Developed with security specialists Centigon, the armour fittings include ballistic steel plates against high-velocity ballistics as well as blast protection against 15 kg of TNT, or its equivalent. The under floor protection is able to withstand two DM51 hand grenades. The vehicle's armour fitting is in accordance with European standards. The vehicle also comes fitted with heavy wheels and run-flat tires.
Powering the Discovery 4 is a 5.0 liter LR-V8 petrol engine developing 375 PS and 510 Nm of torque. The huge capacity powerplant is good for a 0 to 100 km/h accerlation time of 10.6 seconds. It sounds kind of sluggish but we have to take into consideration that the Discovery 4 has a curb weight of 3550 kg (not including certain options) given all of its extra padding. That is more than 2 times the weight of a VW Passat 1.8. Expect it to be a thirsty fellow.
Chassis upgrades include an air suspension, new air springs, revised damper settings, biggers roll bars and Alcon heavy-duty brakes to bring all that weight to a halt. The all-wheel drive Discovery 4 Armoured is also fitted with a Terrain Response System which has various settings that adapt to most types of surfaces such as mud, grass or rocks.
I guess the Land Rover Discovery 4 would be suited to ferry high ranking officers in the armed forces.
