An engine of generous output
This 2.0 16v turbocharged engine (F4Rt) develops
power of 165kW (225bhp) at 5,500rpm and maximum
torque of 300Nm (30.6 mkg) at 3,000rpm. To provide
great flexibility of operation, 90% of this maximum
torque is available between 2,000 and 6,000rpm..
The increases in power and torque were the result of
several changes and optimizations carried out on the
pistons, the crankshaft and the twin scroll type turbocharger. This latter benefits from a special turbine
and compressor to improve cylinder filling and reduce
response time. The fuel injectors are matched to the
greater airflow provided by the turbo. The engine is
equipped with a specially developed management
computer to optimize ease of operation.
A low-inertia twin-mass damping flywheel minimizes
excitation of the gearbox by the crankshaft.
This feature therefore improves acoustic performance
without penalizing pick-up response. The socalled
wide face cylinder block results in stiffer
coupling with the gearbox to the further benefit of
acoustic performance.
