Grab an issue of a car magazine (like Car & Driver) with a review of one of the cars and that’ll tell you for certain, but I’m 99% positive that the engines are the same. The differences in the two engines would be entirely in the electronic controls. IIRC, the Ford Contour and one of the new Jags are the same car, with the Jag getting different trim, options, interior and price tag than the Ford.
