Lotus unable to run Double DRS at Spa
1 September 2012 – Lotus has shelved its innovative 'Double DRS' for this weekend’s Belgian Grand Prix, having been unable to properly test the concept as Friday practice was washed out.
Romain Grosjean and Kimi Räikkönen in particular had been tipped by many for victory, both in Belgian and in Italy, as the tool – already trialled in Germany and Hungary and dubbed inside the team as ‘The Device’ – would have yielded huge straight-line speed advantages. Despite its absence, the E20 chassis is still expected to be rapid at Spa.
The Lotus system does not function like the Mercedes ‘Super DRS’ which caused so many headlines earlier in the campaign. Whereas the silver arrows’ idea requires DRS to be in use and feeds extra airflow to the front wing, the Lotus version operates regardless of whether the rear wing slot gap is open or not.
It effectively functions more like the f-duct which was innovated by McLaren two years ago, but does not require driver activation which would make it illegal under revised regulations.
