Lotus Service Notes Introduction
VEHICLE IDENTIFICATION NUMBER & ENGINE NUMBER
The Vehicle Identification Number (V.I.N.) is a unique 17-digit number used to identify the car for licencing, warranty, spares ordering and administrative purposes.
The chassis frame is stamped with the V.I.N. on the crossmember beneath the driver’s seat, accessible inside the cabin with the seat slid fully rearwards. Pull back a flap in the carpet to view. The number is also printed on a label stuck to the vertical face of the fuel tank bay, below the front edge of the right hand rear seat cushion or luggage shelf. Pull back a flap in the carpet to view.
It is essential that the complete V.I.N. is quoted in any correspondence concerning the car, or when order ing spare parts.
Engine NumberThe 6-digit engine serial number is stamped on the LH rear flange of the cylinder block, alongside the
clutch housing jointface, and is viewable only from beneath after removal of the engine undertray. The number is repeated on a bar code label applied to the front face of the left hand cylinder head, which may be viewed from above using a mirror.
The full V.I.N. should always be quoted with any vehicle enquiries, together with the engine number if the query is engine related. Factory records are filed against V.I.N., and specification change points are identified by V.I.N. or engine number.
The V.I.N. comprises 17 characters, coded in accordance with European Economic Community (EEC) direc-tives, and with those of the National Highway Traffic Safety Association (NHTSA). For change point identification in Service Notes, Service Bulletins and Service Parts Lists, typically, only characters 10 (model year), and 14 to 17 (serial number) will be quoted. For example 'A 1234' being 2010 model year, serial number 1234.
Note that the serial number sequence re-starts at 0001 for each model year, and is shared with all other Lotus model families (e.g. Elise and Exige).

Rear undertray: Additional integral underside air scoop used in conjunction with existing NACA ducts. New diffuser panel to accommodate distinctive diffuser finisher and tri-oval tailpipe silencer. Addition of the ‘S’ logo to the existing Evora rear bumper badge.Brakes:Discs: Cross drilled brake discs and black painted callipers fitted to supercharged models as standard.SuspensionFront lower wishbone rear bush stiffness by 10%. The bush change achieved a 12% reduction in Camber Com-pliance (less camber loss whilst cornering) and a 22% increase in lateral stiffness at the Tyre Contact Patch. The static geometry settings are also revised.Rear suspension: Both upper and lower wishbone bush stiffness’s are increased by 10%, and the rear anti-roll bar is increased by 0.5mm in diameter. The fitting of the revised components achieve a 19% reduction in Camber Compliance (less camber loss whilst cornering), a 32% increase in lateral stiffness at the Tyre Contact Patch and a 1.5% increase in rear roll stiffness. The static geometry settings are also revised.Optional Wheels: Front 19” Rear 20” Forged alloy Diamond Cut “Design” fitted with Bespoke Pirelli P-Zero Corsa tyres with specially formulated compound which can be identified with an LS marking on sidewallTransmissionSports Ratio Gearbox fitted as standard. Lightweight low inertia flywheel allowing the engine to climb up the rev range more freely therefore making the engine feel sportier when compared to the naturally aspirated engine.Clutch: New lighter inertia, heavy duty clutch system fitted to manage the 400Nm torque produced by the su-percharged engine, consisting of a new clutch cover with revised finger ratios and an upgraded centre plate.Havoline Multigear MTF HD 75W-80 for Evora S sports ratio gearbox.

