I think you are misestimating. Toyota sells ~1.5 million hybrids (plugin and otherwise) per year. If I'm not mistaken, the average capacity is ~6kwh. That works out to 9,000,000 KWh (9 GWh).

Tesla sold about 250,000 cars last year, with an average pack size of at least 70 KWh. That works out to 17,500,000 KWh (17.5 GWh).

Obviously, these are estimates, but Tesla is also running at a pace closer to ~320k units for next year with only marginally smaller pack sizes.

Revenue is another interesting metric. Toyota is at ~280 billion/year (USD). Tesla is currently at ~27 billion/year.
