Same lock, different lengths. There's the standard 230mm length version, and the 300mm version. Sometimes retailers and reviewers either included the 54 in the title or left it out. At the time, whether they called it the ABUS Granit-X Plus or the ABUS Granit-X Plus 54, it was still the lock called the 54/160 in the ABUS catalogue. I would guess that they used different tools in the second test, or the lock's metal has had more hardening than the previous model. Now though there does need to be some differentiation in what the locks are called, as even the Bordo has a Granit-X Plus model, and its from a different range.
I'm also sceptical about the second lock test from 2010, as it appears that it would make the Granit-X Plus 54 to be an even stronger lock to break through, than their own monster ABUS Granit Extreme 59, and I am 100% positive that is not true. Even if it had been improved, it wouldn't have been improved that much.
