The 2.5 liter turbocharged five-cylinder engine that currently powers the Audi RS3 and Audi TT RS is among the most beloved engines on the market by most enthusiasts. Its power isn’t anything outrageous, as it makes 400 hp and 354 lb-ft of torque in both aforementioned cars. But what makes it special is how it delivers that power and most car enthusiasts love it. Thankfully, despite ever stricter-growing emissions regulations and fuel economy standards, the little turbo five-pot is going to stick around.
According to Audi Sport Boss Oliver Hoffman, who recently spoke with WhichCar, the 2.5 liter five-cylinder engine is going to stick around, even through tougher upcoming regulations. “It is more difficult, but it’s not just a question of how difficult it is,” Hoffman told WhichCar. “For EU7 (upcoming European regulations) we have concepts for all our engines, but it’s just a matter of how much money I have to spend to reach the targets!”
Apparently, Hoffman doesn’t mind spending money on the RS3’s five-pot. “For the five-cylinder we have a very, very, good concept to reach those standards.” he said.
It’s not just the performance or the popularity, though. Audi Sport feels strongly that the five-cylinder engine is a big part of its brand. The original Ur Quattro used a fiver after all. “For us, the five cylinder is so strongly combined with the heritage of Audi,” said Annette Möllhoff, product planner at Audi Sport. “It’s our number one USP in those models, and every time we launch a new model with the five-cylinder, we get the feedback that ‘we are so happy you stick to that engine and don’t downgrade to the four-cylinder’.” She said that it’s sometimes difficult to keep it around but that everyone at Audi Sport has the desire to do so. “It’s so emotional, and highly valued in the history of the company.”
This is great news. The current 2.5 liter turbo five-cylinder is one of Audi’s very best engines of all time. It’s wonderful noise, instant throttle response and overall sense of character make it delightful to use in any application. So we’re thankful that Audi is working hard to keep it around.[Source: Motor1]
