The Soviets created the ZIL-E-167 6×6 in 1962 to reach far-north towns in any weather (or to invade the U.S. via the North Pole, if you follow certain conspiracy theories). It's powered by two ZIL-375 3.5-liter V8s positioned at the back. The entire thing measured 30 feet long, 9 feet wide, and 9 feet high (though another source said it was 10 feet wide and 10 feet high). It had a curb weight of 12 or 15 tons and a carrying capacity of 7tons. ¹⁾
