I went to testing in Jerez this year and then to Barcelona a couple of weeks back. I am conflicted on the new engines.
Firstly, they’re pretty much unchanged from testing in Jerez to now. They’re certainly using more of the engine range now but they sound the same and they’re no louder than before.
Looking back at the V8 era, I went to the last Istanbual grand prix a few years back. I took my fiancee and it was her first experience of F1. Getting off the bus about 1 km from the circuit during the middle of FP1, her eyes widened at the sound of the engines (even though it was a wet track). We walked up behind the main grandstand, the noise grew, and her reaction was amazing. Then, going trackside, she had the full V8 experience. The V8s were intimidating – you don’t hear them, you feel them, using more than one sense. The noise and sheer demonstration of power is awe-inspiring. You’re left with no doubt that you’re at a serious motorsport event. However, by the Sunday and 5 laps into the race, we were both reaching for the ear plugs – it just gets too much.
Fast forward to Jerez testing and things were very different. We parked up less than 200 metres away from circuit entrance B and it was silent. Getting to the gates and we could hear something. Onto the track and, as others have said, you can stand just metres away, and the experience is very different. The V6 noise is rich, but they clearly don’t have the same engine rev range and there’s no wall of noise. You do get to hear other interesting mechanical sounds though.
Moving on to Barcelona, and the noise was the same as Jerez. Completely bearable with the whole grid going past at once (we were at turn 1). You can hear the turbo spinning under power and under breaking, and the mechanical sounds of gear changes are now audible. As others have observed, you can hear the tyres squeal too, and when the drivers run over the kerbs (Ricciardo was the only driver in Barcelona to consistently run wide onto the kerb before entering turn 1) you can hear the buzz of the vibration.
Early on in the Barcelona race weekend, I made my mind up that I preferred the new V6 sounds. Interesting noises, loud for sure but not deafening, and a good note although it would be nice if they revved higher. However, then a support race came on (I forget which, but using V8s). They were louder, revved more, and suddenly it felt like the F1 cars that had just left the track no longer represented the pinnacle of motorsport. Suddenly they seemed rather underwhelming, to the point where I really struggle to make my mind on what I prefer.
My final observation is that the V6 engines and exhaust produce a very one-directional sound. If you’re not facing the exhaust, they’re pretty much silent. On the V8s, it didn’t matter where you were – they were just loud.
If pushed to choose I would take the V6s. There are plus points for race days, notably that you can hold a conversation at the track during the race rather than sit there dumbly for 2 hours with ear plugs in. But I miss feeling the sound of the power as well as hearing it.
