Pirelli chief Paul Hembery says the wider 2017 Formula One cars would be impossible for "a normal human being" to drive due to the huge G-forces involved.
Pirelli's chunkier tyres are a big part of the new regulations which have come into play this year, which were aimed at making Formula One cars more physically demanding for its drivers, with higher levels of downforce dramatically increasing cornering speeds. The Italian manufacturer promised a five-second drop in lap times compared to 2015 -- something Mercedes' Valtteri Bottas achieved on the third day of pre-season.
The early indications from pre-season are that corners such as Barcelona's 280 km/h Turn 3 can be taken flat out, something Hembery thinks highlights the huge demands of F1's new generation of car.
