Porsche isn't about to let the LaFerrari steal the hybrid spotlight: it just unveiled the finished design of the 918 Spyder, which is expected to ship as a 2015 model. The look won't shock anyone keeping up with their spy videos, although Porsche's formal unveiling helps firm up the specifications that customers will get if they've dutifully shelled out $845,000. The performance is even more intimidating than it was in 2011, we know that much: there's 887HP of combined V8 and plug-in electric power, a 0-62MPH time of 2.8 seconds and up to 18 miles of gas-free driving. About the only disappointment (price notwithstanding) is the lack of options beyond a weight reduction package. We doubt many Spyder buyers will complain when they can even outrace a 911 GT3.
