Nov 8 (Reuters) - George Russell's engine-related retirement from last Sunday's Sao Paulo Grand Prix will have no knock-on effects for the last two races of the Formula One season, Mercedes said in a team debrief on Wednesday. The Briton was retired at Interlagos as a precaution after rising temperatures in the power unit risked failure and wider damage to the car. Mercedes head of trackside performance Riccardo Musconi said Russell was always scheduled to have a different power unit for Las Vegas and the Abu Dhabi season-ender. "He will be on a different power unit for the final two races so there is no issue from that point of view." Musconi said Hamilton's disqualification from second place in last month's U.S. Grand Prix in Austin for excessive wear of the under-car plank might have contributed to the lack of pace, without being the determining factor.
