Tesla is the market leader and will continue to be one for the foreseeable future. The question is who is number 2 (Nissan claims Leaf sells more cars worldwide but they are not serious contenders in the US). Now if Jaguar can sell about 25000 cars or more, they are at least contenders in the high end market, they may be number 2. However if they sell only say 5000 cars a year, it may not take much for others to have a large market share in the same segment. Jagur has an order of 20000 cars from Wyamo (but that is over a period of time). That is an advantage right there as they might be able to provide say 5000 on a contracted sale. So 20,000 to 25,000 cars in the first year is not that much of a stretch, if they can manufacture it.
