About the 2021 BAC Mono

The latest Mono generation embraces forced induction with a 2.3-liter turbocharged four-cylinder producing 332 horsepower and 295 lb-ft of torque. The switch to an eight-speed dual-clutch transmission marks a significant departure from the sequential manual, offering faster shifts while maintaining the Mono's hardcore character. Despite the added complexity, BAC maintained the car's featherweight philosophy and uncompromising single-seat focus. The turbocharged engine delivers broader torque delivery while the DCT enables more accessible performance for track day enthusiasts. At $190,000, the current Mono offers the most sophisticated iteration of BAC's minimalist philosophy. The improved drivability doesn't diminish the raw experience, this remains one of the most extreme road-legal track cars available. For collectors, this generation represents BAC's maturation while preserving the Mono's essential character, likely becoming the most usable variant for serious track enthusiasts.
