Then how come they aren't beating Redbull and Toro-Rosso? Everyone knows Mclaren has the best chassis on the grid.
Because Mclaren do not have the best chassis on the grid. They have a mid field chassis and a mid field PU.

Top speed is controlled by BHP and Drag only.
Max speeds at finish line in Qualy today:
1. BOT 366.1
2. VES 354.2
3. ROS 351.2
4. HAR 350.8
5. HAM 350.8
6. GUT 350.7
7. PER 349.4
8. BUT 349.1
9. KVY 348.9
10. PAL 347.8
21. ALO 339.5
Generally theres a group of cars around 350kph and a second group at around 340kph. I would assume that this represents a split in strategy between drag levels but I havent looked into it. What we don't see is the 2 honda powered cars hanging out of the bottom so either Mclaren have a very low drag car (appears unlikely from wing levels) or their PU is in the ballpark.
Now if we look at the speed trap figures (210m after turn 20) we get somewhat different figures
1. ROS 334.8
2. HAM 333.6
3. HAR 333.2
4. BOT 333.2
5. PER 331.8
6. VES 331.1
7. ERI 330.3
8. GUT 327.7
9. RIC 326.6
10. RAI 326.0
20. BUT 322.8
22. ALO 319.3
At this point we really do see both the Honda cars hanging out of the bottom. From watching the onboards its clear that most of the cars were practically hitting vmax today due to the length of the straight. There was very little acceleration between the start finish and T1. So to put into words what the data is clearly telling us...
Mclaren Honda were quite noticeably slower after a series of high speed corners than the vast majority of the field but they were still able to reach pretty much the same Vmax. Potentially Mclaren Honda could be exiting T20 with an extra 10kmh, this might have got them a little bit faster over the start/finish it might not, I couldn't say.
The only way this data could possibly support a view that the Honda PU is the problem is if we could demonstrate that Mclaren are running much less drag / downforce than their rivals. Which from previously shown wing levels looks unlikely.
Interestingly the speed trap is before the DRS activation. Now im going to take a decent sized logic leap here and assume that each driver set their best speed trap and best speed across the start finish on the same lap. Which gives us an interesting comparison.
1. BOT +32.9
2. VES +23.1
3. ROS +16.4
4. HAR +17.6
5. HAM +17.2
6. GUT +23.0
7. PER +17.6
8. BUT +26.3
9. KVY +24.0
10. PAL +24.8
21. ALO +20.2
Now we know that BOT got an amazing tow for his top speed however there is a clear split between gaining ~17kmh with DRS or gaining ~24kmh. Again im going to go out on a limb a bit here and suggest that this split differentiates those with a large, high downforce rear wing, and those with a skinny wing. A larger wing when opened for DRS will reduce the overall drag by more than opening DRS on a smaller wing. This appears to suggest that Mclaren are also running a pretty heavy wing level compared to those around them.
I don't think it shows which drivers got a tow as overall their vmax are all very similar and I would expect those with the tow to be grouped at the top.
Taken together this all suggests that Mclaren are running a higher drag package than most of their competitors and that this high drag level is getting them less efficient downforce than those around them. Therefore lower performance in high speed corners and slightly lower top speeds and getting a larger benefit from DRS than most of the field.
