Automobili Lamborghini has selected Zircotec to supply a high-performance thermal barrier for the lightweight Murciélago LP 670-4 SuperVeloce. The ceramic-based thermal coating is applied to the exhaust system and reduces the need for heat shields while allowing heat-sensitive, lightweight materials to be used in close proximity to the exhaust pipe. Zircotec’s Thermohold technology also protects other heat-sensitive components from damage.
“Lamborghini previously used Zircotec for its Reventón, where a durable solution to protect the composite bodywork and components around the exhaust was required,” said Peter Whyman, Zircotec’s sales and marketing director. “This time, the coating helped contribute to an overall weight savings of 100 kg over the normal Murciélago, with 33 kg of the reduction coming from the new powertrain and exhaust system.”
“Zircotec helped us in achieving the attention to detail in weight reduction on this program,” said Luca Meschiari, head of exhausts at Lamborghini. “Their coating helps save weight, yet is also durable and meets our requirements in terms of performance and quality more than other solutions we have seen.”
The coating is plasma-sprayed, in effect welding it to the base material and making it more resilient during heat cycling, abrasion and life testing. The whole process eradicates the need for heatshields and wraps that add weight and complexity.
