The Lotus Range Extender – designed specifically for the new breed of highly efficient series hybrid vehicles.

lotus-range-extender-engine

Lotus Engineering, the world-renowned automotive consultancy division of Lotus, unveils its Range Extender engine at the 63rd Frankfurt International Motor Show. In a series hybrid vehicle, the Range Extender engine is attached to an electricity generator and provides a highly efficient source of energy to power the electric motor directly or charge the vehicles battery. The battery can also power the electric motor which enables the design of a drivetrain that has low emissions, optimised performance and acceptable range.

The Lotus Range Extender engine features an innovative architecture comprising an aluminium monoblock construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. This results in reduced engine mass, assembly costs, package size and improved emissions and engine durability.

The three-cylinder 1.2 litre Range Extender engine is optimised between two power generation points, giving 15 kW of electrical power at 1,500 rpm and 35 kW at 3,500 rpm via the integrated electrical generator. Its low mass of 56 kg makes it ideal for the series hybrid drivetrain configurations for which it is designed. The engine uses an optimised two-valve port-fuel injection combustion system to reduce cost and mass and, in line with Lotus Engineering’s extensive research into renewable fuels, can be operated on alcohol-based fuels or gasoline.

For successful market uptake of series hybrid vehicles with acceptable driving range, vehicle manufacturers must overcome the challenges of high vehicle cost. The Lotus Range Extender engine not only offers the advantage of a cost effective design, but also its high efficiency and low mass will enable the downsizing of expensive batteries whilst maintaining vehicle efficiency and range. The engine has been designed using production methodologies and the parts procured from low volume potential production suppliers, offering a fast route to market for original equipment manufacturers wanting to source a dedicated range extender for series hybrid vehicles.

Paul Newsome, Managing Director of Lotus Engineering said: “As the world changes, Lotus Engineering continues to change with it, continuously developing solutions for more sustainable transportation. The Lotus Range Extender engine is another example of Lotus Engineering developing new technologies for efficient performance, this time in the area of series hybrid vehicles. The engine concept we have created with its optimised combustion and compact, low mass, low cost construction is a clear demonstration of the expertise and progressive approach Lotus takes for its own research and for its clients.”

The Lotus Range Extender engine has been developed as part of the ‘Limo-Green’ project funded by the UK’s Technology Strategy Board, a collaboration between Lotus Engineering, Jaguar Cars Ltd, MIRA Ltd and Caparo Vehicle Technologies, demonstrating a large, lightweight, prestigious executive saloon with less than 120 g/km CO2 emissions.

Simon Wood, Technical Director of Lotus Engineering said: “Most series hybrid vehicles that are currently being developed will use adaptations of existing, conventional engines which are therefore compromised in the efficiency that they can achieve, designed as they are for a wide range of operating conditions. Designing the Lotus Range Extender purely for use in series hybrids has allowed us instead to develop an optimised engine that has high thermal efficiency, low fuel consumption, multi-fuel capability and a 35 kW peak output from a 1.2 litre, low cost architecture over the precise operating range required by a series hybrid drivetrain.”

Key features of the Range Extender engine in detail:

Monoblock

The Range Extender features a novel engine architecture incorporating a monoblock construction that blends the cylinder head and block together eliminating the need for a cylinder head gasket, improving durability and reducing weight. Approximately 17 parts are eliminated using this approach and the water jacket is better optimised.

Integrated Exhaust Manifold

Lotus Engineering designed and developed a new advanced cylinder head design featuring an integrated exhaust manifold. The production-ready technology can significantly reduce manufacturing costs, emissions and weight. An integrated exhaust manifold has potential to:

o Reduce parts count: 18 fewer components resulting in lower inventory, production, logistics and aftermarket costs

o Weight reduction: total system mass reduction resulting from elimination of separate exhaust manifold

Improved engine durability

Generator

Attached to the engine via the crankshaft, the generator sustains vehicle operation beyond the range provided by the batteries.

Additional Benefits

The Lotus Range Extender engine generates a reduction in emissions through faster light-off of the close-coupled catalytic converter with a reduction in heat loss between the exhaust port and catalyst inlet. Engine operating range is optimised to deliver more efficient running, which also aids underhood thermal management.

Utilisation of the monoblock construction results in an assembly cost reduction, while there is also a reduced catalyst loading requirement because less heat is lost on engine start-up between the exhaust port and catalyst inlet.

