MG Rover has launched new more powerful turbodiesel versions of the Rover 75 and MG ZT saloons and Tourer (estate car) models. The 135 CDTi-badged newcomers have more power and torque than the standard CDTi versions. Power is up from 116 to 131Ps and torque from 260 to 300Nm. The saloon 135 CDTi reaches 60mph from rest in 10.3 secs (compared with 11.0 secs for the CDTi) but there is no apparent fuel economy penalty - the EU combined cycle figure of 48.8mpg is the same as the CDTi.
