Hartley at back of grid, rain halts practice in France

Toro Rosso's New Zealand driver Brendon Hartley penalised over new engine parts

Brendon Hartley will start Sunday's French Grand Prix from the back of the grid after being handed a 35-place penalty on Saturday for taking a range of new engine parts.

The under-pressure New Zealander had to stop his Honda-powered Toro Rosso car in the closing minutes of Friday?s second free practice session.

Honda on Saturday confirmed it fitted a new internal combustion engine, MGU-H, turbocharger, MGU-K, control electronics and energy store to his car, taking Hartley beyond his permitted limit.

Hartley was back in action on Saturday in a brief spell before heavy rainstorms hit the Le Castellet circuit bringing third free practice to a halt.

Swede Marcus Ericsson was also back in the fray after the scrutineers passed his replacement Sauber car as safe to run following his fiery crash on Friday.
