Volkswagen Cross Coupe – Diesel Electric Hybrid

Cross Coupé: diesel-electric hybrid makes Chinese debut

Also making its Chinese debut is the Cross Coupé concept.  This diesel-electric hybrid was first shown at the Geneva Motor Show and promises a combined cycle figure of 1.8 litres per 100 km (around 157 mpg) and emissions of just 46 g/km of CO2.  This is possible thanks to a drivetrain consisting of a turbodiesel direct injection engine and two electric motors, which together produce 306 PS (225 kW) of power.  That’s enough to propel the 1,858 kg Cross Coupé to a top speed of 220 kmh (137 mph).

The Cross Coupé is built on Volkswagen’s new modular transverse matrix (MQB).  This revolutionary platform standardises certain parameters across models (such as the distance between the accelerator pedal and the front axle), but makes many other parameters variable, creating huge flexibility for developing a wide range of models.  This means it is as easy to make a Cross Coupé that uses a petrol-electric hybrid system as a diesel-electric hybrid, or to use combustion engines alone, or electric power alone for example.

The Cross Coupé uses many elements of the new MQB modular toolkit: MQB front and rear SUV suspension, plus the new 190 PS TDI EA 288 engine, in this case mated to a six-speed DSG transmission.  Added to this is a 9.8 kWh lithium-ion battery in the centre console, plus a 40 kW electric motor at the front and an 85 kW motor at the rear.  Together, these can propel the Cross Coupé from zero to 62 mph in 6.5 seconds.

The 2.0-litre TDI engine alone provides the Cross Coupé with 295 lbs ft of torque (400 Nm) from just 1,600 rpm, while the front E-motor provides 133 lbs ft (180 Nm) and the rear E-motor a further 199 lbs ft (270 Nm)  The drive system can provide a maximum of 516 lbs ft (700 Nm) at any one time.  This helps give the Cross Coupé the performance of a sports car, but with efficiency greater than that of a city car.

In pure electric mode, the Cross Coupé can cover up to 45 km (28 miles) at speeds of up to 120 kmh (75 mph).  If the TDI is needed (for example if the battery’s charge is depleted), it seamlessly re-engages within fractions of a second.  So that in theory, the Cross Coupé’s 55-litre fuel tank gives it a range of 1,287 km (800 miles).

The Cross Coupé is a concept vehicle, and there are no plans to put it into production.
