Porsche 918 Spyder review

The main choice is whether to Weissach or not. Apparently 60 per cent of buyers do. The kit costs £60,000 and saves 41kg. The biggest ticket item is the lightweight magnesium wheels (saving 14kg), but as ever, it’s the little things that are more interesting and telling. Ceramic wheel bearings save 700g, a carbon fibre bonnet support is 500g lighter, while carbon shift paddles and leather looped door pulls each reduce weight by 200 grams.

Initial reports suggested Porsche was struggling to sell all 918 cars in the production schedule – hardly a surprise given the volume involved is significantly more than the Ferrari and McLaren put together. But more recently things have looked up. It remains to be seen how it will age over time, but so special is it in both concept and execution, we’re sure long term values will hold up over decades.
