2008 Lotus Eco Elise news, pictures, and information
Trackday Warrior Turns Eco Warrior
Lotus unveils the Eco Elise technology demonstrator at the British Motor Show, capitalising on great strides forward in green technology.The Eco Elise project promotes a different perspective on green, one which does not revolve solely around tailpipe CO2. This holistic approach is in keeping with the progressive Lotus culture, driving Lotus to become the worlds green automotive consultancy.
Sustainable materials, hemp, eco wool and sisal have been developed for body panels and trim and, combined with hi-tech water based paint solutions, showcase new affordable green technologies. The green credentials of the technology on show in the Eco Elise have been analysed throughout the lifecycle of the car.
A green gear change display has been integrated into the dashboard to promote greener driving as well as a weight reduction programme, illustrating the holistic approach taken. The energy expended to manufacture the car has been evaluated, working to the 3Rs - Reduce, Re-use and Recycle.
Mike Kimberley, CEO of Group Lotus plc commented 'This Eco Elise is a great example of the advanced and affordable green technologies Lotus is developing. We are at the cutting edge of environmental technology and are determined to push forward with our green agenda. The Lotus brand values of lightweight, fuel efficient, and high performance are more relevant today than they ever have been. We are keen to ensure that Lotus as a company and its products offer an ethical, green option that appeals to our customers'.
In keeping with the performance through light weight philosophy, the Eco Elise weighs 32 kg (70.5 lbs) less than the standard Elise S, which means that the efficient Elise S engine in the Eco Elise will give higher fuel economy figures and even better performance.
Dramatic improvements to the culture and operations at Lotus has rewarded the company with staggering reductions in energy (Electricity 14%, Gas 30%) and water (11%) consumed across the Hethel headquarters in 2007, compared to 2006. These advances have coincided with improvements in recycling, with 57% of waste product now being recycled.
The new green materials sourced for this car have been carefully studied to ensure that each technology used reduces the environmental impact of the vehicle. The life of the components has been analysed; during the production stage, in-use and at the end of the vehicles life. The technology used aims to offer lower emissions of both solvents and CO2 in the lifecycle of the vehicle, with reductions in energy consumed during manufacture.
The Eco Elise will be displayed in the Greener Driving Pavilion at the British International Motor Show from 23rd July until 3rd August. The project displays affordable green technology that is intended to be feasible and production viable in the near term future.
The Lotus Eco Elise in more detail
The project focuses on developments in:
• Sustainable materials
• Cleaner manufacturing processes
• Renewable energy generation
• Reducing carbon miles
• Efficient driving techniques
• Weight reduction
The renewable materials have been incorporated into the project, with hemp, eco wool and sisal providing natural, biodegradable engineering materials. Cleaner manufacturing processes have been sought, utilising the latest water based paint technology. Using this paint system saves energy and reduces emissions of solvents from the paint shop. Solar panels have been set into the hemp hard top to help power the electrical systems and give a means of renewable energy generation.
With the use of locally farmed hemp, the carbon miles to produce the Eco Elise are reduced, in keeping with the holistic approach to this vehicle. The Eco Elise puts an emphasis on efficient driving techniques by using an economy gear change display to improve fuel efficiency and promote greener driving. The car has undergone a weight reduction programme to add a little extra lightness, assisting in more economical, greener driving.
Sustainable materials
Sustainable hemp technical fabrics have been used as the primary constituent in the high quality A class composite body panels and spoiler. The renewable hemp has exceptional material properties that make for a very strong fibre. Historically hemp has been used in the manufacture of rope, illustrating the great strength of the material.
The hemp fibres have also been used in the manufacture of the lightweight Lotus designed seats. An additional benefit of using hemp is that it is a natural resource that requires relatively low energy to manufacture and absorbs CO2 whilst growing as a plant through natural photosynthesis. This hemp material is used with a polyester resin to form a hybrid composite, however it is hoped that a fully recyclable composite resin will be viable in the short-term future.
The Eco Elise seats are upholstered in a durable yet, biodegradable woolen fabric that has been given the EU Flower certificate to exemplify its environmental credentials. This new material is ethically produced and does not use any dyes or harmful processing. In fact the colour is created from the selection of sheep breeds used to produce the wool for the yarn, which increases the natural feel of the wool and reduces the processing of the cloth.
