Audi has bolstered the A6 lineup with all new versions of the S6 and S6 Avant. The big news is the replacement of the 5.2L V10 engines in earlier models with a new engine, a 4.0L, twin-turbo V8. The engine is part of Audi’s corporate philosophy of engine downsizing without compromising performance. The program combines impressive power and better performance with low fuel consumption. Initial reports show a 25% reduction in fuel consumption.
The S6 and S6 Avant use the same twin-turbo 4.0L TFSI engine found in the range topping S8 but in a de-tuned 420 hp version. The new twin turbine enhanced V8 provides a constant 406 lb-ft of torque starting at 1,400 all the way up to 5,300 rpm. The new S6 will bolt from a standing start to 100 km/h in 4.8 seconds while the Avant model takes a bit longer at 4.9 seconds.
The smaller displacement is not the only reason the new S6 yields a better fuel consumption rating, the new vehicle also incorporates variable displacement technology which shuts down the cylinders in uses depending on engine load, in addition to stop start technology. The new S6 sedan is now rated in Europe at just 9.7 liters per 100 km and 9.8 liters in the S6 Avant.
As one would expect the new S6 comes standard with the latest version of Audi’s legendary Quattro all-wheel-drive system.
Look for a complete road test in the new year.
