  We have discussed here a higher dimensional cosmological model and explained
the recent acceleration with a Chaplygin type of gas. Dimensional reduction is
possible in this case. Our solutions are general in nature because all the well
known results of 4D Chaplygin driven cosmology are recovered when $d = 0$. We
have drawn the best fit graph using the data obtained by the differential age
method (CC) and it is seen that the graph favours only one extra dimension.
That means the Chaplygin gas is apparently dominated by a 5D world. One may
point out that the resulting field equation is highly nonlinear in the scale
factor. Using this equation both dust dominated and accelerating universe are
explained as extremal cases only. But to our knowledge we have not as yet come
across any explicit solution of scale factor as function of time. To avoid such
incompleteness, we have taken the first order approximation of the key equation
and subsequently have found out the time explicit exact solutions of scale
factor. This solution approaches $\Lambda$CDM model for large scale factor and
the desirable feature of acceleration flip occurs in this case. We have also
made a detailed analysis of flip time both analytically and graphically.
