2004 Lotus Exige

from Lotus Press After an absence from the place for 2 years, Lotus is the Lotus Exige – a car that at the revolutionised the … sports market despite being on for just over 18 months.

The generation Exige was introduced to the in early 2000 as a racecar for the Born out of the successful Lotus Elise racecar, which was throughout Europe with success in 2000 and 2001, the was hand built in low numbers for a few around the world.

The second Exige, unveiled as a world at the Geneva Motorshow in 2004, the same racecar-for-the-road philosophy and it to the driver of today.

With performance and handling, powered by an 1.8 litre VVTL-i (Variable Timing with Lift – engine producing a maximum output of 141 kW and 181 Nm of torque, the Exige to 100 km/h in 5.2 seconds and 160 km/h in seconds before reaching a top of 237 km/h.

Key to this phenomenal and handling is the total aerodynamic (which gives 41.2 kg of at 160 km/h – 19.3 kg: and 21.9 kg: rear) and light the latter made possible innovative engineering and clever indeed the Exige weighs in at 875 kg unladen with no options giving a power to weight of 161 kW/t and 4.56 kg/PS.

Being a true mid-engine the high tech engine is behind the cockpit and in front of the rear wheels. Power from the state-of-the-art 2ZZ-GE 1.8 4 cylinder 16-valve VVTL-i Valve Timing and Lift-Intelligent) linked to the C64 six-speed gearbox. The and gearbox combination, sourced Toyota, was chosen as the ideal for the Exige and perfect for the Lotus philosophies.

The lightweight engine, with a metal matrix composite cylinder block has been to a rigorous testing and development which, as part of Lotus’ key Elise programme, has involved half a million miles of in a wide range of extreme conditions from the Arctic to the Arizona and Nevada deserts and at in Colorado. This is in addition to world renowned development and programme that had already applied to the engine prior to the in the Exige.

To enable this leading engine to carry the driving DNA, a brand custom-engineered Lotus T4 engine system (EMS) has been The software for the EMS was designed and developed by specifically for the Exige. This management system and the extensive and validation work ensures the Exige has unique performance perfectly suited to the fast and track environments.

The engine system enables the VVTL-i to select the optimum camshaft lift and timing across the range of engine operating This interaction between the T4 EMS and the VVTL-i system gives the its optimum linear torque peaking at 181 Nm at 6800 rpm with the power of 141 kW at 7800 rpm.

The high revving engine is to a maximum engine speed of rpm on up changes (8000 rpm at steady The change from the low speed cam to the speed cam is controlled by the Lotus management system to achieve a transition, which will not the balance of the car. This occurs at around 6200 but can vary by a few hundred rpm depending on operating conditions.

The return switching from the speed to low speed cam occurs at rpm to extend the operating range of the on the high speed cam. helps the enthusiastic driver on the high output cam between changes.

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

Performance

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

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

Of course, the Exige isn’t all straight line performance. The is one of the quickest and safest cars A to B and around a circuit. Key to this performance is the aerodynamic package, creates 41.2 kg or downforce at 160 (19.3 kg front and 21.9 kg

The chassis

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

Cooling and air management

Lotus that some Exiges spend most of their being driven hard – this is exactly what it was for. Therefore the extra of heat from the brakes and needed to be managed. At the front of the are extra air ducts (for the oil coolers, which are part of the Pack). To keep the brakes under the very high that are expected with driving, brake ducts are just behind the front

Towards the rear of the Exige, side air intakes and a roof provide much needed air to around the engine bay.

All including the rear engine are covered in a lightweight steel

Design

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

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

The servo-assisted four-channel system monitors and distributes braking to each wheel as required, braking performance and minimising distance. Of course this tuned ABS system does not over from the skill of the but instead is initiated under conditions or when the driver is too on the brakes and would normally traction.

The specifically tuned point of the ABS system allows a driver to maximise the potential of the system through the utilisation of weight transfer as with a system. In the event of the driver more braking performance is possible, only then the system intervene to optimise the generated at the wheel. Therefore, on driving, even hard the driver would not expect to the Exige ABS system in operation.
