Volkswagen's Cross Coupe concept goes diesel-electric for Geneva. Could a market debut be on the horizon?
Most production hybrids are built around the pairing of an electric motor with a petrol engine. You'll sometimes find more than one motor, and occasionally the engine will be a big ol' V8, but the petrol factor is almost always a constant.
So, what of diesel?
Peugeot Citroen's Hybrid4 system and the recently-revealed Mercedes-Benz E 300 Bluetec are the standout examples in the small diesel-electric hybrid arena, with the former already on the international market and the latter coming soon.
Volkswagen has also tinkered with the concept, with the XL1 Super Efficient Vehicle pairing a small 800cc two-cylinder turbodiesel with a 20kW electric motor.
Combined with the benefit of the concept's 795kg kerb weight, Volkswagen says the hybrid pairing will return fuel consumption figures of just 0.9 l/100km.
You'll remember the car from its Tokyo Motor Show debut last year, but back then it was driven by a more traditional petrol-electric hybrid system.
This time, the Cross Coupe gets a new splash of paint, and a vastly improved fuel economy.
Where the earlier concept paired its two electric motors with a 85kW petrol engine for a fuel consumption rating of 2.7 l/100km, this new one will pair a small diesel (specs haven't been released) to return a 1.8 l/100km rating.
Is Volkswagen building toward the debut of a sportier new SUV, or a new (and slightly longer) Tiguan?
While a replacement for the Tiguan will be on the horizon, it remains to be seen if the Cross Coupe - which is built on Volkswagen's new MQB family platform - offers any hints of its styling. Only time will tell.
