The new 2.0 TSI engine of the ŠKODA OCTAVIA RS is based on the power unit of the previous generation’s OCTAVIA RS 245. Further development of the engine focused on maintaining its dynamic characteristics and maximum output of 180 kW (245 PS) while making it even more efficient. This was achieved, among other things, by increasing the fuel injection pressure up to 350 bar, and by using newly shaped piston crowns and a new crankshaft seal to reduce friction and, therefore, fuel consumption. Furthermore, the ŠKODA engineers modified the exhaust gas routing as well as the ignition system.
The technology of the 2.0 TDI delivering 147 kW (200 PS) is similar to that of the other EVO generation diesels, producing either 85 kW (116 PS) or 110 kW (150 PS). The 2.0 TDI features, however, an aluminium cylinder block and aluminium pistons with low-friction piston rings. In addition to that, it comes with different connecting rods, where the diameter of the journals is now 54 instead of 48 mm. The turbocharger is water-cooled for improved temperature regulation, and its compression ratio is higher.
