Not really that much of an expert here, but here goes. This is what saw and heard at the first corner...not that I rememberd every detail whilst being so excited to attend al live F1 event for the first time.
Mercedes: Class act, I have to admit. Mid corner and exit stability was just perfect. Not even the sausage kerb at the exit disturbed the chassis as it simply absorbed any impact and carried on powering along the hill. Exit speed also very impressive as the car disappeared.
Ferrari: In the hands of Gutierrez, I'd say the car was not used to it's full potential. No sudden moves mid corner and almost Mercedes like chassis behaviour on the sausage kerb. I must also add that it actually does sound every so slightly different to Merc. It's something that you pick up after paying attention to them for longer. On first sight, can't separate them sound wise.
Williams: Composed and nice, but as Bottas once powered behind Nico up to turn one, both had zero drama but somehow Nico pulled away for a meter or two easily. Can't say why, not gonna play a smartass.
Lotus: Seemed to me they were mostly on long runs and evaluating race pace. Quite some corrective action at the exit, but that might also be a car more sensitive to the lower temps.
Red Bull: This one was interesting. A lot of sounds that reminded me of the EBD effect in 2012. Off throttle and downshifting "farts". Ricciardo was also the only one that attacked turn one very differently. Whilst everyone was going through half throttle or off throttle, young Ric stamped on the gas 100% very much mid corner and took every last centimeter of the corner exit. And the car enabled him to do it. My guess is that part of that is his driving style and in part Renaults slightly lower power, enabling him to floor it without much consequences.
Toro Rosso: Very similar to RBR, but quite a lot of correcting at the exit without Ricciardos tactic of stamping the throttle early. A different test programme maybe or just a rough diamond of a chassis.
Sauber: Only thing I could gather is that the customer Ferrari engine is not factory team spec. A bhp or two down.
Force India: They were evaluating so many combinatons of nose, aero equipment that I really don't know how to judge the car. Seemed to put it's power down very nicely though.
Mclaren: Oh my...every outlap it made some new noises and everytime they were nasty. Farting, cracking, rumbling, you name it. At one point Alonso was in the groove and it handled pretty nicely. A clear demonstration of power was seen when Nico was ahead before the first corner and then just left poor Alonso for dead at the exit.
All in all I'd say that Force India will progress with these parts and testing, as should RBR. Mercedes are out there doing their thing, bless them. Ferrari was secretive as f---, wouldn't even open the garage during the pitwalk, Williams is right with them IMO, Toro Rosso and Sauber kinda in their own world and Mclaren...well, they're trying. That's the nicest thing I can say.
Also...the sound? I expected much less and I am not that disappointed. It struck me that they produce a nice tone from the V6 and all those turbo sounds do make for a bit of spectacle. But on the other hand, I listened to hillclimb prototypes and F3 cars a couple of days ago at a hillclimb event. As a marshall, I stood a couple of meters away from them. Those screamed for a mile away and shook my internal organs to hell. The F1 V6 hybrid? Went off the main grandstand and stood behind it? More or less quiet. Stood in front of Merc garage and listened to revving? No gut wrenching to speak of. For F1 standards, very little punch in the face volume or menace. Take what you will from that...
Sorry for the long amateur post, but this is what I took from all of this. Great experience though, especially for such a low price.