Sisal is a renewable crop that, like hemp, is used for its strong material properties. Sisal has been used for the carpets in the Eco Elise, as it is a tough, abrasion resistant material. The use of these materials illustrates the capability at Lotus of utilising new, advanced materials and the flexibility of the manufacturing facilities.
Cleaner manufacturing processes
Whilst improving the green credentials of the Lotus production facilities, the Lotus Paint Facility, in partnership with Du Pont has developed a totally water-based paint system. This paint solution includes primer, colour coat and lacquer, and it is the first time that it has been possible to hand spray a water based A class production paint finish.
In using this progressive water based technology, Lotus is able to achieve impressive savings in energy consumption due to the low cure temperature this paint requires. An additional benefit of this paint system is the reduction in emissions of solvents, all of which contribute to substantial cost savings for Lotus. This is a result of the unique collaboration with Du Pont in pushing forward low-volume paint spraying technology. This technology is anticipated to be available in production cars in the near future.
Renewable energy generation
The hemp hard top on the Eco Elise has two flexible solar panels neatly embedded in the roof, contributing power to the electrical systems and saving energy that would be drained from the engine.
The solar panels have been integrated into the hard top to illustrate the feasibility of applying this technology. This application shows the installation of solar panels into a composite A class panel with a double curvature. Using this technology on a greater number of panels would make it possible to provide more power, especially on a larger vehicle.
Reduction in carbon miles
The hemp fibres have been farmed in East Anglia, thus reducing the carbon miles incurred in the production of this Elise. Lotus Manufacturing has component manufacturing facilities and a paint facility at its headquarters in Hethel, Norfolk, with another manufacturing site a short distance away in Norwich. The company operates a carefully managed logistics system operating between sites to improve efficiency, reduce costs and carbon miles. This is a Kanban driven barcode system that has been adopted by key suppliers. The process also uses packaging that is recycled many times over to eliminate waste.
Efficient driving techniques
Lotus cars have red shift lights to help drivers extract the maximum performance from the engine. However for the Eco Elise, Lotus designed software has been developed to assist drivers in maximising the fuel efficiency of the engine. A green gear shift display has been integrated into the instrument panel to ensure that gears are changed at the optimum point to reduce emissions and save fuel.
Weight reduction
'Performance through light weight' is so synonymous with Lotus. The reduction in mass improves the handling and braking performance and also reduces the effort required to accelerate the car. The weight reduction philosophy has even extended to the audio system with an exceptionally lightweight stereo and speaker system from Alpine saving 1.5 kg (3.3 lbs). The system uses MP3/ iPod technology in a sleek modern design.
The Eco Elise uses special lightweight wheels that reduce the unsprung mass and contribute a weight saving of approximately 15.8 kg (34.8 lbs) over the already super light Elise wheels. The weight saving programme for the Eco Elise has resulted in a total saving of around 32 kg (70.5 lbs) over the feather light Elise S, which reduces the fuel required to drive the car.

Lotus, manufacturer of some of the world's greatest sports cars, has unveiled its highest-performance Elise model yet, the 1.8 litre 111R, equipped with a high-tech engine that allows it to sprint 0-60mph in a supercar-thrashing 4.9 seconds. Top speed is a certified 150mph.
The hand-assembled Elise 111R is the latest result of Lotus' work to offer a combination of award-winning design, power and accessibility for those looking to own a higher performance Lotus Elise as their everyday car.
In town, the new 111R is compact and powerful enough to dart in and out of traffic, whilst the soft-top and Blaupunkt sound system make it perfect for those hood down, music up cruises through the city. Out of town the 111R's race-bred pedigree comes into its own, with a steering and suspension set up that allows the driver to hug corners before punching out on to the straight.
To balance out the extra power under the bonnet, Lotus has developed an improved braking system. For the first time, track-tuned servo-assisted ABS brakes come as standard on a Lotus Elise, to make stopping the 111R as easy as accelerating.
Ansar Ali, general manager, Lotus Cars Ltd, said: 'The 111R is a car for those who demand the style and innovation of the Elise but want increased performance. Without doubt, the new engine and set-up deliver unrivalled handling and power in its class. With the 111R we hope we've delivered our most exciting, truest and addictive drive yet.'