Increased vehicle integration flexibility is achieved because of the reduction in mass and the reduced package size leads to reduced space requirements. Particular emphasis has also been placed on the coupling of the generator and NVH signature.

Matthew Melling of Twickenham, UK received the keys of a Storm Titanium Lotus Evora from Luke Bennett, Director of Lotus Cars Limited at the Lotus Headquarters where the new mid-engined 2+2 sportscar is hand built.

Many Lotus dealers around the world have already received their demonstrators and Lotus has, so far, received orders for the next 5 months of production. Demand for Lotus’ award winning Evora has meant that 150 extra new manufacturing staff have been recruited to support assembly operations in Norfolk, UK, a very positive sign at a time when the global motor industry faces huge challenges. Full production is expected to reach the maximum rate by the end of November 2009.

Luke Bennett, Director of Lotus Cars Limited said, “It is quite an emotional time to deliver the first Lotus Evora to Mr. Melling. The whole team has worked incredibly hard to design, engineer and produce such a stunning and high performing sportscar and it is a great feeling to hand over the keys to the first customer today. The Evora has won many awards around the world already so we are not surprised that there is high demand for the car and I am sure that each customer who receives their car will be delighted with their purchase.”

Matthew Melling, a customer of Stratton Motor Company, in Norfolk said, “I was determined to be the first in the world to get my hands on an Evora so with Stratton Motor Company’s help, I laid down my deposit within seconds of the order books being opened last year. I have read all the press reviews of the Evora and am so excited about getting behind the wheel – what a great start to September!”

2010 Lotus Exige Cup 260 specification released

2010 Lotus Exige Cup 260

The track focussed homologated-for-the-road 2010 Model Year Lotus Exige Cup 260 takes design clues and technical innovations from the Lotus Exige GT3 racecar and combines with class leading emissions of just 199 g/km CO2 and exhilarating performance of 0-100 km/h in just 4.1 seconds.

· Extensive use of carbon fibre

· Motorsport lightweight wheels

· Ohlins 2-way adjustable dampers

· Rear chassis stiffness increased by 30%

The Lotus Exige Cup has developed a cult following and a dedicated fan base since the first Lotus Exige Cup 240 was unveiled in 2006. Over the last 4 model years several hundred Exige Cup Cars have been sold, either specifically for race and track use or for a pure road going driving experience. The latest Exige Cup 260, with 260 PS, takes the 38 kg weight savings introduced in the last years model, combines them with the extensive body and aerodynamic improvements and revisions introduced on the 2010 Exige in March 2009 and tops them off with new components and technologies to produce the most focused and pure Exige yet.

Roger Becker, Director of Vehicle Engineering for Lotus said, “The Lotus Exige Cup 260 is the epitome of the Lotus brand philosophy of performance through lightweight. Colin Chapman, founder of Lotus, once said “Adding power makes you faster on the straights; subtracting weight makes you faster everywhere” and the Exige Cup 260 totally proves this, being one of the most exhilarating, focussed and pure sportscars on the road today.”

The 2010 Model Year Exige Cup 260 is fully homologated for road use in Europe and key markets in Asia and North America – a must have for many race competition programmes where a road legal car has to be entered. The Lotus Exige Cup 260 is also eligible to compete in the Lotus Cup Europe race series, organized and run by LoTRDC.

The 2010 Model Year Exige Cup 260 takes the design and aerodynamic changes first introduced on the Exige S earlier this year to enhance the look and improve aerodynamic performance.

The lightweight, unpainted carbon chord composite rear wing is based on the design from the Exige GT3 road car concept shown at the Geneva Motorshow in 2007. Compared to the 2009 Model Year Exige Cup 260 tailgate-mounted wing, it is 181 mm wider and mounted 46 mm higher and 61 mm further back. It is attached to the rear bodyshell clam via rear end plates which not only increases the stiffness of the whole structure but also ensures that as much of the airflow as possible passes over the rear wing. This careful airflow management increases stability, reduces drag and, most importantly, maintains the impressive downforce figures of 42 kg at 160 km/h.

The restyled front end includes a larger, more angular air intake to help funnel more air through the radiator, to improve the efficiency of the engine. Ahead of the front wheels on either side of the main aperture, two larger air intakes increase the airflow to the twin oil coolers. Horizontal vanes, made from lightweight carbon fibre bisect these oil cooler air-intakes to stabilise the airflow to further increase the cooling efficiency.

