Dodge 1.4 MultiAir Turbo specs: 83 ci (1.4L) 4-cylinder, 2.835 x 3.307 in (72 x 84 mm) bore and stroke, 9.8:1 compression. Rated 160 hp, 2013–2016.
The Dodge 1.4 MultiAir Turbo is undersquare — the 3.3071" stroke exceeds the 2.8346" bore by 14.3% — a layout that trades peak RPM for leverage and torque low in the range. The 3.3071" stroke does not reach 4,000 ft/min of mean piston speed until about 7,250 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 20.8 ci (340 cc).
Static compression of 9.8:1 on aluminum heads is moderate for the displacement, which is deliberate on a boosted engine — the turbo supplies the rest of the effective ratio, and static compression plus boost together set the fuel requirement.
4 factory variants share these dimensions, rated at 160 hp across 2013–2016.
