Instrumented Test

Far more power for your insanely strong auto.
From the February 2015 concern of Vehicle and DriverTuner vehicles, those science projects engineered to make currently-quickly automobiles really berserk, are frequently a lot more problems than they’re worth. But what if you could make a 2-ton-plus sports sedan run a sub-11 quarter-mile with absolutely nothing a lot more than a computer upgrade? Wouldn’t that be worthwhile?
That’s the pitch of Opelika, Alabama–based APR with its Stage 1 Audi RS7. Not that the Audi needs much assist from this longtime Volkswagen tuner. The stock RS7, with its 8-speed automatic and Quattro technique, reaches 60 mph in 3.4 seconds and blitzes the quarter-mile in 11.6 seconds at 123 mph.

Nevertheless, fitted to the RS7 noticed right here ($ 129,374 as tested), APR’s Stage 1 tune boosts the output of the stock twin-turbo 4.-liter V-8 from 560 horsepower and 516 pound-feet of torque to a claimed 674 and 700, respectively, on 93-octane pump gas. If that nevertheless appears soft, a second tuning map accessible at the touch of the cruise-manage stalk yields 728 ponies and 744 pound-feet on 100-octane racing fuel for a correct Hellcat-crushing act. All that’s needed is a computer software reflash for the engine personal computer ($ 2999 installed) that can be performed at any of APR’s 400-plus companion Audi dealers.
Although our testing wasn’t without having issues—an APR engineer had to exorcise a demon from our car’s brain just before it ran properly—the further thrust had the 4508-pound Audi pulling violently with the Thor hammer down. It briefly spun all 4 tires during launch, and our test gear reported an impressive 2.9-second warp to 60 mph on premium unleaded, with the quarter-mile blurring past in 11. flat at 129 mph. Not fairly the high-10-second hero times APR promised, but still wickedly swift for just a handful of further lines of code.

The new programming also sharpens throttle response and ups the RS7’s electronically restricted leading speed from the stock 190 mph to a claimed 202. There are no changes in the cabin to indicate the added power underhood, with handle for the a variety of applications spliced into the Audi’s cruise-handle stalk. Extra management is offered through the APR Mobile method ($ 200), which makes use of a Bluetooth dongle plugged into the car’s OBD II port to relay information to a smartphone app.
Costing the exact same as the RS7’s optional Alcantara headliner, APR’s Stage 1 setup is a tantalizing functionality worth. Just don’;t forget that, as with all aftermarket engine mods, the car’s factory warranty will be shredded and your results might differ. APR’s 560-hp plan for the lesser Audi S6 and S7 ($ 1499) could be much more attractive nonetheless, but that would be way as well sensible.
