As a motor racing fan, I'd like to have naturally aspirated engines of at least eight cylinders and at least a displacement of three liters. For the sound and the tradition and their relative simplicity. But then, the left side of my brain tells me it's a technology of the past and those engines will never come back. Very sad..., but true. For the sake of efficiency, future is hybrid and turbocharged, like it or not. It's the price motorsport has to pay for being accepted by environmentalists.
I'm not saying it should stick its fingers up at environmental consideration with the following, it's a good point there and it has to be included. Equally though, it shouldn't allow it to dominate every aspect of its future even to its detriment and it shouldn't be scared to have the debate and fight its corner.
Surely the argument against needs to be to look at the carbon footprint a sport leaves overall if you want to argue about its environmental impact? Think of football and all the flights that happen all over the world, week in week out as teams travel to fixtures. Arsenal (London) flew to Norwich for an away game a year or so ago!
The argument quickly boils down to symbolisim for the manufacturers and campaigners.
I hear cosworth are interested in the new engine formula!
