BMW holds, from time to time, driving events featuring their products and competitors’ product for comparison. This year it is the Un4gettable Test Drive, featuring the BMW 4 series coupe. Coming along for the party were, amongst others, a Cadillac CTS and a Mercedes-Benz C350. All three of these sporting coupes are available in rear wheel drive or all wheel drive.

On paper there is enough equivalence to make the comparison of the three interesting. One caveat before beginning however, the Cadillac CTS is aimed more towards the 5 series, E-Class as a competitor, not towards the 4 or C-Class. The Cadillac has a longer wheelbase and is half a foot plus longer than either the C350 or 435i. But, importantly, pricing is similar for the three.
