To get those noises (they call them pops and bangs
) on mine, sport mode has to be on and the engine needs to be warm. I read somewhere that in sport mode, it injects a tiny bit of fuel in on overun to get effect.
Maybe it needs to be run in before it goes bananas?
I've had some fast road bikes (bmw) that are slightly restricted until first service and running in are complete
You picked a great car for fun factor - I've had MUCH faster and more powerful (read pricey) cars in the past that were nowhere near as much fun. The miini feels fast even when driven normally.
My next one will be the John Cooper Works model with a "manic motors" remap - vrrrroooooom ...
