Following the success of his Ultima GTR project, Lee Noble created a Lotus 23 replica in 1996 with a wider track than the original to allow for the use of wider tyres. With a lower level of adherence to the original design than the Xanthos, it proved successful in racing, with over 60 cars produced using either Lotus TwinCam or Renault V6 engines. Noble's version continued in production, first by Auriga Design using an Alfa Romeo engine and transaxle, and now as the C23 Lotus 23 replica by Mamba Motorsport near Oxford, UK using Ford Duratec Engines. LusoMotors LM23 The Portuguese LusoMotors kit-car company with João Matoso dynamics engineering support built a reinterpretation of the Lotus 23 (called LM23) which was shown at NEC 2009. Tiger Racing ERA30 The UK Based Tiger Racing ERA 30 takes its design inspiration from the Lotus 23 although the car has been designed to be slightly larger with wider tyres and bigger brakes.
