The answer is 570 litres seats - up (a ten - litre improvement on the old model) and 1700 litres with the seats folded flat, a 30 - litre bump over the old car.
No one's going to mistake the NX for a sports sedan, but the performance reminds me of the old Acura RDX Turbo, yet without that car's sometimes skittishly rough ride over mid-corner bumps.
