The British sports car firm has already confirmed it will show a lighter, more powerful version the Evora in Geneva, a move that could further strengthen its recent positive turnaround.
These latest spy pictures reveal that styling changes will be relatively minor and are focused mainly on reprofiled front and rear bumpers. A more prominent front grille can also be seen. Inside, Lotus looks set to keep its twin-dial cockpit layout, although minor improvements to materials and trim are expected.
Lotus chief executive Jean-Marc Gales told Autocar last year that the 2015 Evora will have about 15 per cent more power and less weight than the outgoing model, as well as the styling changes seen here.
The current Evora is powered by a 3.5-litre V6 engine, which is available in both naturally aspirated and supercharged forms. The standard car offers 276bhp and 258lb ft of torque, rising to 345bhp in the Evora S.
