The Williams FW42 was late, off the pace, and produced the worst season in the illustrious team's history in terms of deficit to the front.
Its sole point, courtesy of Robert Kubica's 10th place in July's German Grand Prix, came in a chaotic race after both Alfa Romeos were penalised. It was a disastrous year. As deputy team principal Claire Williams puts it: "It can't happen again."
Williams has certainly responded. The result was the departure of chief technical officer Paddy Lowe and a rigorous review that has led to widespread changes, including an improved system to track the design and manufacturing of all components.
