VW 1.9 TDI Specsby Justin Cupler
Volkswagen placed its 1.9-liter turbocharged direct injection (TDI) engine in several different models throughout the 1990s and 2000s---primarily the Golf and Jetta. The TDI engine underwent one upgrade in 2003, when it received a pump-style fuel injection system. Volkswagen eliminated the 1.9-liter engine in 2007. The TDI name returned in 2009, however, with the 2.0 TDI in the Jetta.
From 1996 through 2003, the 1.9-liter TDI created 90 horsepower (hp) at 3,750 revolutions per minute (rpm). In 2004, Volkswagen tweaked the fuel injection system, after which the 1.9-liter TDI produced 100 hp at 4,000 rpm.
From 1996 through 2003 the 1.9 TDI produced 155 foot-lbs. of torque at 1,900 rpm. In 2004, the torque jumped to 177 foot-lbs. at 1,800 rpm. It remained there until the engine's discontinuation after the 2006 model year.
The engine's fuel economy varied slightly, depending on the vehicle in which Volkswagen installed it. It got 32 to 41 miles per gallon (mpg) in the city and 41 to 49 mpg on the highway.
Though output ratings and economy ratings varied throughout the years, the engine's basic configuration remained unchanged. It had a bore (cylinder width) of 3.16 inches and a stroke (piston travel inside the cylinder) of 3.76-inches. The engine had a total displacement of 1,896 cubic centimeters (cc). It had a 19-to-1 compression ratio and eight valves per cylinder. It was an overhead valve (OHV), four-cylinder diesel engine.
