Citroen Cactus Essential Vehicle Concept with Hybrid Air powertrain 2013

Paris, 5 September 2013 - The origins of CITROËN Cactus date back to the reveal of the C-Cactus concept car at the 2007 Frankfurt show. The Citroen C-Cactus was a radical automotive approach that posed a number of key questions: What do motorists expect from cars in today’s world? And which equipment and features really count? The fascinating exercise pushed engineers and designers to make sweeping changes and set problems differently in order to explore new solutions. The pragmatic approach eschewed the superfluous to concentrate on what makes motorists feel good. The end result, CITROËN Cactus, is a manifest that previews forthcoming models in the C line. More will be revealed in 2014…
CITROËN Cactus is more than a concept car; it is a manifest of the future models in the C line.

The styling of CITROËN Cactus marries the aesthetic to the practical, with designers having sought to find the right volumes and extend efficiency to the smallest details. The idea was to keep only the essential, and optimise that essence to obtain a form of natural perfection. The approach allowed the designers to break free from classic automotive cues and explore ingenious solutions to bring customers real equipment and features.

The body styling of CITROËN Cactus seems original and obvious, both at the same time, lingering easily in the memory like that of all great cars that have marked their time. The styling is easy to identify, with:
> Pure and smooth surfaces in pearlescent white
> Flowing, aggression-free shapes
> Floating quarterlight and roof
> Contrasting design components, each one with a function (protection with Lama grey Airbumps and textured black wheel arches; transport with lacquered black roof arches; cabin light with the large panoramic roof).

One component stands out immediately through its originality: the Airbump.
Located on the sides and the bumpers of the car, the design component expresses a new approach that gives style a function. The Airbump strengthens the styling of CITROËN Cactus, heightening its personality with its originality and personalisation possibilities. The supple skin of the Airbump features a soft treatment that resists scratches and includes air capsules that dampen impact.

CITROËN Cactus has optimal proportions for extra efficiency and driving comfort:

> The dimensions of a compact hatchback (4.21 m long and 1.75 m wide)
> An ideal balance between one-third glazed area and two-thirds wing surface
> High ground clearance (21 cm) but with an optimised height of just 1.53 m
> Reduced overhang, with the wheels set firmly in the corners

The styling of CITROËN Cactus evokes technology and perceived quality and is entirely free of aggression.
The front end, previewing the visual identity of future models in the C line, is characterised by:
> Smooth surfaces showcasing the chevrons
> Flowing forms with a seamless progression from bonnet to wing
> A high-tech light signature with LED daytime running lights and lamps built in to the Airbumps
The styling at the back respects the same principle with 3D-effect LED lights built in to the wide Airbump protecting the boot.

The singular and radical design of CITROËN Cactus also promises a warm, ergonomic and comfortable interior. The absence of side windows, rear window and B pillars beckons onlookers to discover the cabin inside, which has been entirely reworked in terms of architecture as well as in the design of colours and materials

The first objective with CITROËN Cactus was to free up space inside for the driver and passengers, bringing them more ease and user-friendliness and, hence, more comfort.

The slender, floating dashboard fully frees up the floor below and on its upper part offers the front passenger a capacious and easy-access storage space. The dashboard design was made possible by using a 100% digital interface and by optimising the organisation of the driver’s station, in particular by:
> Replacing the instrument cluster with a 7-inch screen
> Switching control buttons for an 8-inch touchscreen connected to all vehicle functions (air
conditioning, audio, satnav, connected services and driver aids)
> Installing the passenger airbag on the ceiling
> Replacing the traditional gearstick with push-button controls on the lower part of the dashboard and steering-wheel paddles

The new architectural approach also informs the front seats, which were designed sofa-style for extra comfort and human warmth.

Extra comfort is also delivered by the panoramic roof, thermally treated to let in the light but not the heat.
It protects passengers from UVs with technology similar to that used for category-4 sunglasses.

The second goal with CITROËN Cactus interior was to provide a stylish and relaxed atmosphere. The interior layout frees up plenty of space and focuses on authentic and natural materials. The seats and doors are upholstered in a combination of two materials evoking contemporary furniture: a blue heathered-cotton fabric and natural “camel” leather (vegetable tanned) also used on the dashboard and steering wheel.

In a nod to the luggage sector, the design of the door handles and the storage space on the upper part of the dashboard was informed by decorative travel-trunk components.

The design choices for CITROËN Cactus were guided not just by interior architecture intelligence but by a whole new approach to the automobile. CITROËN Cactus brings drivers a new motoring experience and total peace of mind, reuniting them with the pleasure and freedom inherent in car travel – a simple, communal, day-to-day pleasure.

CITROËN Cactus technologies are easy to use, economical and environmental in use, accessible to all and connected, and resolutely focused on the new needs of motorists.

The new Hybrid Air drivetrain is a case in point. The full-hybrid technology combines compressed air and the hydraulics of a PureTech petrol engine. This powertrain excellence is written into the Brand’s DNA and has led to breakthrough performance, with fuel consumption of under 3 l/100 km.

Hybrid Air technology has a reduced environmental footprint (no additional battery) and is broadly affordable thanks to:
> Attractive cost in use (45% reduction in fuel consumption in urban driving)
> Easy maintenance and servicing through the combination of proven technologies
> No compromises on interior space

Digital, tactile and connected! All the controls are grouped on the 8-inch touchscreen in the centre of the dashboard, ergonomic, easy to use and offering access to CITROËN Multicity Connect. The driver and passengers benefit from a portal of web-connected applications that takes vehicle data – including mileage, speed, range and GPS position – into account to generate information adapted to motorists’ needs, warning them of risk areas, locating service stations and identifying tourist destinations, among other advantages.

By proposing a fresh new take on design, architecture and technology, CITROËN Cactus stands as a new automotive synthesis. The car’s optimistic approach finally addresses the expectations of people looking to combine practicality with pleasure.

Hybrid Air Technology

Hybrid Air is an innovative combination of tested technologies, with a petrol engine, a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission. An intelligent electronic management system adapts the operating mode to the user’s driving style and optimises energy efficiency. The hydraulic components (motor and pump) recover and store the energy generated by:
- The internal combustion engine operating at top efficiency.
- Braking and deceleration (kinetic energy).

A specific continuous transmission ensures optimal use of the different energy sources depending on the type of driving in three operating modes:
- 1- Petrol power, with the petrol engine as the sole source of propulsion.

-2- Air power, with the hydraulic motor alone transmitting energy to the wheels via the accumulators.

-3- Combined power, with the internal combustion engine and hydraulic motor working together.

Hybrid Air utilises compressed air rather than electricity of conventional hybrid system. Batteries are replaced by a compressed air accumulator while the electric motor generator is an hydraulic motor and pump.
