Here you go, straight from Lotus:
The Elise S (not USA), Elise R ('Elise' in USA) and Exige S continue with enhancements detailed in this bulletin.
Due to very low demand, the naturally aspirated Exige will be built only for certain markets and to special order. All cars will now be equipped with dual airbags and an engine start button, with the fascia structure featuring a new charcoal grey matt finish. Option packs have been reconfigured as detailed in recent sales communications, with a new Performance Pack option available for the Exige S, providing 243 PS.
A new alarm system uses a bespoke Lotus branded transmitter key and a new instrument pack features additional functionality. To meet new legislation, USA models are fitted with low tyre pressure monitoring, and all cars benefit from enhanced 'CAN bus' diagnostics, and a revised body colour range.
Also, the LED taillights are different units which don't require ballasts.
