Lotus set to drop DRD after Friday practice
23 August 2013 – Lotus is likely to abandon its Drag Reduction Device (DRD) for the remainder of this weekend's Belgian Grand Prix, following an inconclusive opening day of practice.
With light showers affecting the first 90-minute session at Spa-Francorchamps, the Enstone-based outfit had less time than desired to further develop the passive system, which channels airflow at high speed in an attempt to reduce drag.
And with the Friday evening cut-off point looming, Technical Director Nick Chester suggested that the device will not be granted its second race start of the season.
"We targeted it for Spa and we ran it through P1 and learned some more with it," Chester explained. "I don't think we are going to carry on with through this weekend because we didn't really get enough dry running to get what we wanted in P1."
Meanwhile, Sauber trialled its own passive system throughout Friday practice in Belgium, with the team due to hold meeting this evening to decide if it is race-ready.
"We tested some new aero parts and continued our test programme with our passive DRS system," said Tom McCullough, Head of Track Engineering. "This project is making progress and we will decide tonight wheather we will use it for the race."
