The most interesting features of Citroen’s booth at the Geneva Show 2012 include DS3 Racing S. Loeb limited edition, and the new DS4 Racing concept.

The rest of the lineup are good too. It includes restyled C1 & Berlingo Multispace, production version of the C3 Red Block, DS4 & DS5 Paris Rendez-Vous limited editions, and the Citroen DS3 Ultra Prestige.

The Ultra Prestige is a version of the DS3 for those who like a more sophisticated approach to luxury. Powered by a THP 155 petrol engine or a fuel and CO₂ efficient e-HDi 110 diesel with Stop & Start, the car is on sale in UK now with prices start from £20,700.

The DS3 Loeb edition is limited to just 200 examples based on DS3 Racing. designed to honor the most successful rally driver of all time, this version of the car comes in a unique matt black colour with a textured effect, an industry-first. The roof, door mirrors, grille, dashboard fascia and gearstick base all feature a contrasting shade of red. The new model also features special decals and, as an exclusive limited series, sports a numbered identification plate on the roof lining.

The DS4 Racing is also one of the must-see cars at this year’s Geneva Motor Show. The production-intent concept features new carbon fibre components including an air diffuser, front splitter and wheel arch extensions. The 1.6-litre turbo petrol engine, developed by Citroën Racing, provides up to 256bhp (160bhp per litre), which is a record for a Citroën series production car. This spectacular performance is accompanied by CO₂ emissions of just 155g/km.

As for the other notable cars on display, you have the C3 Red Block that comes with more dynamic suspension settings – roughly 50% more stiffness and nearly 25% less roll – with the steering adapted to the new suspension settings for a more defined road feel. The body height has been lowered 25mm and ESP has been fitted as standard for even more verve and control. C3 Red Block is available with three engines, VTi 120 petrol, e-HDi 90 diesel and e-HDi 100 diesel, mated to manual gearboxes.

The new C1, the Aircross C4, and a hybrid version of the DS5 are also present at the show.
