M4 CSL Doesn’t Have The Best Power To Weight Ratio Among BMWs

With good reason, BMW has made a big deal about how the engineers were able to shave off 100 kilograms (220 pounds) from the rear-wheel-drive M4 Competition to create the CSL. The track-focused coupe weighs 1,625 kg following the Draconian diet, while the inline-six engine has been massaged to produce an extra 40 hp for a grand total of 550 hp.
