While 15kg might not sound like much, the Exige S only weighed 1176kg to begin with, and its new 1161kg starting weight is combined with 42kg of aerodynamic downforce at 160km/h.
Weight has been stripped from the battery, centre console, doors and seats, but Lotus hasn’t skimped on the upmarket touches.
The seats are trimmed in leather with colour-coded stitching or Alcantara as a no-cost option, and the centre console is the same colour as the body.
Exterior colours include Exige Orange, Metallic White or Metallic Yellow with 'Exige S CR' decals, while Matt Black is available for an extra £2,000 for UK customers.
The same ‘Exige S CR' decal also adorns the stereo blanking plate, but Lotus can fit an audio system instead for an extra £1,200.
Other options include a lightweight brake package and air conditioning.
For the enthusiast, a sports steering wheel is standard and Lotus’ selectable ‘Drive, Sport and Race’ traction control system is also fitted.
Beyond the diet, Lotus says it has applied the Club Racer ‘principals’ to the new model, resulting in the “benchmark for handling and pure driving experience” among its current line-up.
The changes are all track-focused, and don’t affect the ‘regular’ S’s 0-100km/h time of 4.0 seconds or its 274km/h top speed.
Power still comes from a supercharged 3.5 litre V6 engine producing257kW/400Nm, while returning an official fuel figure of 10.1 l/100km.
The 2015 Lotus Exige S Club Racer is only available as a coupe, priced from £56,900 (AU$107,948) for UK customers.
The regular Exige S coupe in Australia starts from AU$132,990 plus on-roads with the manual transmission.
Pricing for the S Club Racer will be announced closer to launch, with the new model expected to arrive in Australia late this year or early 2016.
