Now how secure is a Jaguar XJ Sentinel well to start the Jaguar has B7- Level armored protection which means the car will be able to withstand a blast up to at least 30-lbs of TNT and at close range. This Jaguars armor is heavy strength steel with Kelvar backing that is built on top of the aluminum chassis so the car will be able to withstand any impact of arms fired directly toward the vehicle. The main focus was improving the armor and embedding it in the body to direct impacts from most machine guns and heavy armor piercing rounds.
Now since the car weighs heavier from the armor it is still capable of still carry weight up to 1,100 lbs and still able to reach top speed of 121 mph in 9.7 seconds. Which is good to know what it is capable to outrun potential threats.
The XJ Sentinel carries a naturally aspirated 5.0-liter V8 engine with a six-speed automatic transmission which powers the vehicle. It can produce up to 385 horsepower that can actually move a 7,275 pound vehicle to at least 62 mph at just under 10 seconds. Never claimed it was a fast vehicle but the worth is in the protection that it gives. Now considering all the weight of the vehicle has gained it has reinforced brakes and suspension able to bring this car to a complete stop.
