Man, tough crowd...
So the sound needs some work, but honestly when you consider the technology that these cars are running, doesn't that at least spark some interest? Yes they're quieter, but all that wasted energy from the exhaust is being recovered for more horsepower. I'd rather have more power than sound.
I'm an N/A engine guy, always have been, and always will be. My roommate likes turbos, I don't, but the tech on these cars definitely sparks the engineer in me. This is the direction motorsports is going, because this is the direction society and the consumer automotive market is going, plain and simple. small displacement turbocharged engines using some sort of energy recovery system will be what most of us will be purchasing in the next 10 years I bet.
I'm not an advocate for racing having to be relevant to road cars, especially monoposto racing, but the tech here is really, really neat. close to 900 HP on full discharge out of a 1.6L v6. That's about 200 more HP than the old 3.0L ferrari V12 engines of yesteryear. Tell that me that isn't impressive?
All this being said, I think engine rules should go back to the way they were in 1969, and wings should be eliminated.
