1.6 TDI with 77 kW / 105 PS - The engine offering entry to the world of the Golf TDI consumes 3.8 l/100 km (equivalent to 99 g/km CO2) under standard NEDC conditions. Its maximum power is reached between 3,000 and 4,000 rpm, and its maximum torque of 250 Nm is available between 1,500 and 2,750 rpm. This TDI accelerates the Golf to 100 km/h in 10.7 seconds and reaches a top speed of 192 km/h. As an option, the Golf 1.6 TDI at this power level can be paired with a 7-speed dual-clutch gearbox. In this case, combined fuel consumption is 3.9 l/100 km (equivalent to 102 g/km CO2).

1.6 TDI with 81 kW / 110 PS - The Golf BlueMotion achieves a combined fuel consumption of 3.2 l/100 km (equivalent to 85 g/km CO2); this makes it the most fuel-efficient Golf ever. Its maximum torque of 250 Nm is available from 1,500 to 2,750 rpm. The new Golf BlueMotion has a top speed of 202 km/h and if necessary can accelerate to 100 km/h in 10.5 seconds. The Golf BlueMotion is exclusively offered with a 5-speed manual gearbox.

EA288 2.0 TDI with 110 kW / 150 PS - A combined fuel consumption of just 4.1 l/100 km (106 g/km CO2) is an excellent value for an engine with 150 PS of power. The 2.0-litre TDI also has two balancer shafts and so it runs very smoothly

2.0 TDI with 110 kW / 150 PS- A combined fuel consumption of just 4.1 l/100 km (106 g/km CO2) is an excellent value for an engine with 150 PS of power. The 2.0-litre TDI also has two balancer shafts and so it runs very smoothly. It develops its maximum power between 3,500 and 4,000 rpm; from a low 1,750 rpm the TDI makes its maximum torque of 320 Nm available (up to 3,000 rpm). The Golf 2.0 TDI has a top speed of 216 km/h and accelerates to 100 km/h in 8.6 seconds. This Golf may also be ordered with an optional dual-clutch gearbox (6-speed DSG). In this case, the car’s combined fuel consumption is 4.4 l/100 km (equivalent to 117 g/km CO2).

Technical details of the new EA288 series diesel engines

New level of sustainability. In the EA288 engine series, Volkswagen is taking its TDI technology - which has been continually perfected over the years - to a new level of sustainability. Consider the Golf 2.0 TDI with 110 kW / 150 PS: Compared to the previous engine (EU-5 engine of the EA189 series with 103 kW / 140 PS), which was already extremely fuel efficient, fuel consumption was further reduced by 0.2 liter, and CO2 emissions were reduced by 8 g/km.

 Many components were designed to be modular thanks to the new modular diesel component system (MDB). They include emissions-relevant components such as the fuel injection system, turbocharger and intercooler within the induction manifold module.

Internal engine modifications to reduce emissions. Just like the new petrol engines (EA211), the only dimension of the Golf’s new four-cylinder diesels that is the same as that of the previous model is the cylinder spacing. Many components were designed to be modular thanks to the new modular diesel component system (MDB). They include emissions-relevant components such as the fuel injection system, turbocharger and intercooler within the induction manifold module. In addition, a complex exhaust gas recirculation system is used (with a cooled low-pressure AGR). Also new on all Golf TDI engines is the layout of emissions control components to locate them nearer to the engine. To fulfill various emissions standards worldwide, the emissions control components oxidation catalytic converter, diesel particulate filter and NOx storage catalytic converter are implemented in the Golf. Various other design modifications optimize fuel economy and comfort significantly as well.

Low-friction bearings and oil pump with volumentric flow control reduce friction. Along with reducing hazardous emissions, Volkswagen has tuned all sub-assemblies of the new TDI for minimal internal friction. These actions include piston rings with less pretension and the use of low-friction bearings for the camshaft (drive-side) and - in the top version - for the two balancer shafts. In the oil circulation loop, energy usage was optimized by an oil pump with volumetric flow control.

Quickly up to temperature. During the warm-up phase, an innovative thermal management system utilizes separate cooling circulation loops for the cylinder head and the cylinder crankcase as well as a deactivatable water pump. This heats the TDI engines of the new Golf to their operating temperatures considerably faster. A pleasant side effect: the interior also gets warmer quicker in the winter. Another independently controlled cooling loop enables on-demand control of charge air temperature with additional emissions control benefits.

Balancer shafts for the 2.0 TDI. The new diesels are not only very low in emissions, fuel-efficient and torque strong, they are also very smooth-running and comfortable. Consider the 2.0 TDI with 150 PS: two low-friction bearings are used in its balancer shafts. They eliminate free inertial forces that occur in any piston engine system.
