Mini Cooper JCW
Mini Cooper JCW — spec data and generation history.

John Cooper Works — the hot trim of the Mini Cooper, named after the Cooper Car Company that built the Mini Cooper S of 1961. R53 JCW (2002–2006) was a dealer-fit kit on the supercharged R53 Cooper S, then BMW factory-built (208 bhp); R56 JCW (2008–2014) used the 1.6 turbo Prince engine (208 bhp); F56 JCW (2015–2024) moved to BMW's 2.0 turbo (228 bhp, 231 bhp facelift); F66 JCW (2024–Present) is the current 2.0 turbo car (228 bhp). All FWD only. The hottest production Mini you can buy, but BMW M2 territory in price.
