Peugeot has launched two new diesel engines, both compliant with Euro IV regulations, one of which will find its way into a new 206 diesel GTi.

The first of these, the 1.6-litre HDi 110bhp, is an all aluminium unit with a variable geometry turbocharger and an air-air intercooler.  Maximum power is 110bhp at 4,000rpm, with torque of 180lb/ft at 1,750rpm.  An ‘over boost’ function allows a temporary torque increase to 192lb/ft when the engine is at full load between 1,500rpm and 3,750rpm.

This is the engine to be found in the new 206 GTi, Peugeot’s first diesel GTi, and identifiable by a red ‘i’ in the HDi badge.  This 206 will also be the first small car fitted with a particulate filter.

The 407 and 307 will also receive this new unit, replacing the previous 2.0 HDi 110 engine.

The second new engine is the new 2.0 litre HDi, a 16-valve DOHC with 136bhp at 4,000rpm and 240lb/ft at 2,000rpm.  Over-boost allows for a maximum temporary torque delivery of 251lb/ft.

The 2.0-litre will be available in the 407 range, the 307 XSi HDi and the 307 SW SE.

Both HDi engines, jointly developed with Ford, are equipped with the latest generation high-pressure “Common Rail” injection systems with an operating pressure between 250 and 1,650 bars, and particulate emission filters.
