I also think the battery being 50% larger, is worth the weight. These cars can track, but don't belong next to that yard stick.
As I'm these days more of a battery than an engine geek, I got out the 918 promo booklet this weekend and noted the "6.8KWh" available at a steady "200KW" draw. Wow, for the sake of the track. Most PHEVs, at this battery size, are fitting 50-100KW electric motors. So, they aren't getting near that output (~268HP). You do the math (6,800KW for an hour / 200KW instantaneous) and its spent in a couple minutes, but if these VW Group batteries can hold up at these crazy discharge/charge rates (918's tiny battery also accepts a full 20KW charge rate), than I think that's something valuable Porsche is bringing to the track/hybrid table.
In the end, however, the street is a very different application and, to me, Porsche is generously raising the KWh to a point where all-electric performance nears an acceptable level (14KWh). I'd still rather 6 or 4 cylinders, attached to >20 or 40KWh, because then the duration of the battery gets closer to daily use of a car.
