I stumbled upon an ingenius solution while trawling another site!
All we need to do is genetically engineer horses to be heaps more powerful!
Actually, I think a 12 cylinder Internal GM Rodent engine (12 giant psychotic GM rats in treadmills) would be the refined persons choice. Complete with exhaust pipe to truck away those rodenty smells, and a little turbo impella to make sure those ratties get enough oxygen...
