Audi is preparing to introduce a new 2.0-liter TFSI engine, claimed to be the most efficient gasoline engine in its displacement class.
The next-generation engine is said to use an “innovative combustion principle” that makes it “especially efficient” in real-world operating scenarios.
Additional details remain unclear, but the new turbocharged engine will be presented alongside the Q7 e-tron 3.0 TDI quattro at the Vienna Motor Symposium on Friday, May 8.
The next-generation engine is potentially a further refinement of the mill that helps power the new diesel hybrid’s gasoline-burning counterpart, the Q7 e-tron 2.0 TFSI quattro, which was unveiled at the Shanghai Motor Show. In both the standard Q7 and the gasoline hybrid, the engine is tuned to produce 252 horsepower and 273 lb-ft of torque.
The company is also working to bring its electric forced-induction technology to production vehicles, all but eliminating turbo lag. The electrically-driven compressor will be powered by a 48V electrical system, tied to a new alternator that serves both as a generator and an engine brake to help improve fuel efficiency. It is unclear if the next-generation 2.0 TFSI engine takes advantage of one or both technologies.
“We have been presenting our new drive technologies [at the Vienna Motor Symposium] regularly since 2009,” said Audi powertrain development head Dr. Stefan Knirsch. “One highlight was the four-cylinder TFSI with gasoline direct injection and turbocharging, which went on to become a successful engine worldwide following its introduction in 2007. The innovations that we are now showcasing in Vienna will add to this success story.”
