MG Rover will finally be releasing XPower variants of their acclaimed ZR,TF,ZS and ZT models. The ZR-X will use a uprated version of the 1.8Turbocharged K-Series engine, increasing power from 160hp to 210hp. This will be complemented by a sports exhaust and close-ratio gearbox. The TF-X will use the same engine and have similar upgrades. The ZS-X and ZT-X will use modified 2.5V6 engines increasing output from 177hp to 250hp. All this sounds fantastic with proper performance models finally appearing after all MG's promises 4years ago.
