The off-road capability is good mainly due to the torsionally bending frame. This generally results in slow movements that drive the eye torsionally out of Listing's plane. It also results in a torsionally stiffer construction for both the crankshaft and crankcase. The buttressed core supports itself both laterally and torsionally. The accumulated length of main bearing journals gives a relatively torsionally flexible crankshaft. This innovative system allows the structure to support itself both laterally and torsionally. It is designed to be flexible, while remaining torsionally strong under high torque loads. Torsionally stiff and still flexible, disc couplings are a great solution for high speed applications. The Vanquish Volante is 13% torsionally stiffer than the outgoing DBS Volante.
