JAGUAR revamped its mid-size XF range just one year after launching the all-new model in Australia, but not because there was anything all that wrong with the car. It’s just a matter of timing with producing a new generation of diesel (3.0-litre V6) and petrol (5.0-litre V8) engines. There are no other major changes to the car, but both new engines are a huge step ahead of the previous units, providing much better performance while delivering slightly better fuel consumption and emissions levels. But the new engines also bring a big increase in price.
