Peugeot 407 diesel coupe 2006 review

In the past, these engines were fairly rudimentary, barely more refined than something lifted from a commercial vehicle.

Not now.

The latest addition to Peugeot's diesel lineup is a high tech, twin turbo, common rail 2.7-litre V6 that's available in the elegant 407 Coupe. It will soon be available in the nearly as appealing 407 sedan and wagon.

Presumably, the 2.0-litre four cylinder turbo diesel currently available in the latter two will remain in the lineup as well as the 3.0-litre V6 petrol.

But who'd want the petrol V6 engine when the diesel is so much better in every way and it's the first diesel coupe ever offered on the Australian market.

It sounds better, offers a huge amount of torque and consequently stronger acceleration, uses minimal fuel and complies with the stringent Euro4 emissions regulations.

Did I mention that it's hooked up to a smooth shifting six speed automatic transmission.

The V6 diesel is virtually the same engine in the new Jaguar S-Type diesel but that vehicle costs tens of thousands more than the 407 Coupe diesel at $72,500. It's good for 150kW/ 440Nm output from as low as 1900rpm.

Put into perspective, this amount of torque is produced by self respecting V8 petrol engines of nearly twice the capacity.

The car itself is handsomely equipped with the usual luxury features but some relatively unusual stuff too.

Directional bi-xenon headlights that look around the corner are included in addition to cruise control with a speed limiter to keep you legal, front and rear parking sonar so you don't dent the model, premium hi-fi to groove to, automatic headlights and wipers for when you're feeling lazy and heated front seats to keep your butt warm.

The Coupe scores a five star NCAP crash test rating which means cutting edge safety inclusions like Electronic Stability Program, ABS and multiple air bags.

It's a big coupe, almost the same size as Monaro but with much more presence on the road.

Plenty of room is provided for four inside the cabin and the boot is large for such a car.

As expected, the Coupe has a composed ride offering smooth supple suspension or alternately, firmer sporty dynamics at the touch of a button. The same applies to the transmission with an "S" for sport mode and sequential change.

It's quiet inside like a luxury car should be and the pampered feeling extends to the seats, leather upholstery and all other interior features. Access to the rear seats is through long doors which can be an issue in tight parking.

The diesel 407 Coupe is great to drive offering sporty performance and excellent roll- on acceleration at will. Fuel economy hovers around the 7.5-litres/100km mark and it doesn't sound half bad either.