Mounted below the three air intakes is a new aerodynamic splitter for the 2010 Model Year Exige. Made from lightweight carbon chord composite, the splitter is extended to wrap around the whole of the front end and chiseled side lips are raised to deflect air around the tyres to reduce drag.

Rear chassis stiffness increases by 30%

The Exige Cup 260 now has an evolution of the rear diffuser and structural shear panel based on the version developed for the Exige GT3 race car, which increases the lateral stiffness of the rear subframe by 30% further enhancing its outstanding handling.

The rear diffuser and structural shear panel links the subframe to the main chassis to give greatly increased lateral stiffness to the rear subframe suspension pickup points, resulting in better tyre contact patch control.

This stiffness is also more applicable to those drivers who race or take part in track days using slick tyres that can also be fitted to the Exige Cup 260.

Ohlins two-way adjustable dampers are now fitted as standard, adding even more personalisation of the driving characteristics so the driver can tune the Exige Cup 260 to their driving style and road or track conditions.

A restyled front end and new larger, rear wing that not only reduces drag, but also gives a more muscular stance enhancing the lightweight shrink-wrapped look of the whole car.

Like the 2010 Model Year Lotus Exige S, the 2010 Model Year Exige Cup 260 exploits the Lotus philosophy of using weight reduction to increase performance and reduce emissions. Fuel economy is impressive with an Official European Combined Cycle figure of 8.5 litres / 100 km (reduced from 9.1 litres / 100 km (combined) for the 2009 Model Year Exige Cup 260), a frugal 6.5 litres/100 km on the Official European Extra Urban Cycle and just 199 g/km of CO2 (reduced from 216 g/km of CO2 for the 2009 Model Year Exige Cup 260). Continuous engineering improvements over the last year including careful whole vehicle optimisation has enabled this sportscar to be even better for fuel economy and emissions.

Luke Bennett, Operations Director for Lotus Cars said, “The best thing about the Lotus Exige Cup 260 is its performance, on the track it’s sensationally quick in a straight line and attacks corners with razor-sharp precision. With the lightness and agility you’d expect from a Lotus and the almost telepathic feedback to the driver, this car produces an outrageously fun drive.”

The Exige Cup 260 follows this lightweight philosophy closely. Taking the already lightweight Lotus Exige S, the weight saving programme has looked at all areas of the car where components can be replaced with a lighter version (without pushing the costs beyond the reach of the serious track day driver or clubman racer) or where components can be removed completely without detracting from the purity of the driving experience:

Carbon fibre (resulting in a weight saving of 12kg):-

· Roof Panel

· FIA and HANS compliant driver and passenger seats*

· One piece carbon fibre dash top panel

· Rear tailgate

· Centre tunnel

· Front access panels

· Front splitter (carbon chord)

· Side air intake ducts

· Rear spoiler (carbon chord)

(* The seats are FIA compliant when fitted in conjunction with fixed seat runners that are available as a track only dealer fit option).

Lightweight components (resulting in a further weight saving of 22kg):-

· Lightweight ‘motorsport’ battery

· Ultra-light five spoke forged alloy wheels

· Revised rear engine subframe with lightweight coating

· Lightweight fly wheel

· Lightweight composite bulkhead panel replaces rear window

· Alloy supercharger U-bend pipes

Removing some other non essential components and equipment such as the interior and boot carpets, front mudflaps, battery cover, interior mirror, sunvisors, rear tailgate gas strut, results in a further weight saving of 4kg.

However, as optional extras should a customer wish, air conditioning and an interior noise reduction pack are available, together with the complete range of Lotus metallic, lifestyle and premium paint colours

The MY2010 Exige Cup 260 weighs in at just 890 kg, giving an impressive power to weight ratio of 288 hp / tonne (291 PS / tonne). But, of course, power to weight alone does not make a highly competitive race or track car, so in addition, the Exige Cup 260 has a formidable list of standard performance focused equipment, as follows:-

Lotus Launch Control and Lotus Traction Control – additions recommended for track driving

Lotus Launch Control and Lotus Traction Control was originally developed for the Lotus Exige GT3 racing programme

The launch control allows the driver to determine the number of revs they wish to use during a standing start. Having programmed that limit, the driver then holds their foot down fully on the throttle pedal and sidesteps the clutch pedal for a very quick departure from the line. The clutch damper cushions the severity of the clutch to transmission engagement to minimise the stresses to the drivetrain. The launch control also keeps wheel-spin at bay until 10 km/h (6 mph), after which the traction control assumes its duties.

