Sorry, lousy camera phone pic in a dark parking garage, but at least it has a banana for scale. The frunk is indeed a lot smaller.
The P85D is, of course, an extremely nice car to drive. It was notably faster and more stable than our early-VIN S85.
That said, as a Roadster owner I was a little disappointed. My expectations were no doubt too high, but I was hoping the change from 3.9 in the Roadster to 3.2 in the P85D would be very notable. It didn't seem like a really significant difference - the Model S is smoother, quieter and you're not as low to the ground, so there's probably a lot of perception involved. Plus the more-than-a-ton weight difference between the two is still obviously notable, even though the P85D seemed very sorted. And the Roadster's steering feel is better (the P85D steering is very good, but the steering feel is still a little numb). I prefer the Roadster's steering and handling, although this was at legal speeds - on a track the Roadster's understeer might change my mind.
To me, trading a Roadster for a P85D is definitely not a must-do for fun-to-drive reasons, but the P85D really is a great car so I wouldn't be at all sad to make the trade if I had to for practical reasons. It is faster, smoother, quieter, far roomier, far better ride, has more range, AWD, Supercharging, Autopilot, etc. And yet the base P85D still comes in a tiny bit cheaper than the base Roadster was.
