The body – an evolution
| ||Vital Stats|
The new 2011 model year Elise range is on sale now and will be in showrooms from April 2010. The body of the new 2011 model year Elise is an evolution of the iconic Elise design, retaining the character and style, while offering a more planted, purposeful stance and a pure, contemporary look that links it to the Evora. As wîth all Lotus product the design is an exciting blend of dramatic style and functional efficiency
The new Elise body has a fresh sculptured front, including a new bumper, front clam and access panel that combine to give the Elise a wider look wîth more road presence.
At the rear of the car the new engine has been encased by a distinctive 'twin-spine' engine cover whilst lower down a more aggressive diffuser is tightly wrapped by an elegant new bumper design that now includes the rear licence plate.New headlamp units wîth distinctively sculptured LED lighting guides
(incorporating daytime running lamps and direction indicators) give a contemporary twist to this classic design. Elsewhere, the signature, Lotus 'mouth' and familiar sculptured forms have been sensitively refined to give a crisper, more dynamic look. The repositioning of lamp functions has enabled the creation of broad clean surface between the fenders which combines wîth sleek corner intakes and prominent splitter detail to give a broader more planted stance.
The theme of purity is carried through to the cooling apertures that are efficiently finished wîth a new lightweight aluminium mesh that gives the car a classically sporting character.
The rear boot is now opened from the cockpit rather than via a separate key operation. The high quality feel of the Elise is continued throughout the car wîth the Elise graphic incorporated into the new side LED direction indicators, like those on the Evora.
The driving position, from the perfectly positioned pedals and §teering wheel, to the comfortable and supportive seats wîth ProBax** technology means that, like all Lotus cars, the driver becomes part of the car rather than being just a passenger.
With the sleek new body the aerodynamics have improved giving a reduction in the coefficient of drag of 4%.
Finally, a choice of two beautiful, light weight wheel designs are available; an incredibly light forged wheel and a new cast wheel completes the picture for this sensitive update of a Lotus Icon.Additional changes to the 2011 model year Lotus Elise
The new 2011 model year Elise has a number of additional changes and improvements, wîth the installation of a new advanced 1.6 litre Valvematic engine meeting EÚRO 5 regulations. This new engine is 200cc smaller than the outgoing Elise S model and produces similar power (136 PS, 100 kW, 134 hp at 6800 rpm) wîth maximum torque of 160 Nm, 118 lbft at 4400 rpm, but offers a significant improvement to fuel economy of over 23%, to 6.14 litres / 100km (46 mpg)* and a reduction in CO2 emission by more than 13%*. This provides the new Lotus Elise wîth the lowest CO2 per performance for any gasoline high performance sportscar in the world. This high technology engine is mated to a new 6-speed manual gearbox, providing closer and more performance orientated ratios than the outgoing 5 speed box.
The 1.6 litre engine is controlled via the bespoke Lotus T6 engine management system. Cruise control is available on the Elise for the first time wîth the controls present on a stalk located to the left of the §teering column.
New cast wheels have been designed specifically for the Elise and the new optional forged wheels weigh just 29.26 kg per set, 2.14 kg lighter than a set of lightweight cast versions. Both are available in silver or black colour.
Dany Bahar, Chief Executive of Group Lotus said, 'The Lotus Elise revolutionised the sportscar when it was launched 14 years ago and now the Lotus Elise has become greener, giving drivers access to class leading performance wîth less guilt.'
Donato Coco, Director of Design said, 'The Elise is an iconic sportscar and it was important that we did not complicate its design, so we made the car more pure in its look, improved the aerodynamics, and gave it a more contemporary look wîth high quality detailing.'
Paul Newsome, Director of Lotus Product Engineering said, 'We are always lòòking at ways of keeping the Elise ahead of its peers and for the 2011 model year we have improved efficiency without losing the innate fun that has made the Elise legendary.'
Andreas Prillmann, Chief Commercial Officer for Lotus Cars said, 'In its 14 years of production the Elise has accounted for 32% of all the 61 years of Lotus production, illustrating how significant to the brand and well loved it is. The 2011 model year Elise is greener, purer and more desirable, making it even more relevant to today's marketplace. The new Elise underlines Lotus' reputation as one of the most innovative sports car manufacturers in the world.'PerformanceLotus Elise

The Elise - the entry modelEngine
The Lotus Elise introduces the new 1598 cm3, 1ZR-FAE engine, provided by Toyota. The key to this engine's performance and efficiency is the Valvematic system (a variable valve lift mechanism), which is combined wîth the dual VVT-i (Variable Valve Timing-intelligent). The engine continuously controls intake valve opening/closing timing and the intake valve lift to vary the volume of the intake airflow, giving significant improvements in efficiency and fuel economy. This ensures optimal performance based on the engines operational condition, thus helping the Elise achieve both high fuel efficiency and high performance.
First of all, the maximum power output is achieved at near maximum revs (engine speed) of 6800 rpm and maximum torque (a respectable 160 Nm, 118 lb.ft) is reached at 4400 rpm. This gives a good combination of mid range pull but also encourages the driver to rev the engine to the maximum permitted engine speed of 7000 rpm (transient rev limit). Like all Elise sportscars, there are three shift up lights, on the binnacle cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that the driver is almost on the rev limiter so time to change up a gear!
