This engine is now shared with many other Audi models, including the SQ5 TDI and the controversial downsized new S6 and S7 models. But we think the S5 is the best match for it, as many A5 3.0 TDI owners in the past said they would have liked a more powerful setup.
The TDI comes bundled up with the 48-volt mild hybrid technology that wasn't previously available on the smaller Audi models. We don't yet know if it has real benefits, but on paper, it sounds like a win-win. At 347 HP (255 kW), the power decrease versus the 3.0 TFSI is almost imperceptible. However, torque has gone up to 700 Nm (516 lb-ft), about 40% higher.
At the same time, it's claimed that fuel economy has improved 19%. Doing the 0 to 100 kph (62 mph) sprint in 4.8 seconds means you're a tenth of a second slower in the TDI. It's worth mentioning that both models have standard quattro AWD and an 8-speed automatic gearbox.
No cosmetic changes have been made to either of the models. However, we believe that a mild facelift will be introduced, slightly offset from the launch of the TDI engines, which is scheduled for next month. Prices will start from €65,300 for both body styles. The aging BMW 435d Coupe with 313 HP starts from €61,500 while Mercedes has no direct (diesel) rival at the moment.
