You've got that right! Where pure speed and high performance handling is concerned gas is the undisputed king. Remember VX fans, the raison d'etre for the VX was "torque on demand", not torque after it reacts to the load! Load handling driving is typically not concerned with performance cornering ability... there is no such spec at Caterpillar, its purely load reaction engineering for diesel success. Where diesels race its just a novelty, they are not setting any speed records on road courses. Believe me, if diesel was a viable road course option they would have tried in Formula 1 the pinnacle in motor sport a long time ago. Not even the Safety Car in Formula 1 is diesel, it would be deemed too dangerous to use such a load reaction vehicle in high speed pace work. Also, remember that the VX came equipped, stock, with license plate holders. In other words, it was designed first and foremost for highway or road course type use...off-road driving was secondary in the original designers' minds. It's a street machine that adapts (sports car first,truck second), not vice versa.
