(from Lotus Press Release)
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
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.
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
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.
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
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
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
The servo-assisted four-channel system
individually monitors and distributes braking force to each wheel as
required, enhancing braking performance and minimising stopping
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.
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
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
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)!
