The Peugeot 407 SW - Engine Options | Part Six

Engines

All engine options offered in the saloon are also available in the SW.

Petrol Engines
All the petrol engines have four valves per cylinder and a motorised throttle housing which, controlled electrically by the engine’s electronic control unit (ECU), enhances driving comfort while at the same time reducing emissions. It also allows a dialogue between the engine and the ‘electronic stability programme’ (ESP).

1.8 litre petrol EW7 J4

With a capacity of 1,749 cm³ (bore 82.7 mm, stroke 81.4 mm), this engine develops a maximum power of 117 bhp at 5,500 rpm and a maximum torque of 120 lb ft at 4,500 rpm and offers 85% of torque from as little 1,500 rpm. The sequential multipoint injection and twin-static ignition coils are controlled by a SAGEM S2000 PL4 engine management system.

2.0 litre petrol EW10 J4

With a capacity of 1,997 cm³ (bore 85 mm, stroke 88 mm), it develops a maximum power of 138 bhp at 6,000 rpm, and maximum torque of 143 lb ft at 4,100 rpm.

Management electronics comprise a Magneti Marelli 48 P sequential injection engine management system and a SAGEM BBC 2.2 twin-static coil ignition system.

2.2 litre petrol EW12 J4

With a capacity of 2,230 cm³ (bore 86 mm, stroke 96 mm), it develops maximum power of 160 bhp at 5,650 rpm, and maximum torque of 163 lb ft at 3,900 rpm, 92% of which is available between 2,000 rpm and 5,500 rpm. To reduce the natural vibrations transmitted by a 4-cylinder engine during acceleration, this engine is equipped with two balance shafts driven by the crankshaft. To encourage a high torque at low engine speeds, the intake camshaft is equipped with a variable timing system (On/Off, VTC) offset by up to 20° with respect to the crankshaft. Engine management is by means of a type 4 MP Magneti Marelli unit controlling a phased sequential injection and an ignition, also sequential, with one ignition coil per cylinder.

3.0 litre petrol ES9 A

This V6 engine with a capacity of 2,946 cm³ (bore 87 mm stroke 82.6 mm) develops maximum power of 211 bhp at 6,000 rpm and maximum torque of 218 lb ft at 3,750 rpm.

To obtain good flexibility at low engine speeds and power, the intake camshafts are equipped with a variable valve timing system (VVT) with an angular variation of between 0° and 40° with respect to crankshaft timing.

This is carried out one degree at a time and allows optimal filling of the combustion chambers regardless of engine speed. This characteristic makes the engine both flexible and powerful. Engine management is by means of a Bosch M4 7.6 unit with a phased sequential injection and an ignition system using six individual 'pencil' ignition coils.
