Modern, Low-Consumption, Clean
Engine
The new Mazda2's engine is both cleaner and uses less fuel than
before, while the new lighter car promises to be quicker than
before.
All models are powered by a Mazda developed MZR petrol engine: a
1.5-litre unit that produces 76kW (EEC). The engine has sequential
valve timing (S-VT), optimised exhaust-valve timing and a variable
induction system (VIS) that enhances torque across the entire rev
range.
High-tech Mazda Engine
The 1.5-litre MZR series engine operates with sequential valve
timing (S-VT) which provides variable valve timing for the intake
valves and optimised timing of the exhaust valves. In addition to
this, the 1.5-litre adds a variable induction system (VIS) that
boosts torque across the entire rev range.
The intake manifold is made of plastic and 'breathes' through
600mm long intake runners, making robust torque available at low
engine speeds. The intake manifold also has integrated tumble swirl
control valves (TSCVs) that ensure high combustion stability, even
during slow driving, and together with the exhaust-gas
recirculation, improve fuel consumption and emissions.
The new Mazda2's engine has an electronically controlled
throttle that translates pedal input quickly and precisely. It has
a displacement of 1,498cc and produces a maximum of 137Nm of torque
at 4,000rpm (EEC).
In manual form the new Mazda2 is expected to accelerate from
0-100kmh in about 10 seconds and has a theoretical top speed of
about 190km/h.
Mazda engineers worked hard to reduce internal frictional loss.
The measures undertaken include changes to the piston rings and
lands, fine-tuning the piston skirts, optimising the piston pin
offsets and redesigning the oil passages.
Fuel consumption is improved with the new Mazda2 using an
average of just 6.4L/100km on the ADR 81/01 cycle compared with
6.6L/100km on the present model, while automatic transmission
versions now average 6.8L/100km compared with 7.0L/100km for the
superseded model.
Mazda2 offers an easy shifting, precise five-speed manual or a
four-speed automatic transmission. The manual gearbox has
double-cone synchronization on first and second gears ensuring easy
slow gear shifting and shifting during cold weather.
