New 1.0 TGI (natural gas) and 1.5 TSI ACT (Active Cylinder Management)
Nine engines for the Polo. Volkswagen is equipping the Polo with a natural gas drive for the first time: the new 1.0 TGI with 66 kW / 90 PS can actually be CO2-neutral, depending on the energy source. The further developed 1.5 TSI ACT with Active Cylinder Management and 110 kW / 150 PS is one of the world's most advanced petrol engines. As soon as the driving situation allows, the four-cylinder engine deactivates two of its four cylinders to save fuel. The 1.0 TGI and 1.5 TSI ACT are two of a total of nine engines for the entirely front-wheel drive Polo. The five three- and four-cylinder petrol engines range from the 1.0 MPI with 48 kW / 65 PS to the 2.0 TSI with 147 kW / 200 PS. All petrol engines with up to 150 PS and the new natural gas drive belong to the efficient EA211 engine family. The 2.0 TSI engine comes from the third generation EA888 series with greater displacement. As a diesel, the Polo will launch with a choice of two 1.6 TDI engines whose outputs are 59 kW / 80 PS and 70 kW / 95 PS, respectively. Both four-cylinder engines belong to the EA288 engine family and have an SCR catalytic converter. All engines are equipped with a stop-start system and a regenerative braking mode. Any of the TSI and TDI engines with a power output of 95 PS or more can be configured with a highly efficient 7-speed DSG.

Natural gas in detail
1.0 TGI with 66 kW / 90 PS.. The first natural gas engine to be fitted in the Polo is a new development. The three-cylinder engine develops 66 kW / 90 PS from a displacement of 999 cm; this is available between 4,500 and 5,800 rpm. The efficient natural gas engine delivers its maximum torque of 160 Nm from a low 1,900 rpm (up to 3,500 rpm). The engine – which has a compression ratio of 10.5:1 like all EA211 engines – always starts in natural gas mode – as long as there is sufficient CNG on board. If the CNG in the safe high pressure tank is used up, the Otto engine switches to petrol fuel (RON 95). The total driving range of the Polo 1.0 TGI (Comfortline or Highline) is expected to exceed 1,190 kilometres.
Petrol engines in detail
1.0 MPI with 48 kW / 65 PS. The 1.0 MPI (Multi Point Injection) with 48 kW / 65 PS is the new entry-level Polo engine. Like all Polo petrol engines up to and including the 85 kW / 115 PS, this engine is also a three-cylinder engine which produces its power from displacement of 999 cm. In this case, the maximum power is available at 5,500 rpm. The maximum torque of 95 Nm is delivered between 3,000 and 4,300 rpm. When combined with a 5-speed gearbox, the 65 PS engine accelerates the Polo to 100 km/h in 15.5 seconds. Its top speed is 164 km/h. In the combined cycle, the Polo has fuel consumption of 4.8 to 4.7 litres (corresponding to 110 to 108 g/km CO2). The 1.0 TSI with 65 PS is offered in the Polo Trendline and Comfortline.
1.0 MPI with 55 kW / 75 PS. A 1.0 MPI with 55 kW / 75 PS is optionally available as the next power rating above the basic petrol engine. The three-cylinder engine reaches its maximum power at 6,200 rpm, and its maximum torque of 95 Nm is available between 3,000 and 4,300 rpm. With this engine the Polo reaches a top speed of 170 km/h and accelerates to 100 km/h in 14.9 seconds. Despite its extra power, the 75 PS engine that also comes with a 5-speed gearbox is just as fuel-efficient as the 65 PS version: 4.8 to 4.7 l/100 km (corresponding to 110 to 108 g/km CO2). The 75 PS engine can be ordered in the Polo Trendline and Polo Comfortline.
1.0 TSI with 70 kW / 95 PS. The smallest TSI for the new Polo has an output of 70 kW / 95 PS (at 5,500 rpm). The turbocharged engine, which is available as an option for the Polo Comfortline and comes as standard for the Polo Highline, is both agile and efficient. The three-cylinder engine with torque of up to 175 Nm (2,000 to 3,500 rpm) accelerates the Polo to 100 km/h in just 10.8 seconds. With a top speed of 187 km/h it reaches the level of the first Golf GTI. These figures apply to both the manual gearbox version and the optional 7-speed DSG version for this engine. The high agility is coupled with low combined fuel consumption of 4.5 to 4.4 l/100 km (corresponding to 103 to 101 g/km CO2). The 95 PS version with 7-speed DSG has a fuel consumption of 4.7 to 4.6 l/100 km and emits 107 to 105 g/km of CO2.
