GAZelle Business is a family of Russian-made light-duty vehicles produced at the GAZ plant since 2010. The model replaced the classic GAZelle of the 90s. The manufacturer managed to improve the car's performance without making significant design improvements. In particular, the service interval has been increased to 15 thousand km versus 10 thousand previously, and the warranty period has been extended to 80 thousand km or two years.
The reduction in fuel consumption was 5%, and the braking distance was reduced by 8%. In addition to the imported Cummins ISF diesel engine, the main engine for the GAZelle Business family is the gasoline UMZ-4216.10, working with a five-speed manual gearbox. The engine provides a maximum speed of 130 km/h.

Advantages of booms with hydraulic compensators
The UMZ-4216 engine with hydraulic compensators does not require additional maintenance due to the absence of valve clearances throughout the entire period of operation. Because of this, the noise level is noticeably reduced. The highest engine speeds are now not critical, because the design of the hydraulic compensators includes the factor of stabilizing the occurrence of maximum loads. The degree of wear of the mating surfaces of the mechanism parts is significantly reduced. Due to the optimization of gas distribution phases, harmful impurities of exhaust gases are consistently low throughout the entire period of operation.
