German tuner offers performance boosting as well as an aerodynamic kit, 18 or 19-inch wheels, and interior upgrades.

Mercedes-Benz tuner A.R.T. has some improvements in mind for the facelifted 2011 Viano passenger van.

The German tuner has announced a new kit for the Mercedes-Benz Viano that includes performance boosting for its various engines.

For the Viano CDI 3.0 liter V6 diesel, that means a bump up to around 268 PS (197 kW) and 530 Nm of torque. On the 3.5 liter petrol V6, A.R.T. takes output up to 327 PS (240 kW) at 405 Nm.

To go with the extra zip under the hood provided to the Viano, A.R.T. also supplies a body kit, suspension tuning and new wheels.

The aerodynamic kits consists of a front skirt with LED daytime running lights, contoured side sills, a rear skirt and a rear roof spoiler.

The tuner also offers chassis-lowering and a new exhaust silencer system with 80 mm stainless-steel quad-pipes branded with the A.R.T. logo.

For a new set of 18 or 19-inch wheels, A.R.T. offers the monoART1 or monoART2 light-alloy rims wrapped in either 245/45R18 or 255/40R19 tires, respectively.

On the inside is an ergonomically-shaped sport steering wheel and a leather finish with wood and carbon fiber trim in various combinations. A.R.T. also offers a multimedia DVD system with multiple display screens, a play station and other business equipment.
