The time when a Formula 1 team would design its car, bolt an engine in the back, fill it up with fuel and head off testing to see if it had built a diamond or a dud is long gone.
Indeed, the arrival of the turbo hybrid era sealed the fact that getting ahead in F1 was all about packaging the car and engine together. Only by developing them in tandem could a team really hope to achieve success.
The V6 power unit itself was a harmony development story too, because in a bid to get the most out of the original 100 litres per race fuel limit, the oil and petrol being used needed to fit it perfectly. These two elements had to progress together.
