GKN AU­TO­MO­TIVE is test­ing a torque vec­tor­ing elec­tric drive sys­tem at the com­pany’s Win­tertest prov­ing ground in Swe­den.

Called the eTwin­ster, the gear­box is meant to of­fer au­tomak­ers a com­bined so­lu­tion for hy­brid and plug- in all- wheel drive plat­forms.

It’s a com­bi­na­tion of the eAxle tech­nolo­gies GKN pro­vides for com­pa­nies like Volvo, Porsche and BMW, and the twin- clutch torque vec­tor­ing fea­tures the com­pany cre­ated for ve­hi­cles from Ford and Range Rover.

GKN built a pro­to­type ve­hi­cle for test­ing based on a pre­mium SUV. The pro­to­type uses a 240 Nm elec­tric mo­tor and gaso­line en­gine.

With ra­tios, a to­tal pro­duc­tion of 2 400 Nm of torque is sent through the dual- clutch eTwin­ster sys­tem. Ve­hi­cle dy­nam­ics ex­perts from sev­eral lead­ing au­tomak­ers are cur­rently test driv­ing the pro­to­type ve­hi­cle.

The high amounts of torque mean that the pro­to­type re­ceives more propul­sion power from the elec­tric mo­tor than it does the com­bus­tion en­gine.

The com­pany says that the eTwin­ster will be ready for pro­duc­tion ve­hi­cles within the next three years and pre­dicts that by 2025, about half of all ve­hi­cles pro­duced will have some fort of elec­tri­fi­ca­tion ( hy­brid, plug- in).

To that lat­ter end, GKN is de­vel­op­ing a range of elec­tric- drive sys­tems meant to aug­ment or boost the power pro­duced by the elec­tric mo­tors in hy­brid and plug- in ve­hi­cles. — Wheels Reporter.
