PRESS RELEASE
Lotus Eco Elise
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 world's 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 3R's - 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 vehicle's 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 woollen
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.
