Falcon Engine to Power Jaguar...

[csv8]

Turbo 2.0-litre, supercharged V6 join British marque's chase for fuel economy.

Jaguar, the luxury car marque once known almost exclusively for its silky six-cylinder engines and growly V8s, has announced it will add a version of the Ford Falcon four-cylinder petrol engine to its line-up.

The company has also revealed it will fit a supercharger to its 3.0-litre V6 for an upcoming mid-life refresh of both its XF and aluminium-bodied XJ models that will include stop-start technology to switch off the engine while stopped in traffic.

Both the 2.0-litre four-cylinder engine and the V6 will be mated to an eight-speed automatic transmission that will be a standard feature across the Jaguar car range.

Adding the supercharger in between the banks of the V6 appears to have resulted in the demise of the normally aspirated 3.0-litre V6 petrol engine, although buyers can still choose between the existing 2.2-litre turbo diesel four cylinder, or 3.0-litre turbo diesel V6 engines in various states of tune, or the normally aspirated or supercharged 5.0-litre V8.

The 2.0-litre petrol engine fitted to the XF saloon will produce 177kW of power and 340Nm of torque — slightly less than the figures produced by the version of the in-line four used in the Ford Falcon — while officially using only 8.9L/100km on the European cycle, and producing 207g/km CO2. Again, this compares with the Falcon’s 8.1L/100km and 192g/km CO2 for the base-model XT and 8.5L/100km and 201g/km CO2 for the more upmarket G6 models.

Also available in the bigger XJ, the 2.0-litre engine will officially sip 9.3L/100km with emissions capped at 216g/km.

The supercharged V6, however, produces a much healthier 250kW of power and 450Nm of torque from fairly high in the rev range, compared with 175kW/293Nm for the atmo engine it replaces.

As well as the performance gain, the supercharged V6 cuts 1.1L/100km from the fuel use of both the XF and XJ, which falls to 9.4L/100km and 224g/km CO2 for both versions.

The 2.2-litre turbo-diesel four-cylinder will now come in two states of tune, offering either 120kW/400Nm or in its higher state of tune, 147kW/450Nm. In the XF, fuel economy is rated at 5.4L/100km, although if you want to drop to less-showy 17-inch wheels it falls to 5.1L/100km.

"The diesel V6 is still offered with either 177kW of power or 202kW in its higher state of tune. Tweaks to its set-up, though, cut fuel use back from 6.3L/100km to a flat 6.0L/100km in the saloon."

The 5.0-litre V8 also becomes more economical, with the normally aspirated version making fuel use gains of about 8 per cent, while the supercharged version improves by about 6 per cent. Both now officially use only 11.3L/100km, with emissions capped at 268g/km.

The XJ limousine comes in for some extra tweaking, too, with Jaguar announcing it has revised the big car’s suspension tuning to offer ‘‘enhanced ride isolation and occupant comfort on all road surfaces, with no impact on the model’s acclaimed dynamic ability’’.

The luxury brand has also said it will offer ‘‘ultra-premium’’ sound systems in its cars developed by British sound specialist Meridian, with power outputs of up to 825 Watts.