As standard, the 111R comes with eight spoke alloys, half leather interior and central locking. Buyers can opt for the Touring Pack that includes a sound and thermal insulated soft-top, full leather trim and a DAB radio. Other options include air conditioning and hard top.
The 111R will go on sale on 26 January 2004 at an RSP of £27,995.
Background
The Lotus Elise is a true sportscar that has taken the world by storm, winning countless awards for handling, innovation and just pure fun. The Elise was first unveiled at the Frankfurt Motorshow in 1995 before entering production with first deliveries in August 1996. Since then, over 17,000 Elises have been built – some achievement for a car that was originally designed to be built in volumes of only 700 a year! The Elise was designed as a sportscar to be appreciated by real driving enthusiasts, fashion leaders and those who really appreciate technology and innovation.
The Lotus Elise introduced a range of technologies that revolutionised the automotive industry; such as a chassis made from extruded and bonded aluminium, a composite energy absorbing front crash structure and light weight composite body panels. The whole car weighed in at half the weight of an average family saloon. This light weight bestowed the car with phenomenal acceleration and handling. In 1996 the Lotus Elise was easily pulling 1g in steady state cornering with standard production tyres and a 0-100km/h (0-62mph) in 5.9 seconds.
In 2000 Lotus introduced the second generation Elise. This evolutionary car, arguably one of the most important cars in Lotus' fifty-two year history, added to the technology introduced on the Elise in 1996. It was a big stride forward, achieving the quality standards expected of a world leading sportscar manufacturer and globally respected engineering consultancy. This Elise introduced industry standard quality, much of it based upon the learning gained from working with Lotus' global motor industry partners.
All Lotus Elises are hand assembled by skilled craftsmen at Lotus' headquarters in Hethel, England. Each Elise takes about 100 man-hours to build and the final product is fine testament to the skills of Lotus.
The Interior
As soon as a driver sits behind the wheel of a Lotus, they instantly know that they are in something special. From the composite sports seats that hug the driver under the g-forces that are experienced on cornering, acceleration and braking, to the race designed steering wheel and the extruded aluminium pedals perfectly suited to both cruising as well as hard driving - the Elise is a car that invites to be driven.
The twin instrumentation dials show road speed and engine speed (for the 111R, now showing to 10,000rpm) and are updated for 2004 across the whole of the Elise range, with clearer graphics and orange back lighting which is proven to be easier on the eye. Links between the Elise and the track have always been strong, and the ambience of the facia and trim with the chassis tub sides provoke a strong sense of being seated in a racing derived but comfortable cockpit.
A four speaker Blaupunkt stereo system with CD player is provided as standard along with a radio receiver wiring loom including dipole aerial kit located in the front of the Elise 111R.
The legendary chassis…
During the early days of the original Elise development programme, Lotus searched for an appropriate and available chassis technology for its new lightweight sportscar. Unable to find a suitable technology, and unwilling to compromise, Lotus set out to change the rules. Lotus engineers looked outside the automotive industry and brought together aluminium extrusions and modern aerospace bonding techniques to produce a lightweight and exceptionally rigid structure.
The ground-breaking epoxy-bonded aluminium tub chassis, unveiled in September 1995 represented a breakthrough in sportscar technology.
The structure is an assembly of individually extruded lengths bonded together by epoxy resin adhesive, a world first in automobile manufacture. The adhesive used to bond the Lotus chassis achieves exceptional strength with the ability to absorb the most extreme loads, pressures and forces that it may encounter. Never before had a modern vehicle's chassis been bonded together.
The bonding of lap joints provides a superior joint to traditionally welded butted joints (with bonded joints, there is no distortion of the material's integrity at the join). Self-pierce rivets further increase the structural integrity through reducing material ‘peel' in the most severe of impacts.
The chassis received modifications in 2000, including lower, reinforced longitudinal sills to improve the access into the cockpit.
Now with the introduction of the VVTL-i power unit, further enhancements have been made to the rear of the chassis structure. Utilising experience gained from the development of advanced lightweight steel, a new highly efficient rear subframe offers increased strength. In keeping with Lotus' philosophy, this structure is an elegant integrated single solution for the engine cradle and improved suspension and exhaust silencer mounting points.