As with launch control, the amount of traction control required can be dialled in from the driver’s seat and altered on the move to suit the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely inactive. The message display in the new instrument pack displays what degree of traction control is being currently utilised.

Wheels and Tyres

All new Lotus Sport lightweight forged alloy wheels, thought to be the lightest original equipment wheels in the world, weigh just 5.65 kg (front) and 7.75 kg (rear). These ultra lightweight wheels reduce the unsprung mass therefore further improving the handling and contribute a weight saving of approximately 800 g over the already super light forged 2009 Model Year Exige Cup 260 wheels. The wheels are shod with Lotus specific LTS construction and compound Yokohama A048 tyres† to maximise grip and achieve the ride and handling targets set by Lotus engineers.

† For GCC States Yokohama A048 LTS tyres are replaced with Toyo Proxes R888 tyres.

Safety Equipment

Lotus Exige Cup 260 cars have the safety equipment expected of a race car, with FIA and HANS compliant carbon fibre lightweight sports seats*, normal 3-point “Webb Lock” harnesses (four or six point driver and passenger seat belt harnesses are available for track use only).

(* The seats are FIA compliant when fitted in conjunction with fixed seat runners that are available as a track only dealer fit option).

A high tensile steel roll over hoop is now fitted with a body coloured Lotus Sport A-Frame as standard and the chassis is already pre-drilled to fit a full front roll cage – a simple dealer fit process involving just the removal of the roof panel for access prior to fitting. Completing the additional safety equipment is a FIA compliant electronic ignition kill switch, with cockpit and external activation, and a FIA compliant plumbed electrically activated fire extinguisher system, again with cockpit and external switches.

Like all current Lotus cars, the Exige Cup 260 is built around a very strong extruded and bonded aluminium chassis tub. Attached to the chassis is a sacrificial energy absorbing composite front structure designed to help absorb crash energy in the event of impact.


Suspension

To suit individual driving styles and road conditions, drivers will now be able to tune the Exige suspension with the Ohlins two-way adjustable dampers (which have 60 compression and 22 rebound settings) and ride height adjustment to reduce the ride height from 130 mm to 120 mm. An adjustable front anti-roll bar allows customers to tailor the handling characteristics of the car to their own requirements.

As the Exige Cup 260 cars are equipped for track use, a double shear track control arm brace is provided to cope with the expected kerb abuse during track racing or hard track day driving.

Brakes

The brake system includes large diameter 308 mm 2-piece cross-drilled and ventilated front discs and 282 mm cross-drilled and ventilated discs at the rear, upgraded Pagid RS14 sports brake pads set into the brake calipers (AP Racing two piece radially mounted, 4 piston at the front and Brembo sliding at the rear), and stainless steel braided brake hoses – all linked to the proven Lotus track-tuned servo-assisted four-channel ABS system that enhances braking performance and minimizes stopping distance without taking over from the skill of the driver.

Performance, Economy and Emissions

The Exige Cup 260 is one of the quickest road cars around a circuit. Key to this incredible track performance is the aerodynamic package, which produces 42 kg of downforce at 160 km/h (100 mph) increasing grip and stability at higher speeds. With a top speed of circa 245 km/h (152 mph) and a zero to 160 km/h (100 mph) in circa 9.9 seconds, 0 to 100 km/h in circa 4.1 seconds (0 to 60 mph in circa 4 seconds), the MY2010 Exige Cup 260 is the perfect partner for the serious racer. Combined Fuel Consumption is 8.5 l/100km and the CO2 emissions 199 g/km.

Engine

The supercharged and intercooled engine in the Exige Cup 260 has a maximum power output of 260 PS (257 hp) at 8000 rpm and a torque figure of 236 Nm (174 lbft) at 6000 rpm. This significant amount of extra power and torque now available together with the VVTL-i variable cam system ensures that there is a smooth and linear delivery of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The Roots-type Eaton M62 supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) is run from the crankshaft and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through an air-to-air intercooler (the air enters via the enhanced roof scoop) before being fed into the engine itself. All charge air ducting has been kept as short as possible with large diameter pipes to minimise restriction and maximise throttle response and efficiency. Four high capacity injectors and an uprated fuel pump add additional fuel under hard acceleration or continuous high speed driving – only on the track of course!

