My previous review and some consideration of the Audi S5 after I sold my 335i....
7-speed S-tronic
dual-clutch transmission, All-wheel drive
Quattro, Torsen
limited slip centre differential, better interior and
B&O Sound System, practical 4-door car with coupe-looking sportsback..
Now for some future potential upgrades...
Sportec Tunes Euro-Spec Audi S5 3.0T To 425-HP
Sportec’s tuning package offering consists of an air filter (that is oh-so-free-flowing) and an ECU remap. Naturally the forced inducted motor gets quite the boost from a retune and peak power jumps from 328-hp to 425-hp, close to a 100-hp gain. The torque increase isn’t as substantial, but still very respectable going from 325 ft-lbs to 379 ft-lbs. We’re guessing this simple pair of modifications makes our S4 (and their S5) an absolute blast to drive.
Labelled the ‘Stage One’ upgrade, Sportec’s S5 performance enhancement package consists of a free flowing air filter element and a carefully developed ECU remap. In combination this has a dramatic effect on the power characteristics of the supercharged 2995cc Audi engine, with peak power increasing from 328 bhp at 6000 rpm to 425 bhp at 6640 rpm, a significant gain of 97 bhp.
Similarly, Sportec’s Stage One upgrade delivers a prodigious increase in torque output on the Audi S5, producing a maximum of 520 Nm (379 lb.ft) at 4250 rpm, compared to peak figure of 440 Nm (325 lb.ft) from the factory.
Careful development by Sportec’s technicians ensures that over 80% of the maximum torque output is available from 2750 to 6250 rpm, which both perfectly suits the characteristics of the car’s 7-speed S-Tronic transmission and highlights the user-friendliness of the conversion.
The additional power and torque output realised by the Sportec Stage One upgraded Audi S5 considerably enhances the in-gear and fast cruising performance of the car, in keeping with its luxury GT credentials. However, when exercised to the full, it reduces the 0-62 mph (100 kmh) by 0.5 seconds to 4.6 seconds, while top speed is limited at 155 mph for safety reasons.
