The new XF will be available with a choice of four engines - 2.7-litre
V6 turbodiesel, 3.0-litre V6 petrol, 4.2-litre naturally aspirated V8
petrol, and 4.2-litre supercharged V8 petrol (depending on market).
All will have that classic blend of power and refinement that makes
Jaguar stand out from its rivals, says Mick Mohan, XF Chief Programme
Engineer: “The XF’s engines combine effortless performance, unrivalled
character and an impeccable pedigree. The six-speed automatic transmission
is the best Jaguar has ever had. The Jaguar Sequential Shift TM manual
gearchange adds a whole new level of functionality. This combination
– already proven in the XK – produces excellent powertrains for a very
Both petrol and diesel V6 engines are offered in Luxury and Premium
Luxury models; the naturally aspirated V8 will be Premium Luxury only
(and Luxury for US models) and the supercharged SV8 has its own unique
specification, for a very logical, easily understood range with only
six major variants.
The Euro IV compliant twin-turbocharged 2.7-litre 24-valve V6 diesel
delivers high efficiency, high performance and class-leading refinement
– its headline figures including 207PS (EEC) and 435Nm (EEC) of torque.
With its Compacted Graphite Iron (CGI) cylinder block and aluminium
cylinder heads it is the lightest diesel engine of its type and size
- making a significant contribution to the new XF’s power-to-weight
ratio, performance and fuel economy.
The V6 diesel features the latest generation high-pressure Common Rail
direct-injection, ‘multiple pilot’ injection, and piezo-electric injection
control, allowing sophisticated management of the injection patterns
to make combustion smoother and quieter. Four valves per cylinder and
advanced combustion chamber shapes contribute to high combustion efficiency
with low combustion noise, alongside very low mechanical noise levels.
Emissions are further reduced by using twin variable-geometry turbochargers
with electronic control, exhaust gas recirculation, and a variable-swirl
intake system. Using two small turbochargers, with ‘drive-by-wire’ throttle
control, rather than one larger unit, also gives a quicker, smoother
The 3.0-litre V6 petrol engine is another compact, lightweight, all-aluminium
design with four overhead camshafts, four valves per cylinder, VCP Continuously
Variable Cam Phasing and variable geometry air intakes. It produces
240bhp (SAE)/238PS (EEC) and 221lb ft (SAE)/293Nm (EEC) peak torque
- with more than 80 percent of peak torque from below 1500rpm to maximum
engine speed at 6800rpm.
Variable Camshaft Phasing produces faster response and performance
at all engine speeds - with more torque at low speeds and maximum power
at high speeds. It also provides internal exhaust gas recirculation,
reducing both hydrocarbon and NOx emissions.
The 4.2-litre V8 comes in naturally aspirated or supercharged versions.
With a ribbed aluminium block and cylinder heads it is very light but
extremely strong, and its superb structural stiffness minimises radiated
engine noise and increases mechanical reliability. The V8’s exhaust
system has also been completely retuned to remain quiet at cruising
speeds but deliver a substantially more purposeful V8 roar under hard
In naturally aspirated form it develops 300bhp (SAE)/298PS (EEC), and
310lb ft (SAE)/411Nm (EEC) of torque. The supercharged version uses
a highly efficient rotor-type supercharger, belt-driven from the crankshaft.
It develops 420bhp (SAE)/416PS (EEC), and 408lb ft (SAE)/560Nm (EEC)
of torque from low engine speeds. Just as important as the supercharged
engine’s peak torque is the way the usable torque is spread across a
wide rev range - with at least 86 percent of the peak from 2000rpm to
maximum engine speed.
A superior six-speed automatic transmission – renowned as one of the
best in the world and already proven in other Jaguars - is used on all
versions of the new XF. There is no manual gearbox option. The transmission
is a key element in the XF's sporting character, its adaptive gear-changing
strategies responding both to road conditions and the way the car is
being driven, giving the smoothest shifts and optimum performance. Adding
another layer of driver focus, the transmission is controlled by the
new JaguarDrive Selector TM with the option of manual selection through
Jaguar Sequential Shift TM. The JaguarDrive Selector TM is also used
to access the XF’s Sport mode which uses shift-by-wire technology pioneered
on the XK.
These high-tech, modern powertrains give every XF model outstanding
performance. The 2.7-litre V6 diesel reaches 60mph in just 7.7 seconds
(0-100kph in 8.2 seconds) and has a top speed of 143mph (229kph). The
3.0-litre V6 petrol version sprints to 60mph in 7.9 seconds (0-100kph
in 8.3 seconds) and goes on to reach 148mph (237kph). The naturally-aspirated
V8 model has a superb 0-60mph time of just 6.2 seconds (0-100kph in
6.5 seconds) and has an electronically limited top speed of 155mph (250kph).
Lastly, the supercharged SV8 XF storms to 60mph in just 5.1 seconds
(0-100kph in 5.4 seconds) and, like the naturally aspirated V8, is limited
to a maximum of 155mph (250kph).
