Auto Car | Citroen C-Metisse Concept in 2006 | C-Métisse proves that elegant design lines of C-Métisse that high-performance car can also be green, combining a top speed of 155mph with the ability to cover about 45 miles per gallon on cycle.Hal also boasts real driving sensations with a driving position featuring the technology latest, high-performance drivetrain and a specially designed diesel-Métisse hibrida.C not just a car to stir the soul penonton.Kejutan first is a back door on the vehicle is high-tech equipment perfectly matches the design of the driving position whose original central console is divided by five extension.
With its diesel hybrid technology, C-Métisse respects the environment. This is particularly true in the city in ZEV (Zero Emission Vehicle) mode – an “extended’”, completely silent all-electric mode with a range of around 3 km at 30 kph – as well as on roads demanding successive acceleration and deceleration. In this second case, the hybrid architecture makes it possible to limit consumption by using the two forms of energy together.On motorways, the V6 HDi diesel combustion engine with a DPFS (particulate filter) sets high standards of efficiency, based on its intrinsic qualities.By controlling fuel consumption and thus pollutant emissions, C- Métisse boasts combined cycle consumption levels of 6.5 l/100 km for CO² emissions of 174 g/km.
No sacrifices have been made in terms of driving pleasure, which remains a key priority for motorists. If the driver makes prolonged use of the accelerator pedal, the boost function kicks in to provide the immediate torque required. This function combines the torque of the combustion engine with that of the electric motors to endow C-Métisse with a level of performance worthy of a high-spec sports vehicle, without pushing up fuel consumption. C Métisse accelerates from 0 to 100 kph in 6.2 seconds and takes 25.4 seconds to cover 1,000 m from a standing start.Rather than pursuing the quest for ever higher speeds that are not practicable in normal traffic conditions, the emphasis has been placed on driving pleasure with clean, fast acceleration. For example, C-Métisse accelerates from 80 to 120 kph in 4.2 seconds.Also, the vehicle remains in 4-wheel drive mode while the boost function is active, since the electric motors drive the rear wheels while the combustion engine drives the front wheels. Thus ensuring impeccable traction.Also, when the ESP sensors report low grip conditions, C-Métisse can activate its electric motors and thus adopt a 4-wheel drive configuration. The electric motors deliver improved traction and ensure full use of the potential of C-Métisse in all conditions and in complete safety.
Alongside the engine and motors, the drivetrain comprises a pack of high-voltage batteries supplying the electric motors. Positioned in the centre of the vehicle, the pack is recharged by the electric motors during deceleration phases, thus converting the vehicle’s kinetic energy into electric energy.
The drivetrain and braking control unit – the nerve centre of the system – automatically manages the energy configuration: transition from 2- to 4-wheel drive, energy recovery and recharging of batteries.Aerodynamics optimised to combine high standards of performance with respect for the environment.Special emphasis was placed on the aerodynamics and flowing design of C-Métisse, these being key Citroën values. The objective was to enhance the vehicle’s dynamics, road manners and performance while showing respect for the environment.Far from being a gratuitous styling exercise, the forms of C-Métisse combine visual appeal with dynamic efficiency. C-Métisse boasts a Cd of 0.30 obtained by its taut, flowing lines, as well as by a series of innovative features such as the enlarged air intakes at the front, the flat underside of the car, the two retractable rear airfoils and the rear fixed-fin spoiler. All these features play an active role in reducing aerodynamic drag and lift, thus pushing the car to the ground and improving roadholding.
Limited weight for performance and fuel economy.Particular efforts were made to reduce vehicle weight in order to achieve both performance and fuel economy.With its carbon body and carbon trellis supporting the powertrain and front axle, C-Métisse weighs just 1,400 kg, batteries included. A remarkable figure for a vehicle of this size.The architecture of the diesel hybrid powertrain also contributes to this result. The positioning of the electric motors in the rear wheels and the position of the battery pack in the centre of the vehicle distributes the weight perfectly between front and rear, for improved road behaviour.A car of astonishing style and equally astonishing performance with its diesel hybrid powerplant, C-Métisse combines the concept of ecology with automotive emotions and sensations. Through its ability to challenge received ideas, it illustrates an objective long pursued by Citroën: to develop vehicles that reflect the spirit of the times, without losing sight of the essential – driving pleasure.
