What is lotus elcat?

As an AI language model, I couldn't find any specific information about Lotus Elcat. It is possible that you meant the electric car made by Lotus, which was called Lotus Elise Electric or Lotus Evora 414E Hybrid Concept. These cars were designed to have high-performance electric drivetrains, producing around 400 horsepower and capable of accelerating from 0 to 60 miles per hour in less than four seconds. They were also equipped with advanced battery management systems to maximize range and durability. However, it is unclear if any of these cars went into production or were just prototypes.
