Peugeot PureTech 1.2 Engine Specs

The Peugeot PureTech 1.2 is the collective name for PSA Group's family of 1.2-liter turbocharged inline-three petrol engines produced since 2012, spanning several individual states of tune from 82hp naturally aspirated versions up to 155hp turbocharged, direct-injection variants (documented individually elsewhere in this database as the EB2, EB2DT, and EB2ADTX). As a family, PureTech engines represent PSA's core small-displacement strategy across the Peugeot, Citroën, DS, and Opel/Vauxhall brands, used in the 208, 2008, 308, 3008, C3, C4, and DS3, among many others.

Across the family, output spans from 82hp and 118Nm of torque in the simplest naturally aspirated tune up to 155hp and 240Nm in the most powerful turbocharged, direct-injection version, all built around a common DOHC architecture with PSA's VTi variable valve timing and a compression ratio around 10.5-11.0:1 depending on the specific variant. Being three-cylinder engines throughout the range, all PureTech variants share an inherent vibration characteristic at idle and low RPM that some drivers notice more than others, a normal trait of the three-cylinder layout rather than a fault.

Because "PureTech 1.2" spans naturally aspirated, turbocharged, and direct-injection variants with meaningfully different maintenance profiles, any specific example's characteristics depend considerably on which exact tune it uses. As a general theme across the family, the turbocharged direct-injection variants are prone to carbon buildup on the intake valves over high mileage, requiring periodic intake cleaning, and the turbocharger itself demands consistent, on-schedule oil changes to avoid premature wear - a more important consideration on these variants than on the simpler naturally aspirated version. Spark plugs, the timing chain, and general PCV system health should be part of routine maintenance across the entire family. Given PureTech's huge production volume across PSA's global brands, parts availability and mechanic familiarity are generally good across most markets where these vehicles are sold.
