Yes you will fit and will be comfortable too. Also your best answer is to either go to a dealership and sit in one or maybe go to a local lotus meet and someone can maybe let you in one. The rule is if you sit in a persons evora you must wear a monocle, top hat and traditional tux...pictures are required.
I'm 6'4" - 220lbs and I drive an Elise. the evora is larger than the elise and not as hard to get into. I'm sure you'd be fine. it all depends if you have long legs, or a long torso. I'm all legs so I fit just fine in my elise.
The Evora has custom made Recaro CS sport seats. The door sill is still pretty wide, but it is a lot easier to get into than an Elise. I am 6'2, normally abut 185 (right now like 150) and I fit in either car, but Evora seats are quite a bit more comfortable. I wish there was an Evora roadster available.
