Car chases seem to be an increasing part of law enforcement activity.
Conventional cars appear poorly adapted for such pursuits.
BorgCo are developing a specialist vehicle for such situations.
The car is rear engined and air cooled. Thus the powerplant is not vulnerable to incoming fire, and
there is no coolant to leak. The transmission is four wheel drive. Speeds comparable to those of high-end passenger vehicles are achievable.
The wheels and tyres are protected by armoured "spats".
The front of the vehicle has a layer of sloped composite armour capable of withstanding small-arms fire. This is continued by a sloped armour-glass windscreen in front of the driver, with sloped glass armour to the sides as well.
The gunner sits in the passenger position, set back from the driver but with a 120 degree field of fire. Armour glass again provides protection for their head, below which is a swivelling casemate/barbette through which weapons can be fired.
Thus the vehicle can approach a fleeing car closely, and deliver high-volume accurate fire, without risk to the officers from return fire, rapidly ending the pursuit.

If the body of the vehicle is armored, then why is the
engine not protected such that it can be water-cooled? Are
you not aware there is a significant lesser maximum
horsepower rating for an air-cooled engine vs a water-
cooled engine? I don't see how, with the engine you
propose, this car can keep up with a high-speed
thiefmobile. |

The engine will be fairly well protected as is, so yes, liquid cooling is possible; but radiators are always a vulnerable spot. |

For the same capacity, yes ... but a flat-4 300HP Lycoming unit fits in ther same engine bearers as a 180HP unit, and it doesn't weight much more. Just throw in a turbocharger or a supercharger. |

Modern engines can be arbitrarily powerful. The tradeoff is fuel consumption, reliability, and service life. The taxpayer's footing the fuel bill, so that doesn't matter. Frequent servicing is a given. So as long as it's reliable in service, i.e. doesn't die in the middle of a pursuit, the rest is irrelevant. |

OK, but what you basically have here is a batmobile. |

Perhaps Vernon was thinking of water-cooling as in the Vickers gun. |

For discomforting the Ungodly, we would prefer an L4A9, which
is accurate for single shots yet can put a respectable amount of
lead in the air in a fairly short time. |
|

I think in your combined excitement at correcting my typo (now fixed) and the mention of weaponary you've missed the point, because as far as I can see the L4A9 was not water-cooled.
I was merely suggesting that rather than using a radiator, one could vent off steam. |

That's rather what I was thinking, [Loris], although I suspect Batman would eschew the gun. Perhaps a batmobile after customisation by Deadpool would approach this idea more closely. |
