Chrysler has just released their specifications on the 1.4L MultiAir engine that will equip the Fiat 500 Abarth. The 1.4L MultiAir Turbo will be rated at 170hp, that's up from the standard European spec'd version with 135hp and even up from the optional Esseesse version with 160hp.
The US version 1.4-liter FIRE Turbo with Multiair
170 horsepower (128 kW) @ 6750 rpm
170 lb.-ft. (231 Nm) of torque @ 3000 rpm
That power output, 2.04hp/cu in (124 hp/litre), puts the 1.4L MultiAir Turbo engine as having one of the highest specific power values in the world!
Previously, I speculated that the original Abarth's 135hp wouldn't be sufficient for the US market, based on its competitors (you can read more about that here). I thought a 3 cylinder SGE engine with 157hp or, better yet, the 170hp unit from the Alfa Romeo MiTo Quadrifoglio Verde would be more like it. Well it looks like the Quadrifoglio engine specs won out.
The 1.4 Turbo MultiAir in the 500 Abarth is basically the same engine used in the MiTo Quadrifoglio Verde, except for some packaging and tuning details. The Quadrifoglio Verde does put out more torque:
Alfa Romeo MiTo Quadrifoglio Verde
170 horsepower (128kW) @5500rpm
170 lb.-ft (230Nm) of torque @ 2500 rpm in normal mode
184 lb.-ft (250Nm) of torque @ 2500 rpm in sport mode
The Quadrifoglio Verde will have a new, heavy duty 6 speed transmission called the C635, that can cope with the increase in torque. Currently the 500 Abarth has a heavy duty 5 speed C510 transmission. Could we in the US get the 6 speed from the larger Quadrifoglio Verde? That would be great, but that's a story for another day...
This is good news for us who are waiting patiently for the Abarth version, which is currently expected fourth quarter 2011/beginning 2012.
Below is a list of engine specs from the current 500 Abarth lineup available in Europe:
Standard Fiat 500 Abarth

Below is the 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
