Just how impressive was Nico Hulkenberg?
Sebastian Vettel may have enjoyed another peerless weekend at the front in Korea, but there was little dispute that one of the grid's other highly-rated Germans, Nico Hulkenberg, produced the standout performance of the race by finishing fourth. Although Sauber, thanks to some judicious improvements to the C32 and the change in Pirelli tyres, have clearly moved several steps on from their surprisingly wretched early-season form, their car is still clearly not quicker than either a Mercedes or Ferrari. Yet Hulkenberg nevertheless finished ahead of both Lewis Hamilton and Fernando Alonso.

His ability to withstand sustained pressure from Hamilton during their run to the flag after the second Safety Car period was particularly impressive given, on a day when most of the field were struggling with right-front graining, Hulkenberg completed a final stint on the medium tyres of 29 laps. To put that into context, the German ran two laps longer than Alonso, three more than chief pursuer Hamilton and five more than race winner Vettel. Indeed, of the top seven cars, only Kimi Raikkonen with 30 laps ran on the white-banded rubber for longer.

Having been told by his race engineer that the right-front on his previous set of tyres, which he had completed the opening ten laps on, had been "at the end of their life" when removed from the car, Hulkenberg had cause for concern that his latest mediums wouldn't last the distance and duly said over the radio "I just hope we just don't fall off like bananas at the end of the race".

The resultant instruction was to look after the rubber as best he could, but with Hamilton constantly on his gearbox - even briefly overtaking the Sauber into turn one on lap 48 - Hulkenberg couldn't afford to rest on his laurels as he made numerous defensive moves to keep the marauding Mercedes at bay. By the end of the race he was lapping up to two seconds slower than Vettel, but Hamilton was still behind him. That Hulkenberg achieved it in the face of such immense pressure, and without his tyres falling completely off the cliff, underlined the impressive scale of the German's performance.

Were Mercedes right not to pit Lewis Hamilton?
The increasingly exasperated nature of Lewis Hamilton's radio communications with the Mercedes pitwall in the lead up to his second pitstop in the Korean GP brought back memories of his miserable race in Spain in May. On that day, amid what was his uncontrollable slide down the order from the frontrow, Hamilton stated in matter-of-fact manner over the radio "now I've been overtaken by a Williams," after Pastor Maldonado demoted him yet another position.

While things weren't quite that bad on Sunday, such were the state of Hamilton's first set of medium tyres at half-distance that he was again lapping slower than both FW35s. From having been 5.6 seconds behind Sebastian Vettel at the end of lap 20, in the space of the following eight laps that gap had ballooned out to 26 seconds - at a rate of more than three seconds a lap. As a result, what had been Hamilton's 13-second advantage over team-mate Nico Rosberg was also wiped out, although the malfunction of the German's nosecone ultimately made that academic. But the massive laptime loss also meant that when he did eventually pit on lap 29, Hamilton had also lost out to the early-stopping Kimi Raikkonen.

So why then, with the W04 losing laptime and grip hand over fist, did Mercedes keep their increasingly agitated driver out on track for so long? Well, as Ross Brawn explained after the race: "An extra stop at lap 22 would have committed us to a much slower three-stop strategy, or we could leave Lewis in clean air to tough it out and try and reach the target lap to make our two-stop strategy work." It was a painful watch but in the cold light of day Hamilton himself admitted afterwards: "We couldn't have done thirty-five laps on the tyres."

However, Mercedes did suffer a rather unfortunate additional slice of bad luck as they executed this strategy. As the radio message delivered to Hamilton on lap 29 implied, Mercedes would have called the Briton into the pitlane at the end of the previous lap had Rosberg's sparking car not required more urgent attention. That extra 5.6km tour, and the resultant loss of several more seconds, meant Hamilton ultimately exited his pitstop right behind, rather than just in front, of the flying Raikkonen, losing him his best chance of clinging onto a podium position.

Would Kimi Raikkonen have finished second without the Safety Car?
Somewhat amazingly, the Korean GP represented the fifth time in Kimi Raikkonen and Romain Grosjean's two seasons as team-mates at Lotus that the pair have finished second and third respectively on the podium - with all but one of those GPs being won by Sebastian Vettel, incidentally. The majority of those races have also followed a set pattern: Grosjean runs as the lead Lotus through the first half of the race only for his World Champion stable-mate, via superior speed or strategy or both, to eventually overhaul him for the runner-up position.

Sunday's race may have finished with that same two-three order but how it came about proved a different matter entirely. Having outqualified the sister car by six places on Saturday, Grosjean's advantage over Raikkonen on the track was 25 seconds when the Finn, at the time running in seventh place, made his second and final pitstop at the end of relatively early juncture of lap 25. Raikkonen's initial gains up the order on his return to the track were all hard-earned as a quick out-lap and then immediate new race fastest lap on his fresh medium rubber saw him jump four cars - Nico Hulkenberg, Fernando Alonso and the ailing Mercedes pair - when they all made their respective stops over the next couple of laps.

However, while now up to third, Raikkonen would have been able to do nothing about Grosjean had the first Safety Car not intervened on lap 31. With his team-mate's large advantage over him having therefore been completely wiped out, Raikkonen was perfectly placed to pounce on the sister Lotus's wide moment out of Turn 15 on lap 37 and nail him into the first corner on the next lap.

Grosjean's slightly superior pace thereafter underlined why he had been Lotus's lead runner all weekend but, as a wily old campaigner like Raikkonen knows only too well, you often make your own luck in this game and as the Frenchman himself ruefully reflected afterwards: "I should have avoided that Astroturf in turn 15 and it would have been the end of the conversation."

How perfect was Sebastian Vettel's weekend?
He may play down the significance of the records he continues to collect, but it's blindly obvious that Sebastian Vettel takes great pride - and satisfaction - from ticking off as many 'boxes' during a race weekend as he possibly can.

Indeed, for the second race weekend in a row - and the seventh time in his career - the World Champion chalked up the hat-trick of pole, win and fastest lap in Korea, making sure of the final leg of that on lap 53 of 55 when he banged in a 1:41.380 time which was six tenths of a second faster than his previous lap and half a second quicker than anyone else managed all race.

Even more impressive than that, however, was that Vettel added another even more coveted, and rare, 'Grand Chelem' to his collection by once again leading every lap in Yeongam. Given only 22 drivers in history have ever notched up this rather special race weekend quadruple, and only half of them more than once. So the fact that Vettel also managed it in Singapore really does underline Christian Horner's view that his driver is currently operating at an "unbelievable" performance level.

Vettel now has four such Grand Chelems to his name in his career (India 2011 and Japan 2012 being the others) which is already just one fewer than Michael Schumacher managed and half way to Jim Clark's overall record.
