Daniel's Taxi is a Peugeot 407, replacing the Phase 1 and Phase 2 Peugeot 406 models used in the first three films. It's likely to be the 3.0-litre V6 petrol engine, though unusually the highest performance model in the range was a diesel. Most of the Marseilles police fleet in the film is also made up of Peugeots, mostly the 206 and 307, while Commissaire Gibert's car is a 607.
First film in the series which does not feature the song "Misirlou" as performed by Dick Dale during the opening credits. Instead, "Pump It" by The Black Eyed Peas, which samples Dale's version, is used.
