The 3.0-litre V6 and a 2.0-litre turbocharged four-cylinder will both arrive in Australia around November, coinciding with 2013 model year updates to the XF and XJ model lines. The four-cylinder engine will become the new entry-level luxury offering in Jaguar's local line-up, and has its sights firmly set on stealing sales from the Audi A6, BMW 5-Series and Mercedes-Benz E-Class.

The all-aluminium supercharged 3.0-litre V6 draws on key technology from the larger supercharged 5.0-litre V8 that is found at the business end of the brand's three current model lines.

The lightweight direct-injection quad-cam V6 will be available in two states of tune: one with 254kW/450Nm and another with 283kW/460Nm. The former propels the XF and XJ from 0-100km/h in 5.7 seconds, and while performance figures for the latter are yet to be revealed, it is expected to outperform the existing naturally aspirated V8.

Jaguar insists all other figures – including torque, acceleration times and fuel consumption – have not been finalised, although it says the V6 will offer greater specific output and higher efficiency than the V8 thanks to its supercharger and stop-start engine technology.

The second new powerplant is a turbocharged 2.0-litre in-line four-cylinder. The engine is one of Ford's 'EcoBoost' units and will be similar to the one used to power the four-cylinder Ford Falcon. Jaguar's version produces 177kW/340Nm, matching the output of its Jaguar Land Rover cousin, the Range Rover Evoque, and helps the XF to triple figures in 7.5 seconds.

The 138kg all-aluminium engine will become the lightest ever fitted to a Jaguar production car.

Both engines will be teamed to an eight-speed automatic transmission produced by ZF and tuned by Jaguar.

The turbocharged in-line-four and supercharged V6 will join Jaguar's existing powerplant range that includes 2.2-litre four-cylinder and 3.0-litre twin-turbo V6 diesels, as well as the naturally aspirated and supercharged V8s.

Jaguar Australia brand manager Kevin Goult told CarAdvice the four-cylinder engine would be offered only in the XF, while the lower tune of the V6 will be used in both the XF and XJ.

Goult said the 2.0-litre XF would be "very competitively priced" against the German trio - specifically the $77,900 Audi A6 2.0 TFSI, $77,900 BMW 520i and the $95,300 Mercedes-Benz E250 - adding that it would be a "very strong contender" at the lower end of the luxury-car segment.

The F-Type, due in Australia in mid to late 2013, will get the highest tune of the supercharged V6.
