Chronology
Predecessor Ford Duratec V6

The Cyclone engine is Ford Motor Company's latest DOHC V6 family of gasoline engines introduced in 2006.[1]

The Cyclone engine succeeds Ford's previous V6 engine families, the Ford Essex engine introduced in 1981, the Ford Vulcan engine introduced in 1985, the Duratec V6 introduced in 1993, and the Ford Cologne V6 engine, whose original design dates back to 1962. The first version of the Cyclone engine, a 3.5 L V6, appeared in the 2007 Lincoln MKZ. Mazda badges its versions of the Cyclone MZI as it did with its versions of the Duratec V6.

Notable Cyclone features include a capacity for displacements ranging up to 4.0 L,[1] DOHC 4-valve per cylinder heads, direct acting mechanical bucket (DAMB) camshaft tappets, variable cam timing (iVCT) on the intake camshafts, and twin-independent variable cam timing (Ti-VCT) on some later versions. Features such as Gasoline direct injection and turbocharging were considerations in the design phase and have been added to the engine as part of EcoBoost. The 3.5 L is ULEV-II compliant and is capable of meeting the PZEV requirement.

3.5 L

The Duratec 35 displaces 3.5 L (3496 cc, 213 CID) with a 92.5 mm (3.64 in) bore and 86.7 mm (3.41 in) stroke. Due to packaging differences (primarily the relocation of the water pump to the valley), the 3.5 L engine will fit into any engine bay the smaller Duratec 3.0 L will, and replaced it in some applications (notably the Ford Taurus) in the 2008 model year. Production began in 2006 for the Ford Edge, Lincoln MKX, and Lincoln MKZ.

Official SAE certified engine output is 265 hp (198 kW) and 250 lb·ft (339 N·m) on 87 octane gas. This is a substantial upgrade in power from the Duratec 30 and bested all comparable 87 octane rated V6 engines at the time of its launch.[2] For 2011, the 3.5 L received Ti-VCT, helping to boost output to 285 hp (213 kW) and 253 lb·ft (343 N·m).[3] The 3.5 L's highest output to date is 290 bhp (216 kW; 294 PS). This version was used in the redesigned 2011 Ford Explorer.

The engine is assembled at Lima Engine in Lima, Ohio, with expansion planned in Cleveland Engine Plant #1.

The 3.5 L was on the Ward's 10 Best Engines list for 2007.

EcoBoost

Main article: Ford EcoBoost engine

It is a twin turbocharged, gasoline direct injected (GTDI) version of the 3.5 L.

3.7 L

The Duratec 37 is a 3.7 L (3726 cc/227 CID) version of the Cyclone V6 intended to power heavier or premium vehicles. The 3.7 L's additional displacement comes from an increase in bore diameter to 95.5 mm (3.76 in), stroke remains identical to the 3.5 L at 86.7 mm (3.41 in). Ford Power Products sells this engine as the CSG-637 for industrial uses starting in mid-2015, which replaced the 4.2L Essex.

A Hiroshima, Japan assembled Mazda MZI 3.7 was installed in the 2008 Mazda CX-9 and was the first 3.7 L Cyclone V6 to see production. The first Ford application of the 3.7 L was the 2009 Lincoln MKS.

A few days before the 2009 Los Angeles International Auto Show, Ford unveiled a new version of the 3.7 L for the 2011 Mustang, making it the first Duratec-badged V6 since the Lincoln LS to be used in a production rear-wheel drive car. This version of the 3.7 L features Twin Independent Variable Cam Timing (Ti-VCT); delivers 31 mpg-US (7.6 L/100 km; 37 mpg-imp) highway mileage in the Mustang, and was the first production engine to deliver in excess of 300 hp (224 kW) and 30 MPG.[4]
