Lotus will have to make hasty modifications to the front suspension design on its E21 Grand Prix challenger ahead of next weekend’s German Grand Prix.
The FIA has instructed the Enstone-based team to redesign its front suspension layout, according to several reports from Silverstone, following a complaint made by McLaren to the sport’s governing body.
It is understood that McLaren’s complaint centres around the number of suspension components that can be connected together to make an upright, as is described in Article 10.5.2 of the Formula 1 Technical Regulations.
“The loads from the suspension members and wheel bearings must individually and entirely be carried by the suspension upright,” the rule reads.
“Exceptionally up to three suspension members may be connected together by titanium, aluminium alloy or steel components before their load is passed into the upright.”
According to media sources, Lotus’ front suspension design could be interpreted as having up to four members connected together, instead of the maximum three.
Following an investigation by the FIA, Lotus has agreed to modify its suspension design in time for next weekend’s Grand Prix at the Nurburgring.
