Jalopnik has more on the Tesla Model S P85D:
Elon Musk concedes that “the Internet is very good at figuring out secrets.” So yes, the D in the Tesla Model S P85D stands for “dual” motor. Yes, it’s the same system coming to the all-wheel-drive Model X. But here’s what we didn’t expect: 687 lb-ft of torque and a 0-60 MPH run of 3.2 seconds – a full second quicker than the standard P85.
Oh, and 1g of lateral acceleration. In other words, it’s obscenely fast.1
Before I get into what it’s like to be in one, here’s the breakdown on what’s been done and what’s on offer.
The top-spec Model S, the P85D, comes in at $120k (with both the performance and tech packs required). That gets you two motors: the same biggie-sized one out pack in the standard P85, and then a smaller motor fitted up front. That new motor packs an additional 221 hp into the S, with the rear motor dolling out 470 HP, for a combined 691 HP. Plus a quarter mile time of 11.8 seconds (down from 12.6).
