Standard Model 3 performance

[bwilson4web]

Hi,

So I remain curious about the two, standard range, Model 3:

• (5.3-5.6) / 5.3 = -5.7% slower acceleration
• (240 - 220) / 240 = -8.3% shorter range
• (140 - 130) / 140 = -7.1% slower top speed

These numbers suggest the differences are aerodynamic. The loss of range, -8.3%, and top speed, -7.1%, are conducted at higher average speeds where aerodynamic drag plays a bigger role. In contrast, the -5.7% acceleration occurs with significantly lower speeds, 0 mph to 60 mph. Speculations:

1. rear spoiler missing
2. underbody liner missing
3. fixed open air inlet
4. wheel covers (aka., hub caps)

I can't rule out higher rolling drag tires. But these tend to be speed independent and the range of -5.7% to -8.3% is a little too wide of range to be just tires.

There could be a control law designed to reduce drive train efficiency. However, these are more difficult, not impossible, to diagnose. So I would look for unexpected heat.