A lightweight flywheel is fitted (giving even greater flexibility and response to the gear change), a sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to the lightweight C64 six-speed gearbox (with an aluminium casing) – with the same perfectly spaced ratios as the Exige S. A torque-sensing limited slip differential is fitted as standard, with a plate type limited slip differential available as an option. An Accusump (engine oil accumulator unit) is included in the whole package as an oil reservoir back-up for extreme track use ensuring that, under those conditions, the engine oil pressure remains constant.

Electrical supply is provided by a lightweight motorsport battery which saves a massive 5 kg of weight sitting behind the rear axle – again weight saving is not just the removal of mass but ensuring that this mass is removed where it most affects performance and handling.

Roof Scoop

The Lotus Sport Exige Cup 260 has a high flow, full-length carbon roof scoop as part of the lightweight carbon roof panel, which not only saves 4 kg but also ensures efficient cooling through the intercooler, which in turn allows the Exige Cup 260 to gain a higher charge density in the cylinders improving efficiency further.

Tony Shute on the Evora Development cycle

TheManufacuturer.com has a fantastic video of a Tony Shute presentation on the design decisions and the development process that went into the creation of the Lotus Evora. It a bit tech heavy and quite long (38 min) but is definitely worth the watch and I guarantee that it will absolutely delight the engineer inside you.

Some of the highlights:

  1. Went from a clean sheet to final production in 27 months
  2. The front crash structure was designed and tested independent of the rest of the car
  3. The aluminum wishbones on both sides of the front and the rear uppers use the same tooling
  4. Headlight tooling was developed in China but uses UK parts
  5. Radiator acts as a front wing and generates downforces
  6. Main chassis consists of 20 extrusions
  7. Prototypes were built on the manufacturing line

Health benefits of Autocrossing

At the last GGLC autocross Alex and I decided to try out a little experiment to see how your heart rate changes during the race. We used a Polar S720i to record his heart rate, an iPhone for video and a DL1 data logger to record G-force and speed readings. I used some simple PHP magic to sync the two data files together and used the Chasecam Dashware system to create this finished video.

You can see the speed, heart rate (BPM), longitudinal G (acceleration + braking) and lateral G in the dashboard on the top of the video. His average heart rate was in the low nineties while on the grid and rises to to 101 just before the start of the run. As the run progresses you can see it quickly rise all the way to 145 bpm by the end of the 45 second run. Just as interesting is the way his heart rate falls as soon as the run ends and drops to the low 130s just 10 seconds after the run. So now if anyone asks you why you autocross just say its for the health benefits 😉

Unfortunately the video quality is not as perfect and the heart rate only updates every 5 seconds but all in all it was a successful test of the system. I have already ordered a Polar RS800CX (1 sec resolution) and I plan to run this same setup for the duration of the Lemons race at Buttonwillow next month. So stay tuned for the health benefits of endurance racing 😀

Mike Kimberley to step down as Group Lotus CEO

Mike Kimberley
Mike Kimberley

The Chief Executive of Group Lotus, Mike Kimberley, announced today that he is stepping down from his role due to an ongoing back problem. An Executive Committee comprising current Group Lotus board members supported by the shareholder, Proton Holdings Bhd, will assume day-to-day control of the business until a successor is appointed.

Mike, who will be 71 in August, has been suffering from severe back pain for a number of months and underwent surgery in late 2008 which was only partially successful. His doctors have now advised him to retire so as not to jeopardize his long term health. Under these circumstances, the board has regretfully accepted his resignation.

Dato’ Syed Zainal, Managing Director of Proton Holdings Bhd, said: “It is a great shame that Mike’s health has forced his departure earlier than any of us would have liked. He has been a great asset to Lotus over four decades. Since his return in 2006, we have seen a huge turnaround in the fortunes of this great company. He leaves Lotus with our deep gratitude and our very best wishes for his retirement.”

Under Mike’s leadership, Lotus has produced the award-winning Lotus Evora, which was recently launched to the world’s press with universal acclaim. He has also overseen the expansion of Lotus Engineering, one of the world’s most respected high-technology engineering consultancy businesses. Group Lotus now has a positive and stable platform despite the global economic downturn and is delivering against its defined growth targets in the company’s strategic business plan.

Mike Kimberley said: “Sadly, it is on doctor’s orders that I am stepping down but I will leave confident that Lotus is in great shape with a strong management team fully supported by our shareholder in Malaysia. It’ll be very hard to leave knowing that there are such exciting times ahead but I’ll take with me many very happy memories.
