Already in its basis version, the SLS provides a significant engine output. But the HAMANN engine department puts some additional power reserves into the V8 engine. Part of the power enhancement is the high-performance exhaust system made out of stainless steel. In combination with a sports air filter, this system also renders the earthy and powerful sound of the 6.2 litre aggregate. The components are precisely adjusted with the help of a new engine characteristic map for motor electronics. With a top performance of 636 hp / 468 kW and a maximum torque of 680 Nm at 4,850 r.p.m, the HAMANN engine exactly meets the wishes of its sports ambitious clientele. The performance enhanced wing door automobile provides first class measures. In race start mode, the two-seater accelerates from 0 to 100 km/h in only 3.6 seconds and with a top speed of 320 km/h, the HAMANN HAWK Roadster also surpasses the basis model.
