Skoda Fabia was doing about 89mph before crash
DS Coe described how the 999 recording, in which the crash is heard, and the automatic numberplate recognition (ANPR) camera image from before the crash, allowed him to calculate how fast the Skoda was going and he calculated it was travelling at about 89mph.
Audi TT telemetery data shows speed and location of car during pursuit
The jury has previously heard that the Audi TT being driven by Rekan Karwan was a loan vehicle Mahek Bukhari was using because her own Audi was being repaired. Mr Thompson told the jury it may have not been known by her that the vehicle had a telemetery computer, reporting and recording its speed and location, as well as reporting high speeds and even sudden turns.
DS Coe is taking the jury through the data and how fast the Audi was going at each point during the 999 call from Saqib to a 999 police operator.
Audi doing 100mph as Skoda driver reports car 'right behind me'
As the jury listen through sections of the 999 call, DS Coe tells them the Audi telemetery computer registered a "high speed event" at 1.32am as the car's speed reached 100mph.
Moments later the cars all pass the ANPR camera, which catches the Skoda and Audi's numberplate, but the Seat Leon is so close nexgt to the Skoda its numberplate is not visible. One headlight of the Seat Leon can be seen through the Skoda's windows, according to the prosecution.
DS Coe agrees the headlight visible is the light of the Seat Leon
Mr Thompson asked DS Coe about the visible headlight from the pursuing vehicle. He tells the jury the headlight is shining through the driver's door window and the windscreen of the Skoda Fabia and he believes it to be the headlight of the Seat Leon.
DS Coe confirms impact can be heard on 999 call
The jury was played the final moments of the 999 call at 1.32am, in which Saqib can be heard shouting: "Oh my god! No!" before a low, crunching sound is heard and the call ends.
Mr Thompson asked DS Coe: "You can actually hear the sound of an impact?" DS Coe replied: "Yes."
Police used their own Skoda Fabia to recreate crash
DS Coe is back in the witness stand and describing how officers recreated the crash. With the Skoda Fabia being so badly damaged, they used a 2008 police-owned Skoda Fabia instead.
Having the cars to compare to each other, DS Coe was able to look at the damage to the Seat and judge whether each section of damage was likely to have been caused in an impact with the Skoda.
He confirms that damage found on the Seat Leon had been caused by a collision between the front, passenger side of the Seat Leon and the rear, driver's side of the Skoda Fabia.
'Just try to explain to us in lay language what is going on'
It's all getting a bit technical with talk about the relative speeds of the two vehicles - the Seat Leon and the Skoda Fabia - when they collided. DS Coe said there was collision that was the equivalent of a moving car hitting a stationary vehicle at five to 10mph. He used the term "equivalent barrier speed" and the judge, Mr Justice Saini, has interrupted him to ask him not to use that term. He said: "Just try to explain to us in lay language what is going on."
The prosecution case against the eight defendants is continuing
