What is quite telling is that Kimi and Mark set their laps at just over half distance when the cars were still quite heavy.
Alonso has a great car but if the Renault powered cars keep putting in these sorts of performances, then his lead isn't unassailiable.
Race pace laptimes dont really tell us what the 'fastest' car is, ie; Im sure Lewis could have given us a fastest laptime if he really had to... at the unwanted expense of reduced tyre performance later in the race. F1 races are now pretty much endurance events as far as the current tyres go.... and yep, the fact that Kimi and Mark set their fast laps at just over half race distance says it all.
