Differences in roadster versions

[frequencydip]

Does anyone know what changed form version to version, i.e. 1.5 to 2.0 to 2.5? I'm looking to build a comprehensive list.

VIN #500 was the last 1.5

Any such list won't be entirely accurate, because Tesla phased in a lot of upgrades as they became available, and in some cases retrofitted cars already on the road.

There are old threads you can find on this forum that describe most of the differences.
The biggest change was 1.5 -> 2.0 (at VIN #501) where they switched to a new motor/PEM. You can tell those right away from the VDS in the center (instead of to the left) with the push-button direction selector (instead of "stick-shift"). That is also when they removed the tach and replaced it with the kW power meter.
Soon afterwards they introduced the sport variant. The changes from 2.0 to 2.5 were more cosmetic. Perhaps the revised front and rear bumpers are the most noticeable... And the double DIN dashboard NAV upgrade option.

There is a whole history of seat upgrades. And exterior color options...

The Sport model was available at the start of the 2.0/2010 models. #502 was a Sport:

I think that qualifies as "soon"...

2.5 also had PEM upgrades.

I had taken a "stab" at figuring out those production numbers before.
Mentioned here:
Where they now? The first 100 Roadsters

I think in 2006 they may have made 10 EPs.
I think in 2007 they may have made 14 VPs.
I think in 2008 they may have made 17 VPs, 27 Founders' and 100 signature models. (Plus around 400 more regular production models.)

I might be wrong, but I think they delivered #501 as a non-sport customer car, but held onto #502 for internal evaluation for a long while (but eventually sold it I think.)
As I recall there was a bit of a delay between the first 2.0 customer delivery and the first "2.0 sport" delivery even though you are right that #501 is the first 2.0 and #502 is the first 2.0 sport.
