Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
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.
Factual error: Brian mentions that the engines in Shaw's flipcars sound like the engines you hear at Le Mans, turbo diesels. These cars have over 500 horsepower and are capable of reaching speeds upwards of 250 miles an hour. They also weigh less than one ton. Shaw's cars seem to meet all these demands: massive power and torque, no body fat and very fast. But here is also a problem: Dom is easily able to keep up in a factory-tuned BMW, which would be nearly twice as heavy, and Hobbs is able to keep up in his "four-wheeled tank", which would be thrice the weight, with even less power. There is no way that an extremely good driver like Shaw wouldn't be able to lose them with such an advantage in terms of power to weight ratios.
Continuity mistake: During the scene where the cable is shot into the sides of the cliffs to stop the convoy, there are no civilians in the area. As soon as the convoy hits the cable and stops, you can see two normal cars just feet away from it. Not only were the cars never there before, but they would have also gotten stopped by the cable.
Continuity mistake: When Roman is fighting the guy on the bonnet of Shaw's Land Rover, Tej signals him to get back on his Mercedes jeep. When Roman does this, the jeeps are pressed up against one another. Then Tej rams Shaw's Land Rover into the jetwash of the plane. Right before he does this, suddenly a massive gap has appeared between the cars.
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.
Revealing mistake: The truck Roman and Tej are suspended in during the runway scene has no prop shaft attached (without it, the truck won't be able to drive at all). When you look at the bottom of the truck while it's in the air, you can see where the shaft was supposed to be attached to the rear differential.
Factual error: When the Mercedes jeep hits the wall at the end of the plane, Shaw goes straight through the windshield and falls to his death in a cloud of shards. Windshields on modern cars, like that jeep, are made out of laminated glass, layers of glass and plastic, precisely designed to prevent shattering into those deadly daggers during an accident and kill the unlucky guy in front of it.
Continuity mistake: Tej tells Hobbs he's got this, and the scene changes to establishing shots around London. The first shot shows a shot of London, featuring many landmarks and Big Ben in the background. The time in the first shot is 2:10. The shot changes with the camera closer to Big Ben and the time is suddenly 3:00.
Continuity mistake: In scenes showing how Letty survived the explosion it shows her crawling out of the car then getting blown down the hill, but in Fast and Furious she is still in the car when Phoenix shoots it, causing the explosion, so she couldn't have been blown down the hill.
Character mistake: Brian compares Shaw's cars to "something you'd hear at Le Mans, a turbo diesel." However, a turbo-diesel is simply a turbocharged diesel engine, fairly popular (and common) in Europe like its non-charged counterpart, due to much better gas mileage and lower price of diesel fuel. On the other hand, WEC (World endurance championship, under which Le Mans 24 belongs) allows lot of variability in engine design. TDI engine was only used by Audi teams and for a short time, by Peugeot. Others used petrol turbo or NA engines.
Plot hole: When the crew is chasing after Shaw and his gang. Shaw's goons plant bombs on their cars. The bomb on Brian's car is in a location that technically Brian wouldn't have even known that it was there. If this bomb was somewhere he couldn't see it, then Brian wouldn't have been able to clip the pole to make it fall off.
Continuity mistake: At the shoot out, Gisele is talking with the wounded man who made the gadgets. He has a small amount of blood spilling out of his mouth, down the side of his cheek. A couple of shots later, the blood is now a long streak down his cheek. Then it is suddenly just a tiny smear of blood around the edge of his mouth.
Continuity mistake: Roman removes a 100 Grand bar from the shot-down vending machine. In the close-up shot, there are several other 100 Grand bars visible. One of them is held by springs on both sides, with the left side slightly raised. In the next shot, that specific bar has vanished from the pile.
Factual error: Roman is searching through the shot-down vending machine after the massive chase. Two of the products shown in the machine are a couple of Nestle 100 Grand bars and a couple of Nestle Butterfingers bars. This scene takes place in the UK - 100 Grand bars and Butterfingers bars aren't available in vending machines in the UK, just specialist sweet shops.
Other mistake: The Underground fight was apparently filmed in Aldwych Tube station, which is unused. When Letty jumps on the train the underground sign has "ras" at the end, probably saying "St. Pancras." When Hobbs heads to the CCTV office, he claims they got attacked in Waterloo Station.
Continuity mistake: When Brian and Mia are in the red Alfa on the runway, Vegh comes after them in one of the flip cars. Brian turns the car around to trick her into crashing into the barriers but after the turn the red Alfa is still going towards the plane so to speak, and Vegh is going in the opposite direction. When she crashes, the red Alfa is suddenly going the other way, away from the plane.
Factual error: After Letty and Riley fall down the stairs in the tube station, Letty jumps onto an unpainted train that has a Northern Line map inside. The London Underground hadn't had an unpainted train in service for almost ten years when the movie was released, and the train is also the wrong style for the Northern Line.

Continuity mistake: Shaw parks his Mercedes on the left side of the plane facing forward. Dom then comes in and parks his Charger on the right of the Mercedes, also facing forwards. But when Shaw wants to drive out of there, the Mercedes is now facing backwards, and it and the Charger have switched sides. Now the cars did move around a little when the plane was leaning, but this does not explain how the Charger would have moved "uphill".
