Teslalta saatavilla uusi kolmella moottorilla oleva Model S. Pikku miinuksena hinta on melko kova.
Käteishinta 145 280€. Pitäisi tulla Q4 2021, eli noin vuoden päästä. Ei varmasti lopu tehot kesken.
Teslan lupailua:
Kiihtyvyys 0–100 km/h: <2,1 s
Neljännesmaili: <9,0 s
En ole katsonut, mutta toivottavasti näin

Intro
Cost to produce factories is decreasing with each factory
Megapacks are 3 MWh
Over 1M vehicles delivered
26B miles driven
5 GWh of stationary batteries installed
17 TWh of solar generated
Cell Production
0.1 TWh produced in 2019 for vehicles
10 TWh goal for vehicles requires 100x growth (1.5 TWh for small/robotaxis I, 3.5 TWh compact/midsize, 0.9 TWh luxury/suv, 1.1 TWh pickup truck, 3 TWh Semi and commercial)
0.006 TWh produced for grid storage in 2019
10 TWh goal for grid storage requires 1600x growth (2.3 TWh for non-renewable electricity, 1.4 TWh for coal heating, 2.1 TWh for gas heating, 0.8TWh for oil heating, 1.5 TWh for future EV, 1.9 TWh for future growth)
Need to get to 20 TWh of production per year for all companies (135 NV gigafactories – 150 kWh/year)
$2T investment required (for all companies)
2.8M people required (for all companies)
New Cell
4680 cells (5x energy, +16% range, 6x power, 14% $/kWh reduction - due just to new cell with tabless electrode)
Tab-less electrode allows for better cooling with 50mm vs 250mm electrical path
Planning for 10 GWh of production within a year
Aiming production of 200 GWh at each Gigafactory
Dry Battery Electrode (DBE)
10x footprint reduction
10x energy reduction
On v4 of the DBE machine now
New production DBE machine versions every 3-4 months
Continuous motion production
20 GWh per assembly line (7x line output increase)
Battery formation (verification) (86% reduction in investment, 75% reduction in footprint)
75% investment reduction
18% cost reduction due to DBE at the pack level
100 GWh production goal in 2022, 3 TWh in 2030
Tesla Silicon (raw metallurgical silicon with surface stabilizing polymer coating, $1.2/kWh, adds 20% more range to vehicles with just this addition)
Silicon annode provides a 5% cost reduction at the pack level
Cathode
High nickel cathode with
no cobalt (15% reduction in $/kWh)
Iron for large stationary storage and medium range vehicles, nickel manganese for higher range vehicles and Powerwall, high nickel for high range vehicles (Semi and Cybertruck)
Cathode production is being brought in-house to reduce production cost and complexity (66% investment reduction, 76% process cost reduction, 0 waste water, 80% reduction in material miles travelled. Also enables simpler cell recycling)
Lithium
Lithium production is being brought in-house (33% reduction in lithium cost, 100% electric facility co-located with the cathode plant)
Acid-free lithium extraction from clay using salt
Tesla has secured a TWh-scale lithium resource in NV (10,000 acres)
Tesla lithium production results in 12% battery cost reduction at the pack level
100% of batteries are being recycled
Tesla is bringing recycling in house
Cell to Vehicle Integration
Largest casting machine in the world to produce single piece castings for front and rear underbodies (40% cost savings, 79 fewer parts per car, custom alloy, no heat treatment required)
Battery pack will be structural, not cargo
Saves more mass in the rest of the vehicle than the non-cell portion of the battery
Cells are more densely packed because less internal structure is required
Filler is structural adhesive and flame retardant, gluing cells to top and bottom plates for shear strength (if it were in a convertible it would be stiffer than a regular car)
Castings enable evenly spread loads into the batter pack
Cells can be moved inwards to protect them in case of side collision
Reduces polar moment of inertia
10% mass reduction, 14% range increase opportunity, 370 fewer parts
Body+ battery Factory (55% reduction in investment per GWh, 35% reduction in floor space)
7% $/kWh reduction at the pack level
Total for all of the above
56% $/kWh reduction at the pack level
54% range increase
69% investment reduction per GWh
Will begin to realize these improvements in 12-18 months
3 years to completely realize the improvements
Will enable a compelling $25,000 car in 3 years
Model S Plaid
0-60 in less than 2 seconds
200 mph
1/4 mile in less than 9 seconds
Greater than 1,100 horsepower
Greater than 520 mile range
1:30.1 Laguna Seca lap time
Available in late 2021
