Lotus OMNIVORE Engine Powers Up with Gas or Alcohol Equally

Lotus Engineering, the world renowned automotive consultancy division of Lotus announces a collaboration with Queen’s University Belfast and Jaguar Cars Ltd to develop an engine which maximises fuel efficiency when running on renewable fuels.

The OMNIVORE concept will employ novel engine architecture to achieve a high thermal efficiency when fuelled on any alcohols or gasoline.

The project is sponsored by Defra (Department for the Environment and Rural Affairs) and the DOE NI (Department of the Environment Northern Ireland) through the Renewable Materials LINK Programme. Lotus Engineering is currently undertaking a design study and the build of a single cylinder research engine for completion in January 2009. Vehicle modelling will validate the reduction in vehicle CO2 emissions. Queen’s University of Belfast’s School of Mechanical and Aerospace Engineering will be adding its world leading expertise in engine simulation, with Jaguar Cars Ltd a consultative partner at all stages of development.

This engine design is expected to significantly increase fuel efficiency for sustainable bio alcohol fuels. The architecture features an innovative variable compression ratio system and uses a two-stroke operating cycle with direct fuel injection. The OMNIVORE engine will be ideally suited to flex-fuel operation with a higher degree of optimisation than is possible with existing architectures.

Mike Kimberley, Chief Executive Officer of Group Lotus Plc said: “The automotive industry is now focusing on its environmental obligations to reduce CO2 emissions and improve efficiencies and we are seeing the high technology capabilities of Lotus Engineering being in strong demand. Not only does our brand value of ‘performance through light weight’ fit perfectly with the necessary direction of the industry to produce lighter, more efficient vehicles, we are also working on all aspects of future fuels, investigating alternative powertrains to accommodate alcohol fuels as they enter the market.”

Kimberley continues: “Alcohols possess superior combustion characteristics to gasoline which allow greater optimisation. Taking full advantage of the benefits of sustainable bio alcohols will ensure a greater percentage of vehicle miles will be travelled using renewable fuels. We are delighted with the investment from DEFRA which will assist this partnership in taking forward research development and the demonstration of this environmentally conscious transport solution.”

The OMNIVORE programme complements the recently unveiled Lotus Exige 270E Tri-fuel as part of Lotus’ research to understand the complex combustion process involved in running on mixtures of alcohol fuels and gasoline, which will be important for a successful transition from today’s fuels to the sustainable, synthetic fuels of the future.

Geraint Castleton-White, Head of Powertrain at Lotus Engineering said: “The requirement to operate on gasoline in today’s flex-fuel engines limits their thermal efficiency when operating on alcohol fuels. However, the physical and chemical properties of alcohols, when compared to gasoline, provide the potential for higher thermal efficiency operation to be achieved. This singlecylinder research engine will investigate a highly thermal efficient combustion system that optimises engine performance to fully exploit the properties of both gasoline and alcohol fuels and maximise efficiency.”

Lotus sounds off Hybrids with "Safe & Sound" System

Lotus Engineering, the world renowned automotive consultancy division of Lotus, has developed technologies to synthesise external sound on electric and hybrid vehicles to counteract the growing concern these ‘quiet’ vehicles pose to pedestrians and cyclists.

A simulation of a real engine sound is used on the ‘Safe & Sound’ Hybrid technology demonstrator vehicle, making it instantly recognisable that the vehicle is in motion.

Electric and hybrid vehicles, a favourite choice of the environmentally conscientious have recently come in for criticism from blind and partially sighted people. Due to the almost silent operation of hybrid vehicles at slower speed when running on electric power, the independent travel of the blind and partially sighted may be put at risk as they cannot hear these quiet vehicles as they approach, making crossing a road or walking through a car park hazardous.

Mike Kimberley, Chief Executive Officer of Group Lotus plc said “The increased acceptance of greener vehicles such as hybrid and electric vehicles is to be encouraged; they have an important role in improving fuel economy and reducing emissions. Our advanced external sound synthesis technology increases pedestrian safety, while retaining the car’s environmental benefits. We hope that legislators introduce minimum noise requirements for vehicles to encourage the adoption of technologies, such as ours, which will ultimately increase pedestrian safety.”

Clive Wood, Transport Policy Officer at The Guide Dogs for the Blind Association said: “Blind and partially sighted people use the noise of oncoming traffic as a cue for when it is safe to cross a road – if a ‘quiet’ hybrid electric vehicle is approaching then they will no longer have this cue and are immediately put at risk.

Wood continues: “As the leading voice on transport and mobility issues in the visual impairment sector, Guide Dogs believes further research and development is needed to address the issues of identifying 'quiet vehicles' for blind and partially sighted people. The charity recognises the environmental benefits of these vehicles however more consideration needs to be given to the safety implications to visually impaired pedestrians.”

The Lotus ‘Safe & Sound’ Hybrid technology demonstrator uses a standard Toyota Prius, one of the highest volume and most advanced hybrid vehicles to demonstrate the sound synthesis application and compensate for the lack of engine noise emitted by the vehicle when running on an electric motor. What has resulted is the same environmentally conscious hybrid vehicle, without the potential risk to pedestrians and cyclists.

Duncan Vernon, Road Safety Manager, at RoSPA (Royal Society for the Prevention of Accidents) said: “Road safety professionals teach children that they can improve their safety by listening for traffic, and the sound of an approaching vehicle is a warning that most pedestrians will use before making the decision to cross the road. New electric engines make vehicles much quieter, so we need to look at ways of ensuring the safety of pedestrians. We welcome innovative solutions which address this."

