Start with what the Peugeot 607 is: a 4-door saloon with Petrol engine, built from 1999 to 2008, when airbags, anti-lock brakes and Japanese build quality became the world standard. What it meant takes a little longer. The shape is credited to Murat Günak. 168,875 were built.
Where it came from
The Peugeot 607 is an executive car produced by the French manufacturer Peugeot from September 1999 to June 2010. The 607, along with the smaller 407, were superseded by the 508 in March 2011.
Under the skin
The engine is Petrol engine; other versions carried different engines, listed in the specification table below. On the scales it comes to 1610 -. Drive goes through a 5/6-speed manual / 4/6-speed automatic. The layout matters: the engine drives the front wheels, the packaging choice that gives a small car a big cabin. The wheelbase is 2800 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
In the Peugeot line-up the Peugeot 607 has a clear place: it replaced the Peugeot 605; it handed the line to the Peugeot 508; the factory was Sochaux. The cars a buyer would have weighed it against include the Toyota Yaris, the BMW X5, the Honda S2000. Nearby in the Peugeot catalogue sit the Peugeot Onyx and the Peugeot Pars.
