The MTM Audi S4 Avant represents the latest tuning proposal for the already sporty Audi S4 3.0 V6 quattro, featuring a set of discrete exterior modifications as well as a performance upgrade.
On the outside you can notice the red painted front lip and the side graphics right above the side sills, as well as the new multispoke design light alloy wheels that the MTM Audi S4 Avant is sitting on.
As far as performance the MTM Audi S4 Avant has been fitted with a turbocharger so the 3.0-litre V6 engine can now output 430 hp (317 kW) and 515 Nm of torque at 4,760 rpm. Power is sent to all four wheels through a 6-speed manual gearbox and accelerating from 0 to 100 Km/h takes only 4.7 seconds.  
The MTM Audi S4 Avant has also received a new exhaust system with two oval black tailpipes featuring throttle valves, a new suspension adjustable in height and 380×34 mm front brakes with 8 piston calipers that should safely harness the extra power.
