Having recently travelled to south of France by Eurostar and TGV, I noted that high speed trains outside UK use articulated bogies (that is, instead of two bogies per coach, each bogie supports one end of two adjacent coaches). This reduces weight and cost, and in the event of derailment the train is less likely to jack-knife. Also, passengers are not sitting over a bogie so enjoy a better ride.
Why weren't Pendelinos designed the same way? Of course, it does mean train sets have to remain permanently coupled, but Pendos are anyway. On TGVs, the power cars have conventional bogies so they can be taken off the train for maintenance, but the coaches are usually left in permanent rakes so the articulation is not much a problem.
