@Reality Checker Well-said.

Although they don’t win in all areas, Ford’s pursuit-rated vehicles have been well-received:

And the Special Service Police Sedan (ahem, 2.0L EcoBoost Taurus) can call itself the most fuel-efficient police vehicle in the US of A:

I’d also like to add that in GM’s case, PPV could also stand for “Police Patrol Vehicle”, or “Police Package Vehicle”.

And my money is on Ford delivering a pursuit-rated truck first.
