With all that said, we're still a little conflicted when a compelling bit of one-on-one street racing footage comes to our attention. Case in point, the video above. It's our first look at the real-world performance difference between the "insane" mode of the Tesla Model S P85D and the "ludicrous" mode of the new P90D. (For non-Teslafarians, the Model S prefix breaks down like this: the "P" is for performance, the digits represent the battery size in kilowatt-hours (kWh), and the "D" stands for dual motors, indicating all-wheel drive.)
Officially, the difference in acceleration from a stand still to 60 miles per hour is .4 seconds – that's 3.2 seconds for "insane, and a mere 2.8 seconds for "ludicrous." Older Model S EVs offered 0-60 times of 4.04 seconds in Sport mode and 5.2 seconds in the non-Performance version of the dual-motor Model S, the 85D. Not everyone completely agrees with Tesla's ever-quicker official figures, but they're sure getting crazy impressive. How does all of this translate to actual cars in motion? Press play to find out.
