Mercedes explains Mexico City's high-altitude setup challenge

Mercedes says altitude is a key setup factor for this weekend's Mexico City Grand Prix: the Autódromo Hermanos Rodríguez sits more than 2,200 metres above sea level, where thinner air affects both teams and cars.

The conditions affect parts of Mercedes' W17, including the turbo, while teams often use slimmer rear wings to reduce drag on the long main straight, the team says.

Mercedes says the low air density keeps drag minimal and cars often reach top speeds on the straight. It adds that a Monaco-style aero package is better suited than the similar setup some might expect at Monza.