1.0 TSI with 85 kW / 115 PS. The most powerful 1.0 TSI / three-cylinder for the Polo is the version with 85 kW / 115 PS. This engine will be launched with a 6-speed gearbox as standard and optionally with a 7-speed DSG. The turbocharged direct injection engine develops its peak output at 5,500 rpm. The lively four valves per cylinder engine delivers its maximum torque of 200 Nm from 2,000 to 3,500 rpm. Like all other engines in the EA211 series it consumes premium unleaded fuel (95 RON). The 115 PS TSI will be available with a manual 6-speed gearbox and optionally with a 7-speed DSG.
1.5 TSI ACT with 110 kW / 150 PS.
The 1.5 TSI ACT with Active Cylinder Management is a high-tech engine for the Polo. It is a further development of the 1.4 TSI with ACT that was made its debut in the previous version. Depending on the operating situation, the Active Cylinder Management of the 1.5 TSI ACT can temporarily deactivate two cylinders, significantly reducing fuel consumption and emissions. The four-cylinder turbocharged petrol engine is exceptionally agile and refined. It develops its maximum torque of 250 Nm between a low 1,500 rpm and 3,500 rpm. The maximum power output of 110 kW / 150 PS is produced between 5,000 and 6,000 rpm. Like all EA211 units, this engine with displacement of 1,498 cm has a compression ratio of 10.5:1. The 1.5 TSI ACT has been significantly further refined compared with the 1.4 litre engine with ACT. For example, internal friction has been reduced thanks to a fully variable, map-controlled oil pump and a polymer-coated first crankshaft main bearing. In addition, the new turbocharged engine is characterised by higher injection pressures of 200 to 350 bar. Other refinements are the even more efficient indirect intercooling unit with improved cooling performance. Temperature-sensitive components such as the throttle valve are also located downstream of the intercooler for optimal thermal conditions. In addition, the new engine has a highly innovative thermal management system with a new map cooling module. Features: APS-coated cylinder liners, fin cooling between the cylinders and a cross-flow cooling concept in the cylinder head.
2.0 TSI with 147 kW / 200 PS. The new Polo GTI with 147 kW / 200 PS is scheduled to launch before the end of the year. The 2.0 TSI has 15 kW / 20 PS more power than the 1.4 TSI it replaces. Like the Golf GTI, the new Polo GTI will be represented in the 2.0-litre turbo class for the first time. The 1,984 cm engine has a compression ratio of 11.65:1. The GTI unit delivers its maximum power between 4,400 and 6,000 rpm. The third generation EA888 engine transfers its maximum torque of 320 Nm to the front axle from a low 1,500 rpm; this high torque figure remains constant up to a speed of 4,400 rpm. The new GTI engine will be available with a manual 6-speed gearbox as standard and optionally with a 6-speed DSG.
The diesel engines in detail
1.6 TDI with 59 kW / 80 PS. A 59 kW / 80 PS engine with 1.6 litres displacement offers entry into the world of the Polo TDI. The four-cylinder engine with a displacement of 1,598 cmbelongs to the EA288 diesel engine series. Like all TDI engines, it develops high torque at very low engine speeds: 250 Nm is produced over the speed range from 1,500 to 3,000 rpm. Its maximum power is available between 3,250 and 4,000 rpm. The 1.6 TDI with a compression ratio of 16.2:1 comes with a 5-speed manual gearbox.
1.6 TDI with 70 kW / 95 PS. The second TDI power unit among the EA288 engines develops an output of 70 kW / 95 PS between 3,250 and 4,000 rpm. Both 1.6 TDI engines share the same high torque of 250 Nm. Common rail fuel injection ensures very smooth and quiet combustion. Unlike the 80 PS version, the 95 PS TDI can be optionally ordered with a 7-speed DSG.
