To celebrate the Lexus LFA-hat trick of class wins in the race for the 24 Hours of Nürburgring, Lexus has created the Nürburgring package, a series of aerodynamic properties, suspension tuning and revision of the V10 engine of 4.8 L to give the supercar a profile focused on the track. Shown publicly for the first time at the Geneva Motor Show 2011, the performance option is available only in 50 of the 500 cars to be built. These versions will be produced in 2012, the second full year of production of Lexus LFA.
To improve the performance of the car is driving the neighborhood by adding more downforce at high speeds, Nurburgring Edition is making changes and additions to a number of key carbon fiber reinforced plastic (CFRP) components. These are large front spoiler, half-fin-spoiler, rear fixed wing and fin Canard.
To ensure the Lexus LFA maintains its acceleration time of 3.7 seconds from zero to 62 mph, despite the resistance increases, the V10 engine has been revised to increase peak power by 10bhp to 562bhp. time step in the six-speed sequential transmission is only 0.15 seconds.
What process changes, the package of regulation functions of the suspension and 10mm reduction in ride height. Exclusive mesh-style wheels are introduced, with a dedicated high-grip tires.
exterior color choices are limited to matte black, black, white or orange, the interior finished in black and red, black and purple and black. Cars in Europe, will feature a carbon fiber center console, door panels and seats and carbon fiber race finished in Alcantara.
Customers who inform the package is also offered one-on-one instruction driving on the Nürburgring and chief instructor of the car will enjoy the famous Nordschleife circuit.
carbon fiber parts manufacturing
Lexus LFA production began in December 2010 with a single hand-car was completed in one day. Team of 175 people are involved in the production of CFRP parts, vehicle assembly and painting.
CFRP is exceptionally strong, rigid and light, and represents about 65 percent of the Lexus LFA weight of the body structure. This represents a saving of about 100 kg, compared to an equivalent body in aluminum.
Lexus is for the production and assembly of CFRP components, so that the future development of technology. This is a time consuming process, compared with steel or aluminum, but the LFA, the project provides a valuable test bed for new automated processes used to manufacture the future of Toyota and Lexus models.
different production technologies used in accordance with form, the role and characteristics required for each component.
* Pre-wet: it is an industry standard sheet material of carbon fiber pre-impregnated with epoxy resin. It is used for the Lexus LFA main structural elements, such as the dashboard, and side rails and panels.
* Resin transfer molding (RTM): This is the manufacture of dry plates with epoxy resin injected into the mold. It is mainly used in the Lexus LFA key executives, such as crash boxes, roof rails and the floor of the vehicle.
* Carbon Fiber - Sheet Moulding Compound (SMC-C): This has been used in the manufacture of upper body components and frames, which have intricate designs.
Collage
Lexus LFA group moves through five consecutive processes, each of them has been validated numerically. During the first four - subset, underbody, aluminum parts and body - the junction is used. Final assembly of aluminum parts is fixed mechanically.
This is the first time, Lexus has used collage to assemble the main body, a process that required new measures to control the quality to be implemented to ensure that each of the five stages of the association meets necessary criteria.
