[Peugeot-L] It gets up to 70 MPG if I'm doing the math right

Climate-change weapon - Peugeot 307 HDi
02 May 2006

NZ Autocar'a Peter Louisson takes a look at a little Pug with a big heart.

With fuel prices continuing to rise and the planet's thermostat officially malfunctioning, compact cars and those with an environmental bent are suddenly in vogue. Not before time.

Good timing also for those with high-tech diesels, now that lowsulphur  fuel is available at the pumps.

Enter the facelifted Peugeot 307 HDi. With its diesel particulate filter it is as environmentally friendly as a hybrid, but without their inherent compromises.

Forget the facelift per se; you have to look hard to spot the 600 differences. But the drive is vastly improved, primarily as a result of its new high-tech common-rail turbodiesel. The five-speed manual version costs $36,990, placing it at the upper end of the Corolla/Mazda3/Focus class. But what other manufacturer (Citro?aside -  OK, Golf and Skoda too) offers a diesel engine in this class, and a diesel engine that happens to be one of the world's best?

What makes it spectacular is its size: the new unit displaces just 1.6 litres, and yet it creates more power (80 versus 66kW) and a truckload more torque (260 versus 205Nm) than its 2.0 litre forebear. Having an intercooler helps. Being smaller in displacement, it uses less gas, and with its new particulate filter, there's not even a wisp of blue smoke from the tailpipe. Nor is the characteristic diesel smell any more noticeable than the pong of petrol.

The particulate filter self-regenerates every 800-1000km. When pressure starts to build up, it burns off the carbon trapped in the silicon carbide core using a process that goes unnoticed by occupants. The filter needs replacing every 250,000km. So fitted, the new 307HDi meets EU IV emissions standards, and pokes out under 120g/km of CO2. It rids exhaust gases of over 95 per cent of soot (carbon and sulphur) particles, pollutants associated with bronchitis, among other problems.

While it is about as 'green' as a hybrid, it still goes hard; hence the 'mean and green' tag line. Peugeot reckons on around 12.3 seconds for 0-100km/h, but we aced this figure, with a best of 10.57s, and it can clear out from traffic at the lights with little effort. It creates peak torque at around 100km/h in top gear so is breezy to drive on the open road. I'd rather it had cruise control than a remote audio device for this reason.

What makes the Pug engine so user-friendly is that it torques up a storm, offering good shove from 1500rpm, so short-shifting (change up a gear at 2500rpm) is the order of the day. Which makes it easy on fuel; the trip computer suggested averaged diesel consumption of 5.8L/100km, with a claimed mean of 4.8, and a best of 4.2 on the open road. We saw figures of 3-4L/100km at a constant 100km/h, so the quoted best figure is credible. It's quiet too, as modern diesels tend to be.

Okay, some aspects of the 307 aren't quite as praiseworthy. Auto lovers won't much like the five-speed manual gearbox (auto is not an option but a self-shifting 2.0 litre HDI is coming later in the year), the drinks' holders are a bit useless, and the specification is patchy. I could live without the niceties of dual-zone air con, and auto-on lights and wipers, say, if the more logical cruise control featured.

But what is a car without heart? This new engine is simply as good as diesel gets at present. Good enough, in fact, that this engine will power the new Mini and BMW 1 Series in the future.

The fact the car has a sweet ride/handling package is neither here nor there: you expect that of a Peugeot. It also steers beautifully - once more with feeling - like many others in the class don't. It resists understeer almost like it's illegal.
