Since 2014, the Brazilian plant has been producing the 1.0-liter Renault H4D or 1.0 SCe engine, which powers vehicles like the Clio and Twingo, as well as the third-generation Dacia Logan and Sandero. This power unit is referred to as HR10DE on a Nissan vehicle and M281 on Smart.
B4A, B4D, H4D, H4M, M4R, M5R, 2TR, V4U, and V4Y are the SCe line.

Disadvantages of the Renault H4D engine
The most important thing is to keep an eye on the cooling system, particularly the rear engine;
A few instances of timing chain replacement on a run of roughly 100,000 kilometers can be found on specialized forums;
Oil consumption happens after 100,000 kilometers because of oil scraper rings; there are no hydraulic lifters, and the valve clearance needs to be adjusted every 100,000 kilometers.
