- The British Napier-Railton, which reached a speed of 496.3 km/h (308.4 mph) in 1933
For "most powerful" and "strongest", contenders could include:
- The German Panzer VIII Maus super-heavy tank, which weighed over 188 metric tons and was equipped with a 128mm gun
- The Soviet T-35 heavy tank, which had a crew of 11 and was armed with a 76.2mm gun and two 45mm guns
As for "coolest," opinions vary widely, but some popular choices might include:
- The American Willys MB "Jeep" for its versatility and widespread use
- The British Supermarine Spitfire for its iconic design and effectiveness in air combat
- The Soviet T-34 medium tank for its combination of mobility, firepower and armor protection
Ultimately, the "fastest, most powerful, strongest and coolest" vehicle of World War 2 is a matter of personal preference and perspective, as there were many remarkable machines involved in that global conflict.
