Tesla's model S and X cars reach the end of their product's lifecycle and will need a serious upgrade if the company wants to keep a luxury price, a car analyst told CNBC.
"If you claim that demand is huge and unlike mited then the key question is why do you lower your mix? Why are you lowering your pricing? "Ellinghorst added.
The analyst said Tesla CEO Elon Musk, in his call to investors, had not been very aware of a pricing strategy to maintain demand, adding that Model S, first introduced in 201
"I believe that S and X are pretty advanced in any normal life cycle of a product so they would really need substantial updating to restore prices . "
Tesla introduced Model 3 since 2017 and unveiled a compact SUV, known as Model Y in March this year.
Model Y is an attempt to grab the hugely popular SUV market, which predominantly dominates the US car market.
"We will probably do more Y than S, X and 3 (sales) combined," claims Musk in March, when Model Y comes to market by 2020, which would be more than 1 million vehicles.  Ellinghorst said both Model 3 and Model Y w ould attract buyers, but musk's promise of a million sales so unrealistic, saying that pressure from rival German car manufacturers would make it difficult to enter the car markets in Europe and China with anyone real scale.
"The mark will be less exclusive than it has been in the past," he said.