The solution that Lotus has devised is a novel reapplication and development of its Sound Synthesis technology. This is a part of the Lotus suite of patented active noise technologies which comprise three main systems, Active Road Noise Cancellation, Engine Order Cancellation and Sound Synthesis.

To synthesise the engine sound, a road speed signal is taken from the vehicle and a waterproof loudspeaker system is positioned adjacent to the radiator allowing the sound to emanate from the front of the vehicle. Once the vehicle has passed, the sound is not heard. When the car is operating on the electric motor only, throttle and speed dependent synthesised sound projects a realistic engine sound in front of the vehicle. The technology was designed around the behaviour of a conventional engine, using an existing engine sound which makes it instantly recognisable with the pitch and frequency helping to identify vehicle distance and speed. If the hybrid’s engine starts operating, at higher speeds or throttle demands or lower battery levels, the control system automatically stops the external synthesis. When the powertrain control system switches the car back to running on the electric motor only, the synthesis controller instantaneously sets the system running again. It is all completely automatic and the driver hears almost none of the additional sound.

In order to generate the engine sound, recordings of a suitable donor engine were made and analysed to establish the characteristic frequencies at different engine speeds. These frequencies are then entered into the synthesis controller in the form of a ‘voice’ which outputs the sound through an amplifier and out through the loudspeakers.

Lotus Eagle to Touch Down at British Motor Show

Eagerly anticipated and making its official global debut at the British Motorshow in London on July 22nd, the first all-new car from Lotus since the iconic Elise in 1995, will enter the sportscar market as the only mid-engined 2+2 in production.

The new car, which is known only by its project name ‘Eagle’, is a more holistic offering than the Elise and Exige models that have been so massively popular with track day enthusiasts. The car, the name for which will be announced at the British Motorshow on 22nd July at an 11:30 press conference, is designed for people who desire exotic sportscar characteristics of stunning design, exclusivity, dramatic proportions and performance. Project Eagle also offers real-world usability and a unique sense of occasion.

Powered by a 3.5-litre V6 producing 280 PS, the new car employs innovative lightweight chassis technology to ensure visceral all-round dynamic performance, in keeping with the great Lotus tradition. Even in the very early stages of development testing, Lotus ride and handling engineers report that it is considerably faster around the famously demanding Nürburgring circuit than the Elise and more stable at speed than the Exige.

Inside, Project Eagle cocoons occupants with a sumptuous leather surfaces juxtaposed with contemporary high-tech features. With driver focused instrumentation the driver sits in cockpit-esque surroundings. A beautifully appointed dash boasts tactile details such as flush-mounted controls that glow with blue LED haloes and a stylised speedometer and rev counter ensuring that controls are both attractive and accessible.

Styled in-house by Lotus Design, the Project Eagle’s sleek, sophisticated and attention-snaring lines brilliantly disguise its ability to accommodate passengers in the rear of the cabin, giving the car the external characteristics of a small, nimble sportscar whilst belying its internal space. As well as being sold in a 2+2 configuration, the car will also be available as a purely twoseater, the space in the rear being allocated to luggage storage. Other derivatives are also planned for the future, including a convertible and an ultrahigh performance version.

Deliveries of Project Eagle will begin in Spring 2009, and with only 2000 of the hand crafted cars planned each year, this exclusive and unique car is creating a real stir with celebrity enthusiasts around the world. Hollywood actor and car enthusiast Patrick Dempsey is just one of the high profile collectors who are on the waiting list for a test drive.

Mike Kimberley, CEO of Group Lotus plc, had this to say about the new model: “Project Eagle is the biggest milestone Lotus has achieved since the Elise was born 13 years ago. We are currently working at broadening the appeal of the Lotus brand through an aggressive 5-year model plan of which this car represents the first exciting step.”

Lotus Elise matches Rivals with Less Power, Weight

Raw power isn’t everything, especially in the world of racing where whoever crosses the finish line first is the winner.

The Lotus Elise, known for emphasizing lesser weight and more handling, is participating in Round 5 of the Shannons Nationals with half the horsepower of more powerful rivals—such as Ferrari, Lamborghini, Porsche and Aston Martin.

The new Elise’s supercharged 4-cylinder engine sports a smidgen more than half the horsepower of an Aston Martin DBRS9 or Lamborghini Gallardo.

While lacking cowbell, it is also a lightweight at 750kg, some 600kg lighter than its rivals. The Lotus is also renowned for having good under brakes and mid-corner speeds.

Driven by Scott Bargwanna, a similar Lotus Elise already placed second in Round Two of the series in Adelaide.

Our take? Whether or not the Lotus Elise can match cars like an Aston Martin remain to be seen. Its rivals have a good long history of tearing up the track and won’t be displaced so easily.

Lotus Eco Elise to debut at British Motor Show

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.

Lotus finds a Partner

Lotus is no stranger to working with other automakers, especially in the form of engineering and handling consultant, it latest partnership however brings forth a level of cooperation unique in its history.

Spyker is not new to using Lotus for its engineering services. Its latest agreement with the brand, though, goes a step further and includes the sharing of ideas, parts, and even platforms. Lotus role in the C8 is set to expand with Spyker's C8 Aileron and they may even play a role in Spyker's D8 off road, Dakar buggy, type vehicle.

There's even a chance that Spyker's and the Lotus Esprit successor may be sharing parts .

Our take? Spykers have been criticized as all looks with no substance, further involvement by Lotus can make them legitimate supercar competitors. Lotus thankfully, should be guaranteed some income.
