Cons of the Ariel Atom 4R:

  • Limited Practicality: The Atom 4R is a pure sports car designed for performance and driving pleasure. As a result, it offers minimal creature comforts and limited storage space. It may not be suitable for everyday commuting or long trips.
  • Exposed Design: The Atom 4R lacks traditional bodywork and features an open cockpit, which means it offers little protection from the elements. This limits its usability in adverse weather conditions.
  • High Price: The Atom 4R comes at a relatively high price point, starting at £64,950 plus VAT. This makes it an exclusive and expensive choice compared to other sports cars on the market.
  • Lack of Practical Safety Features: Due to its lightweight and minimalist design, the Atom 4R does not come with advanced safety features commonly found in road cars. It is essential to consider this aspect when using the vehicle on public roads.
  • Limited Seating Capacity: The Atom 4R is a two-seater sports car, which means it cannot accommodate more than two occupants. This might not be suitable for those who require additional passenger seating or practicality.
