Tesla Factory Racing To Retool For New Models

An anonymous reader notes this story about what Tesla will have to do in order to double production every year for the next several years as Elon Musk intends. "Having just reported a $107.6-million fourth-quarter loss that sent its stock tumbling, Tesla Motors Inc. intends to double vehicle production in the next year as it finally introduces its Model X sport utility vehicle — after about two years of delays. Meanwhile, Tesla is racing to finish the design of its Model 3, the "affordable" Tesla, expected to sell in the $30,000 range after government subsidies. Musk's company is chasing General Motors Co., which plans a 2017 release of its all-electric Bolt, with a similar price and 200-mile driving range between charges."

Re:if by "much higher efficiency" you mean 40% vs

[beelsebob]

1) You missed out the "transmission" losses for the fuel (it takes roughly 1.2 gallons of fuel on average to transport 5 gallons of fuel to the petrol station)
2) You missed out the transmission losses for a mechanical car (around 30% of your energy is lost in the gearbox/diff/...)
3) EVs are actually about 90% efficient, not 40%.
4) Power plants are roughly 50-60% efficient even if you assume you use fossil fuels to generate the power.

What this adds up to:
Fuel powered car = 80% (fuel tanker efficiency) * 26% (engine efficiency) * 70% (transmission efficiency) = roughly 15% efficient total system (ignoring the amount of energy it takes to dig up the fuel and carry it to shore)
Electrically powered car = 60% (power plant efficiency) * 94% (power grid efficiency) * 85% (charging efficiency) * 90% (engine efficiency) = roughly 43% efficient total system.

Add to that that you hypothetically in the future can then replace the fossil fuel burning power plant with a {nuclear | wind | solar | ... } one, and you get a rather huge win. You're literally using one third the power to drive your vehicle.
