2012 Ford Focus by Loder1899

German tuner Loder1899 has a neat package for the Ford Focus 2.0 TDCi.
It's always refreshing when a tuner devotes itself to a common man's car and Loder1899 starts things off on the Ford Focus III with a power boost on the 2.0 liter diesel unit that dials output up to 195 PS (143 kW / 192 bhp) and 395 Nm (291 lb-ft) of torque from the series' 140 PS (103 kW / 138 bhp) and 320 Nm (236 lb-ft).
Loder1899 also lowers the Focus by 35 mm, adds stainless-steel dual exhaust pipes and offers a full body kit (in carbon-fiber as optional) in an RS-design. The complete package also includes LED daytimers and carbon covers for the headlights.
Wheels on offer include 18-, 19- and 20-inch alloy rims in various designs.
Loder1899 offers the entirety of the package a-la-carte with prices starting at €27,695 (power boost only), including the car.
Ford Focus RS by MR Car Design

German tuner MR Car Design has turned the Ford Focus RS into an Audi RS3 and 1-Series M competitor.
The Erfstadt-based tuner ups the power quotient on the Focus RS from 305 PS (225 kW / 301 bhp) to 360 PS (265 kW / 355 bhp) by means of an ECU remap, in-house exhaust and downpipe, 200-cell catalytic converter and a sport air filter from K&N.
A little weight also gets dropped from the Focus RS, and all that tuning work is good for a substantial reduction of the series model's 0 to 100 km/h (62 mph) sprint time of 5.9 seconds. Without providing any specifics, MR Car Design says their version handily beats the original.
The Focus RS also gets a Variant 1 KW coilover suspension to better manage those lateral forces on the road.
Ford Focus RS Black Racing Edition by Anderson Germany

Tuner Anderson Germany has something for those waiting anxiously for the next-generation Focus RS - the Ford Focus RS Black Racing Edition.
The Düsseldorf-based tuner takes a unit from the last generation Focus RS series and turns it into a very special looking car. It comes in a matte black exterior finish with contrasting red touches.
Of course, Anderson offers performance tuning on the RS, too, dialing output up to 420 PS (309 kW / 414 bhp) from the series 305 PS (224 kW / 301 bhp) on the turbocharged 2.5 liter 5-cylinder unit.
On the inside, as can be seen with the pics here, there's a black leather and Alcantara finish with red stitching. This replicates the color contrast seen on the vehicle's exterior.