Ride and handling that sets the benchmark…
The aluminium chassis allows vehicle dynamics engineers at Lotus to continue to set standards by which all other sportscars are judged. Indeed, the Elise continues to build on the multi-award winning ride and handling for which it has become renowned the world over.
Lotus has taken a no-compromise approach in carrying over these philosophies to the Elise 111R. The development team has succeeded in creating a car that leaves the driver craving more time in the cockpit and more road on which to enjoy the thrill and engagement of each journey.
Run in parallel to Lotus' USA (Federal) Elise programme, the 111R faced a gruelling development programme exceeding 500,000 miles throughout 2003 that took the car across Europe and the USA. This has resulted in an exciting and progressive ride and handling package that integrates the constituents that make up the dynamics characteristics, tuning them to work in harmony with each other, the driver and the road.
For the Elise 111R, the Eibach coaxial coil springs and Bilstein high pressure monotube gas dampers have been retuned and optimised to maintain the Elise's trademark agility, body control and poise while improving the isolation of both smaller and larger impacts.
The unique Bridgestone Potenza RE040 tyres (175/55R16 front and 225/45R17 rear) have been carried over from the Lotus Elise and the Elise 111S. The Lotus Ride and Handling team have maximised the ability to hone the chassis and tyre characteristics to ensure that this latest and highest performing version of the Elise holds true to Lotus' values of peerless ride and handling and pure driving fun.
An ABS system like no other…
The servo-assisted four-channel system individually monitors and distributes braking force to each wheel as required, enhancing braking performance and minimising stopping distance.
However, Lotus has specifically tuned the initiation point to allow a skilled driver to maximise the potential of the braking system through the utilisation of forward weight transfer. 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.
Power-to-weight in abundance…
Lotus undertook a thorough and exhaustive evaluation of a wide range of state-of-the-art engines. Toyota's 2ZZ-GE 1.8 litre 4 cylinder 16-valve VVTL-i engine and C64 six-speed gearbox was chosen as an outstanding package, excellently suited to the Elise.
This engine has breath taking power and torque characteristics, and critically for a Lotus, is lightweight, featuring a compact metal matrix composite alloy cylinder block.
A bespoke exhaust system has been developed for the Elise 111R with the twin exhaust pipes exiting through the rear diffuser.
Lotus subjected the 2ZZ-GE to a rigorous testing and development programme covering a wide range of extreme climate conditions from the Arctic Circle to the Arizona and Nevada deserts, and at altitude in Colorado. Furthermore, the engine management system, bifurcated exhaust downpipe, and bespoke gearshift mechanism are designed and developed by Lotus, resulting in a power unit perfectly integrated with the Elise's chassis and dynamics.
Lotus has tuned the engine to suit the very essence of the Elise by employing a brand new, custom-engineered Lotus T4 engine management system (EMS). The software for the EMS was designed and developed by Lotus specifically for the Elise 111R. All calibration and validation work was undertaken solely by Lotus engineers, ensuring that the Elise performs as a true Lotus should.
Toyota's world-renowned VVTL-i system allows the engine management system the flexibility to select the optimum camshaft profile, lift and timing across the full range of engine operating conditions. This interaction between the Lotus T4 EMS and the VVTL-i system gives the Elise its optimum linear torque characteristics, peaking at 181Nm (133.5 lb.ft) @ 6800rpm coupled with the peak power of 192 PS (189hp, 141kW) at 7800rpm.
The all-aluminium lightweight Toyota C64 six-speed gearbox 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.
True to Colin Chapman's philosophy of performance through lightweight, the power density available from the Toyota power unit gives the Elise a staggering 223PS/tonne (220hp/tonne, 164kW/tonne) and a 0-100km/h sprint in 5.2 seconds (0-60mph in 4.9 seconds)!
Proof, if needed, that there actually is a substitute for 'cubic inches'!
Equipment
Standard equipment for the Elise 111R includes: half leather interior, sun visors, central door locking, Blaupunkt Lausanne radio CD-R/W player and Blaupunkt high performance front and rear speakers
Optional equipment includes a Touring Pack, which provides a combination of options designed to increase comfort and convenience, while still maintaining the essence of a Lotus sports car. This pack includes:
