PEUGEOT HAS GIVEN its stylish 407 Coupe a comprehensive mechanical upgrade for the 2010 model year, replacing the 2.7 litre HDi turbodiesel with a bigger, more efficient 3.0 litre unit and revising the 2.0 HDi diesel to boost power.
The new 3.0 V6 HDi PEF uses two turbochargers to produce its 177kW power rating, which is developed at a relatively low 3800rpm. More impressivley, peak torque of 450Nm is available from 1600rpm all the way to 3600rpm, endowing the big two-door with a substantial amount of grunt.
Not only is it more powerful than the smaller motor that it replaces, but it's more economical too. The 3.0 HDi PEF uses 7.2l/100km on the combined cycle and emits 189g/km of CO2 - not a bad figure for a 1600kg coupe. A six-speed tiptronic auto is standard equipment for the diesel V6.
The mid-range 2.0 litre HDi PEF inline-four has also been tweaked and now develops 20 percent more power than the outgoing 2.0 diesel. Peak power is now up to the 120kW mark, while torque has risen to a healthy 340Nm. Like the V6, the new 2.0 HDi goes easy on the juice too, sipping 5.4 litres of diesel per 100km and emitting 140 grams of CO2 per kilometre.
The 155kW petrol V6 carries over unchanged, but the entire 407 Coupe range benefits from a number of aesthetic improvements. Extra chrome trimming has been added to the side glass, the 3.0 HDi gets twin oval tailpipes and the wing mirrors are now larger to improve rearward visibility.
Sat-nav, Bluetooth connectivity and a USB audio input have also been added to the 407 Coupe's spec sheet.
It's not yet clear when the updated 407 Coupe will go on sale in Australia, however given the current unavailability of the 2.0 HDi in this market don't expect that model to be coming our way.
