Kimi or Andrea? Antonelli answers with his speed

What's in a name? Mercedes Formula One team boss Toto Wolff has his own answer when it comes to addressing 18-year-old rookie Andrea Kimi Antonelli.

Is the Italian, who has taken the seat vacated by seven-times world champion Lewis Hamilton, an Andrea or a Kimi? Or both?

Antonelli is relaxed about it. For Wolff, it is a matter of performance.

"Kimi, you're not an Andrea today," the Austrian declared over the team radio as Antonelli took pole position for the Miami Grand Prix sprint last Friday, becoming the youngest ever F1 driver on a pole of any sort.

Kimi, a name familiar to any F1 fan from Ferrari's 2007 world champion Kimi Raikkonen (although Antonelli was not named after the Finn), sounds racy and has become quickly adopted by commentators.

Andrea is the name for friends and family. It is also the one Wolff uses as a joke between them according to team insiders when things could have gone better.
