(EA839) The base engine is the 3.0 TFSI, available on Audi S4/S5/SQ5 models and a slightly detuned version () with 48V mild hybrid system on various Audi models such as the A6, A7, A8, Q7 and Q8. The 2.9 TFSI engine is a shorter stroke variant with much higher output. identification parts code prefix:???, ID codes: CWGD, CZSE/DR, DECA engine displacement & engine configuration 3.0 TFSI variant: 90° V6; bore x stroke: , stroke ratio: 0.94:1 - undersquare/long-stroke, compression ratio: 11.2:1 2.9 TFSI variant: 90° V6; bore x stroke: , stroke ratio: 0.98:1 - undersquare/long-stroke, compression ratio: 10.0:1 to 10.5:1 depending on models cylinder block & crankcase sand-cast Alusil aluminium-silicon alloy; atmospheric plasma sprayed coating on cylinder walls cylinder head & valvetrain cast aluminium alloy; four valves per cylinder, 24 valves total, DOHC, continuous timing adjustment on both intake and exhaust camshaft(from 130 degrees up to 180 degrees), 2-stage(6mm and 10mm) Audi Valvelift System(AVS) on the intake sides aspiration all variants feature both Otto and Miller cycles, achieved from valve timing; hot-film air mass meter; electronic drive by wire throttle valve; exhaust manifold integrated into cylinder head; hot-V configuration 3.0 TFSI: twin-scroll single-turbo charged 2.9 TFSI: twin-turbo charged fuel system common rail Fuel Stratified Injection (FSI) high-pressure direct injection DIN-rated motive power & torque outputs, ID codes 3.0 TFSI variants at 5,400-6,400 rpm; at 1,340-4,900 rpm - unknown/Porsche variant at 5,000-6,400 rpm; at 1,370-4,500 rpm - CZSE(2017-2018)/DR(2019-) at 5,400-6,400 rpm; at 1,370-4,500 rpm - CWGD 2.9 TFSI variants at 5,250-6,500 rpm; at 1,750-5,000 rpm - unknown/Porsche variant at 5,650-6,600 rpm; at 1,750-5,500 rpm - unknown/Porsche variant at 5,700-6,700 rpm; at 1,900-5,000 rpm - DECA production Audi Hungaria Zrt. in Győr applications 3.0 TFSI(): Porsche Panamera/Panamera 4 (2nd gen) 2.9 TFSI(): Porsche Panamera 4 E-Hybrid (2nd gen) CZSE/DR: Audi A6 (C8), Audi A7 (C8/4K8), Audi A8 (D5), Audi Q8, Porsche Cayenne/Cayenne E-Hybrid (3rd gen), Volkswagen Touareg (3rd gen) CWGD: Audi S4 (B9, B9.5 excluding European models), Audi S5 (B9/F5, B9.5 excluding European models), Audi SQ5 (FY, excluding European facelited models) 2.9 TFSI(): Porsche Panemera 4S (2nd gen), Porsche Cayenne S (3rd gen) DECA: Audi RS4 (B9), Audi RS5 (B9/F5), Audi S6 (C8, excluding European models), Audi S7 (C8/4K8, excluding European models) references audi.de porsche.com volkswagen.de 3.2 VR6 24v This VR6 engine was often badged as a "V6" in Audi models identification parts code prefix: 022, ID codes: CBRA engine displacement &
