IMO - Lotus had big eyes with their original projections. Lotus is a boutique brand with a small dealer network in the US. Based on chart above the Emira blew away previous sale year(s) by a large multiple. They should be happy.
As with any new model, that literally took 3 years to deliver the first cars the US, caused the large bump in the first year. Now that all the people interested have their car, demand has fallen off.
Again just my opinion, The Lotus brand marketing team stinks. They let the car magazines (in the US) eval basically an early demo car with loads of issues (360Hp turbo car) and may people lost interest. (DCT issues, low power, etc). They should have waited vs allowing crap articles that live forever on the internet.
Lotus was also foolish to put initial pricing at $77k (was never going to happen) diminishing the premium brand and setting improper expectations.
Last once the revised Turbo landing in the US Lotus Marketing didn't --push-- all the magazines to re-eval...such morons (or they don't have Marketing budget).
Only C&Ds 'Drivelines' team published a one-pager in the back of magazine. Just sad.
This was the only article, since the revised car entered the US market.
Personally, I like that I don't see Emira's on the roads ... compared to Porsches at every other stop light. Downside, is with such a low volume of cars in the US the dealer network is going to suffer.
