Rare inline five-cylinder engine


Five-cylinder engines are nothing new. As early as the last century, Volvo, Mercedes, Audi and other car companies have been involved (including gasoline and diesel), but the most representative today is undoubtedly the 2.5T inline of Audi. Five-cylinder engine.
Until 2009, Audi's 2.5T inline five-cylinder engine was mounted on the TT RS and RS3. Perhaps after this, the inline five-cylinder engine has gradually become synonymous with "performance".

It turns out that Audi's 2.5T engine has not disappointed everyone. From the data point of view, it has 400 horsepower and peak torque of 480N · m. Based on this, the RS3 100km acceleration time is 4.1 seconds and the TT RS 100km acceleration The time is 3.7 seconds. If you only talk about power output and stamina, the Audi 2.5T is still not as good as its own 2.9T V6 engine (450 horsepower, twin turbocharged), but from the control point of view, this 2.5T engine output is more linear and easier to control.
The Audi 2.5T engine has also repeatedly appeared on the "Ward Top Ten Engines" and "International Engine Awards" lists, and its technical strength is beyond doubt. But if you ask, if there are V6 engines with the same displacement and the same power level, how many people will stick to the five-cylinder engine?

The reason why the five-cylinder engine did not become mainstream is actually obvious. The first is the congenital structural reasons that everyone is worried about. Although the five-cylinder engine can perform as well as the six-cylinder engine, it still needs to work harder to suppress vibration and noise, which means that car companies will spend more time. , Energy, cost.

The second is the applicability of five-cylinder engines. For example, Audi's RS3 and TT RS are horizontal four-wheel drive layouts. In the future, it may be more straightforward and simple to use a six-cylinder engine, including the V6 and Z6.

Finally, four-cylinder and six-cylinder engines do have inherent advantages. For low- and mid-end models, four-cylinder engines are sufficient. For mid-to-high-end models, six-cylinder engines are the first choice.
