If you are into muscle cars, chances are you love racing (or watching races) on a drag strip. Most folks who hang out at the drag strip will tell you that you will need some heat in your tyres to get the tyres to hook up better. So Ford came up with its latest feature, the 'electronic line-lock' to assist the driver in doing burnouts.
You may think that burnouts are easy to do but modulating the brakes while letting the driven wheels spin up on the spot is tougher than you imagine (in manual transmission of course). But with Ford Mustang GT's line-lock, all you need to do is to throttle hard. The car will apply brakes on the front wheels only while the rear tyres are free to spin.

For those who still like to DIY, you will be glad that this assist can be turned off.
