Guys HUGE Problem on my Jaguar X type, please help me

The car's been running quite smoothly for the past few days and now when I start the car there's a huge amount of smoke coming out without stopping and when I accelerate, the car responds by revving but it does not move forward most of the time. When it does move forward, it moves very slowly and I need to fix this in a hurry. Any help appreciated

my initial thought would be, it sounds like you have lost compression, which makes me think you're head gasket has gone, and your burning oil

are you a member of the AA / RAC or the like? if so, get them out to have a look 

Good luck

Welcome to the Club, Yashen.

What colour is the smoke, as that will be a clue?  What engine does your car have, diesel or petrol?.

To check out Steve's suggestion, have a look in your coolant reservoir and see if there are traces of oil.

It is also possible that it could be a clutch problem.

Certainly, the first thing I would do is call out your breakdown service.

Regards, Peter.
