Lotus CEO, Dany Bahar, said the new model would get 147 changes, all of which will be aimed at improving the overall quality of the Evora. Bahar said in a recent Auto Express report, the "priority is to improve the quality, to give the car a soul".
The changes are likely to include a new interior with higher quality finishes and materials, a new exhaust creating a distinct sports car sound, and a slicker transmission.
Other changes include the introduction of new showroom variants. Lotus is planning a cabriolet version, which will share its roof mechanism technology with the upcoming Espirt carbrio, as well as a focused high-performance version.
The high-end sports version will feature a supercharged 3.5-litre V6 producing around 298kW of power. Reports say the model will have a similar focus as the Lotus Evora GT race car, only more suitable for the road.
In October, Lotus is also planning on unveiling a working hybrid Evora concept which will use two electric motors and a 1.2-litre three-cylinder hybrid powertrain. The ultra-fuel efficient model is set for release sometime in 2013.
