The 2019 Audi S6 emerges as a compelling choice in the realm of four-door vehicles, masterfully blending luxury, refinement, and exhilarating performance. It confidently ticks all the boxes for those seeking a versatile car that doesn’t compromise on driving pleasure or efficiency. Surprisingly, the key to its appeal lies in its modern diesel engine, defying any preconceptions about older diesel technology.
2019 Audi S6 Avant TDI Engine with Electrically Powered Compressor
Under the hood of the 2019 Audi S6 resides a potent 3.0-litre TDI V6 engine, sharing its foundation with the A6 50 TDI. This advanced diesel unit is augmented by a mild-hybrid system, intelligently capturing and redeploying energy to enhance efficiency. Officially, the S6 achieves an impressive 36.2mpg and emits 164g/km of CO2, figures closely mirrored by the S7 variant. However, the true innovation lies in the integration of an ‘electrically powered compressor’ (EPC), a technology also featured in the SQ7 SUV. This EPC acts as an electric supercharger, delivering instant boost at low RPMs, effectively eliminating turbo lag. This ingenious system works in tandem with a larger turbocharger, ensuring responsive performance even at lower speeds. The combined result is an output of 344bhp and a substantial 700Nm (516lb ft) of torque. This translates to a brisk 0-62mph sprint in just 5.0 seconds. While boasting slightly less outright power than previous petrol S6 models, the 2019 diesel S6 compensates with significantly more torque and exceptional fuel economy, potentially offering over 620 miles on a single tank for those prioritizing efficiency.

Despite the expectation of immediate and forceful power delivery thanks to the EPC, a slight hint of lag remains. Drivers who enjoy pushing engines to their redline might find the diesel S6 feeling somewhat restrained at higher revs. However, the true strength of the 2019 Audi S6 engine lies in its devastatingly effective mid-range performance. The optimal power band resides between 2,000 and 3,500rpm, and the seamless eight-speed automatic transmission ensures the car consistently operates within this sweet spot. Whether in second, third, fourth, or fifth gear, the performance feels relentlessly strong and responsive, making overtaking and spirited driving effortless.
Contrary to expectations of compromised handling due to its size and luxury focus, the 2019 Audi S6 chassis proves to be remarkably engaging and agile. Audi’s renowned Quattro all-wheel-drive system provides exceptional sure-footedness, while the chassis itself exhibits surprising nimbleness. The test vehicles were equipped with optional rear-wheel steering and a sport rear differential, further enhancing handling prowess. An S7 variant was also tested with optional carbon-ceramic brakes, showcasing truly remarkable stopping power, although likely an extravagant option for most buyers.

Regarding ride comfort, the optional air suspension, tested on German roads, felt somewhat overly soft. The standard coil spring setup offered a more controlled and firm ride, while still maintaining ample compliance for everyday driving. For UK roads, the standard suspension configuration is likely the preferred choice. Ultimately, choosing the 2019 Audi S6 involves deciding between three appealing body styles: the S6 Saloon, the practical S6 Avant, and the stylish S7 Sportback four-door coupe. While all are highly desirable, the understated Audi S6 Avant arguably best embodies the do-it-all nature of the turbodiesel S concept, offering a compelling blend of performance, luxury, and practicality.
