In these spy shots, we see the limited-production version in its latest stages of development. It looks quite far along, with a monochrome racing stripe scheme in place of the typical camouflage and a completely finished exterior. Even the clear cover over the engine--which appears to have top-mount exhaust outlets-- is in place.
The sleek, aerodynamic shape is very close to the concept version of the car, and the rear wing is deployed--though it's not yet clear if it's active or fixed. Relocating the exhaust outlets from the side of the car, as on the concept, to the top of the engine bay, could be about keeping the batteries or other components cool and comfortable. The car also appears to have a removable hard top roof insert to transform the car into a near-coupe-like vehicle.
If you've already forgotten, the 918 Spyder is powered by a 500-plus-horsepower 4.0-liter (or larger) V-8 engine at the rear wheels and a pair of electric motors good for a combined 218-horsepower, one at each axle.
The combo enables the 918 to rip off sub-3.2-second 0-60 mph runs and a top speed of 199 mph--and yet it's capable of up to 78 mpg. Porsche has said the 918 Spyder offers up to 16 miles of all-electric range. A lithium-ion battery pack supplies the electricity, and can be charged from the wall in about 3-6 hours.
Porsche gave the 918 Spyder the green light for production back in July, 2010, after reaching a 1,000-buyer threshold the company had set as the benchmark for sufficient interest to support production. The order books opened on the car last March, at a price of $845,000.
Porsche says it plans to build just 918 of the cars. It is due to arrive to the lucky few around the end of 2013.
