Yes and no. You can build a car that is optimized for one thing or another easier than one that does it all. To build a killer cornering car, you really want a 4 wheel independent suspension, while it is easier to have a live axle rear in a drag car for strength reasons. Now you could build a road race themed car that runs 10's, but it would take more power than a pure drag car to hit the number because the suspension is optimized differently. A drag car should have a fairly loose front suspension with 90/10 shocks, no front sway bar, loose front springs, etc., none of which is good for anything but a straight line. A salt flats car benefits from slow initial acceleration due to very tall gears of around 2.4:1 vs the drag car's 4.10's, plus they work best with narrow, hard tires to reduce drag. Narrow, hard tires only work on the flats, not on corners or a drag strip. Also, narrower cars (with respect to length) are better on the flats, but horrible for handling corners. You can see how this goes. Each type of racing requires different compromises to be competitive in their respective classes. While you could build a car to do it all, it would not necessarily be competitive because it would not conform to any one class.
