Lotus Sport Exige La división de deporte de Lotus ha desarrollado este espectacular Lotus Exige de carreras, el coche fue desarrolla por RTN, equipo responsable del desarrollo del Bentley ganador de las 24 Horas de Le Mans 2003, usando las ultimas técnicas de la competición, crearon una carrocería de fibra de carbono muy resistente y liviano, y lo colocaron en el chasis de aluminio del Exige preparado por el departamento de competición de lotus. Trae un nuevo diseño de suspensión de doble triangulo totalmente ajustable, un motor GM V6 de 3000 CC y 400 CV, caja de cambio secuencial Hewland de 6 velocidades y frenos AP Racing. El Lotus Sport Exige ha sido desarrollado para carreras de Sport Car en Asia, pero se ha construido para poder cumplir la homologación para carreras de GT en el resto de los países. Pues este espectacular coche pasa tan solo 850 Kg. Y el proyecto q fue conducido completamente en secreto ha tomado menos de 6 meses para el desarrollo del Sport Exige. Chris Arnold, gerente general de Lotus Sport explica q el lotus de competición fue desarrollado a partir del chasis del Exige, lo cual han modificado levemente para crear un auto de carreras con un potencial impresionante, pues tan solo hace falta algunas modificaciones en la carrocería y en la suspensión para tener un potencial GT de carreras. Más datos técnicos del Lotus Sport Exige: The Body Lightweight “Z-Preg.” carbon fibre bodywork was specially manufactured for Lotus by RTN, the team responsible for the Le Mans winning Bentley. These panels (front clam, “A” panel, body side and sill, roof, engine cover and rear clam) have been made using an innovative low temperature curing process. The moulds were taken directly from the Sport Exige styling “clay” and the resulting carbon fibre panels are race-ready without having to rely on the costly tooling process used in current carbon fibre technology. This is thought to be the first time that this technology has been used on such large carbon fibre panels. An aerodynamically developed front splitter, carbon fibre rear diffuser and an adjustable carbon rear wing provide increased levels of downforce. The interior of the Lotus Sport Exige is similar to the standard Exige, but the standard roadcar wiring harness is replaced with a full Raychem 25 system incorporating Mil-spec connectors from Beru Formula 1 Harnesses. Conventional fuses are replaced with circuit breakers, and a Stack display with integrated data recording is fitted as standard. A racing bucket seat (driver side only) is mounted as right hand drive to optimise weight balance through right hand corners (most circuits run clockwise). A six-point seat belt, prepared for using HANS Safety System, and a removable steering wheel (with quick-connect coupling) is included in the interior package. The composite energy absorbing crash structure used on the standard road cars is also carried over to the Lotus Sport Exige. This glass fibre composite structure, around five times more energy absorbing than the equivalent steel component, also houses the larger water radiator and provides efficient cooling and air ducting over the carbon front clamshell. A 100 litre FT3 safety fuel cell (with quick refuelling system) is mounted behind the driver and in front of the engine (as with the road-going Exige). A fully plumbed in electrical fire extinguishing system completes the body package. Brakes AP Racing provides the non-ABS braking system, which includes the pedal box (with brake balance bar and cylinders). AP Racing also provides the powerful six piston brake calipers at the front and four piston brake calipers at the rear. These calipers are mated to vented discs (344 mm diameter at the front and 330 mm diameter at the rear). Rims and Tyres Ultra lightweight OZ Racing Chrono single-piece cast magnesium rims (8.8J x 17 ET40 at the front and 11.25J x 18 ET50 at the rear) are shod with Yokohama tyres (250/610-17 at the front and 280/650-18 at the rear). Powertrain: Engine and Transmission A narrow angle V6, 2,998 cc Swindon Racing Engines tuned GM racing engine is mounted longitudinally in the Lotus Sport Exige. The naturally aspirated 32-valve engine produces 400 hp (296 kW or 405 PS) at 7,750 rpm and 294 lb.ft (398 Nm or 40.6 kgm) of torque at 6,500 rpm and has a maximum engine speed of 8,250 rpm. When the light weight of the Lotus Sport Exige is taken into consideration, the power to weight ratio is a phenomenal 470 hp / tonne (0.351 kW/kg or 476 PS/tonne). The engine itself weighs 157 kg. Breathing is via an F1-style airbox and air snorkel from the roof panel of the Sport Exige directly into the six carbon fibre air trumpets. The dry-sump engine, with a bore of 89.0 mm and stroke of 93.7 mm is water cooled and also uses an oil-water heat exchanger to efficiently cool the oil. The whole engine is controlled by a Motec M600 electronic engine management system fitted inside the cockpit. The power is transferred from the engine to the rear wheels via a single mass stepped flywheel, AP Racing twin-disc cerametallic race clutch and Hewland NLT sequential six-speed dog type transmission (with in-line shift mechanism). The gearbox itself is cooled through an oil-water heat exchanger. A limited slip differential (separate power and brake ramp angles) completes the powertrain package. Design The one-off racecar has been designed by Barney Hatt (Principal Designer for Lotus Design), under the direction of Russell Carr (Chief of Design). Taking the already aerodynamic road going Exige, Hatt designed the Lotus Sport Exige with the requirements to carry the design of the Exige and the brand attributes of Lotus into a competitive racecar. Russell Carr explains the work needed to design the Lotus Sport Exige: “The objective was to create a dramatic design and to take into account aerodynamic criteria to produce a race car that was not only competitive but also stunningly good looking. General motorsport regulations also had to be adhered to so the fact that the resulting racecar looks like a natural competition evolution of the road going Exige is a testament to the purity and effectiveness of the original design.” Dimensions The Lotus Sport Exige is slightly longer (350 mm) and wider (100 mm) than the road-going Exige to accommodate the larger engine, wider track, longer wheelbase and to optimise the aerodynamics. The length is mainly from the cockpit rearwards but the short rear overhang design of the road-going Exige is maintained.

  __________________________________________________ ______________ No podemos negar q estamos viviendo la era dorada del automovilismo deportivo, siempre pensé q la mejor era de los Gran Turismo de competición y homologados para le calle fue la categoría GT1 de mediados de los 90, inicialmente súper coches de calle q luego fueron preparados para la competición, por ejemplo: McLaren F1, Ferrari F40, Venturi LM600, Jaguar XJ220, Bugatii EB110S, Etc... Luego llegaron las maquinas q nos volvieron locos a todos, coches de competición homologados para la calle, el primero en llagar el Porsche 911 GT1, un año después aparecería AMG-Mercedes CLK GTR, Panoz GTR-1, Nissan R390 GT1, Lotus Elise GT1 y finalmente el monstruo no menos espectacular Toyota GT ONE!!! Pues aquellos años GT fueron para mí como lo fueron los extinto Grupo B de rallys, coches con un potencial de prototipos con gemelos para la calle. Pues el renacimiento del departamento de Lotus en las carrera GT es de las mejores noticias q he podido escuchar en mucho tiempo, y no se puede negar q el Lotus Sport Exige es una pieza de ingeniería hermosa y con un potencial grandísimo como siempre a sido Lotus. Pues pongo una comparación en fotos del Lotus Elise GT1 1997 y Lotus Sport Exige 2006. Lotus Elise GT1 1997  Lotus Sport Exige 2006  Lotus Elise GT1 1997  Lotus Sport Exige 2006
