The good folks at Chrysler have released the new specifications on the 1.4L MultiAir turbo engine that will reside in the 500 Abarth here in the states. Announced at the Detroit autoshow, and thanks to Fiat and Chrysler for searching the Alfa (mito) parts bin, the 1.4L will be rated at an astounding 170 horsepower and 183 lb-ft of torque!
This is an increase over every street going version of the car to date, even 10 more hp and 20+ more torque than the Abarth EsseEsse in EU land.
The US version 1.4-liter turbo
170 horsepower @ 6750 rpm
170 lb-ft of torque @ 3000 rpm
The little US 500 Abarth will have over 120 horsepower per liter, having one of the highest specific power outputs on record for a street car.
Thanks to our friends over at
Fiat 500 USA for the breakdown of this exciting news!
Official Chrysler Press Release
"New Four-cylinder Engines
Four-cylinder engine options are being expanded at Chrysler Group
with the introduction of Fiat Powertrain's 1.4-liter, in-line four-cylinder Fully Integrated Robotized Engine (FIRE) featuring Multiair. In the early 1970s, the use of robotics in assembly plants was not common. The term “FIRE” came into existence when Fiat integrated the use of robotics in the production process of manufacturing plants. Although mechanized assembly is common today, the brand name FIRE has remained with Fiat’s powertrain lineup.
1.4-liter 16V FIRE Turbo
Two variations of the engine will be available, naturally aspirated and turbo. Both versions of the 1.4-liter FIRE feature four valves per cylinder and incorporate state-of-the-art technology for Fully Variable-valve Actuation (FVVA), also known as Multiair. Fiat’s Multiair technology significantly reduces emissions, while improving fuel economy and power. This sophisticated electro-hydraulic variable-valve actuation technology delivers an increase in power up to 10 percent, an improvement in low rpm torque up to 15 percent and a reduction in fuel consumption and emissions up to 10 percent when compared with similar engines without the technology. The Multiair system is based on a series of Fiat Powertrain patents related to hardware, combustion strategies and controls that allow for full control of the lift and timing of engine valves, independently on each cylinder and during each single engine stroke. Well suited for a small car application, the first North American vehicle to feature the 1.4-liter FIRE with Multiair is the Fiat 500.
Specifications:
1.4-liter I-4 FIRE with Multiair
100 horsepower (75 kW) at 6,750 rpm
95 lb.-ft. (129 N•m) of torque at 4,250 rpm
1.4-liter I-4 FIRE Turbo with Multiair
170 horsepower (128 kW) at 6,750 rpm
170 lb.-ft. (231 N•m) of torque at 3,000 rpm"
