Volkswagen XL1 TwinDrive Technology

The Volkswagen XL1 undoubtedly makes a very strong case for itself by returning an astonishing 100 kmpl mileage figure. While the 795kg light weight does contribute to its efficiency, the real economical wonder is the vehicle’s powertrain. Representing the internal combustion engine is a twin cylinder 0.9 litre diesel engine that generates 48PS of power, while the electric motor is made up of a 5.5 kilowatt motor that develops 27PS of power. 

The battery of the VW XL1 is a 220V lithium ion unit that has a capacity of 5.5 kilowatt hours, 60 cells, is cooled by water and has a carbon fibre reinforced polymer casing that has pegged its weight at 68kg. Volkswagen states that the battery has been designed to last the lifetime of the vehicle. 

Both forms of power are synchronised to power the car by Volkswagen’s TwinDrive technology. The TwinDrive technology is essentially a plug-in hybrid drivetrain that allows the XL1 to be driven purely by electricity, fuel and both power sources combined. 

While the 100kmpl figure is quite an economical one, the Volkswagen XL1 is also capable of travelling a distance of 50km on electricity alone when its battery pack is fully charged. The battery is charged on the go by brake energy recuperation (converting kinetic energy during braking into electricity) and can also be charged by plugging it into an external electric power source. 

When the battery runs out, the internal combustion engine can power the car identically the way a conventional engine powers a vehicle. 

The Volkswagen XL1 can also be powered by the internal combustion engine and the electric motor at the same time to provide an economical journey where the electric motor provides energy during partial acceleration taking some of the load off the engine. However, both powertrains combined produce a total of 75PS of power allowing the XL1 plug-in hybrid car to go from 0-100km/h in an impressive 11.9 seconds and onwards to an equally commendable top speed of 160 km/h.

All in all, the Volkswagen XL1 looks like a very promising electric vehicle that has the potential of rewriting the capabilities and practicality of hybrid vehicles.
