AUDI’S NEW 2.0 TFSI ENGINE FOR NEXT A4

The down-sizing of engines is the new buzz word impacting the motor industry today helping automakers to reduce fuel consumption and emissions by employing methods like turbocharging and direct injection.

Audi, however, have adopted a new approach (revealed recently at the Vienna Motor Symposium in Austria).

Their new 2.0 TFSI produces140 kW (190 hp) and ground-breaking low fuel consumption of less than 5.0 litres/100 kms.

Audi was the first manufacturer worldwide to bring the TFSI engine with turbocharging and direct injection into series production ten years ago – trend setting in downsizing and down-speeding.

Their new method is now called ‘right sizing’ and involves the optimal interplay of vehicle class, displacement, output, torque and efficiency characteristics under everyday conditions. The new 2.0 TFSI is a prime example of ‘Vorsprung durch Technik.’ translated into English meaning ‘progress through technology’.

According to Audi ‘ the high torque is applied in a wide speed range of 1,450 to 4,400 rpm, every customer will benefit from the constantly accessible, high pulling power of the engine..

“The breakthrough of the 2.0 TFSI lies in a new combustion method. At its core its principle is comparable to the Miller cycle. Audi engineers have further developed that method in crucial ways……’

Dr. Stefan Knirsch, Head of Engine Development at Audi, sums up the benefits of the new engine: “Thanks to this right-sizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. The result is optimal efficiency and performance characteristics across the entire engine speed range.”

The new engine, with a weight of only about 140 kg and controlled greatly shortens the engine warm-up time and another contributing factor is a new exhaust manifold, integrated in the cylinder head. The consistent reduction of friction as well as the use of low-friction engine oil (0W-20) also increases efficiency.

The comprehensive package of high-tech solutions makes the new 2.0 TFSI a real high-efficiency engine setting a new benchmark in its segment. Audi will be introducing the new generation of engines first in the new Audi A4 in 2015, and then in other model series.
