The Tesla Model S P85D hit the market last December and Consumer Reports did what they do best; they evaluated the heck out of it. The electric luxury car performed so well in nearly every test that is somehow managed to rack up 103 points in a system that doesn’t go past 100. Essentially, the P85D is the best performing and most energy efficient car Consumer Reports has ever tested – so much so that the test team had to overhaul the scoring system just to make sense of the car’s amazing rating.

The P85D’s astounding 103-point rating is a calculation of “raw” points, which it earned by performing so much better than the standards by which cars are judged. The Model S variant scored so well, in fact, that Consumer Reports was forced to reconfigure its scoring methodology to account for the car being so awesome. It was the P85D’s insanely responsive acceleration and incredible energy efficiency that blew all expectations out of the water.

The Model S P85D variant astonished Consumer Reports testers when it proved to need only 3.5 seconds to go from zero to 60 mph. That makes it the fastest accelerating car the company has ever tested. The P85D also beats out the original Model S in energy efficiency, clocking in the equivalent of 87mpg when the base model achieved a maximum of 84mpg.

The folks are Consumer Reports feel that the stellar performance of this electric car is an indication of where the automotive industry is headed. “The P85D represents a glimpse into the future of automotive technology in which cars will be more energy-efficient than ever, while still delivering a terrific blend of performance and practicality,” said Jake Fisher, Consumer Reports director of automotive testing. “The Tesla is a shining example of how higher fuel economy standards can be achieved without sacrificing performance.”

Consumer Reports previously rated the Model S as the best-performing car ever tested when it earned 99 points in 2013. Nobody was really expecting another vehicle to surpass that achievement anytime soon. It really shouldn’t be much of a surprise that the car to overtake the Model S is simply the latest variant. Consumer Reports has published the complete test ratings online for public viewing at no charge (unlike some of their other product tests, which are accessible only with a subscription).
