The new Lexus LC500h, hybridised companion to the twin-turbo V6 limousine revealed in Detroit last month, will make its global debut at March's Geneva motor show.

That, however, is the extent of the information Lexus is releasing at this stage, so it remains to be seen which powertrain will drive the new LC500h.

As speculated in January, it could be that Lexus will use the same 220kW 3.5-litre V6 engine and electric motor combo that features in the bold LC500h coupe, offering a combined 264kW of power.

That would leave the LS500h down on the 310kW available to drivers of the regular LS500, although it might still claim a 0-100km/h time in the six-second space.

Will the LS500h round out the new LS range's powertrain options? That too remains to be seen, although a version with the LC500's 350kW V8 may yet appear.

Watch for more on the LS500h to surface in the weeks ahead.
