MG has added a turbo-diesel engine option to its Rover 45-based MG ZS sports saloon range.

MG now offers diesel engines across its full saloon range - from the ZR to the ZT, a move seen as crucial for success in European markets where diesel penetration is rising rapidly (the diesel accounts for 70% of UK Mercedes S-class sales, for example).

The 101Ps ZS turbo-diesel provides high levels of torque - 240Nm@2000rpm - and 0-60mph acceleration in 10.3secs on the way to a 116mph top speed.

Economy is also good - 52.7mpg on the official EC combined cycle.

The turbo-diesel is available in both the 5-door hatchback and 4-door saloon with two trim specifications - ZS and ZS+, the latter with air conditioning, electric front windows and special badges. UK prices start at £13,195 for the hatchback.
