Kimi Antonelli kicked off the Austrian Grand Prix weekend by topping first practice, edging out teammate George Russell by just 0.04 seconds. The Italian's strong start put Mercedes in control ahead of qualifying, with Oscar Piastri's McLaren closing to within 0.117 seconds of the pace in third place.

Seven-time champion Lewis Hamilton struggled with his upgraded Ferrari power unit, trailing by 0.665 seconds and appearing dissatisfied during his limited running. Ferrari insists the engine package introduced in Austria won't bridge the gap to Mercedes, despite the circuit favoring power units and potentially masking aerodynamic gains. The team faces questions about whether they can sustain their early-season challenge.

Max Verstappen ran a major aerodynamic upgrade on his Red Bull but could only manage fourth place, 0.281 seconds back. Lando Norris lost most of the session to a hydraulics problem, finishing seventh. McLaren opted not to deploy a new rear wing design after deciding it needed more work, potentially costing them valuable development mileage.

Antonelli's crisp opening session sets up an intriguing qualifying battle between the factory teams, while Hamilton's frustration signals Ferrari may need further development to remain competitive.
