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.

2-ELEVEN.A - CHASSIS

The 2-Eleven uses the basic chassis 'tub' of the Elise/Exige with minor revisions including;

Deletion of door hinge upright extrusions on each end of scuttle beam.

Full height side members (no cabin access cut down).

Revised pick up points for the roll over bar.

Addition of a body side attachment panel to the lower edge of each chassis rail sill extension.

The front crash structure is as Elise/Exige with minor fettling revisions, and the galvanised steel rear

subframe differs only in respect of incidental ﬁxings.

Roll-Over Bar

The tubular steel roll-over bar is substantially cross-braced, including provision for shoulder harness

anchorage, and features integral bracing struts to both front and rear. The feet of the main hoop are bolted to

tapping plates riveted into the top surface of the chassis side rails, with the front bracing struts locating against

the joint between the side rail top and scuttle cross-beam and secured by similar riveted tapping plates. The

rear bracing struts use a single ﬁxing bolt at each side to secure to the rear subframe.

The roll-over bar complies with FIA requirements for international motorsport, but note that any additions

or modiﬁcations to the 'bar may invalidate such compliance.

2-ELEVEN.B - BODY

On the 2-Eleven, the rear transom/bumper, body exterior side panels, ‘A’ panels, front splitter and splitter

end support panels and the single panel comprising the whole of the nose section and front wings, are secured

by threaded fasteners to permit easy removal for access to chassis or powertrain components, and allow simple

and economic accident repair. The composite body inner sides, together with the alloy sheet front and rear

cabin bulkheads and rear scuttle panel, are secured with an elastomeric adhesive.
