On the International showroom in Geneva Volkswagen company presented conceptual SUV with a hybrid power-plant – Cross Coupe TDI-Plug-In-Hybrid Concept. This car – one more step forward on road of development of new technologies. In December, 2011 such conductor already became VW Cross Coupe Plug-In-Hybrid which was resulted by two electric motors and one gasoline engine with turbo-supercharging TSI. Thanks to an innovative feed circuit the crossover consumed only 2,7 liters on 100 km of run.
However Volkswagen continued probes and managed to promote on one step forward. Even more economic car Cross Coupe with the turbo diesel engine with system of direct injection (TDI) and two electro motor, having sensationally low average fuel consumption has been as a result created: 1,8 l/100 of the km, defined on a new European drive cycle (NEFZ). Such expense corresponds to level of blowout CO2 only 46/km.
The conceptual novelty presented on the Geneva showroom weighs 1885 kg, its hybrid power-plant develops total capacity in 306 h.p. that allows the car to be dispersed on road to 220 km/h.
Technically VW Cross Coupe TDI Concept is based on a new modular platform with a cross-section arrangement of the power unit (MQB). Within the limits of platform MQB certain design data which are unified are developed. In new Cross Coupe, created on platform MQB, elements SUV of the future generation are merged together: engine TDI, 7-step КП DSG, lithium-ion the battery in the central tunnel, the electric motor of a drive gear of front wheels capacity of 40 kw, and the electric motor of a drive gear of rear wheels capacity of 85 kw, electric transmission.
However, thanks to modular system concept can be executed not only with drive gear Plug-In-Hybrid (the traction accumulator battery with a socket for gymnastics from an external source) but also as a full hybrid (without the interface for connection of an external source for battery gymnastics), and also it is simple with an internal combustion engine or the electric drive.
Presented to Geneva Cross Coupe it is accelerated with 0 to 100 km/h of all for 6,5 with. Engine TDI develops the maximum twisting moment of 400 Nanometers already in a range to 1600 rpm. By pressing both buttons of the traction electric motor add to them of 180 more Nanometers (front) and 270 Nanometers (rear). At sharp speedup when all engines work on a total power mode, in drive gear system the total twisting moment of 700 Nanometers is realized. With such indicator concept it is capable to intrude in sphere of sport cars; thus it spends fuel less, than a standard city midget car.
In a movement mode on an electric drive gear at speed limited in this case to 120 km/h concept it is capable to overcome distance to 45 km. At movement it is exclusive on electric pull-rod a drive gear it is carried out only on rear wheels. The driver can independently make the decision, whether move on the greatest possible distance on an electric drive gear (while the accumulator battery charge suffices) or not. For this purpose to it simply enough to press a key of a choice of a mode of the drive gear, close to a selector lever. As soon as degree of gymnastics of the accumulator battery or other parameter demands turbo diesel connection, it again for fractions of a second and without any appreciable jerks is connected to transmission.
