New Ford 3.5 V6

Ford announced this week that its new crossover utes â€“ the Ford Edge and Lincoln Aviator â€“ will be the first vehicles equipped with its all-new 3.5-liter V6. The new engine will eventually power one in every five Ford vehicles on the road by the end of the decade, the automaker says.

Aviator will premiere at the North American International Auto Show in Detroit in January and go on sale late next year. Thers is no official word yet from Ford on the timing of the Edge debut and launch.

The new engine, rated produce 250 horsepower and 240 lb-ft of torque in the Edge and Aviator, was designed to deliver improved fuel economy, refinement and performance, while being compact enough to fit into a variety of vehicles. The height and width of the engine is the same as the smaller displacement Duratec 30 V6.

The engine uses a dual-overhead cam valvetrain with intake variable cam timing and it has been designed to accommodate advanced technologies, including gasoline direct injection and turbocharging, according to Ford. The engine will be built starting in the fall of 2006.

The new V6 will be mated to a new six-speed on the Edge and Aviator. Ford says enhanced performance and fuel economy of the new 6F comes from a wide span of 6.04 between the transaxleâ€™s lowest and highest gear ratio. The high ratio span helps deliver improved fuel economy of up to 7 percent and improved sustained acceleration compared with a typical 4-speed automatic, according to the automaker.

BELOW IS MORE FROM THE FORD PRESS RELEASE ABOUT THE NEW 3.5-LITER:

A Solid Foundation â€“ Durability and NVH
Every world-class engine starts with a solid foundation. To optimize the base engine structure to provide outstanding durability and NVH, the lower-end design of the 3.5-liter engine features a forged-steel, fully counterweighted crankshaft with induction-hardened journals, fractured-split, powder metal-forged connecting rods and high-temperature alloy, cast aluminum pistons. These components are housed in a High Pressure Diecast (HPDC) aluminum cylinder block featuring six-bolt mains with cast in cast-over iron liners.

The engineâ€™s cylinder block design represents the first application of a high-pressure die-cast block for a V-configuration engine for Ford Motor Company. Ford chose HPDC over more conventional semi-permanent and sand casting processes because:

* Reduced raw material requirements (lower weight than if designed for conventional sand casting)
* Tighter casting process control capability
* Better and more consistent casting qualities
* Elimination of reliance on casting processes that have byproducts requiring strict environmental controls
* Reduction of expensive post-casting processing (cleaning, heat treating, machining and assembly) requirements

Ford deployed extensive CAE modeling to reduce lead-time, optimize die design and simulate critical process parameters to help ensure a consistent, robust casting.

High Airflow, Optimized Combustion â€“ Performance, Fuel Economy and Emissions
The 3.5-liter V-6â€™s upper-end was designed as a system, all the way from the throttle body to the exhaust manifolds, to create the optimum flow for peak power and a broad torque curve. CAE analysis was used to fine-tune each component to deliver the required airflow without the need for intake flaps or butterfly valves in the system. Advanced throttle-control software enables precise tuning of engine response to fit the character of each vehicle application while setting the engine to run at its peak efficiency for optimal fuel economy.

The 3.5-liter V-6 uses a compact, lightweight dual-overhead cam valvetrain for peak power capability and smooth operation at high RPMs. The engine also incorporates intake variable cam timing (iVCT) to optimize valve timing for a smooth idle, optimal part-load driving and an impressively broad torque curve with good power. The iVCT system uses a hydraulically actuated spool valve that can rotate the intake camshafts up to 40 degrees within a half-second. A low-friction, roller-chain cam drive contributes to fuel efficiency.

Optimized Cylinder Head Produced with Flexible Machining
The aluminum cylinder heads in Fordâ€™s new V-6 are designed for high airflow and optimized combustion to support performance, fuel economy and low emissions. CAE was used extensively to develop the airflow and combustion system performance for this cylinder head design. This efficient combustion is enhanced by incorporating a centrally located spark plug and a high 10.3:1 compression ratio. The cylinder heads also were designed to accommodate fuel-efficient technology upgrades such as gasoline direct injection.

Low Emissions Capability
Fordâ€™s new 3.5-liter engine is PZEV capable right out of the box. Careful design consideration for the combustion system and catalysts create an engine that can meet stringent emissions standards without the need for expensive add-on technology.

â€œThe 3.5-liter V-6 is capable of achieving PZEV certification by delivering low cold-start emissions and enabling rapid catalyst light-off, which is a significant accomplishment for a larger displacement V-6 engine,â€ says Tom McCarthy, engine systems manager for the 3.5-liter V-6 engine program. This is accomplished with low heat-loss exhaust manifolds and close-coupled catalysts for fast light off during cold start. Optimized fuel injector targeting minimizes cold-start emissions before the catalysts reach operating temperature.

It's about time, still a bit behind the imports with their engines... with Nissan making up to 300hp with their 3.5, Toyota making 280hp with theirs (Avalon), etc...

and that's kinda funny cause you'd think that Ford is known for power on the big motors so kinda surprises me.

teevee247 · Nov 14, 2005

Well, on their V8's they make decent power... 300hp on a 4.8 is pretty decent... but... Nissan has 300hp on a 3.5 V6, theres the 3.5 V6 in the Avalon/IS350/GS350, etc... but at least Ford isn't resting on the 3.0 - 220hp V6... because its overclasses right now, even by Hyundai
