Formula 1 achieved a quite incredible feat last year, one that was disgracefully overlooked in most quarters, sometimes by those purporting to enjoy the technology in grand prix racing.
Last year, every car had to complete a grand prix distance, from lights out to chequered flag, on just 100kg of fuel. Staggeringly, it wasn't long before some were actually short-fuelling in order to save weight, without paying much of a performance penalty.
Think about that for moment. Really think about it. That's a reduction of about one-third of the fuel in one leap. Truly astonishing.
