Mahindra's upcoming Vision S compact SUV has been spotted undergoing testing, revealing significant design features and a potential diesel engine. The latest images indicate that the SUV is moving closer to its final production form, with a design that emphasizes practicality over sporty aesthetics. The Vision S maintains a traditional SUV profile with a flat bonnet and chunky wheel arches, which contrasts with many current urban-focused crossovers. Notably, the round headlamp units observed have sparked comparisons to the Mahindra Thar, although the final lighting design may still be modified. Reports suggest that the Vision S could be equipped with a diesel powertrain, positioning it uniquely in a market where few competitors offer diesel options in this category. As the sub-4-metre SUV segment remains highly competitive in India, Mahindra's focus on cabin space and visibility is likely to appeal to family-oriented buyers. While an official launch date has not been disclosed, the continued testing indicates that the vehicle is nearing its final development phase, with more details expected to emerge soon regarding features and engine options.
