Date: 21.09.2011 Model: Introduction of the 12 model year Evora range Number: 2011/25 Non-USA Copy files should be maintained by: Service Manager Service Reception Supervisor Parts Manager TITLE Introduction of the Evora 12MY and S with IPS transmission (Supercharged with Intelligent Precision Shift). REASON To advise on new features and specifications to the 12 model year Evora range introduced during August production including higher specification variations, increased level of equipment, engine performance, suspension improvements and interior styling updates. IDENTIFICATION VIN character 7 indicates the engine specification. T = naturally aspirated (Manual or IPS). S = supercharged (Manual or S with IPS transmission). VIN character 10 identifies the model year: C indicates 2012 model year. ECU Engine Management Programs: Naturally Aspirated Manual and IPS Transmission = A132E0092. Supercharged Manual and IPS Transmission = A132E0096. TCU Transmission Control Unit Program: Naturally Aspirated IPS transmission = A132F0324. Supercharged with IPS transmission = A132F0223. ENGINE Induction The Evora S with IPS transmission uses the same Toyota 2GR-FE engine and 6 speed U660E automatic transmission unit as per the naturally aspirated model, but is now equipped with the same Harrop HTV1320 supercharger package and manifold adaptor as used in the manual supercharged versions. Both the S with IPS transmission and IPS Maximum continuous and transient engine speeds are now increased to 6,600 RPM and 6,800 RPM (non Sport mode) and raised to 7,000 RPM and 7,200 RPM in Sport mode, bringing them inline with the engine speeds of the manual transmission models. The Evora S with IPS transmission also requires the higher flow fuel injectors, uprated fuel pump and revised spark plugs as used on manual transmission supercharged model and using the same engine management program as the Evora S the net power output is increased to 345 bhp @ 7000 rpm with 400 Nm of torque @ 4500 rpm. The supercharger is driven via an increased length auxiliary drive belt with new bracket/idler assembly fitted to the engine to accommodate the revised configuration. As per the manual supercharged engine, the plenum/hose assembly within the induction system is not fitted as the supercharged engine is pressure charged whereas the naturally aspirated engine requires the intake plenum hose to act as a resonator. There are no engine revisions for 12MY naturally aspirated or supercharged manual transmission or naturally aspirated IPS transmission models.
Page 2 Exhaust A modified version of the exhaust silencer incorporating an exhaust silencer EP (Engine Protection) valve currently used on the 11MY Evora S will now be fitted to all 12MY vehicles as standard equipment regardless of the induction or transmission system fitted. The EP valve is controlled in both normal and sport mode as a function of engine speed and throttle pedal position, with different calibrations for each mode. When the vehicle is stationary the valve is closed in normal mode and open in sport mode. When the vehicle is moving the valve is predominately closed in normal mode and predominately open in sport mode. Exceptions to this are; -- In sport mode at low engine speeds and light throttles the valve is closed. -- In normal mode at full throttle the valve is open. For engine protection against high exhaust back pressure the valve is opened at engine speeds greater than 5500rpm and engine loads greater than 40 percent load irrespective of the selected mode. Please note: by depressing the sports button the operation parameters of the EP valve change, allowing it to be open more of the time. The sports button is predominantly intended for track use, utilising a sportier engine note and promoting a more enthusiastic driving experience. Exhaust silencers fitted to naturally aspirated models can be identified by their titanium or stainless steel twin tailpipe finishers. Supercharged models are fitted with a single ovular tailpipe finisher. Catalytic converters The main/under-floor catalytic converter is no longer fitted to non-federal vehicles but is replaced with a link pipe joining the exhaust downpipe to the silencer assembly. The removal of main catalytic converter reduces exhaust back pressure as well as enhancing engine noise characteristics. Cooling Engine cooling Oil cooling for both supercharged manual and IPS transmission vehicles has been rationalised with the fitment of only a single larger engine oil cooler mounted ahead of RH front wheel arch which feeds air from the outside of the vehicle via the intake and grille attached inset in the front bumper. Supercharged vehicles engine oil cooler circuit IPS transmission vehicle fluid cooler circuit sb135 Both the feed and return hoses are located to the RH side of the vehicle and connect into the same sandwich plate configuration located on the side of the engine block as the pre 12 model year supercharged vehicles.
Page 3 Transmission cooling Transmission fluid cooling for both supercharged and naturally aspirated IPS transmission vehicles has also been rationalised with the fitment of only a single larger transmission fluid oil cooler mounted ahead of LH front wheel arch. Air is fed from the outside of the vehicle via the intake and grille attached inset in the front bumper. Both the feed and return hoses are located to the LH side of the vehicle and connect into the same sandwich plate configuration mounted remotely to the rear bulkhead in the same manner as pre 12 model year IPS naturally aspirated vehicles. Brake and PAS (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. IPS transmission features The default return from manual gear selection back to automatic mode has increased from 10 to 20 seconds if a gear selection is not made using either paddle shifter (whilst in non sport mode). Neutral can also be selected from any gear by simultaneously pulling both steering wheel mounted paddle shifters towards the driver. Drive can also be selected from P, R or N by depressing the footbrake and pulling the + paddle shifter towards the driver. If vehicle road speed is over 1.2 mph (2km/h) the footbrake does not have to be depressed. Manual Transmission The standard ratio gearbox option is no longer available for naturally aspirated vehicles, and the sports ratio gearbox is now fitted as standard. Manual Transmission Oil Havoline Multigear MTF HD 75W-80 oil originally only supplied to the sports ratio gearbox when fitted to the Evora S has now been approved for all pre 12 model year manual model gearboxes. Body The body styling is 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.
