Introduction
As Jaguar expands its product offerings in key global markets, it
is introducing two additional engines; a new Supercharged 3.0‑liter
V6, and a Turbocharged 2.0‑liter I4, which will be offered as
choices on a number of models.
The first announced utilization of the 380hp Supercharged 3.0L V6
will be the
all‑new Jaguar F‑TYPE two seat roadster, coming in 2013. The
Jaguar F‑TYPE will focus uncompromisingly on delivering a rewarding
drive experience
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 engines is
integral to this ambitious plan."
The new V6 engine has been developed by Jaguar from its existing
5‑liter V8. This all aluminum alloy engine has received accolades
from around the world in applications from luxury sedans to 186MPH
convertibles. The V6 uses many key technologies from the V8 engine
including direct injection, variable valve timing and aluminum
construction. It will offer comparable levels of power and
refinement to the naturally‑aspirated version of the V8 engine, but
with greater specific output and efficiency courtesy of
supercharging.
The Turbocharged 2.0‑liter I4 engine uses a range of technologies
for power generation that belies its size. It produces 240hp 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
these new engines 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 a new eight‑speed automatic gearbox
which offers a broad spread of ratios for an optimally balanced
combination of performance, economy, and driver control. The 3.0 V6
S/C will also be available with Jaguar's Intelligent Stop‑Start
system.

This new engine finds it's bloodline from the current Jaguar V8
engine. The all‑aluminum architecture of the V8 forms the basis of
Jaguar's new supercharged V6. The engine will be presented in two
states of tune depending on its application; the 380hp version and
a 340hp version.
The new quad‑cam V6 shares its all‑aluminum construction with the
V8, with the lightweight die‑cast block supplemented with
cross‑bolted main bearing caps to increase rigidity and therefore
refinement.
The valves themselves are subject to control by a dual independent
variable cam timing (DIVCT) system which is activated by the
positive and negative torques generated by the movement of the
intake and exhaust valves. This variable timing system features
actuation rates of more than 150 degrees per second throughout the
rev range, to optimize power, torque and economy at all engine
speeds.
This responsive and uninterrupted power delivery is made possible
through the use of spray‑guided direct injection (SGDI) which
delivers precisely measured quantities of fuel directly into the
center of the combustion chambers at pressures of up to 300 bar
(2,176 PSI). The fuel is delivered several times during each
combustion cycle, creating a more homogenous air‑fuel mixture for
cleaner and more efficient combustion.
To maximize combustion efficiency, these spark plugs are precisely
oriented both in relation to the injector and within the combustion
chamber. The compression ratio is also raised from 9.5:1 in the
supercharged V8 to 10.5:1 in the supercharged V6, further improving
fuel economy and reducing emissions.
Mounted in the 'V' of the engine is latest‑generation Roots‑type
twin vortex supercharger, which is the key to achieving
high‑specific output and efficiency. A water‑cooled intercooler
reduces the temperature of the intake air to optimize power and
efficiency. The supercharger boost control is electronically
managed by new Bosch engine management software. The engine
features a system of counter‑rotating front and rear balancer
weights which lend it the same smoothness and refinement
characteristics as its larger V8 brother.
The V6 powertrain will be completed by a Jaguar‑tuned ZF
eight‑speed automatic transmission. This transmission's large
spread of ratios allows the engine's prodigious power to be fully
exploited while optimizing economy and emissions.
Efficiency is also boosted by an Intelligent Stop‑Start system
which improves fuel consumption by up to seven per cent in European
Test Cycle.* Utilizing a twin solenoid starter, the system is able
to restart the engine in less time than it takes for the driver's
foot to move from the brake to the accelerator. In engine
stop‑start 'change of mind' scenarios, it is able to reenergize the
engine via rapidly reintroducing fuel into the cylinders.
Details: Turbocharged 2.0‑liter I4
The introduction of the Turbocharged I4 to the Jaguar range brings
greatly improved efficiency* with competitive power outputs. This
new engine will be used in a longitudinal configuration and mated
to the new ZF eight‑speed automatic transmission that will be used
on the V6. Again, this transmission's large spread of ratios
maximizes both performance and efficiency. Producing 240hp at 5,500
rpm, this engine offers a highly flexible powerband.
With a weight of only 304 lbs (138kg), courtesy of compact
dimensions and all‑aluminum construction, it is the lightest engine
ever fitted into a production Jaguar. This low mass improves
dynamic agility while bringing further emissions and economy
benefits.
The engine uses of a low‑inertia turbocharger that enables it to
produce its high‑specific power and torque outputs. The
turbocharger is fed via a lightweight thin‑walled exhaust manifold
which offers a shorter engine warm‑up period and faster catalyst
light‑off. Chain‑driven cams operate with variable timing on both
the intake and exhaust valves to maximize the broad spread of
torque.
The engine features specialized coatings on the piston rings and
tappets in order to reduce unwanted internal friction. Efficiency
and power gains are also realized using direct injection
technology. Fuel is injected in precisely measured doses several
times during each combustion cycle to ensure the most efficient
possible burn with the maximum benefit in terms of power generation
while maintaining the lowest possible fuel consumption and
emissions.
Significant steps have been taken to ensure expected levels of
smoothness and sophistication refinement including twin balancer
shafts, active engine mounts, an acoustic engine cover, and the use
of additional sound insulation.
