S4 AVANT

Tuner firm, Sportec has added an extra 92hp to this ride. However, its 0-62mph is only 0.1 seconds quicker. But, other areas of performance have improved much more. In-gear acceleration, rolling acceleration and everyday driving will all be improved by the extra power. So, race this in a rolling start.

You can outfit this Audi with a customizable body kit and 19- or 20-inch rims. Other options include lowering it 30mm, adding stiffer springs and upgrading the brakes, too. Also, you can pick and choose what you want from Sportec, opting for a giant package with everything or just add a body kit and lower it some and save some cash.

Sportec hasn't officially announced the prices for everything or when they plan to sell these mods just yet.

MTM is probably most known for strapping two engines to an Audi TT in order to set a speed record. Thus, MTM is definitely an "all-out" tuner that I have come to respect due to their innovative/insane projects.

The new Audi S4 AVANT is the most powerful Audi S car out right now. The V6 3.0L supercharged engine will be boosted from 333hp (248kW) to 430hp (320kW) and 380lb-ft (515Nm) of torque. With the new engine upgrades this Audi will run from 0-100km/h (62moph) in just 4.7 seconds!

MTM also offers a custom exhaust kit, bimoto wheels (19- and 21-inch), MTM height adjustable suspension and performance brakes with 380mm discs and 8-piston calipers. Currently, MTM has not announced the specifics of the engine upgrades or any prices on these modifications. We might learn more at the Frankfurt Auto Show in September, though.
