The Willys MB was more commonly known as the Jeep. Jeeps, of course, were four-wheel drive vehicles with gutsy engines (and all-terrain ability) that made them indispensable to the Allies.

1. a glider

2. a sports car

The Studebaker US6 was a cargo truck that became vital to supply efforts during World War II. It had a 320 cubic-inch 6-cylinder engine that produced around 86 hp.

1. Willys Avenger
   Willys Stop Evil
2. Willys Go Devil

The Willys L134 engine was better known by the name Willys Go Devil. It didn't have a ton of horsepower, but the vehicle had a heavy transmission that was durable for use in war zones.

1. Sherman tank
   M2 tank
2. Spitfire

Some of the famed British Spitfire fighters had Rolls Royce Griffon engines. They could zoom nearly 400 mph, making them hard targets for the Nazis.

1. about 60 hp
   about 160 hp
2. about 260 hp

The Go Devil was rated at about 60 hp. It also had a torque output of around 105 lb ft. These Jeep engines zipped military men around the front, through all sorts of awful terrain.

1. the engine was inverted
   the engine was very small
2. the engine was armored

The Ilyushin Il-2 fighter had armored plating all through its body, including around the engine. Some of these planes absorbed hundreds of hits and kept right on flying.

   aircraft carriers
2. heavy bombers

Detroit diesel 6051 quad-71 was used to drive propellers, often those on landing craft meant for amphibious assaults.

Almost all World War II trucks used gasoline. Diesel and multi-fuel truck engines didn't become more common until well after the war ended.

1. Germany
   Soviet Union
2. France

Thanks in large part to the Lend-Lease Act, the Soviets were very familiar with American engine technology. They made their own versions of the Series 71, often integrated into trucks and artillery tractors.

   12-cylinder Maybach HL 120 TRM V12
2. 6-cyl Maybach HL 62 TR

The Panzer IV tank was the most common German tank of the war. It relied on its 12-cylinder Maybach HL 120 to move around the countryside.

The GMC 270 engine was used in some of the most common cargo trucks, namely the famous "Deuce and a Half" (2.5-ton) trucks that hauled Allied supplies all over the place.

1. 4 cylinders
   6 cylinders
2. 8 cylinders

The Go Devils sported 4-cylinder engines and manual choke. Altogether, they weighed around 1 ton, too heavy for the Army's taste but still more than capable for the war's needs.

   tanks
2. trucks

The Germans used countless numbers of the Maybach HL230 for a variety of tanks, from the Tiger to the Panther. It was a water-cooled V12 engine.

1. about 800 hp
   about 1,200 hp
2. about 2,400 hp

With fuel injection and a supercharger, the later versions of the Maybach HL230 could hit around 1,200 hp. They powered the Tiger, one of the most-feared Nazi tanks.

1. Supermarine Spitfire
   Messerschmitt Bf 109
2. Ilyushin Il-2

The Germans built their Messerschmitt Bf 109 with an inverted-V12 aero engine. The fact that it was inverted made it less susceptible to enemy fire from below.

1. large planes
   small fighters
2. tanks

The Pratt & Whitney R-1830 was used in large planes, such as the DC-3 transport and B-24 heavy bomber. It became one of the most common engines of the war.

1. about 500 hp
   about 1,200 hp
2. about 8,000 hp

These were powerful engines that created about 1,200hp at takeoff. When cruising, they'd output around 700hp.

1. 6 cylinders
   7 cylinders
2. 8 cylinders

The M2 had a Continental R-670-9A engine, which used a 7-cylinder setup. It was a radial gasoline engine most often built into planes.

1. 250 hp
   600 hp
2. 800 hp

It was built into light tanks, but the Continental R-670-9A still only offered about 250 hp. A lot of these tanks were used primarily for tank crew training purposes, not actual combat.

1. Oil Slick Sally
   Green Devil
2. Rocky Mountain Humming Bird

The engine garnered notable nicknames, like "Rocky Mountain Humming Bird," for the distinctive sound it made when it was running hard. It was also called the "Green Leaker" because it tended to spew fluids.

1. Sherman tank
   Spitfire
2. M18 Hellcat

The Continental R975-C1 was used in the M18 Hellcat tank destroyer. It produced a whopping 400 hp, far more than many other World War II-era engines.

1. unbelievable torque
   great speed
2. excellent gas mileage

The Continental R975-C1 made the M18 Hellcat crazy fast. It didn't have a lot of armor but could top 50 mph, making it the fastest American tank of the war.

1. Mercedes-Benz
   Rolls-Royce
2. Dodge

The Dodge WC Series was a huge array of light trucks made in the hundreds of thousands for the war. They had a horsepower rating of around 90 hp.

1. around 55 mph
   around 75 mph
2. around 95 mph

The WC Series engines weren't overwhelmingly powerful, but they could propel the trucks to about 55 mph. In cases where bullets were flying, that might not have felt fast enough.

1. it was the most reliable engine of the war
   it was tiny
2. it was huge

The Ford GAA engine was the biggest mass-produced gasoline V8 engine on the planet. It was made from around 1940 to 1950.

1. armored trains
   artillery tractors
2. tanks

The GAA was used in many versions of tanks. The 525-hp behemoth was originally 12 cylinders but was reduced to 8 cylinders in some tanks.

1. armored car
   self-propelled howitzer
2. a huge tank

The V8 engine was used in the Leichter Panzerspähwagen, which was an armored car. The engine created about 90 hp, used to move a heavy vehicle that tipped the scales at nearly 9,000 pounds.

1. Ford
   Chevrolet
2. Dodge

The Opel Blitz often featured a 75-hp straight-six engine very similar to the ones found in Chevy trucks. They were so similar, in fact, that Allied troops could use parts from their stockpile to get abandoned Blitz trucks running again.

1. artillery
   trench construction
2. bridge demolition

The 6-cylinder gas Maybach HL 62 TR powered numerous Nazi vehicles, including the Wespe. It was a self-propelled artillery gun that could go nearly 25 mph.

1. about 300 hp
   about 600 hp
2. about 1,900 hp

The Landwasserschlepper used the common Maybach HL120 engine, which produced about 300 hp. The 13-ton monster tractor could carry up to 22 people.
