Citroen has been sincerely working on new, fuel efficient engines for a really long time and the outcome is the PureTech family. The PureTech family of engines was first launched in 2012 and in the past two years it has grown bigger. Citroen has started introducing the new PureTech engines on its new generation models and Citroen C4 is the latest one to get it.
The 2014 Citroen C4 will be available with a new 3-cylinder e-THP 130 PureTech engine which features technologies like a direct-injection turbocharger and variable valve timing. Talking in terms of performance, the new e-THP 130 engine is capable of putting out 130 hp of max power available at 5,500 rpm and peak torque of 230 Nm available from 1750 rpm.
Compared to the current 4-cylinder engine options available on the C4, the PureTech heart offers increased efficiency and reduced CO2 emissions. The 4-cylinder engine emits 143 g/km whereas the new 3-cylinder PureTech engines returns an appreciable 110 g/km. The engine also comes with a latest-gen high efficiency turbocharger which delivers 95 percent of the torque between 1500 rpm and 3500 rpm.
What helps the new engine become so capable are a couple of components which have been reinforced specifically for this engine. To name some, there is a aluminium-copper alloy cylinder head, a strengthened die-cast crankcase, a steel crankshaft and others. Before the engine made it to Citroen models, it went through 25,000 hours of rigorous testing and was driven 1.6 million kilometers.
As far as the eco-friendliness is concerned, the Citroen C4 e-THP 130 emits just 110 g/km of CO2 and consumes 4.8 liters of fuel per 100 km.
