Found out what "Lifting" means, the hard way at Blackhawk Farms Raceway

Trailing throttle oversteer can happen in any powered, wheel driven vehicle that sends power (or even the majority of power) through the rear wheels. Depending on the vehicle and a myriad of other factors from weight to balance to suspension tuning, gearing, drivetrain configuration and tire selection, it will take more or less to provoke a tail-out orientation; but push the limits of your particular combination and it will happen.

The net effect is similar to pulling up your hand brake at speed while turning, or grabbing the rear brakes on your bicycle while your handlebar is turned.

The phenomenon is not necessarily your enemy if you master your car's dynamics and use it deliberately and judiciously.

Edit - re the Lotus: 1500KG is way heavier than most Cobras - surely it was lighter than that?

Also, rear or rear/mid engined cars generally tend to have more weight aft of the centerline and they will really swing their tails out when the rear tires lose grip in a corner. Some are better balanced than others, but cars like the old Porsche 930 Turbos were extreme in that regard and they will swing their arse end around like a pendulum.

Buzz, yep you are right, I mispoke, the Lotus was mid engine and turbo charged, behind the driver anyway, thus my "rear engine" comment and had a curb weight of 1,800 Pounds (818 Kilograms) I guess I was thinking of pounds but wrote kg. mea culpa. tin-man
