Thanks to the extensive weight saving programme 3.0 CSLs tipped the scales at 1165kg, some
210kg less than the standard 3.0 CS / CSi. Quoted performance figures were a top speed of 140mph and 0-62mph time of 6.7 seconds.
The CSL road car’s engine was bored from 89mm to 89.25mm and displacement rose by 18cc to 3003cc. Compression was kept at 9.5:1 as per the standard CSi while the original Zenith carbs were replaced with electronic Bosch fuel-injection. Peak output rose
from 178bhp at 6000rpm to 200bhp at 5500rpm. There was also a useful torque increase with 204lb ft now on top at 4300rpm.
