1.0 PureTech vs Porsche M96/M97: which engine is more reliable?
According to our risk index, the Porsche M96/M97 carries less risk than the 1.0 PureTech: 50/100 versus 59/100 (both high risk). The 1.0 PureTech has 2 documented serious faults, the main one being «Excessive oil consumption through the piston rings»; the Porsche M96/M97 has 4 documented serious faults, the main one being «Failure of the intermediate shaft bearing (IMS) on the M96/M97».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.0 PureTech reliable?
It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.[1][2][3][4]
See the 3 of the 1.0 PureTech faultsIs the Porsche M96/M97 reliable?
It depends on the version: the M96/M97 has a reputation as a fragile engine because of the IMS bearing, scored cylinders and the rear crankshaft seal, but sources disagree on how many fail and none gives a verified statistic. The most exposed are the 986 and 996 from 1999-2005; the 997.2 and 987.2 from 2009 left this behind with the MA1 engine.[5][6][7][8]
