ZT135 CDTi Tech'

MG announced on Oct 11, 2002 an enhanced performance diesel powered MG ZT saloon and MG ZT-T estate car. The ZT/ZT-T 135 CDTi offers increased levels of power and torque over the recently launched ZT CDTi, with power rising from 116Ps to 131Ps and torque from 260 to 300Nm.

Appealing to the sports orientated motorist who requires high levels of fuel economy, the MG ZT/ZT-T 135 CDTi diesels have competitive levels of performance. The saloon 135 CDTi is capable of 0-60mph in 10.3 secs (11.0 for the regular CDTi), 30-50mph (4^th gear) in 7.3 seconds and a top speed of 120mph. In terms of economy the ZT 135 CDTi has an official Combined figure of 48.8mpg – the same as the ZT CDTi.

With winter looming, Rover has introduced for ATC equipped diesel-powered 75 Saloon and Tourer models an optional parking heater. Activated by a timer control or instantly by a long-range remote control plip, the parking heater is designed for cold days when de-iced windows and a warmed interior can make for a comfortable and safe start to a journey.

The timer control unit, sited within the centre armrest, can be programmed to warm the car interior with three-programmable switch-on times and a fixed 30-minute heating cycle. Alternatively, the remote control can operate the parking heater to either override the timer or activate additional operation times of up to 60 minutes, from a range of up to 600 metres.

The parking heater system, when activated, enables both the fuel-burning heater and the car’s heating and ventilation system to function independently of the ignition, with heated coolant pumped around the engine and circulated in the cabin.

Tests carried out in Scandinavia, with temperatures below –32^oC, showed the parking heater producing an interior level of 24^oC, allowing the engine to start with ease and the windows cleared with a single wipe. Without it several minutes would pass before reaching 0^oC when it would become safe to drive.

The parking heater option is priced at £400. Below is a differences spec sheet. Dor the base CDTi spec see here.
