Audi TT RS by O.CT

Austrian tuner Oberscheider Tuning (O.CT) has a performance package for the Audi TT RS that can squeeze even more power from its 2.5 liter, 5-cylinder TFSI engine.

The conversion kit for the power upgrade includes new hardware components (such as the charge air cooler kit) along with an ECU remap that dials output up to 420 PS (309 kW / 414 bhp) and 570 Nm (420 lb-ft) of torque from the series' 340 PS (250 kW / 335 bhp) and 450 Nm (332 lb-ft). Also helping boost the power rating is a stainless-steel exhaust system with silencer and an additional valve-controlled rear silencer.

O.CT also adds a set of 9 x 20-inch (ET35) alloy wheels in a twin-spoke design which weight just shy of 14 kg each.

The tuner provides a KW V3 coilover suspension kit to help handle the extra go on the road.

Porsche Cayenne by Hamann

German tuner Hamann will debut the Hamann Guardian at the Geneva auto show based on the Porsche Cayenne Turbo.

The extensive tuning job begins with a design-changing aerodynamic kit. That includes a front apron with large air inlets and integrated LED daytimers and fog lights, a lighweight carbon bonnet with a power dome slit for engine ventilation, and fender extensions and side skirts that widened the Cayenne by a 120 mm at the front axle and 160 mm at the back. At the rear is also a rear apron with integrated diffuser holding two massive centrally-mounted stainless-steel exhaust pipes - gaping at 120 mm in width each.

Power is boosted by means of a sport exhaust system, silencer, catalysts and air filter. All that hardware coupled with an ECU remap increases output on the 4.8 liter V8 twin-turbo unit to 550 PS (405 kW / 544 bhp) at 6,100 rpm with a torque rating of 770 Nm (568 lb-ft) between 2,300 and 4,600 rpm (series - 500 PS / 368 kW / 493 bhp). That makes for a 0 to 100 km/h (62 mph) sprint time of 4.6 seconds for the Cayenne and a top speed of 300 km/h (186 mph).

Hamann furbishes the Cayenne with a ceramic sport brake system too and fits it with ultra-light forged rims, 11J x 23-inch, wrapped in Dunlop Sport Maxx tires sized 315/25R23.

Also for the ride is a sport suspension module for the Cayenne's air suspension that lowers the Hamann Guardian by 35 mm over the series model.

For the interior finish, Hamann fits a full leather upholstery with stitched embroideries for the dash and seats. An ergonomically refined steering wheel with airbag is also part of the cabin tuning with carbon trims added to the instrument panel and center console.

Mercedes-Benz SLS AMG by Mansory Cormeum

This is the Mansory Cormeum based on the Mercedes-Benz SLS AMG.

Designed and named by the tuner's owner and head designer Kourosh Mansory, the SLS gets wrapped in a complete carbon shell for a 90 kg weight-saving diet and a substantially revised look.

The body kit includes a new lightweight roof and wing doors, front skirt with large air inlets, widening fenders that extend the SLS by 66 mm at the front axle and 84 mm at the rear axle, as well as side skirts that make the sport coupe appear lower. At the back is a rear spoiler with carbon flaps and a race diffuser for additional downforce.

Engine tuning consists of increasing output to 660 PS (485 kW / 651 bhp) while a performance upgrade to 800 PS (588 kW / 789 bhp) is also in the works.

For the wheels are 9 x 20 inch rims at the front with 265/30R20 Michelin tires and 11 x 21 inchers at the back wrapped in 295/25R20 Michelins.

New springs and dampers lower the SLS AMG by 20 mm too.

On the inside Mansory does its luxuriating thing with a hand fitted soft leather finish with decorative stitching, carbon trim, of course, a newly designed center console and other touches such as the aluminum pedals and sport steering wheel with a full-sized airbag.

The name, Cormeum, comes from an operatic aria called Vide Cor meum composed by Patrick Cassidy and based on a sonnet in Dante's "La Vita Nuova".
