The same 918 test mule wearing the gorgeous greyscale Martini livery we spied doing hot laps of the Nurburgring
last year has been spotted undergoing cold weather testing in Sweden. Alongside it was another 918 wearing a grey "psychedelic" color scheme inspired by the Porsche
917 Martini Racing that ran at Watkins Glen in 1970. For those that need reminding, the 918 Spyder is a new supercar, following the Carrera GT and 959, which combines a 4.6-liter V8 with a pair of electric motors to deliver 762 horsepower.
