Ford Barra engine

The Barra engines are a family of straight 6s and V8s assembled by Ford Australia since 2002. 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. However, in 2011 the engines were replaced with the "Coyote" direct injection V8 from the United States.

Petrol

Barra 182

This was the engine in the BA Falcon, Futura, Fairmont, Fairmont Ghia, XR6 N/A, Fairlane, Fairlane Ghia, RTV, SR, ES, XL, XLS utes and the SX Territory and were produced between late 2002 to mid 2005.

Power: 182 kW (244 hp) @ 5000 rpm

Torque: 380 N·m (280 lb·ft) @ 3250 rpm

Barra 190

This was the engine found in the BF Falcon and SY Territory. 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 (255 hp) @ 5250 rpm

Torque: 383 N·m (282 lb·ft) @ 2500 rpm

Barra 195

The Barra 195 is the latest version of the naturally aspirated straight-six engine and is in the 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 over 200 kW (272 PS; 268 hp) and 420 N·m (310 lb·ft); more torque (although substantially less power) than the identically sized V8 in the BMW M3, which produces 420 PS (309 kW; 414 hp) 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 (272 PS; 268 hp) 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 (261 hp) @ 6000 rpm

Torque: 391 N·m (288 lb·ft) @ 3250 rpm

Turbocharged petrol

Barra 240T

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.

Power: 240 kW (322 hp) @ 5250 rpm

Torque: 450 N·m (332 lb·ft) @ 2000-4500 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 (329 hp) @ 5250 rpm

Torque: 480 N·m (354 lb·ft) @ 2000-4500 rpm

Barra 270T

Barra 270T Display

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 turbocharger.
It has a unique blue coloured rocker-cover.

Power: 270 kW (362 hp) @ 5250 rpm

Torque: 550 N·m (406 lb·ft) @ 2000-4000 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 (362 hp) @ 5250 rpm

Torque: 533 N·m (393 lb·ft) @ 2000-4750 rpm

Barra 310T FG

The high power variant of the FG's turbo I6 is in the new FPV F6. 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) is 2.8 seconds.

Power: 310 kW (416 hp) @ 5250 rpm

Torque: 565 N·m (417 lb·ft) @ 1950-5200 rpm

Liquefied petroleum gas

Barra E-Gas

This engine was launched in 2002 with the BA Falcon and was a development of the Intech E-Gas engine. The E-Gas engine is designed 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 but replaced in mid-2011 by the EcoLPi system.

Power: 156 kW (209 hp) @ 4750-5000 rpm

Torque: 374 N·m (276 lb·ft) @ 2750-3000 rpm

Barra EcoLPi

This engine was launched in 2011 as a replacement for the E-Gas engine. It features a liquid phase injection autogas system which exceeds the power and torque outputs of the contemporary petrol engine.

Power: 198 kW (266 hp) @ 5000 rpm

Torque: 409 N·m (302 lb·ft) @ 3250 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. 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 (295 hp) @ 4750 rpm

Torque: 472 N·m (348 lb·ft) 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 (308 hp) @ 5350 rpm

Torque: 500 N·m (369 lb·ft) @ 3500 rpm

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