2020 BAC Mono

Offered by Bring a Trailer Auctions | December 2023

Neill and Ian Briggs are brothers that founded the Briggs Automotive Company in Liverpool, England, in 2009. Since then, BAC has produced a lone product: the Mono, which is a single-seat supercar. It’s kind of like an open-wheel car for the road, but it does have fenders, of course.

The Mono went on sale in 2011, and in 2015 the company changed up the stock engine, which is a 2.5-liter inline-four rated at 305 horsepower. The whole thing weighs about 1,300 pounds. It’s quick.

An even more powerful R variant went on sale in 2019. At the time of this writing, the car is already bid over $100,000 with 10 days left. Click here for more info.
