trims are recorded: the mainstream 1.6 16v petrol, the most powerful naturally aspirated 2.0 16v, and the 16-valve 2.0 HDi diesel introduced from model year 2004. Every horsepower figure in the source is explicitly labelled PS, so the conversions here carry no reading ambiguity, unlike several other Peugeots of this era. No top speed, 0-100 km/h time or manufacturer kerb weight is published in the source; a kerb weight is recorded for the 1.6 16v only, sourced from a single Netherlands-registered car rather than a manufacturer specification.
