Good starter list. I am sure there are a few more . I am glad that there are so many product offerings and that you have acknowledged that it will be coming in the next 18 months. A few may be there in 6-9 months, most others will be in the 12-18 month period at least in the US.
Here is my problem and concern. There is a lot of hype about these cars (especially range, features) and how they are going to be Tesla Killers. Some of them are not even in the market that Tesla is (ID3, Mini) and ID3 may not even be introduced in the US market. US market does not appear to be as receptive of small low range cars as say Europe or Asia.
The first issue is that when the rubber meets the road, the car do fall short in some ways even though they may be better in others. Range is one area: Both E-tron and I-Pace promised a lot higher range but under EPA ratings dialed it down considerably. Even though the Taycan and EQC claim about 300 miles, they are not EPA numbers and will be lower when introduced to the US market. EQC website still mentions it in KMs. Tesla has been at it for years and has been improving the products. These manufacturers can accelerate the learning curve (due to having a reference point already and being able to use newer technology), but may not be able to leapfrog over Tesla on the first go. They need to keep working on it.
Second, these manufacturers have not reached the volumes that are needed to really challenge Tesla. Many companies are just focusing on California (Honda Clarity PHEV has been withdrawn from all other markets, so that they can meet CA demand) or to meet compliance needs. They may have supply chain problems, especially with batteries. So I do not them really going after Tesla, (other than at the margins) at least in the next 15-18 months.
Third, this is not a zero sum game, that another manufacturers gain means a direct loss to Tesla. The market is expanding, so Tesla can continue to grow as do others.
So I stand by my usual pronouncement, that while there may be dark clouds over the horizon for Tesla, they are still far away and Tesla has time to prepare for the storm.
