I bet those 4 people who disagreed with my post and scaesare haven't looked at Tesla's SEC filings and seen what expenditures are actually causing losses and what are not.
To put it another way... All EV's are encouraged by governments at various levels in the United States and other parts of the world to varying degrees. In the United States, there are 4 primary incentive programs. CAFE fuel mileage standards, CARB ZEV credits, federal tax credit for alternative fueled vehicles, and various state level incentives that might or might not exist that include purchase tax credits, HOV lane access, and so forth.
If all of these were removed, then vehicles like the Leaf and the Bolt wouldn't exist. Tesla would try to exist, but it would be much harder. If it were 3 years ago, then Tesla would have a very hard time.. but with the achievement of the Model 3, Tesla may become immune pretty soon. All Tesla vehicles are pretty competitive at their price points... the federal tax credit does help, but not a back breaker. Tesla does get CARB ZEV credits, but can only monetize them at roughly 50% the amount that major automakers can due to not having ICE vehicle sales to book against. Tesla isn't affected by the CAFE fuel mileage standards directly... the removal wouldn't cause a financial impact, but other automakers would have less incentives to push higher mileage vehicles. It may increase Tesla's competitive position. The CARB ZEV credits and CAFE fuel standards compliance baked into the accounting for vehicles like the Leaf and the Bolt. They can afford to have negative gross margins on both vehicles because of the effects selling these have on the overall CAFE fuel mileage average and the CARB ZEV credit mandate. They need to sell somewhere around 20,000 to 30,000 ZEVs or many more TZEV/PZEVs in accordance to how many non-EVs they sell.
The Bolt is price competitive at roughly a $25,000 to $28,000 price point. Given the unit volume, they can't amortize the typical $1 billion in platform development costs across a large number of vehicles. If they can achieve 225,000 vehicles sold across 5 years, an average of 45,000/year, that's $4,500 in R&D costs per vehicle. That means COGS has to be less than $20,000. And clearly, that's not the case. And 45,000/year is about double what they will do in 2017. That's why Nissan has been reluctant to make large changes to the Leaf. The 2018 Leaf is really Leaf 1.5. Their original development costs are spread across ~300,000 vehicles... or if you take the entire Renault-Nissan alliance, across ~425,000 vehicles. It took them about 7 years. The new Nissan Leaf will apparently have a build plan of about 90,000 vehicles worldwide. Nissan is hoping that the relatively modest changes they made can have a big impact on the overall financials for the Leaf, especially if they can reduce the massive amount of cash on the hood they've bee offering for the older models.
The Model 3 is price competitive against the Audi A4, BMW 3 series, and Mercedes C-class straight up without federal or state purchase tax credits. We can argue about whether the Model 3 is a mass market vehicle and what mass market vehicle even means, but at least the Model 3 is a true straight up competitor in its segment and that segment can support millions of vehicles of volume worldwide. The Leaf and the Bolt are not price competitive against their segment competitors. But due to the CAFE and CARB ZEV credit situation, both GM and Nissan have been willing to put a lot of cash on the hood to move these vehicles.
That's why the Model 3 is a big achievement. It isn't just the vehicle itself, but a vehicle that is both feature and price competitive against ICE vehicles within the same segment and with sufficient volume to amortize the investments to be profitable overall. The build plan for the Model 3 is roughly 1,750,000 units over 5 years. That's a big difference than even the most optimistic projections for the new Leaf over 5 years. The Bolt's build plan is not even close... roughly 30-40% of the build plan for the Leaf and maybe 15% of the Model 3. Of course, these are all comparing rosy projections for which the companies are actually investing to achieve.
