Jaguar is expanding its product offering with the introduction of two additional petrol units; the new 3.0-litre V6 supercharged petrol, and the 2.0-litre turbocharged petrol.
Adrian Hallmark, Global Brand Director, Jaguar Cars, said: "Jaguar currently has its strongest range of products for several decades. Our continued growth is dependent on two things; activating the awareness of the brand, and expanding our range to enable us to access new customers in both existing and emerging markets. The introduction of these two additional forced-induction petrol engines is integral to this ambitious plan."
The 3.0 V6 S/C petrol engine has been developed by Jaguar powertrain experts from its existing award-winning 5.0-litre V8 — the all-alloy engine which has received plaudits from around the world in applications from long-wheelbase limousines to 300km/h convertibles. The 3.0 V6 S/C shares many of the V8's key technologies, including direct injection, variable valve timing, and aluminium construction and offers comparable levels of refinement and driveability to the naturally-aspirated version of the V8 engine, but with greater specific output and efficiency courtesy of supercharging technology.
In its 250kW/450Nm guise the 3.0 V6 S/C offers the smooth, seamless performance ideally suited to a Jaguar saloon. The 3.0 V6 S/C will give performance levels matching much larger engines while remaining economy and emissions friendly.
The 2.0-litre turbocharged petrol engine uses a range of state-of-the-art technologies for power generation that belies its size, and its introduction to XF models will see it installed in north-south orientation. It produces 177kW and 340Nm thanks to the use of three key innovations: low-inertia turbocharging, direct fuel-injection and variable timing of both the intake and exhaust camshafts.
Ron Lee, Group Chief Engineer Powertrain, Jaguar Cars, said: "Both the 3.0 V6 S/C and 2.0 turbocharged make intelligent use of forced-induction technology to produce high-specific output in an efficient way, while delivering the compelling combination of flexibility, refinement and driver reward that are integral attributes in all Jaguar engines."
Both engines will be mated to the eight-speed automatic transmission that offers a broad spread of ratios for a perfectly balanced combination of smooth-shifting, economy and driver control. The 3.0 V6 S/C and 5.0 V8 S/C come standard with Jaguar's Intelligent Stop-Start system.
In the XF and XJ, the 3.0 V6 S/C will replace the naturally-aspirated version of the 5.0-litre V8 for the 2013 model year. The 3.0 V6 S/C produces 250kW at 6500rpm and 450Nm of torque between 3500 and 5000rpm.
In the XF, this results in 0-100km/h in 5.9 seconds and a top speed limited to 250km/h. Returning a combined fuel economy of 9.4l/100km, the XF emits just 224g/km of CO2.
In its XJ application, the 3.0 V6 S/C accelerates to 100km/h in 5.9 seconds and a limited top speed of 250km/h. The XJ returns a combined fuel economy of 9.4l/100km and emits 224g/km of CO2.
In the XF, the 2.0-litre turbocharged petrol engine is capable of accelerating to 100km/h in 7.9 seconds and on to 241km/h while at the same time achieving 8.9l/100km on the EU combined cycle and CO2 emissions of 207g/km.
