    • ‘When a risk is present the dynamic stability and traction control anti-skid system is activated and responds by reducing engine power while braking one or more wheels until the car understeers and stability is regained.’
    • ‘At speed, this reduces to concerns about whether the car drives too ‘tight’ or too ‘loose’ - tight meaning it is hard to turn, it understeers, and loose meaning it turns too much, it oversteers.’

    • ‘Once you get over the first initial shock, it proved easy to use, though there was noticeable understeer if you enter the corner carrying too much speed.’
    • ‘In fact the only times I ever got understeer were when trying to induce power oversteer, which of course effectively means using too much throttle for the turn.’
    • ‘The softish suspension and noticeable understeer produces a nice comfortable drive.’
    • ‘The cars are configured for mild understeer, although you can turn that into oversteer quite easily if you twitch your toe in the middle of a corner.’
    • ‘When we write about new cars and trucks, we try to bring out the engineering aspects of the vehicle, not about whether there is a silky smooth shift pattern or whether the vehicle exhibits too much understeer.’
    • ‘When you do push it beyond the limit of grip into a sweeping bend or large roundabout the front end drifts wide, revealing that the chassis is biased towards mild understeer.’

    • ‘More of a concern is that, with the traction control on, the car suffers from disastrous understeer.’

    • ‘To quell understeer, for example, the system slows the inside rear wheel slightly in order to pull the nose back toward the inside of a turn.’
    • ‘This is an active safety feature designed to help prevent accidents by registering and helping to correct oversteer, understeer and loss of stability in the vehicle.’
    • ‘The suspension makes short work of potholes while the positive steering gives a hint of understeer.’
    • ‘The system controller can then make the necessary adjustments (e.g., induce understeer in cases where there could be wheel lift) to minimize the states that could lead to roll over.’
    • ‘It was okay, but I was struggling with severe understeer, so we tried some different set-ups during the afternoon.’
    • ‘It was a fine demonstration that taking a car by the scruff of the neck doesn't have to mean ten minutes of lurching, understeer and oversteer.’

    • ‘The consequent loss of grip invariably causes understeer that the drivers must contend with.’
