The 3.0-liter turbocharged Audi CZSE 3.0 TFSI engine has been produced by the concern since 2017 and is installed only on the main modifications of the A8 sedan in the back of the D5 or the Q8 crossover. This motor is part of a hybrid power plant with a separate 48-volt network.
EA839 or Audi V6 TFSI engines
The Audi EA839 family of 6-cylinder V-shaped turbo engines has been produced since 2016 and is installed on especially powerful versions of many popular models of the German concern. These engines are divided into two series: with a single turbine of 3.0 liters and a bi-turbo of 2.9 liters.
EA839 3.0 TFSI engines
In 2016, power units of the EA839 family came to replace the turbo engines of the EA837 series. The changes were evolutionary, here is the same aluminum cylinder block with cast-iron liners, four camshafts rotate by chains and are equipped with phase shifters, there is a proprietary Audi Valvelift System or AVS. The compressor has given way to a Twinscroll turbine, which is located in the collapse of the block.
The unit works on the so-called Miller cycle and uses FSI direct fuel injection. There are not so many modifications yet, but their number is growing, the line is in the expansion stage:
- CZSE (340 hp / 500 Nm) for Audi A8 D5, Audi Q8 F1;
- DLZA (340 hp / 500 Nm) for Audi A6 C8, Audi A7 C8;
- CWGD (354 hp / 500 Nm) for Audi S4 B9, Audi S5 F5, Audi SQ5 FY.
EA839 2.9 TFSI engines
Simultaneously with the usual version of the turbo engine, a charged Biturbo modification appeared. The unit with a smaller piston stroke thanks to a pair of turbines develops up to 450 hp and 600 Nm.
So far, there are five versions of this engine, including modifications for Porsche cars:
The 3.0-liter Audi DLZA 3.0 TFSI engine has been assembled at the German company’s plant since 2018 and installed on the concern’s most massive mid-size models: the A6 and A7 in the C8 body. This unit is part of a hybrid installation with a separate 48-volt network.
The 3.0-liter Audi CWGD 3.0 TFSI turbo engine has been assembled at the concern’s factories since 2016 and is put on charged modifications of such popular models as the A4 B9, A5 F5 or Q5 FY. This power unit is the most powerful in its lineup and develops 354 hp and 500 Nm.
The 2.9-liter Audi DECA bi-turbo engine has been assembled by the German concern since 2017 and is installed only on the current generation of such charged models as the RS4 or RS5. A similar turbo engine is installed on the Audi S6 and S7 as DKMB or Porsche cars as MDC.AB.