The height of the engine cover has been raised by 34mm to accommodate the taller 1ZR engine compared to the previous 1ZZ engine from the outgoing model due, in part, to the additional Valvematic technology included on the new engine. This has given Lotus engineers an opportunity to subtly redesign the rear engine cover to match the design theme from the front and rear of the car.Chassis
The Lotus Elise is built around the revolutionary and award winning extruded and bonded aluminium chassis, wîth a lightweight steel rear subframe. The chassis weighs 68 kg (150 lbs) and has a stiffness of 9,800 Nm per degree, giving a high level of control of the suspension. At the rear, and also acting as a rear energy absorbing crash structure, a lightweight steel subframe carries the engine and gearbox. At the front, the radiator and key ancillaries are mounted into a high tech composite energy absorbing crash structure that is both lightweight, compact and over three times more energy absorbing than the equivalent steel structure.Ride and handling
The legendary Lotus ride and handling gives a superb high performance, sporty drive, combined wîth a compliant ride and progressive on limit handling, it makes the Elise a car that demands to be driven. The entry level Lotus Elise weighs 876 kg, making it one of the lightest fully homologated sportscars in the world. This low weight translates into efficient performance wîth minimal environmental impact in terms of emissions and fuel consumption. The efficiency of the Elise structure means that the 136 PS (100 kW, 134 hp) delivers phenomenal performance. Few cars can match the delicacy and accuracy of the §teering, throttle and brakes of the Elise and all of these factors contribute to the excellent driving experience of the Elise.Safety
The Elise has high performance AP Racing callipers at the front and Brembo callipers at the rear linked to 282 mm vented and cross-drilled cast iron discs to give excellent stopping power. The Elise comes as standard wîth a track tuned ABS system that is designed to be unobtrusive under normal driving conditions. This system is designed to be used on track and has a high threshold, only intervening in emergencies. The ABS system is linked to a lightweight pedal box wîth steel pedal arms and extruded aluminium pads. This unit also has an electronic (drive-by-wire) throttle for quick, smooth and more linear engine response. The impressive braking coupled wîth excellent handling gives good primary safety and the composite front crash structure and rear crash protection offers efficient secondary safety. Driver and passenger airbags and pre-tensioning seatbelt are standard on all Elise models.Prices will be announced in March 2010.
*The Lotus Elise is currently undergoing EC Whole Vehicle Type Approval and official fuel consumption and CO2 emissions figures, plus performance figures are not yet available. The official figures for fuel consumption and CO2 emissions and performance will be published on Group Lotus plc's web site as soon as they become available (www.grouplotus.com) or may be obtained from the PR Department, Lotus Cars Limited, Potash Lane, Hethel, Norfolk, NR14 8EZ, ÚK.**'ProBax™' seats
Introduced for 2006 Model Year Lotus Exige and Elise cars, ProBax™ seats are designed by Lotus and specifically adapted and developed by NuBax. ProBax™ seats help to significantly improve the postural position of the occupant's spine whilst seated compared to similar seat shells without ProBax technology. This not only results in an improved level of comfort, but also has significant medical benefits - maintaining a natural curvature of the spine, and markedly improving the body's blood flow. Increased blood flow has been shown to enhance response times, raise alertness levels and reduce the onset of muscle fatigue. Tests on Lotus seats, wîth the new ProBax™ technology, have shown an improvement in blood flow of up to thirty per cent over the pre-2006 Model Year Lotus seat. About Lotus

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 wîth 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 lòòking 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, wîth a §teering 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 wîth 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 wîth 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 ; 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 wîth phenomenal acceleration and handling. In 1996 the Lotus Elise was easily pulling 1g in steady state cornering wîth 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 standard quality, much of it based upon the learning gained from working wîth Lotus' global motor 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 §teering 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, wîth 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 wîth the chassis tub sides provoke a strong sense of being seated in a racing derived but comfortable cockpit.
A four speaker Blaupunkt stereo system wîth CD player is provided as standard along wîth 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. Únable to find a suitable technology, and unwilling to compromise, Lotus set out to change the rules. Lotus engineers looked outside the automotive 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 wîth 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 wîth the introduction of the VVTL-i power unit, further enhancements have been made to the rear of the chassis structure. Útilising experience gained from the development of advanced lightweight steel, a new highly efficient rear subframe offers increased strength. In keeping wîth 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' ÚSA (Federal) Elise programme, the 111R faced a gruelling development programme exceeding 500,000 miles throughout 2003 that took the car across Europe and the ÚSA. 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 wîth 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 wîth 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 wîth 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 wîth the peak power of 192 PS (189hp, 141kW) at 7800rpm.
The all-aluminium lightweight Toyota C64 six-speed gearbox is fitted wîth 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:
Auxiliary front driving lights, a choice of either full leather or Alcantara trim, a soft-top wîth sound and thermal insulation, electric windows, an upgraded Blaupunkt Woodstock DAB radio, CD-R/W and MP3 player, interior stowage net, sound insulation, and full carpet wîth a lightweight aluminium passenger footrest.
