While most of you are waiting to see a production version of the Porsche 918 Spyder, our spy photographers have caught two new prototypes during their first cold weather testing in Northern Sweden. As you can see, one of the prototypes is still wearing that cool white Martini racing livery, while the second one is wearing a cool grey racing livery.

Just as a reminder, the powertrain of the 918 Spyder->ke3629 will combine a 4.6-liter V-8 engine delivering a total of 570 horsepower with a pair of electric motors - one powering the front axle and one on the rear. This hybrid system will deliver a total of 795 horsepower and, according to Porsche, it will hit a top speed of 202 mph.

The car already scored some amazing results, as it lapped Nurburgring in a time of 7:14.

The production version will debut in September 2013 and will be priced at about $1 million.
