Jaguar XE, XF and F-Pace score Ingenium petrols for mid-2017

Jaguar has unveiled model year 2018 updates for its XE, XF and F-Pace model ranges, featuring a pair of tweaked turbo-petrol Ingenium engines for the sedans and an all-new twin-turbo diesel powerplant for the F-Pace and XF – with all of them landing on Australian shores during the middle of this year.

Increased efficiency for the revised petrol engines is thanks to reduced friction, modified direct injection, quicker warm-up times and the introduction of twin-scroll turbocharging.

Identified by the entry-level '20t' nameplate, the 2.0-litre petrol unit – which still produces 147kW of power, but has a 40Nm torque boost to 320Nm – carries over to the XE and is also made available in the XF for the first time.

When paired with the XE, the 20t powerplant completes the zero to 100km/h sprint in 7.1 seconds with combined fuel economy rated at 6.3 litres per 100km and CO2 emissions at 144 grams per km.

The larger XF sedan takes an extra 0.4s to finish the triple figures dash, alongside a 6.8L/100km fuel economy rating and 154g/km of CO2 emissions.

A more powerful 2.0-litre turbo-petrol four-cylinder – denoted by the 25t badge – has been revised for the XE and XF, and makes its debut in the F-Pace SUV developing 184kW (+7kW) and 365Nm (+25Nm).

Zero to 100km/h for 25t model grades stand at 6.3s in the XE, 6.6s in the XF and 6.8s in the F-Pace.

The XE S also receives a power bump of 30kW to a total of 280kW for its 3.0-litre supercharged petrol V6.

Fuel economy and emissions for the 25t variants of the XE and XF are identical to that of their 20t counterparts, while the F-Pace 25t is rated at 7.1L/100km on the combined cycle and 163g/km for CO2 emissions.

Producing 177kW and 500Nm, a 2.0-litre diesel four-cylinder with twin turbochargers and an eight-speed automatic transmission makes its Down Under debut for Jaguar in the XF and F-Pace under the 25d moniker.

This mountain of torque allows the F-Pace to despatch of 0-100km/h in 7.2s on a diesel diet of 5.8L/100km and emissions of 153g/km.

The XF 25d is even more efficient with its 5.3L/100km of fuel usage, 139g/km of emissions and 6.5s triple figures sprint time.

The XE S also receives a power bump of 30kW to a total of 280kW for its 3.0-litre supercharged petrol V6 – which now matches that of Jaguar's F-Type V6 S sportscar – but torque remains unchanged.

MY18 changes also extend to adjustments to specification levels and the introduction of additional safety technologies.

XE and XF variants now offer gesture-controlled boot opening, optional adaptive dynamics that can be added to vehicles fitted with adaptive suspension, and configurable dynamics which allow the driver to adjust their gear shift, throttle and steering preferences.

A 12.3-inch digital instrument cluster is introduced to the mid-size sedan, whilst 20-way adjustable front seats with power headrests and side wing supports are added exclusively to the larger XF sedan.

The XE's suite of safety and driver assistance technologies now includes autonomous emergency braking with pedestrian protection, while blind spot monitoring, forward vehicle guidance and forward traffic alert are new additions which are also added to the XF.

Jaguar says production of their MY18 line-up will start in April.

Light oyster has been introduced as a new interior colour option for the F-Pace line-up, while the Prestige and Portfolio model grades now receive a standard sports steering wheel, as well as forward traffic detection and forward vehicle guidance.

Portfolio-specified F-Paces also see improved front seats with powered headrest height adjustment and manually adjustable winged headrests.

Jaguar says production of their MY18 line-up will start in April, with pricing to be revealed closer to the local release that is currently slated for either June or July this year.
