Lotus Exige (2005)

In order to protect the engine during the warm up phase, the maximum engine speed is limited to 6000 rpm and is restricted to the lower speed cam when the engine coolant temperature is below 70 °C.

A tell-tale red LED located in the centre of the instrument binnacle illuminates to indicate to the driver the optimum point to change gears.

The lightweight C64 six-speed gearbox (with an aluminium casing) is fitted with an all-new Lotus designed and developed shift operating mechanism. With the closest ratios and gearset afforded by the transmission, the gearbox offers a fast, precise and light gearshift, ensuring drivers have total control and flexibility to apply the power exactly as and when required.

A bespoke exhaust system with a bifurcated downpipe exits at the rear of the car through the centre of the rear diffuser.

Performance

The Lotus Exige is bestowed with the performance through lightweight expected of a Lotus with a power to weight ratio of 161 kW/t (4.56 kg/PS) and a 0-100 km/h sprint in 5.2 seconds and 0-160km/h in 13.2 seconds before reaching a top speed of 237 km/h.

Of course the Lotus Exige with its small 1.8 litre engine is Euro IV Emissions compliant and returns 8.8 l/100km on the combined cycle, as well as the very low figure of 208 g/km of CO2 emissions - figures usually unheard of for supercars.

Aerodynamics

Of course, the Lotus Exige isn't all about straight line performance. The Lotus Exige is one of the quickest and safest cars from A to B and around a circuit. Key to this incredible performance is the aerodynamic package, which creates 41.2 kg or downforce at 160 km/h (19.3 kg front and 21.9 kg rear). This downforce ratio between front (47%) and rear (53%) is of course balanced and remains constant at the speeds of which the Lotus Exige is capable.

This class leading aerodynamic package is provided through the aid of the following:

• Completely flat underside of the car - provided by the elegantly simple strong yet light extruded and bonded aluminium tub
• Black anodised rear diffuser which helps promote the "Venturi effect" underneath the car
• Deep front splitter which sits just 108 mm from the ground (giving just enough ramp angle clearance) whilst still maintaining the aerodynamic properties and of course the aggressive stance
• Fixed rear wing that is set at the optimum 11.5 degree angle for the best compromise between downforce and drag.

Lotus specific wheels and tyres

Lotus ride and handling engineers worked with Yokohama to develop a bespoke A048 tyre (rated W) and annotated with "LTS". These soft compound tyres were chosen to maximise grip and achieve the ride and handling targets set by Lotus.

Unique black lightweight eight-spoke wheels (16" front and 17" rear) complete the wheel and tyre package, as if the Lotus Exige has just come off the race track; in fact it probably just did - as Lotus envisages many customers of the Lotus Exige may take part in track days, which are becoming increasingly popular around the world.

The legendary chassis

Of course, the Lotus Exige is a Lotus and as such has a world leading chassis. Based around the revolutionary and award winning extruded and bonded aluminium tub, with lightweight steel rear subframe, used in the Lotus Elise 111R, the Lotus Exige uses stiffer Lotus Sport springs and dampers to provide minimum body roll and to exploit the exceptional level of aerodynamic performance and downforce, and the high levels of grip provided by the Yokohama A048 tyres.

Cooling and air management

Lotus expects that some Exiges will spend most of their time being driven hard - indeed this is exactly what it was conceived for. Therefore the extra levels of heat from the brakes and engine needed to be managed. At the front of the Lotus Exige are extra air ducts (for the optional oil coolers, which are part of the Performance Pack). To keep the brakes cool under the very high loads that are expected with hard driving, brake ducts are located just behind the front wheels. Towards the rear of the Lotus Exige, large side air intakes and a roof scoop, provide much needed air to circulate around the engine bay.

All grilles, including the rear engine cover are covered in a lightweight steel mesh.

Design

All Lotus products elegantly fuse form and function by combining the optimum engineered solution with a dynamic and elegant design that gives it a distinctive Lotus signature. The design project, undertaken by the Lotus Design Team lead by Russell Carr, took the core values of Lotus and the first generation Lotus Exige and applied them to the 2004 Lotus Exige. Signature racecar features such as the roof scoop, rear wing, deep front splitter and fast back roof have been carefully developed whilst new features such as the engine cover vents, side intakes and lightweight mesh grills and a unique graphic further differentiate the Lotus Exige from other products in the Lotus stable.

All the Lotus Exige body panels are made from strong, and lightweight GRC (Glass Reinforced Composite). Three new paint colours, in addition to the current Lotus range, are introduced solely for the Lotus Exige in 2004, these being Chrome Orange, Graphite Grey and Krypton Green.

Interior

Lightweight but strong composite sports seats hold the driver under the high g-forces that will be experienced on cornering, acceleration and braking. The small 320 mm offset steering wheel is perfectly suited to coaxing and guiding the Lotus Exige along some of the finest roads and around the most challenging of circuits. The lightweight extruded aluminium pedals are perfectly positioned for efficient heel and toeing - a technique that many drivers will wish to perfect to be able to exploit the performance of the car and drive it how it was meant to be driven.

Twin instrumentation dials show road speed and engine speed (up to 10,000 rpm) with the graphics and orange back lighting showing the key information clearly and efficiently.

A four speaker Blaupunkt stereo system with CD player is provided as standard along with a radio receiver wiring loom including a dipole aerial kit located in the front of the Lotus Exige.

Air conditioning, weighing in at a minimal 15 kg, is standard in some markets, where high ambient temperatures would otherwise prohibit the driving of such a high performing sports coupé. It is available as a cost option in all other markets.

Brakes - Track tuned ABS system to help out when needed!

The servo-assisted four-channel system individually monitors and distributes braking force to each wheel as required, enhancing braking performance and minimising stopping distance. Of course this track tuned ABS system does not take over from the skill of the driver but instead is initiated under panic conditions or when the driver is too heavy on the brakes and would normally break traction. The specifically tuned initiation point of the ABS system allows a skilled driver to maximise the potential of the braking system through the utilisation of forward weight transfer as with a non-ABS system. In the event of the driver demanding more braking performance than is possible, only then does the system intervene to optimise the force generated at the wheel. Therefore, on normal driving, even hard driving, the driver would not expect to feel the Lotus Exige ABS system in operation.

Equipment

Standard equipment for the Lotus Exige includes: Blaupunkt Lausanne radio CD-R/W player and Blaupunkt high performance front and rear speakers, auxiliary front driving lights and central door locking. For the Japanese market specifically, central door looking is only included as part of the optional Touring Pack. The Blaupunkt Lausanne radio CD-R/W player is not available in the Japanese market but a Blaupunkt BPV755 radio CD-RW player is available as an option (not part of the standard specification or the Touring Pack).

The Touring Pack (not available with the Performance Pack) provides a combination of options designed to increase comfort and convenience, while still maintaining the essence of a Lotus sports car. This pack contains:

• Electric windows
• Full carpet set with a lightweight aluminium passenger footrest
• Blaupunkt Woodstock DAB radio, CD-R/W and MP3 player (not available in Japan)
