Duratec 30
The Ford Duratec 30 Engine in a Mercury Sable.
The 3.0 L Duratec 30 or Mazda AJ was introduced in 1996 as a replacement for the 3.8 L (230 cu in) Essex V6 in the up-market versions of the Ford Taurus/Mercury Sable. It has 2,967 cc (181 cu in) of displacement and produces between 200 hp (150 kW) and 240 hp (180 kW). With an aluminum block and cylinder heads, it is the same basic engine used in the Jaguar S-Type, Lincoln LS, Mazda MPV, Mazda 6, Mondeo ST220 and many other Ford vehicles. It is essentially a bored-out (to 89 mm) Duratec 25 and is built in Ford Motor Company's Cleveland Engine #2 plant in Cleveland, Ohio. A slightly modified version for the Ford Five Hundred entered production at the Cleveland #1 plant in 2004.
There are two key versions of the first-generation Duratec 30:
DAMB - The Lincoln LS and Jaguar AJ30 versions have direct-acting mechanical bucket (DAMB) tappets. Output is 232 hp (173 kW) at 6750 rpm with 220 lb·ft (298 N·m) of torque at 4500 rpm.
RFF - The Taurus/Sable/Escape version uses roller finger followers (RFF) instead and produces 201 hp (150 kW) at 5900 rpm with 207 lb·ft (281 N·m) of torque at 4400 rpm.
Variable Cam Timing
The 2006 Ford Fusion, Mercury Milan, and Lincoln Zephyr feature a version of the Duratec 30 using variable valve timing. The engine has an output of 221 hp (165 kW) at 6250 rpm, and 205 lb·ft (278 N·m) of torque at 4800 rpm.
The final major revision of the Duratec 30 was seen on the 2009 Ford Escape and Mercury Mariner small SUVs. Cam-torque-actuated iVCT was introduced in this version along with better breathing heads. The result is a bump from the previous version's 223 bhp (166 kW; 226 PS) to 240 hp (180 kW) at 6550 rpm. The newly refreshed engine made its way into the redesigned Ford Fusion as the optional base V6, and the Mercury Milan as the only V6 for the 2010 model redesign.
Replacement
The 3.0L delivered ample power in the midsize sedan segment, however the Fusion later received the Duratec 35 V6 as a top-tier "Sport" option to remain competitive with larger V6 offerings in the Toyota Camry and Honda Accord. The Duratec 30 remained as a step up from the base I4 in the Fusion, but the Milan kept the 3.0L as its sole V6 until it was discontinued for the 2011 model year. The 3.0L Has the potential to deliver more power, but it is believed to be nearing the end of its development; Ford will begin to phase it out in favor of newer engine lines. The Duratec 30 will be dropped as the higher-end powerplant in the 2013 Escape in favor of the 2.0L EcoBoost I4, which produces similar power, more torque, and better fuel economy. As shown in the 2013 Ford Fusion, the Duratec 30 will also be replaced by the EcoBoost 2.0L. It is unlikely that another revision of the engine will appear in any future Ford vehicles, and will be replaced by the EcoBoost 2.0L I4, and Cyclone 35 V6. The original version of the engine without iVCT is available as a crate engine from Ford Power Products, producing 232 bhp (173 kW; 235 PS).
Other applications
A Twin-turbocharged version of this engine is used in the Noble M400, a British sports car. The engine is rebuilt and tuned to a max power of 425 bhp (317 kW) at 6500 rpm, with a torque figure of 390 lb·ft (529 N·m) at 5000 rpm. Noble has used forged pistons, an oil cooler, a larger baffled oil sump and extra cooling ducts to maintain its durability. 29 L/100 km (8.1 mpg-US)
A racing version of this engine exists and is used on mini prototypes like the Juno SS3 V6. It is a 3.0-liter naturally aspirated non variable timing engines producing between 350 and 400 horsepower with a red line of around 8700 rpm. The engine has a 40 hour racing life span before it needs to be rebuilt with rings and bearings, and has proven very reliable and competitive. The engine has a Jaguar badge, and is branded as a Jaguar 3.0-liter V6 since it is built and mostly sold in the U.K
