The new 2.2-litre turbo-charged diesel is coupled to a six-speed manual gearbox on Jaguar X-Type sedans and estates, giving high torque peaking on overboost at a solid 400 Nm (DIN).
Taking 80-120 km/h acceleration in fourth gear as an example, Jaguar says the X-Type 2.2D is timed at 6.2 seconds, putting it ahead of the pack in its segment and comparable to cars with much larger petrol engines.
In addition the 2.2 X-Type - which meets the new Euro IV emissions legislation standard - has the high level of ride and handling ability usually associated with Jaguar.
The state-of-the-art four-cylinder unit produces 114 kW and 366 Nm of torque, available from as low as 1 800 r/min.
An overtaking 'over-boost' facility bolsters the torque to allow for better response. To cope with these loads Jaguar couples the engine to a new six-speed manual transmission.
"The new 2.2 litre engine gives X-Type Diesel customers more of what we know they like: more power, more refinement and of course more choice," says Jaguar Cars SA managing director Thomas Viehweg.
Jaguar says the 2.2D engine produces quietness figures that are among the best in class coupled with extremely low levels of vibration.
Says Phil Hodgkinson, UK based programmes director, Jaguar Cars: "This sporty yet refined engine delivers genuine power and effortless performance with impressive overtaking ability, while also returning excellent fuel economy for the rational buyer."
The turbo overboost comes in when the driver applies full throttle, giving an 11% increase in torque - ideal for quick, secure overtaking.
This high torque output means the X-Type 2.2D is one of the quickest four-cylinder diesel cars on sale today, with the saloon accelerating from 0-100 km/h in 8.9 seconds and reaching a maximum speed of 220 km/h.
Jaguar claims overall fuel consumption of the order of 6 litres/100 km.
The usual diesel engine noise is concealed by a technically advanced acoustic trim used to line the engine bay, while the car's undertray is also acoustically tuned to absorb certain frequencies created during engine start-up.
The 2.2D's engine mounts have also been engineered to neutralise potential vibration into the chassis while extensive rig testing allowed the team to apply further noise absorption materials to the engine itself.
The new 2.2 litre Diesel X-Typpe positions Jaguar's compact saloon and estate range at the heart of the premium performance diesel marketplace, with the X-Type now available in three engine variants ranging from 2-litre V6 petrol, through the diesel models up to the 3-litre V6 petrol all-wheel drive models.
A Bluetooth wireless system is now also available for any X-Type model.
With Bluetooth, a compatible telephone may be wirelessly operated via the car's controls, without ever leaving the driver's pocket or briefcase, for easy, hands-free use.
The Jaguar X-Type 2.2 Diesel saloon will be available in SA from November 1 at R288 000 (including a 5-year/100 000 km maintenance plan).
The Estate version will be introduced early next year, and the price will be announced then.
