Mercedes-Benz launched new S-Class models at the 2008 Paris Motor Show in the form of the S400 BlueHYBRID and a Pullman version of the S 600 Guard armored model. Wheelbase of the latter is 4315 mm (170.0 in) and overall length is 6356 mm (250.2 in).
Described by Mercedes as having "majestic proportions," the Guard version is engineered to resistance level B6/B7. Four rear seats are face-to-face behind a glass partition. Its engine is a V12 biturbo of 5.5-L, producing 380 kW (510 hp) and 830 N·m (612 lb·ft).
Its armor resists military-standard small arms projectiles and provides protection against fragments from grenades and other explosive charges, says Mercedes. Run-flat tires, a self-sealing fuel tank, and a comprehensive fire-extinguishing system are fitted.
Mercedes installs the car’s protective elements—in the doors, rear bulkhead, side panels, roof lining, and firewall—during its assembly and can include areas that would be almost impossible if a retrofitting regime were followed.
Not armored, but also hugely powerful, is the latest limited edition (150-car) version of the Mercedes-Benz SLR McLaren Roadster, designated 722S. The 722 figure was the number carried by the Moss/Jenkinson 300SLR that won the 1955 Mille Miglia road race.
Compared to the regular SLR McLaren, the 722S’s 5.5-L V8 engine produces an extra 18 kW (24 hp), taking it to 478 kW (641 hp). Torque is 820 N·m (605 lb·ft) against 780 N·m (575 lb·ft). The mainly carbon-fiber body is lowered by 10 mm (0.4 in) and suspension stiffened. The engine is hand-built by Mercedes-AMG at Affalterbach, Germany, and the complete car assembled by McLaren in the UK.
