From the fifth photo and from the overall shape of the side windows, I'd say that is a 2+2. you can see the rear headreasts but it looks cramped in the rear. It generally looks shorter than the current Ark Royal. Maybe 32/42/GS length. The nose looks thinner in side profile so probably has the V6TT engine from the MC20. So we're looking at ~550+Bhp. Call me biased but the Stradale/2013-2018 nose looks best on the current GT and that looks largely similar but I'm not a fan of the boxy end scoops, too Germanic.
I think the bonnet lifts forward too. There seems to be a panel gap on the side wing and there's no panel gap line where you would expect it to be on the front shot. So would give better access to the engine.
