Kamaz also leased 20% more vehicles in the reporting period.
In March 2006, Kamaz sold 3,183 trucks, up 31.2% year on year and the best figure for the start of the year in the past 13 years, the company said.
Kamaz said it had sold 500 more vehicles in March than it had planned due to the expansion of its sales on the domestic market. The company said it exported every fourth or fifth vehicle, depending on seasonal fluctuations.
