EA211 engines are a completely new four-cylinder turbocharged and direct-injection TSI engines. Compared to its predecessor, the EA211 series is significantly more compact, with installation length shorter, thus offering more interior space. The installation position of the engines has also been optimised. Just as in the diesels, the petrol engines are now mounted with the exhaust side facing backwards and tilted at an angle of 12 degrees. The weight of these petrol engines made of die-cast aluminium is only for the 1.2 TSI and for the 1.4 TSI. The crankshaft alone became lighter by 20 per cent; the connecting rods lost 30 per cent of their weight. In addition the connecting rod bearing journals are now hollow-drilled and pistons now come with flat bottoms, all of them optimized for lower weight. Regarding thermal management, the EA211 petrol engine is equipped with a modern dual-circuit cooling system. That means that a high temperature circuit with a mechanically driven cooling pump cools the basic engine, while a low temperature circuit flows through the intercooler and the turbo-charger casing. The cylinder-head circuit heats the cabin's interior. The exhaust manifold is integrated into the cylinder head, enabling the engine to warm up more quickly, in turn making heat available quickly for the passenger cabin. At high loads, the exhaust is cooled by the coolant, lowering fuel consumption. EA 824, EA 825 EA 824 and EA 825 are families of twin turbo 90 degrees V8 spark ignition engines. Audi uses the EA 824, while Porsche uses EA 825 for Panamera Turbo. EA 825 uses two twin-scroll turbochargers, iron coating on the cylinder linings, fuel injector at centre of combustion chamber, cylinder deactivation at 950-3500rpm with a torque limit. EA 839 EA 839 is a family of turbocharged 90 degrees V6 spark ignition engines. It includes steel cylinder liners, balancer shaft located within the vee, maximum compression ratio of 11.2:1, bore and stroke of . EA888 The EA888 engines are a family of three and four-cylinder engines that are currently in use across the Volkswagen Group. An EA888 family is a corporate VAG designed unit that is an evolution of the earlier EA827/113 units. It features some of the latest engine technology such as direct fuel injection, sintered camshaft lobes, thin-walled engine block, variable valve timing and lift for intake and exhaust valves, downstream oxygen sensors, exhaust manifold integrated into the cylinder head, exhaust gas recirculation
