Acceleration to 100 km/h from a standing start in 3.6 seconds provides the E 63 AMG S-Model with a comfortable lead over the entire competition; the top speed stands at 250 km/h (electronically limited). In addition to the increase in output, this is also attributable in no small part to the performance-oriented AMG 4MATIC all-wheel drive with a power distribution ratio of 33 to 67 percent (front/rear axle). Perfect traction during acceleration effectively avoids slip-induced losses. On the new S-Model the AMG 5.5-litre V8 biturbo engine generates a maximum output of 430 kW (585 hp) and maximum torque of 800 Newton metres -- representing an increase of 20 kW (28 hp) over the AMG Performance package which was previously available as an option. This enhanced performance and power results from adaptation of the engine application, an increase in peak pressure and a rise in the charge pressure from 0.9 to 1.0 bar. At 410 kW (557 hp) and 720 Newton metres, the basic model also boasts an increase of 24 kW (32 hp) and 20 Newton metres over its predecessor. Despite added power and enhanced performance, all models of the E 63 AMG offer high efficiency, low fuel consumption and low exhaust emissions. The AMG 5.5-litre V8 biturbo engine remains the most efficient series production V8 engine around -- with substantially more cubic capacity than its direct competitors. The E 63 AMG rated at 410 kW (557 hp) with rear-wheel drive runs on 9.8 litres of fuel per 100 kilometres in...
