Firstly the 2 Autocar tests you refer to happened on different days where wind was a factor, the h2h showed the P1 to be way faster once rolling.Firstly, according to Auto car's test, acceleration data are pretty much identical for 918 WSP and P1. 918 is just 0.2 second slower than P1 when speed reaches 180 mph. For any other comparisons like speedometer or synthetic images are totally in different environments which doesn't make any sense for comparison.
Secondly, same time to reach same speed doesn't means running the same distance in case you have any experience on drag race in person.
At last, which is more important is to get better drag performance, P1 must be transformed to non-track mode which would be never used on tracks to compete with 918. And also, the peak speed on track is another thing we cannot directly refer to drag data, cos we need to take cornering speed and out-corner speed into account. So far, there's few evidence we can find out to prove any one of them has absolutely higher top speed on same track. Top gear Spanish test reveals us that 918 got higher peak speed than p1. The result from MotorTrend's test between GT-R NISMO and Corvette Z06 makes me believe 918's monster torque, zero-lag engine and traction benefit from AWD system would have no reason to make itself at a disadvantage comparing with P1.
The C&D and MT results also showed the P1 about 1s faster from 60-150mph.
Normally I would agree with you and speedos but the McLaren speedometers are very accurate unlike Lamborghini ones and given the PWR advantage Ferrari claim the LaF should leave it for dead, i.e. we shouldn't need to discuss technicalities.
Well aware of drag race phenomena, so let's be clear about this, the P1 has measured 9.8@149mph compared to a quoted 9.8@152mph. The LaF is quoted at 9.5@157mph and won't get anywhere near that time or speed.
For a quarter mile Race mode vs Track doesn't make much difference. TGs peak speeds for the Spanish test were transposed, you can tell by the cornering g figures.
Heh, the Z06 suffers massive drag from a badly designed aero system with very high drag/downforce ratio and also suffers bad heat soak. It was also a manual in the MT test.
