The Mitsubishi Outlander and Outlander PHEV delivered in the Automotive Science Group’s (ASG) 2018 Automotive Performance Index™ (API), demonstrating the advanced capabilities of Mitsubishi’s SUV platform. The Outlander, with an EPA estimated 30 MPG highway (25 city/30 hwy/27 combined), outperforms competitors in class by an average 6 MPG highway, sizable fuel economy improvements that reduce fuel costs in the SUV segment, earning ASG’s 2018 BEST 5 ALL-AROUND PERFORMANCE SUV Award.

The Outlander PHEV, with a 22-mile all electric driving range and EPA estimated 74 MPG-e, leverages the increasingly cleaner U.S. power grid as a fuel source, to significantly increase the environmental benefits of the plug-in SUV powertrain in 2018, and across future years. To this end, the Outlander PHEV establishes new benchmarks for performance and value in the SUV segment, earning ASG’s BEST 5 ALL-AROUND PERFORMANCE SUV Award.

ASG’s all-around performance analysis is a comprehensive data-driven assessment, analyzing economic, environmental and social performance indicators across a vehicle’s life-cycle, and in relative comparison to all competitive vehicles in the market.

The Outlander and Outlander PHEV were among the best 5 SUVs assessed in ASG’s 2018 Study, outperforming the average SUV by an astounding 22%. The Outlander lead notable competitors including the Subaru Forester with a 3% advantage, the Hyundai Santa Fe Sport by 6% and the Ford Edge, Nissan Murano and Volkswagen Tiguan by 9% respectively.

ASG found the 2018 Mitsubishi Outlander and Outlander PHEV to offer the best 5 all-around performance and value among all 372 SUVs assessed.

The Automotive Performance Index (API) applies statistical methods to demonstrate each vehicle rating in relative comparison. For example, the vehicle that performs highest in environment performance in a given class obtains a rating score of 100. Each vehicle in its class is then compared relative to the top-performing vehicle with a rating score reflecting the statistical difference in performance outcomes. A score of 91 translates to a 9% environmental performance deficit as compared to the top-performing vehicle.  

Due to the API’s relative vehicle rating method, vehicle class divisions were identified as a critical input - these class divisions are detailed here.

While the Automotive Performance Index is indeed an exhaustive list of vehicles to trim level detail, with each vehicle assessment reporting over 200 unique data outputs (the culmination of thousands of data inputs), ASG has taken additional measures to ease the burden of sorting through all data points and all vehicle assessments. We have developed key performance categories and sorted all vehicles in each class according to Environmental Performance, Social Performance, Economic Performance and All-Around Performance. The vehicle in each class with the best score in each unique category is named the performance award winner (i.e. Best Environmental Performance Award winner). The vehicle in each class that scores highest combined scores in Environmental Performance, Social Performance and Economic Performance is named the ASG Best All-Around Performance Award winner.

One step further, we also name the Best 5 All-Around Performance Award winners in each class to provide consumers with a concise product comparison guide.
