Tesla should undoubtedly offer a Performance Motor Option with the S2. I am an enthusiast who values efficiency and performance and a Model S reservation holder. Also, $90K is a bit over my budget .
Based on the motor spec sheet here: Model S Options Pricing | Tesla Motors, I have plotted the power curves of S3 Performance, S2 Standard and my proposed S2 Performance here:
From the graph above, from 0 to 3000 RPM, the S2 Performance has the same power as a S3 Performance, but is a few hundred pounds lighter. What this means is that the S2 Performance package will be the fastest Tesla off the line - even quicker than the Roadster Sport from 0 to 30 MPH! In fact, if Tesla optimizes the battery pack, I imagine they could off more than 225 KW with this package, making the 0 to 60MPH as fast if not faster than the S3 Performance.
Besides off the line acceleration, from a customer standpoint there are other advantages of the S2 Performance over a similarly priced S3:
1. Much lower cost.
2. Much better vehicle dynamics since it is a few hundred pounds lighter, the S2 Performance Option will out brake and out corner the heavier S3.
3. More efficient since it is lighter and will have lower rolling resistance. Efficiency is one of the reasons why we buy an electric car. I don't need 300 miles range and do NOT want to carry the extra battery weight that comes with a S3 every day.
Tesla could price the Performance Option upgrade easily from $5K to $10K. If interested in a S2 Performance Option, please respond to this post so Tesla sees that customers want this.
