The M139 block was mentioned in some prior interview (cannot find now). As to 416 Hp yes coincidentally the higher output of the M139, yet must also be considered that Mercedes has not certified that power level in the USA. As the to V6 at 416 PS or 416 Hp again in the US we got the Evora GT which started at 430 HP but with 3rd Cat and detune for mountain states gas (down 2 points from true Super) it ended up at 416 Hp (421 PS). Also was pretty clear in the interview that Matt was talking about the V6 when he said 416. Time will tell. I do believe that Lotus is being coy about weight and power pending regulatory sign off. In US prior to the GT launch we were told it would be the GT430 at 430 Hp, then at order time 422 (i.e. 3rd Cat added back on), and then finally 416 .. one spec for all states. A larger number of us were pissed at the time, for that and other spec changes. Similar thing on weights, different standards, EU, DIN, SAE .. in US the weight for certification much include the options selected by 30% of market. Well this is probably one reason why we are currently being poled by Lotus USA as to what options we plan to order, the other i'm sure is for SCM and production scheduling plans.
