Using a different angle (I couldn't resist), if we assume that the Plaid powertrain is similar to the Roadster 2.0, battery would be 200KWh. So 500 vs 620 miles for a much bigger vehicle... Not impossible if the weight is not much more than a Model X. With adapted tires and battery/powertrain weight reduction, the Cybertruck AWD may be doable with 100KWh pack.
Oh yes, this is the obvious move to leverage existing tech. Let's flesh out the Cybertruck Lineup:
- $40K CT RWD (CTR): late 2021 - Est'd 17% of Production
- Model 3 powertrain from LR: (avail now)
- single SRPM rear drive - GF1
- 75 KWh bty pack - GF1
- 325/250 mile range M3LR/CTR =
- Est'd 1.30x energy consumption for CTR
- $50K CT AWD (CTA): late 2021 - Est'd 42% of Production
- Raven powertrain from Model S/X: (avail now)
- Performance AC induction rear drive - Fremont
- Model 3 SRPM front drive - GF1
- 100 KWh pack built with 18650s - Fremont+Japan
- 375/300 mile range RS/CTA =
- Est'd 1.25x energy consumption for CTA
- $70K CT Tri-Motor (CT3): late 2022- Est'd 41% of Production
- PLAID powertrain from Model S/X/R2: (avail Summer 2020)
- 2x Model 3 SRPMs w. dual drive rear - GF1
- Model 3 SRPM front drive - GF1
- 200 KWh pack built with 'Maxcells' - t.b.d. (Summer 2020)
- 620/500 mile range R2/CT3 =
- Est'd 1.24x energy consumption for CT3
See how nicely the announced ranges for the three different Cybertruck variants align with these existing powertrains? Let's spell it out more compactly:
- Model LR RWD 1.3x range of Cybertruck RWD
- Model S RAVEN 1.25x range of Cybertruck AWD
- Roadster 2 PLAID: 1.24x range of Cybertruck TRI
Now, making these assumptions, we can estimate Cybertruck energy consumption per variant:
- Cybertruck RWD:300 Wh/mi <= Ed. Note: That's 100 MPGe in a TRUCK!
- Cybertruck AWD: 333 Wh/mi
- Cybertruck TRI: 400 Wh/mi
Note that CT/Tri-motor consumption rating is slightly high. I think its likely CT/Tri has either 600 miles of range (assume empty, same eff. as CT/AWD) or that it only needs a 150 KWh bty to achieve 500 miles range. Or perhaps Telsa wants to give you 500 real world miles of range while towing, or off-road racing, or rolling a big damn MegaAmp (pumpin' out the jams like
@SpaceCash)
So I think this is close to
Tesla's plan for their 3 Cybertruck variants:
- it leverages existing technogy and production facilities to speed product launch
- it minimizes R&D expense by reusing existing powertrains
- it minimize CapEx by spreading major components across existing production lines
- it defers the most complicated variant by 1 year to allow completion of already in-progress R&D efforts (Plaid powertrain), again minimizing new CapEx
In summary, I think this is the way Tesla doubles their
TAM (total addressable market) esp. within the U.S. with virtually
ZERO NEW CapEx. Their major remaining engineering expense will be learning how to mass produce vehicles bodies in Stainless Steel.
Now if only there was some friendly company will aligned goals with which Tesla could partner to share those expenses and accumulated engineering know how...
If only... /S
Cheers!
P.S. Who wants to estimate the weight of the 3 Cybertruck variants, given their target 0-60 times from the reveal, and the known values for acceleration and weight achieved by the existing Tesla models on which those Cybertrucks variants are based?
Bonus Points: How
quick will Cybertruck be on Mars (0-60 mph)?
