The Alfa Romeo MiTo is now available in the UK with the new Euro 5-ready 1.4-litre MultiAir turbocharged engine which, in Cloverleaf spec, combines 170bhp, a 0-62mph time of 7.5 seconds, a combined fuel consumption of 47.1 mpg and emissions of 139g/km CO2.
The engine also comes in a 135bhp version in Lusso and Veloce spec. Standard across the range is Alfa’s Start&Stop system.
MultiAir meters the direct air charge at the cylinder inlet ports with an advanced electro-hydraulic actuation and control system, and the ability to optimally adjust valve timing and lift to exactly suit different engine speeds and loads, the idea being to ensure strong low- and mid-range torque and top-end power, combined with good economy and low emissions.
The 1.4 TB MultiAir 135bhp engine, when compared to the 1.4 TB 120bhp unit, has CO2 reduced by over 10%, fuel consumption reduced by up to 10%, maximum power increased by 12.5%, acceleration (0-62mph) reduced by up 0.4 seconds, better throttle response and less turbo lag.
The MiTo’s new range of MultiAir engines are based on the Fiat Group’s established 1.4-litre ‘FIRE’ block. The MultiAir top-end is modular and designed to be fitted to existing engines. From launch, the engine has been available with three power outputs, starting with the 105bhp non-turbo unit. For the UK market, however, the choice for Alfa Romeo customers is between the two turbocharged versions.
The 135bhp version of this engine that powers the MiTo Lusso and Veloce has a 0-62mph time of 8.4 seconds and a top speed of 129mph, together with CO2 emissions of 129 g/km and a combined fuel consumption of 50.4 mpg.
The 170bhp MultiAir powerplant fitted exclusively to the range-topping Cloverleaf has a power output of 124bhp/litre which is the highest value ever recorded for a production Alfa.
The MiTo’s Start&Stop technology makes its debut combined with MultiAir engines for the first time on an Alfa Romeo. The system turns off the engine whenever the vehicle is stationary and idling in neutral, then restarts it automatically when the clutch is depressed.
