Sebastian Vettel (Retired, Lap 6): 5.5/10
Ferrari headed into this weekend's race fearing a repeat of last week's dismal performance at Spa. While it wasn't quite that bad, the outcome was if anything even worse, and certainly more embarrassing given that it was at their home race. Sebastian Vettel was second slowest in Friday morning practice, wedged between two Williams on the timesheets, and so it wasn't a huge surprise when he failed to progress beyond Q1 the following day. The race had barely started when he started to experience some troubling issues with his brakes, and it was just six laps in when the problem went from troublingly chronic to devastatingly acute. The rear brake disc exploded as Vettel approached the first chicane, and the Ferrari ploughed through several polystyrene marker boards before limping back to pit lane. There's not much comfort that either Vettel or Ferrari can take from this.
Kevin Magnussen (Retired, Lap 17): 6/10
The two Haas drivers were pretty evenly matched during practice, and it was a toss-up which of them would be able to make the cut at the end of the first round of qualifying. The honours went to Kevin Magnussen over Romain Grosjean by a couple of tenths, but it was all for nought once the race started. Magnussen got tangled up in a three-wide situation heading into the first turn and he was forced to pit for repairs and a new front wing. That put him trailing far behind the rest of the field, but he slogged on for another 17 laps and was pleasantly surprised to find the VF-20 showing good pace in all the clean air he was now running in. Sadly it only lasted for 17 laps before the car developed a bigger problem that forced him to park by the side of the track close to pit entry, triggering a safety car that would change the course of the race. Not that any of that affected Magnussen himself, who was already heading back to his trailer.
