TSI of the Golf R
The EA113 series direct-injection petrol engine is used in the new Golf R; its turbocharger makes it very flexible and variable right up into the highest performance ranges. The 1,984 cm3 TSI’s specific power is a respectable 100.3 kW / 136.6 PS per litre displacement, and its response is just as impressive. The engine’s power can be spontaneously summoned in the blink of an eye throughout its speed range. The engine also impressively underscores its potential acoustically. Visually too: Its two chrome tailpipes can be seen at the centre of the bumper under the diffuser integrated there – an ‘R trait’ that the previous model also displayed.
The in-line four-cylinder engine develops its tremendous propulsive power via a turbocharger (up to 1.2 bar boost pressure) with inter-cooling. The engine, with a weight of just 152 kilograms, is controlled by a fully electronic engine management system with E-Gas. The cylinders of the four-cylinder engine have been equipped with reinforcing bolts, unlike less powerful TSI versions. Also designed to be stronger are the connecting rods, so that they can reliably transfer the engine’s high torque to the crankshaft. Last but not least the cylinder block was also reinforced to handle the aggressive engine forces.
