Ferrari 458 M Spied For First Time

I mentioned a while back that Ferrari are working on the 458 M which is the facelift for the 458 Italia and some reports have indicated that it may even be powered by a twin-turbo 3.8-litre V8 that develops 670 horses. These latest spy pics via WorldCarFans show the prototype with a dual exhaust system at the rear but it looks very scrappy so I would wonder if this would carry over to the production model. If they do in fact fit this new prancing horse with a twin-turbo V8, then it may be capable of sprinting to 100 km/h in sub 3 seconds.
