What owners say

Chiron

Overall

Extremely positive sentiment overall, with the vehicle universally praised as a monumental engineering achievement. It is described as the perfect evolution of its predecessor, offering a 300+ mph (483+ km/h) top speed capability, immense high-speed stability, and significant dynamic improvements over earlier models. The Chiron is celebrated for being both an incredibly fast hypercar and a comfortable, luxurious grand tourer, capable of being driven by anyone.

Best version to buy

Chiron Super Sport 300+ is specifically highlighted for its top speed credentials and performance figures. The Chiron Sport and Chiron Pur Sport are also mentioned in comparative lists, but insufficient data exists to declare a consensus "best" version.

Known issues

  • Extremely high maintenance and service costs: cited as approximately €50,000 ($54,000 USD) per year for basic upkeep, with service charges described as 5x higher than some competitors. Frequency: recurrent.
  • Tire durability concerns: tires reportedly cracking after approximately 4,000 km (2,485 miles) and wearing out in as little as 20 miles (32 km) when driven at top speed. Frequency: recurrent.
  • Radiator design flaw: mentioned as a cause of constant radiator issues related to the W16 engine layout. Frequency: isolated.

  • Hybrid system electrical/software failures: Very frequent issues including cars going into protective limp mode, failure to charge properly (charger disconnects spontaneously), high-pitched whining noises from the system, and general tempe…
  • General reliability and breakdowns: Cars described as "unreliable," "problematic," and prone to breaking down constantly, especially during rallies or hard use.
  • Complexity and maintenance demands: The vehicle's extreme complexity (nearly 100 small computers, ~30 main control units) makes it finicky and sensitive to improper treatment.
