Bay Bridge Bimmers and Minis of Oakland, California has built a twin-engined MINI Cooper that will be coming at this year’s 25 Hours of Thunderhill endurance race.

The custom MINI Cooper recently underwent testing at Sonoma Raceway and is powered by a pair of John Cooper Works 1.6-liter supercharged R53 MINI engines. That means this is an all-wheel-drive race car with around 400 horsepower that has received the nickname of TWINI. Drivers Jacques Andres and Steve Romack will pilot the MINI at this year’s Thunderhill event and Andres recently piloted it during the test sessions.

According to Andres, the initial three laps in the Cooper “exceeded his expectations in handling and performance.” The team will continue fine tuning the car’s suspension and aerodynamics, as well as making sure that it will last the full 25 hours of endurance racing.

    History repeats, i remember the original twini, i believe it had a total of over 200hp, had a remarkable crash where one of the engines locked up - ouch !! driver survived and recovered fine. early 60's i believe. And lets not forget the twin hyabusa powered z cars minis with over 300hp - but a far superior power to weight.
