They’ve rolled in quietly, without any fanfare, and they’re doing very well indeed. Jaguar’s diesel variants of the XF and XJ have begun selling in Malaysia, and both Diesel S jobs are pretty much being snapped up the moment they arrive.

Both the XF and XJ diesels are similarly equipped with a AJ-V6D Gen III S 3.0 litre turbodiesel mill, offering 271 hp at 4,000 rpm and 600 Nm at 2,000 rpm, mated to a six-speed automatic transmission.

Performance-wise, the lump is listed as giving both models an identical 0-100 kph time of 6.4 seconds and a 250 kph electronically-limited top speed (the cars weigh in at around the same, and in fact the XF is heavier at 1,820 kg to the XJ’s 1,813 kg).

Pricing-wise, the XF Diesel S rolls in at RM499,888, which is just a shade above the 3.0 V6 petrol version’s RM488,888, while the XJ Premium Luxury LWB Diesel S is priced at RM699,888, a very enticing alternative to the 5.0 Premium Luxury V8 petrol variant, considering its asking price is loads lower than the latter’s RM958,888.

Some notes on the XF – the Diesel S isn’t the facelifted version of the car, but the news is that the 2011 model year XF should be arriving on these shores soon. XF fans will of course have to be very patient for the new 187 hp 2.2 litre option of the car to arrive here.
