Nothing new and nothing to worry about. They did a film day today and no failures were reported by anybody. It's just the same story over and over again but with different headlines.
Taking apart a engine doesn't take a slong as every article says, they already know what the problem is and from my perspective it seems like a "one of the first engines, onetime failure" problem. The engines ran thousands of kilometers on the dyno. Also, there were NO signs of a mechanical failure during the test, so turbocharger and ICE should still be alive. Maybe it's just a way to hide what the have, who knows.
Besides that: Goddamn, the new engine sounds raspy as hell and I love that soo much. Obviously they seem to use less cylinder shutdown (at least in test PU-strategy) but that makes the "switch to cylinder-shutoff sound" even sweeter.
That Twitter post when Vandoorne halted for a pit stop though (listen at 0:06 for that Switch *.*)
