The 2006 Jeep Hurricane concept car had two engines for a total of 16 cylinders. Each engine was a 5.7-liter Chrysler Hemi V8, so the pair produced a combined total of sixteen cylinders.
Jeep presented the Hurricane at the 2005 North American International Auto Show in Detroit, although it is commonly described as a 2006 concept. Its extreme powertrain placed one V8 at the front and another at the rear, giving the vehicle a claimed output of about 670 horsepower.
The Hurricane’s engineering was as dramatic as its styling. It used four-wheel drive and four-wheel steering, allowing the front and rear wheels to work together for tighter maneuvering. Its suspension and body were also designed for serious off-road capability rather than merely show-car appearance.
A frequent source of confusion is the vehicle’s cylinder deactivation system. The engines could shut down cylinders in groups, allowing operation on 16, 12, 8 or 4 cylinders depending on demand. Those selectable operating levels do not change the total: installed, the Hurricane had two V8s and sixteen cylinders.
