A8 engines
The lightweight aluminum design and advanced FSI technology of the 4.2 liter FSI® V8 engine creates a balance that allows for increased efficiency, improved vehicle dynamics and impressive power delivery. This powerful engine propels the A8 from 0-60 in just 5.7 seconds.
| 4.2 FSI® Specs | |||
|---|---|---|---|
| Horsepower | 372 hp @ 6800 RPM | ||
| Torque | 328 lb-ft. @ 3500 RPM | ||
| A8 | A8 L | ||
| 0-60 MPH | 5.7 sec. | 5.8 sec. | |
