EA111 or VW R4 engines
The VW EA111 line of 4-cylinder engines appeared in 1985 after the EA801 update. This family of power units has been so seriously upgraded several times that it is usually divided into five different series: transitional motors, as well as MPi, HTP, FSI and TSI.
Transition from EA801 series to EA111
In the 80s of the last century, the EA801 series engines began to be equipped with hydraulic lifters, which led to their rebranding and the emergence of a new family with its own name EA111. The cylinder spacing remained at 81 mm and the engine displacement was limited to 1.6 liters. But at first it was about more modest engines, the lineup consisted of engines from 1043 to 1272 cm³.
In many markets, only 1.3-liter engines, which were put on Golf and Polo, gained popularity:
1.3 MPI 8v (1272 cc, 75 x 72 mm), carburetor:
- MH (54 hp / 95 Nm) for VW Golf 2 (1G), VW Jetta 2 (1G);
- NZ (55 hp / 96 Nm) for VW Golf 2 (1G), VW Jetta 2 (1G);
These units have a modern design with a cast-iron 4-cylinder block and an aluminum 8-valve cylinder head with hydraulic lifters, which is located on top. The drive of the only camshaft here is carried out by a belt, and the oil pump by a chain.
Classic MPI motors EA111 series
Soon, the line of power units expanded significantly, and their volume increased to 1.6 liters. Also, 16-valve versions with a pair of camshafts are very widespread. All engines were equipped with multiport fuel injection, which is why they were often called MPi.
We have summarized the characteristics of the most common engines.

HTP 3-cylinder engine family
Separately, it is worth talking about a series of aluminum HTP units with only three cylinders. Engineers in 2002 created the perfect motor for a mini car, but it turned out to be unreliable. The owners were especially worried about the timing chain with a resource of even less than 100,000 km.
1.2 HTP 6v (1198 cc, 76.5 x 86.9 mm), injector:
- BMD (54 hp / 106 Nm) for Seat Ibiza 3 (6L), Skoda Fabia 1 (6Y);

- CGPA (70 hp / 112 Nm) for Seat Ibiza 4 (6J), Skoda Fabia 2 (5J);
FSI EA111 series power units
In 2000, the company’s engineers equipped the 1.4 and 1.6 liter engines with direct fuel injection. The first engines were based on the old cylinder block with a timing belt, but in 2003 a new aluminum block appeared, in which the belt gave way to the chain.
1.4-1.6 FSI 16v (1390 cc, 76.5 x 75.6 mm), direct injection:
- ARR (105 hp / 130 Nm) for VW Lupo 1 (6X);

- BAD (110 hp / 155 Nm) for Audi A2 1 (8Z), VW Bora 1 (1J);
- BAG (115 hp / 155 Nm) for Audi A3 2 (8P), VW Golf 5 (1K);
- BLF (116 hp / 155 Nm) for Audi A3 2 (8P), Skoda Octavia 2 (1Z);
TSI EA111 series power units
In 2005, probably the most massive Volkswagen engines were presented. The new 1.2 TSI turbo engines, as well as 1.4 TSI, incorporated the most modern technologies, but they became known not because of their innovation, but because of their very low reliability.
1.2-1.4 TSI 8v (1197 cc, 71 x 75.6 mm), direct injection:
- CBZA (86 hp / 160 Nm) for Audi A1 1 (8X), Seat Toledo 4 (KG);

- CTHA (150 hp / 240 Nm) for VW Jetta 6 (1B), VW Sharan 2 (7N);
Despite all the improvements, these motors never reached maturity and were replaced by the EA211 series. The reliable naturally aspirated engines of the EA111 range are still being assembled in developing countries.
