It is the goal of the Group to offer attractive, safe and environmentally
friendly vehicles which are competitive on an
increasingly tough market and which set world standards in
their respective classes. For example, volkswagen offers the
Passat TsI EcoFuel and the new generation of the Touran TsI
EcoFuel , which combines for the first time natural gas power
and turbocharged direct injection. The Caddy features as Eco
Fuel the possibility of the natural-gas engine for all variety of
different models.
Under the brand name sunGas ® , volkswagen is involved in
the production of largely Co -neutral biogas. natural gas and

volkswagen expanded its successful natural gas fleet with the
TsI EcoFuel models. The Passat TsI EcoFuel and the Touran TsI
44 B I o G a s P a r T n E r – a j o I n T I n I T I a T I v E
EcoFuel may be ordered with the 6-speed manual gearbox or
with the innovative dual clutch gearbox DsG. This Passat, in
combination with the DsG gear box, is currently the only model
in the midrange class that achieves a Co emissions value of
2
119 g/km.
The combination of the natural gas drive system and the turbocharged
direct-injection in the Passat TsI EcoFuel is unique in
the world. This advantageously combines fuel efficiency with
dynamics. a modest rate of fuel consumption, as little as 4.4 kg
natural gas per 100 km (with DsG), and a 31-litre petrol tank
result in a maximum driving range of over 900 kilometres.
The 1.4-litre engine generates 110 kW (150 Ps). With both gearbox
versions, a powerful 220 newton metres of torque are available
between 1,500 and 4,500 rpm. The dynamic performance
achieved was previously unknown for natural-gas vehicles: the
car accelerates from 0 to 100 km/h in just 9.8 seconds. This fuel
economy and dynamic natural gas engine is now available with
an optional DsG gearbox in the Touran TsI EcoFuel.
The engine has specially been developed and optimised for the
permanent use of natural gas: valves, pistons and the engine
management system have been designed for the changed
requirements of natural gas operation. In conjunction with
reduced fuel tax it offers considerable advantages in running
costs in comparison to petrol engines.
In addition to the Caddy EcoFuel the offer includes since 2009
the Caddy Maxi EcoFuel with a sensational range of 700 km.
