Audi upgrades entry level engines to deliver more power and economy. The two engines that will receive upgrades are 2.0 liter TDI diesel and 2.0 liter TFSI gasoline. The new 2.0 TDI will now produce 150 hp instead of previous 143 hp and maximum torque of 320 Nm between 1,750 – 3000 rpm. Audi has reduced friction with respect to the previous engine and balance shafts are installed on camshaft and needle bearings. The work of the oil pump is also optimized with a two-stage regulation which now has separate cooling circuits of the cylinder block and cylinder head with two different pumps which require the operation of only one phase in the warming. A radiator is integrated into the intake manifold and the exhaust gas re-circulation has been located near the motor to minimize losses.
In addition to the diesel engine, the new 2.0 liter TFSI produces 225 hp and has reduced consumption and emissions significantly. According to Audi the 2.0 liter TFSI with 6-speed manual transmission in combine cycle will deliver 5.9 l/100 km and Carbon Di-oxide at 138 gm/Km.
