The Barra engines are a family of straight 6s and V8s assembled by Ford Australia since 2002. The name 'Barra' is thought to have been derived from the surname of Rod Barrett, a major 'father' of the Ford i6 redevelopment project. The V8s are built in Windsor, Ontario by the Ford Motor Company and are shipped un-assembled to Australia. Production of the straight 6 is scheduled to continue until at least 2013, when an all new Falcon is rumoured.
The I6s are all DOHC engines with VCT. They are a development of
I6s produced between 1988-2002, which in turn are a development of
the Straight 6, commonly known in
Australia as a "250 Crossflow".
Common specifications to all I6s
Bore: 92.26 mm (3.6 in)
Stroke: 99.31 mm (3.9 in)
Displacement: 3984 cc
Number of valves: 24
This engine was first launched in 2002 with the BA Falcon and was
a development of the previous Intech E-Gas engine. The E-Gas engine
is designed specifically to run on Autogas only. It features a low-performance,
high-reliability, low maintenance Vialle closed-loop single-point
venturi-style LPG-injector-less carburetion system in
lieu of the standard sequential petrol injection system. This
engine was carried over to the current FG Falcon with no revisions since
This engine was produced for the BA Falcon XR6T between 2002 to
2005. It is similar to the Barra 182, except it has a slightly
lower compression ratio, a single Garrett GT35/40r turbocharger,
trademark Bright Red rocker cover and an intercooler.
This was the engine found in the BF Falcon and SY Territory. It
began production since 2005. It is similar to the Barra 182,
however the slight increase in power is also due to an increase in
compression ratio, as well as upgrading the BA's Black Oak ECU to
the more powerful Spanish Oak ECU.
These are found in the BF Falcon XR6T and the Turbo Territory
and have been in production since 2005. It is the same as the Barra
190 except it has a slightly lower compression ratio, a single
Garrett GT35/40r turbocharger and an intercooler.
Production commenced in 2004 and it is found in the BA/BF Falcon
based FPV F6 Typhoon and Tornado
models. The increase in power is achieved through the use of higher
boost pressures from the otherwise under-utilised Garrett GT3540
It has a unique blue coloured rocker-cover.
The Barra 195 is the latest version of the naturally aspirated
straight-six engine and is found in the current Ford FG Falcon
sedan and ute (the BF III wagon and Ford Territory SY and SY2 SUV
still use the old Barra 190). Modifications made to the engine
include a revised plastic inlet manifold on aspirated models and
new cylinder head, which have achieved power and economy
improvements over the Barra 190. Although the engine specifications
state that this unit produces 391 N·m (288 lb·ft) of
torque on 91 RON petrol, when fuelled by 98 RON, it can produce
more than 195kW and 420 N·m (310 lb·ft); more torque
(although substantially less power) than the identically sized V8 in the BMW M3which
produces 309 kW at 8,300 rpm and being 400 N·m at 3,900 rpm). These
figures also exceed those of the Falcon's logical competitors in
Australia, the Toyota Aurion powered by the 2GR-FE V6 (Which
produces approximately 200 kw at 6,200 rpm and 336 N·m of peak
torque at 4,700 rpm using 98 octane petrol) , and the Holden
Commodore, powered by the various versions of the Alloytec V6,
including the SIDI (direct-injection) variants.
The figures for the revised turbo engine for the FG XR6 Turbo
mimics the old FPV turbo I6, however this is an incorrect
assumption and the motors are not the same. Firstly there is a
redesigned low profile intake plenum, as opposed to the circa 1994
Broadband Manifold intake which originated in the EF Falcon. The
engine employs a new turbocharger and intercooler in conjunction
with the Barra 195s updates. The result is that the FG XR6 Turbo is
actually faster than both FPV's BF Typhoon and the FG XR8, despite
having less power than either. The FG XR6 Turbo uses a smaller
turbo than the BA/BF XR6 Turbo so it can spool faster, make more
usable power, and make less noise than the larger turbo.
The high power variant of the FG's turbo I6 is found in the new
FPV F6, the fastest mass
produced car in the Southern Hemisphere. Featuring a
larger turbocharger and intercooler, this is the most powerful
engine (and the first to produce more than 100 hp (75 kW)
per litre) manufactured in Australia. As a result, the F6's rolling
acceleration from 80 km/h (50 mph) to 120 km/h
(75 mph) in 2.8 seconds.
Having faced cancellation and the transition to an overseas designed V6 engine, Ford Australia announced that it will continue production of the 4.0L inline 6 on home soil, after receiving increased funding from the Australian government. Ford is using the extra funding to engineer the engine to stricter upcoming emissions standards.
The Barra V8s are based on the Modular engine, however they are
assembled in Australia. All are of the 5.4 litre (330ci) variant
with SOHC driving 3 valves per cylinder and feature VCT. The Falcon
was the first vehicle in the Ford world to have the VCT Modular
engine. There are higher performance V8s called the Boss 260
& 290, and from November 2007, Boss 302 with DOHC and 4
valves per cylinder. They are named in this way due to the kilowatt
output of the engines.
Common specifications to V8s
Bore: 90.2 mm
Stroke: 105.8 mm
Displacement: 5408 cc
Number of valves: 24 (32 for boss series)
This was an optional engine on the BA Falcon and produced
between 2002 to 2005.
Note: Barra 220 is the BA V8 5.4L upgrade for the Falcon models below and above XR series (XT, Futura, Fairmont, Fairmont Ghia, Fairlane, Fairlane Ghia, LTD).
Is an option on the BF Falcon. The extra power comes from a
slight increase in compression ratio. This is done safely with the
addition of another knock sensor. In production since 2005.
Note: Barra 230 is the BF V8 5.4L upgrade for the Falcon models below the XR series.
This engine was found in the BA and BF XR8. Although it produced
more power and torque than the Barra 240T, the V8's peaky tuning
meant it was actually slower.
Featured in the BA FPV GT, this hand built engine produced more
power than the 260. This engine was later slotted unchanged into
the FG XR8.
The 302 featured in the BF FPV GT.
The Boss 315 is featured FG FPV GT. Despite having
45 kilowatts (60 hp) and 18 N·m (13 lb·ft) more
than the FG XR6 Turbo, the V8 is slower to 100 kilometres per
hour (62 mph); 5.1 seconds against 5.3 seconds (New Zealand
Autocar August 2008)
