The data indicates that all Mitsubishi Evo X (2008-12) 4-door saloon models with the GSR FQ-300 SST AUTO6 variant are fitted with a 2.0L petrol engine. Specifically, there is a 100% consistency in engine capacity and primary fuel type across the sample, suggesting that these vehicles uniformly feature 2.0L petrol engines. This uniformity highlights the model's reliance on a specific engine configuration during its production run, which may be useful for prospective buyers or owners seeking accurate vehicle specifications.
