Lotus Sport Exige 240R

EXIGE S/C.# - CONCEPT & OVERVIEW

In February 2005, Lotus announced  the Lotus Sport Exige 240R (243 bhp) to provide discerning customers 

with an exclusive very high performance derivative of the Exige, to be built in a global limited edition of 50 units.  

The cars to be produced to customer order as post registration official factory conversions of the '05 Exige by 

the Lotus Sport workshops at Hethel, and available for the U.K. and certain overseas territories where regula-

tions allow.  In November 2005, Lotus Sport commenced build of a limited number of Exige Cup 240 cars in 

road or race specification for selected markets, and differing in detail to the 240R.  Then in January 2006, an 

official production version of the supercharged car, Exige S, was introduced with a simplified specification. 

The performance of the standard Exige is uprated by the fitment of a Magnuson supercharger belt driven 

from the crankshaft, feeding through an air/air chargecooler into a new plenum/intake manifold, and featuring a 

supercharger integral by-pass valve.  The 240R engine uses a mechanical throttle and a 5th injector mounted 

in the intake manifold plenum, whereas the '06 M.Y. Cup cars use an electronic throttle, larger port injectors 

and no 5th injector, and the Exige S utilises standard injectors.

Chassis dynamics on 240R and Cup cars are uprated by the fitment of Ohlins 2-way adjustable dampers, 

with adjustable spring platforms for the uprated springs, and new lightweight forged 5-spoke roadwheels of 

slightly wider section to accommodate optional track use only slick tyres.  

This supplement describes the features of the supercharged variants which differ from the standard '05 

Exige model.  For information on any subject matter not included here, refer to the main manual.

EXIGE S/C.B - BODY

Exterior

All 50 of the 240R cars are finished in high metallic content paint in either Sport Yellow or Sport Black, 

reflecting the brand colour scheme of Lotus Sport.  Yellow cars are complemented by black roadwheels, and 

black cars with high power silver wheels.

A Lotus Sport 240R decal is applied to the RH side of the rear transom.

Paint Codes:  

Sport Yellow: Lotus code B112  Du Pont code X3454

Sport Black: Lotus code B111  Du Pont code X3453

240 Cup and Exige S models were offered in the complete range of colours with the front splitter, side 

intake scoops and the rear aerofoil (excluding support struts) finished in body colour rather than satin black.  

Exige S cars feature an 'Exige S' decal on the rear trabnsom, and an 'S' decal on each fron quarter panel.  Both 

decals available in grey or silver dependent on body colour.

The chargecooler air intake scoop on the roof of Exige S models is fitted with an enlargement funnel mouth 

(without grille) for increased airflow and enhanced chargecooler efficiency. 

Interior

Each Lotus Sport Exige 240R is individually numbered from 001 to 050, and identified by a Lotus Sport 

build plate styled after those used by Team Lotus for the Formula One cars.  The plate is riveted to the chassis 

main side rail on the passenger side, and is engraved with the unique Limited Edition number.

The 240R features black leather sports seats embroidered on the head restraints with Exige branding in 

yellow, with further Lotus Sport yellow highlights on the seat sides, door trim inserts, gear lever gaiter and park-

ing brake lever gaiter.  Cup cars use black leather/suede/carbon effect trim with '06 M.Y. Probax sports seats.

240R and Cup cars are fitted with four point seat belt harnesses, with the shoulder straps anchored to a 

seat belt mounting frame (roll hoop) cross bar.  The roll hoop and back stays on these cars are manufactured 

in T45 steel to allow easy conversion to U.K. motorsport MSA approval by the addition of an 'A' frame and 

diagonal brace.   

All 240Rs are equipped with air conditioning, but is optional on other models.
