They're not designed to be loud that's the
problem, As with most turbo car's they're not as noisy as a tuned NA motor
I was sceptical about them being introduced over the V10's and more recent V8's but they seem to be a little unpredictable and with reliability being an issue for most teams it should make the racing more competitive and less predictable
The fact that there's more power than grip also makes life interesting, I'm looking forward to watching people lose it on tight hairpins (Monaco etc) due to the car's having so much torque even in the higher gears
