EA837 2.4 MPI uye 3.2 FSI injini

Muna 2004, injini dzemhuri yeEA835 dzakatsiviwa nemagetsi matsva eEA837 akatevedzana. Yekutanga chizvarwa injini yakagamuchira silumin cylinder block yatove isina liner uye yakanyanya kuomarara nguva yekutyaira: maketani mana, maviri epakati magiya uye chiyero shaft. Ese macamshafts aive nemafase regulators, uye manifold ekutora aive nemaseti maviri emadampers kamwechete.

Mutsetse wacho waive ne 2.4-litre injini ine yakajairwa jekiseni uye 3.2-litre yemukati inopisa injini ine yakananga jekiseni:
