The current TDV6 is around 250BHP and yet the smaller Sport has around 300BHP. Do you think this more powerful engine will find it's way in to the L405. I was going to place an order soon and this is quite a fundamental change.

Don't know, but it's all change this year as the EU6 emission laws come in. Rumour is the V8 diesel dies, but I don't know how true that is. Can't see it myself as they sell loads of 'em, but if they were to intruduce a 300bhp V6 they'd need to up the power of the 335bhp V8.

SDV8 has apparently been adapted for Euro6 with SCR and start/stop - supposedly around until 18MY.

I asked the same question on Pistonheads, my dealer indicated (wrongly) that this happened in MY15.5 changes...maybe its further down the line. I cant see why they would not carry over the engine.

Update:

I asked LR customer services if it was in the pipeline, they said no and pointed me in the direction of the hybrid.
