Tatra T815 is a truck family, produced by Czech company Tatra. It uses the traditional tatra concept of rigid backbone tube and swinging half-axles giving independent suspension. The vehicles are available in 4x4, 6x6, 8x8, 10x8, 10x10, 12x8 and 12x12 variants. There are both air-cooled and liquid-cooled engines available with power ranging from 230–610 kilowatts (310–820 hp). As a successor to Tatra T813 it was originally designed for extreme off-road condition, while nowadays there are also variants designated for mixed (both off- and on-road) use.
The T815 and its descendant models brought the Czech truck racer Karel Loprais to victory six times in the Paris Dakar Rally.
