Newcomers to Alfa Romeo's MiTo -- in Europe initially -- will have access to greater environmental correctness with the introduction of latest-generation MultiJet engine technology.
The little three-door sports hatch is now available with the 1.3-litre MultiJet II engine -- a development of the piezo-based system introduced on the Alfa 156 JTD in 1997.
As well as ensuring compliance with Euro 5 emissions standards, the new turbodiesel maintains performance while improving fuel economy and exhaust emissions. In 70kW form, the new engine returns an average 4.3L/100km and emits 112g/km of CO2. The previous 70kW MultiJet quoted 4.5L/100km and 119g/km.
Claimed acceleration figures are the same as the previous 70kW MultiJet (0-100km/h in 11.6 seconds), but Alfa says the new engine is able to punch out as much as 25 per cent more low-rpm torque than before, improving responsiveness and flexibility.
The second generation MultiJet engine is made more efficient by a new solenoid servo valve controlling the injection sequence to as much as eight injections per cycle (five previously) and a second generation variable vane turbocharger that contributes heavily to the greater low-rpm torque output.
Other contributors to the Mito MultiJet II's green credentials include the standard-fit Start&Stop function, and a diesel particulate filter.
It also uses the MultiAir variable-lift inlet valve system that optimises airflow into the combustion chambers.
Spokesman for Alfa Romeo in Australia, Edward Rowe, said the MultiJet II MiTo will come to Australia, but "not in the lowest-power form," indicating only the 99kW version will make its way here.
The new diesel will also coincide with introduction of the TCT twin-clutch transmission Alfa has been hanging out for in Australia. Coupled to the TCT gearbox, the 99kW MultiJet accelerates the MiTo to 100km/h in a rapid 8.4 seconds. Claimed CO2 emissions figure is 129g/km.
The MultiJet engine and TCT transmission will arrive in local MiTos around May/June this year, moved forward from earlier advice it wouldn't arrive before the third quarter.
Also on the agenda for MiTo is the range-topping Quadrifoglio version using the 127kW turbo petrol engine. For the moment, Australian MiTos are available only with 88kW and 114kW turbo petrol engines.
