Penalties for Hülkenberg, Vandoorne, Hartley
20 October 2017 – Renault's Nico Hülkenberg, McLaren's Stoffel Vandoorne and Toro Rosso's Brendon Hartley will all take power unit-related grid penalties at the United States Grand Prix.
Under current regulations, drivers are permitted to use only four of each of the six elements that make up the power unit before grid penalties are imposed.
The first time a fifth element is used, a 10-place grid penalty will be imposed, with a five-place drop issued the first time a fifth of any of the remaining elements is used.
The first time a sixth element is used, a 10-place grid penalty will be imposed, and so on.
Hülkenberg took on a sixth MGU-H, fifth ICE and fifth Turbocharger ahead of Friday practice at the Circuit of the Americas, resulting in a 20-place drop.
Hartley, making his Formula 1 debut with Toro Rosso, will run a sixth ICE, sixth MGU-H, fifth Energy Store and fifth Control Electronics, which totals a 25-place penalty.
Hartley is running Toro Rosso's #1 chassis, previously raced by Daniil Kvyat and Pierre Gasly, with Kvyat now on the #2 chassis, formerly used by Carlos Sainz Jr.
Vandoorne, meanwhile, has moved onto his eighth ICE, featuring "small updates" from Honda, which has labelled the unit 'Spec 3.8', leading to a five-place drop.
Red Bull's Max Verstappen has also taken on a fourth Energy Store and fourth Control Electronics, and is expected to exceed his engine allocation on Saturday.
