No issues at all at high speed, directional stability is superb and on par with other supercars ( I can compare to Ferrari, Mclaren, Corvette). The car has just a tendency to understeer in hard driven corners. One night I had a Huracan Spyder in front of me. He moved to the right lane as he could not leave the Lotus behind till about 250kmh. I dont think the 311 has a disadvantage though . I noticed that the car starts to shake at about 260-270kmh when the driving surface is not perfect clean. Small bumps and the car will start to splutter. The optional öhlins suspension has still the factor
