VW Golf R Black Pearl with 530HP

German tuning firm Siemoneit Racing felt like it could use some extra ponies.

Siemoneit Racing calls its tuned VW Golf R the ‘Black Pearl’for obvious reasons- and it offers customers a choice of two performance packages. The first boosts the 2.0-liter turbocharged four-cylinder engine’s output from 270HP and 320Nm to 355-horses and 485Nm (357.7 lb-ft) through thanks to the updated ECU software, custom exhaust and a new air intake system.

The second and more comprehensive package transforms the Golf R into a 530-horsepower monster by further tweaking the engine software, and adding a larger turbocharger, a new intercooler and a different exhaust system.Other available options include a lightweight hood made out of carbon fiber.

VW GTI Reifnitz with 370HP

This is the VW Golf GTI Reifnitz from Volkswagen Coaching GmbH, a training division of VW, which the German automaker has debuted at the GTI-Wörthersee event in Austria.

With this model, the celebration of 35 years of the Golf GTI continues, although this model is for show only.

This Mk6 GTI variant comes with an aero kit and a new paint design along with a serious engine upgrade.

Output on this GTI Reifnitz totals 370 PS (272 kW / 365 bhp) and 480 Nm (354 lb-ft) of torque, achieved by means of an APR Stage III turbocharger system along with an APR RSC performance exhaust which helped up-tune the 2.0 liter TFSI unit to almost double its standard power rating.

But even if you can't buy this GTI Reifnitz, Alabama-based tuner APR will be happy to sell you the turbocharger and exhaust systems that went into it.