Lotus Service Notes Introduction
Introduction of the Evora IPS (Intelligent Precision Shift) Non USA - March 2011Introduced from ‘11MY VIN BH_11746Same vin characters as naturally aspirated Evora
The Evora IPS utilises the Toyota 6 speed U660E conventional fluid filled automatic transmission and torque converter assembly.
The Lotus IPS transmission system allows the driver to switch between conventional 6 speed automatic drive to manual paddle shift mode with the option of ‘Sport’ mode producing quicker and more pronounced gear shifts as well as optimising shift points for performance.
The same front mounted air/oil coolers used on the Evora ‘S’ for engine oil cooling are now used to coolthe transmission fluid with the sandwich plate/thermostat assembly now mounted remotely to the rearbulkhead.
See TSB 2011/13 for further information
Introduction of the ‘12 model year Evora range and S with IPS transmission (Supercharged with Intelligent Precision Shift). (Non USA) – August 2011. VIN character 10 = C Serial number restarts at 0001, common to all. VIN character 7 indicates the engine specification. T = naturally aspirated (Manual or IPS). S = supercharged (Manual or S with IPS transmission) variants.Body styling: Unchanged with the following exceptions: Door mirror covers: All supercharged models will retain Phantom Black painted covers (Lotus code C123 Cromax Pro painting system) as standard. Exterior door handles: The chrome option has been deleted with only body coloured options available. Diffuser panel: The diffuser panel fitted to the supercharged manual vehicle is also fitted to the S with IPS transmission option to accommodate distinctive diffuser finisher and tri-oval tailpipe silencer. Badges: The ‘S’ logo will also be applied to the rear bumper on the S with IPS transmission option. Front bumper: To accommodate the rationalisation of the engine and transmission oil cooler arrangements, the side intake apertures on the front bumper are revised to accept new front grilles and inlet ducts. The grilles are now bolted to the bumper with the corresponding LH/RH ducts located behind them being closed off if an oil cooler is not required on that side. Rear lamp bezels: Supercharged vehicles will have black bezels; naturally aspirated vehicles will continue to use the existing chrome versions.Seats: New leather seat colours are available dependant on interior pack option selected (Base, Executive Premium or Sports Premium). Ebony black, Ivory white, Venom red, Cognac brown, Imperial blue, Cocoa brown, Ash brown. Rear seats and relevant interior trims are coloured to match.Interior trims: A new colour (dark grey) introduced in addition to the current grey option, beige colour trim is deleted for ‘12 model year. Specific interior trims are coloured black to denote ‘Supercharged’ variant.In Car Entertainment: For specific markets the Alpine IVA-W520R 2 DIN Mobile Media Station is replaced with the Pioneer AVIC-930BT 2 DIN head unit. Exhaust: An exhaust silencer incorporating an EP (Engine Protection) valve is now be fitted to all ‘12MY vehicles as standard equipment. Catalytic converters: The main/under-floor catalytic converter is deleted and replaced with a link pipe. Engine cooling: Oil cooling for both supercharged manual and IPS transmission vehicles is rationalised with the fitment of only a single larger engine oil cooler mounted ahead of RH front wheelarch. Transmission fluid cooling: Both supercharged and naturally aspirated IPS transmission vehicles is also rationalised with the fitment of a single larger transmission fluid oil cooler mounted ahead of LH front wheel arch.Brake and Power Assisted Steering pipes: fitted to the RH have been revised to allow for the fitment of an additional cooler hose and revised cooler arrangement.Manual Transmission: The standard ratio gearbox option is deleted for naturally aspirated vehicles, and the sports ratio gearbox is now fitted as standard.Brake Discs: Cross drilled brake discs fitted to all supercharged models as standard equipment. Brake Callipers: Red painted callipers replace the black coloured option and are fitted as standard to all supercharged vehicles or included in the ‘Sports Pack’ option for naturally aspirated vehicles.

LIFTING POINTS
When using a lifting jack or hoist, care must be taken to position the device only beneath the areas shown in the illustration. Each designated point uses a ribbed alloy reinforcement pad integral with the main chassis structure. Use a suitable rubber pad to provide additional protection from surface damage:
A; Identified by an adjacent blue sticker. Beneath the front ends of the chassis main siderails, just behind the rear edge of the front undertray.
B; Identified by an adjacent blue sticker. Beneath each end of the fuel tank bay rear crossmember, just ahead of the front edge of the engine bay undertray.
If using a single jack for wheel changing purposes, a single rear lifting point (B) may be used to raise both wheels on that side of the car. With the limited vision available under these circumstances, extra care must be taken to position the jack correctly.
Note that in order fully to exploit the benefits of light weight, and to maximise stowage space, the Evora has no provision for spare wheel carriage or lifting jack. A temporary puncture recovery facility is provided in the form of a tyre inflator aerosol stowed in the right hand side of the boot.

UNDERTRAYS/DIFFUSER
For certain service operations, it may by necessary to remove the front and rear undertrays and/or diffuser panel. The panels contribute to the aerodynamic performance of the car and also help to keep the engine bay clean. Do not run the car without the panels fitted.
Front Undertray
The undertray is fixed in place to various vehicle components, to maintain a flat and level underside profile; spacers of various thicknesses are added between the undertray and its mounting points.
Fixing Points
A. Rear of front subframe: retained with 4 M8x20 mm screws running left to right along the rear of the front subframe and torqued to 12Nm. Each screw passes through a 4.6mm thick spacer and into a rivnuts fitted into the subframe.
L/H & R/H suspension wishbone rear mounting:B. retained with 1 M8x20 mm screw on either mount and torqued to 12Nm. Each screw passes through a 3mm thick spacer into rivnuts fitted into the mounts.
