Lotus 2-Eleven (road spec.)

2-ELEVEN.# - CONCEPT & OVERVIEW

In March 2007, Lotus announced the Lotus 2-Eleven (255 PS) designed for the motorsport enthusiast, and 

aiming to provide a high fun factor from a lightweight, high performance, distinctively styled vehicle, suitable 

as a basis for various sporting disciplines, as well as offering U.K. customers the option of a unique road going 

experience.  The cars to be produced in small numbers for the U.K. and certain overeas territories tailored to 

customer specification from an extensive options list.

The running gear is based on the Exige S, and shares that car's basic chassis and supercharged powertrain 

componentry, but uses a new chargecooler arrangement and peripheral systems.  Unique engine programming 

is used in conjunction with 4 high flow fuel injectors as used on Exige Cup cars.  The open top lightweight body 

is designed to be amenable to economic accident repair and is supplemented by an FIA compliant roll over 

bar, and strut mounted rear aerofoil acting directly onto the rear subframe.  Options include a race specifica-

tion carbon fibre adjustable rear aerofoil combined with an enlarged front splitter for enhanced aerodynamic 

balanced downforce, and Ohlins fully adjustable spring/damper units with remote reservoirs.   

This supplement describes the unique features of the 2-Eleven, and refers to other models where com-

ponentry is shared.
