While the Audi A6, A7 and Q8 all have several engine options worldwide, the best of the bunch is likely the 3.0 liter ‘TFSI’ turbocharged V6. It’s the same engine used in the Audi S4 and S5. It typically makes around 340 hp and 369 lb-ft of torque, depending on the model. However, ABT Sportsline has recently developed an engine tune that bumps power to over 400 hp, making these seemingly ordinary cars quite fast.
Just a simple engine tune, called ABT Power, is capable of making the engine in a humble Audi A6, A7 or Q8 develop 408 peak hp and 405 lb-ft of torque. That’s more horsepower than even the Audi S6 TDI. It’s a hefty amount of power and should drastically increase the fun factor in what are essentially three different luxury sedans. ABT hasn’t quoted any 0-60 mph times but, for reference, the stock Audi A6 with its 3.0 TFSI engine can nail 60 mph in a Car and Driver-recorded 4.8 seconds. That’s seriously quick for a stock A6 and that’s already quicker than the Audi S6 TDI.
So with an extra 68 hp and 36 lb-ft of torque, it should be able to get the Audi A6 close to the mid-four-second range, which would be quite remarkable, actually. And it’s all done through an engine tune. So no hardware changes have to be made, there’s no worry of reliability or any issues and it’s relatively inexpensive. It also completely negates the need for an Audi S6 TDI.
Most enthusiasts bemoaned the S6’s switch to diesel power. While it’s not the most thrilling engine, it’s still faster than most A6s. However, it’s also quite a bit more expensive than the standard A6. So for European customers that don’t want the S6 TDI but still want S6-levels of performance, go for an Audi A6 with its 3.0 TFSI engine and get an ABT Sportsline power upgrade. Then get some new coilovers, better brakes and a sweet exhaust and you have car that’s more enjoyable than the S6 and likely cheaper.
This tune is also available on any Audi with that 3.0 TFSI engine. So the aforementioned A7 can also get it, as can the Audi Q8.[Source: ABT Sportsline]
