Peugeot HDi Durability

Engine Durability

One of the more overlooked benefits of a Peugeot HDi diesel engine is its reliability and durability. This in turn leads to low engine maintenance, another area where HDi can be financially beneficial to you.

First, the nature of a diesel engine is to operate at much lower revs than a petrol engine, both for power and torque. Thus it doesn’t have to work as hard to get the maximum performance.

Second, there are fewer mechanical parts needed. Spark plugs, ignition coil, distributor and plug wires are all elements of petrol engines that aren’t used in diesels. Similarly, the FAP particle filter is virtually maintenance free, with its first service required at only 210,000km.

Finally, a diesel engine has a much lower exhaust temperature (approx. 450°C) than a petrol engine (approx. 1,000°C). This extends the life of the exhaust valves and the turbo charger.

24 Hours of Le Mans

Our first and second placings in the gruelling 24 Hours of Le Mans motor race in 2009 in a diesel powered car is testament to the durability and reliability of our HDi diesel technology. The same technology found in our 908 HDi FAP race car can be found in our road cars.
