Bortoleto set for back of grid after 20-place Austin penalty

Gabriel Bortoleto faces a 20-place grid penalty for Sunday's United States Grand Prix, putting the Audi driver at the back of the grid. Arvid Lindblad faces a five-place penalty and Franco Colapinto a 10-place one. The three sanctions were known just after first practice in Austin, with all three using power-unit components outside the permitted pool.

Bortoleto is using a completely new power unit this weekend. His internal-combustion engine, turbo and exhaust remain within the permitted pool, but the energy store and control electronics do not: he is using a fourth of each, although only three are allowed. Each component brings a 10-place penalty.

Racing Bulls opted to fit a sixth internal-combustion engine to Lindblad's car. Four are allowed per season without a penalty; because this is the second component outside the pool, his penalty is five places rather than 10.

Colapinto has a 10-place penalty for using a fourth control-electronics unit, the first beyond the permitted allocation.
