. It began production since 2005. It is aesthetically the same and mechanically very similar to the Barra 182, however the slight increase in power is also due to an increase in compression ratio due to the slight revision of the cam profile, as well as upgrading the BA's Black Oak ECU to the more powerful Spanish Oak ECU.
Power: 190 kW @ 5250 rpm
Torque: 383 newton metre @ 2500 rpm

Barra 245T

These are 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.
Power: 245 kW @ 5250 rpm
Torque: 480 newton metre @ 2000-4500 rpm

 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 newton metre of torque on 91 RON petrol, when fuelled by 98 RON, it can produce over 200 kW and 420 newton metre; more torque (although substantially less power) than the identically sized V8 in the BMW M3, which produces 420 PS 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, outpowering the Toyota Aurion 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 exceeding the Holden Commodore, powered by the various versions of the Alloytec V6, including the SIDI (direct-injection) variants.
Power: 195 kW @ 6000 rpm
Torque: 391 newton metre @ 3250 rpm

Barra 270T FG

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. 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. This engine also features a 53Nm overboost feature. The feature can engage depending on the driving style and when the accelerator pedal is fully pressed on to the floor can call the computer to overboost and add an additional 53Nm on top of the 533Nm making it a total of 586Nm of torque.
Power: 270 kW @ 5250 rpm
Torque: 533 newton metre @ 2000-4750 rpm

The high power variant of the FG's turbo I6 is 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 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) is 2.8 seconds.
Power: 310 kW @ 5250 rpm
Torque: 565 newton metre @ 1950-5200 rpm

Future

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 Euro IV standards. These will be met partially by fitting the engine with a dedicated liquid LPG injection system, which is slated to emit up to 12% less CO2.

V8

The Barra V8s are based on the Modular engine

The Ford Modular engine is Ford Motor Company's overhead camshaft V8 and V10 engine family, which has been produced in 4.6L, 5.0L , 5.4L, and 6.8L variations. Contrary to popular belief, the Modular engine did not get its name from its design or sharing of certain parts among the engine family...

. 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)

Barra 220

This was an optional engine on the BA Falcon and produced between 2002 to 2005.
Power: 220 kW @ 4750 rpm
Torque: 472 newton metre from 3250-4000 rpm



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).

Barra 230

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.
Power: 230 kW @ 5350 rpm
Torque: 500 newton metre @ 3500 rpm



Note: Barra 230 is the BF V8 5.4L upgrade for the Falcon models below the XR series.
