The final tank designs of 1918 showed a number of trends. The joint US and British Mark VIII tank was supposed to be a common heavy tank design for them and the French. The design should have overcome the limitations of the earlier British heavy tanks. The , 37-ton armored vehicle was powered by a 300-hp (224 kW) V-12 engine and capable of 7 mph (11 km/h) cross-country. Although 100 were built, it was the much smaller Renault FT that set the pattern for almost all tanks that followed it; these tanks generally had lower track profiles and more compact hulls, and mounted their weapons in turrets.
