According to Renault F1 chief designer Pat Symonds, ground-effects aerodynamics and turbocharging, both of which were banned in the 1980s, could return.
Writing in F1 Racing magazine, Symonds sees the 2020 F1 car also having low-profile tyres on bigger wheels, Kinetic Energy Recovery Systems (KERS) that produce 185kW and a standard, non-downforce rear wing.
His vision of a future F1 car takes into account the likelihood of future rules on fuel consumption and CO2 emissions.
F1 teams have already been instructed to reduce fuel consumption by 35 per cent, while a more environmentally-friendly 1.6-litre turbo engine will be introduced in 2013.
"Taking into consideration all the variant motivators that drive regulations, I expect that the F1 car of 2020 will demonstrate much more change than has been seen over the past 10 years," he says.
