DRIVERS are only just realising which cars have a hidden button that can save you time - but comes with a serious risk.
Some models of Mitsubishi, BMW and Volkswagens have the secret switch, as well as some Porsche and Alfa Romeo.
The button in question is launch control - which helps motorists zoom off faster than just putting their foot to the floor.
But, car enthusiasts have warned it can be dangerous.

But others were all for the mode.
One person wrote: "It definitely is much quicker than just planting your foot down.
"I've done it twice on mine and it makes my head go funny."
Another who trialled the mode when they worked for VW said: "It was definitely quicker and certainly a big difference."
However, they added: "If I owned one, would I do it?
"Yes - but I guarantee I wouldn't do it many times."
