Considering that the Evora Roadster is one of the most eagerly anticipated Lotuses to date, and having myself driven all versions of the Evora up to the 400 (I have yet to try the 410), and also understanding that this forum is often looked at by the Lotus people themselves (so I hear anyway...), I started to ask myself what would really get me out of my Exige S and into Evora Roadster ownership.
Here's what I think would seal the deal for me.
Make it a real Cayman GT4 beater.
That means more power, or less weight, than current Evoras, so that the power-to-weight ratio really goes up. It also means more practicality than my Exige S, which is a stunning car that is easily capable of humbling 911s all the way to the 997 GT3 (991s GT3s are a little out of the Exige's reach), but which really forces me to make strong compromises when I go touring with it.
So if the Roadster is going to be a 2-seater only, then make sure there is space behind those seats for luggage and stuff, because the current Evora's boot is way too small to be able to compete with the 981/718 platform with its 2 boots front and rear.
Also, give it an innovative roof that is light, practical and eye-catching. Once again, the current Boxsters are so easy as far as their roof operation is concerned, even the Spyder!
And lastly, don't worry too much about upgrading the current Evora interior. Yes it's inferior to main-stream (i.e. rich) manufacturers like Porsche, but who cares? It's certainly good enough. Don't spend any development money there, work on the other parameters I've just mentioned instead.
I can't wait to see the Evora Roadster in the flesh. And I really hope it is good enough to tempt me...
