Character mistake: Tej mentions that the BMWs they used were factory-line, ie. unmodified. Hobbs then says that they were twin-turbo V8s "spitting out 560 ponies". The BMW M5s they have are E60 models (2005-2010) powered by a naturally aspirated 5.0 liter V10, producing 507 horsepower. (00:38:30)
Fast & Furious 6 (2013)
1 character mistake - chronological order
Directed by: Justin Lin
Starring: Dwayne Johnson, Vin Diesel, Paul Walker, Michelle Rodriguez
Factual error: In the scene where Shaw is talking to a goon while fixing his car he states the simplest things cause the most problems while holding a spark plug. We know this can't be right as Brian concludes the car is a turbo diesel like a Le Mans car, which would actually use a glow plug and not a spark plug. (00:19:50)
Dominic Toretto: Not bad for a cop.
Hobbs: I never thought I'd trust a criminal. Till next time.
Dominic Toretto: Till next time.
Trivia: When Brian goes undercover as a prison inmate to talk to Braga, his fake name is T. Bridges. Bridges is the real last name of Ludacris who plays Tej, and T is the first initial of Tyrese Gibson who plays Roman. (00:55:25)
Question: Did Laz Alonso reprise his role as Fenix for the flashback sequences, or was it all archive footage?
Suggested correction: That's exactly the problem that Shaw is referring to, a member of his team installed the incorrect plug which caused a problem, i.e. a Spark Plug and not a Glow Plug (a simple thing, causing the problem), along with the 'good' being simple minded and causing the rest of Shaw's team a problem.
The glow plug isn't what causes combustion in a diesel like how a sparkplug does for gas. The wiring harness for a spark plug vs a glow plug is completely different and they aren't interchangeable. You can't just accidentally put a spark plug in a diesel, it doesn't work like that.
